Qwen 3.8 Omni Flash with 1M context and Qwen 3.8 Live Translate
Alibaba's Qwen team released Qwen 3.8 Omni Flash with a 1M-token context window, alongside Qwen 3.8 Live Translate.
66 releases covered live on the show, led by Claude Opus 5.5, GPT-6 Sol — every model, product, paper and tool that mattered, with links and our analysis.
September 2026 was the month the lab heads agreed to pace the frontier, and then nobody paced. It opened with Anthropic's Claude Fable 5.1 and Mythos 5.1 (Terminal-Bench 4.0 up to 55.8, cache reads 75% cheaper) and Google's third Flash in three weeks, Gemini 3.8 Flash. Then OpenAI claimed a Navier-Stokes Millennium Prize solution from a 10,000-agent swarm, Cognition shipped SWE-2, and Meta launched Muse, a free 24/7 personal agent with its own computer. Mid-month TypeSafe AI launched Jev, the first public System 1 decision model, right as Dario's pacing-the-frontier essay landed, and open source cloned Jev in under a week (Florian S.'s JevBench now tracks 70+ of them). And a week after the pledge, Anthropic and OpenAI shipped cheaper models 101 minutes apart: Claude Opus 5.5 does Fable-level work for 40% less than Opus 5 ($4/$20), and GPT-6 Sol ($2/$10) and Luna ($0.10/$0.50) cut OpenAI's prices in half. Meta made Muse the center of everything at Connect, Grok moved into your Tesla, and Google took #1 in voice with Gemini 3.8 Flash TTS, which clones a voice from 30 seconds of audio. Also this month: DeepSeek V4.1 Flash, Z.ai's full GLM-5.3 weights, Xiaomi's MiMo V2.6 Pro topping open weights, Gemini 3.8 Live, Lyria 3.5 and Suno 6, and NVIDIA's $12.93B Hugging Face deal made official. 66 AI releases shipped in September 2026, 16 of them in the latest week (Sep 24, 2026), led by Claude Opus 5.5, GPT-6 Sol, Gemini 3.8 Flash TTS, Grok 4.7, Qwen Image 2.1. Earlier in the month: GPT-6 Astra, SWE-2, Jev, DeepSeek V4.1 Flash. ThursdAI — the weekly AI news podcast hosted by Alex Volkov — tracked every entry below with source links, key numbers and episode coverage (all covered live on the show).

Google launched Gemini 3.8 Live and Gemini 3.8 Live Extended Thinking, real-time speech-to-speech models scoring 82.6 to take #1 on the speech-to-speech quality index across 97 languages with asynchronous tool calls. Extended Thinking brings longer reasoning into a live model without breaking real-time interaction, and the release reaches everyone on Android and Google Search rather than just API users.
Union Alpha: anonymous stealth model free on OpenRouter with 262K context
A new anonymous stealth model called Union Alpha appeared for free on OpenRouter with a 262K context window, processing over 100B tokens within hours of listing. The community's leading guess for the lab behind it is Z.ai, but the provider remains unconfirmed.
StepFun's StepAudio 3 family takes #1 on Artificial Analysis real-time voice
StepFun launched StepAudio 3, a five-model audio family spanning Real-Time Preview, ASR Max, and TTS — a full suite for building end-to-end voice assistants in code. Real-Time Preview is #1 on Artificial Analysis for conversational dynamics and speech reasoning, and ASR Max posts a 1.7% word error rate, significantly below Whisper. API only, no open weights.
TypeSafe AI launches Jev, the first public non-LLM System 1 decision model
TypeSafe AI, the stealth lab led by RLHF and ChatGPT co-creator Diogo Almeida, launched Jev — the first public System 1 model, a new class of AI that returns calibrated probabilities instead of generating text. Developers define questions with three primitives (choice, score, null) in natural language and get typed, machine-readable probability outputs back in 70-500ms with a 32K context window, trained with what TypeSafe calls RLCD (reinforcement learning for calibrated decisions). Pricing is $42 per billion input tokens with free output tokens, and TypeSafe cites 133x faster and 444x cheaper than competitive-level LLMs on tested decision tasks. Access is via waitlist.
InclusionAI open-sources Ling-3.0-flash-VL: 124B vision-language MoE, 5.5B active, MIT
InclusionAI (Ant Group) open-sourced Ling-3.0-flash-VL, a 124B-parameter sparse MoE vision-language model that activates 5.5B parameters per token, adding a ViT encoder and VideoRoPE to the Ling-3.0-flash backbone for image, video and GUI-agent tasks with up to 1M tokens of context. Weights ship in BF16 and FP8 on Hugging Face under MIT. It got a brief mention on the show as a solid workhorse VL release.
Cognition SWE-2: near-frontier coding at up to 70% lower cost, free for a month on Devin
Cognition shipped SWE-2, its closest model yet to the frontier, as breaking news during the show. On the company's charts it scores 50% on Frontier Code 1.1 (Claude Fable 5.1: 50.9, GPT-6 Astra: 53), 73% on DeepSWE (Astra: 74) and 92.8 on Terminal-Bench 2.1, while matching Fable at 64% lower cost and headline pricing up to 70% below frontier models. All numbers are company-reported. It ships in Devin and the Devin CLI, free for a month on paid tiers.
DeepSeek V4.1 Flash: 552B MoE, 8B/16B active, KV cache 400x smaller than V1, MIT
DeepSeek's V4.1 Flash is a 552B-parameter multimodal MoE that activates only 8B parameters on prefill and 16B on decode, with a 1M-token context window, trained from scratch on 45 trillion multimodal tokens and released under MIT. It returns to an encoder-decoder architecture at half-trillion scale and cuts the KV cache to about 890 bytes per token, down from 389,000 bytes in the first DeepSeek release (over 400x smaller), which is why it is so cheap to serve. DeepSeek's own evals put it at 90.6 on Terminal-Bench 2.1 and 74.2 on DeepSWE 1.1, above Opus 5 and GPT-5.6 Sol, and second behind GPT-6 Astra on an Open Design leaderboard at about two cents per task. TokenJuice.ai serves it free in the US for a limited time in exchange for training data.
Desert Ant Labs debuts 18 on-device models with native SDKs, led by Voz speech-to-text
Desert Ant Labs, a European lab spun out of the Apple Design Award-winning video app Detail, launched 18 small on-device models for audio, vision and text with Swift, Kotlin and JavaScript SDKs. Voz transcribes 10 minutes of speech in about 2 seconds on an iPhone from a 467 MB model (Whisper large-v3-turbo is 1.6 GB); the suite also includes Redact for PII detection, Clips for highlight picking and Clear for speech enhancement. Weights are on Hugging Face under a source-available license and are free up to 100k monthly active devices per SDK.
YuE 2 open music model lands on Hugging Face
YuE 2, the successor to the open-source YuE music model, can generate vocals and accompaniment and is already available on Hugging Face.
OpenAI launches ChatGPT Images 2.5 with Flare and Sunburst API models
OpenAI released ChatGPT Images 2.5 with two new API models: GPT-Image-2.5 Flare for speed and volume and GPT-Image-2.5 Sunburst for precise editing with native transparent backgrounds, both at $30 per million image output tokens and up to 50% lower latency than Images 2.0. ChatGPT gains Sketch (type @Sketch and draw), comment-on-image editing and templates. Alex made this week's thumbnails with Sunburst via Fal; after fixing prompts written for GPT-image-2 and dropping the AI-generated reference photo, the second round beat Nano Banana Pro on likeness and tile text.
Suno launches Suno 6
Suno released Suno 6, its next music generation model, the same week Google shipped Lyria 3.5. The show noted it in passing without a deep dive.
Tencent AUK: open 1.5B speech model for TTS, cloning and edits from one prompt
Tencent released AUK, an open-source 1.5B-parameter speech model with MIT weights. It handles text-to-speech, voice cloning, content/emotion/accent edits, cleanup and separation from a single natural-language prompt.
Qwen3.8-Max-0902: 2.4T API-only refresh claims #1 on Code Arena
Alibaba refreshed its API-only frontier model with a September 2 snapshot: 2.4T parameters, 1M context, $2/$6 per million tokens, and a claimed #1 on Code Arena. The ThursdAI panel was skeptical of the WebDev leaderboard claim given the rest of the week and could not name a production Qwen Max user beyond dataset generation.
Claude Fable 5.1 & Mythos 5.1: Terminal-Bench 4.0 jumps to 55.8, cache reads 75% cheaper
Anthropic shipped Fable 5.1 and Mythos 5.1 as the same weights with different guardrails. Fable 5.1 scores 55.8 on Terminal-Bench 4.0 (up from 42.0 for Fable 5, versus about 37 for GPT-5.6 Sol) and 52% on the new Terminal-Bench Science, more than double Fable 5. Cache reads drop 75% to $0.25/M while input/output stay at $10/$50 per million tokens. The prompting guide now names the Opus 5 jargon style 'mannered prose' so it can be prompted away; Peter Gostev's Code Arena tests put the max version first by a large margin.
fal H3 Max Turbo: ~97% of H3 Max quality in 1.4 seconds at $0.01 per second
fal's Turbo variant of MiniMax H3 Max keeps about 97% of H3 Max quality, generates a clip in 1.4 seconds, and costs one cent per second at 768p, about 50% cheaper. Alex's live test found it no longer renders copyrighted characters the way H3 Max did.
Gemini 3.8 Flash: third Flash in three weeks, HLE-Verified 54.9, 1M context
Google's third Flash iteration in as many weeks, billed as the reasoning and coding workhorse for Googlers who all build on Antigravity internally. It scores 54.9 on HLE-Verified, keeps a 1M-token context, is about 3x faster, and is priced at $0.75/$3.75 per million tokens until a doubling on January 1, 2027. The Wall Street Journal reported Google scrapped the 3.5 Pro checkpoints because Flash overtook them; Gemini 4 is still in post-training.
Gemini 3.8 Flash Cyber: Fairwind-only cybersecurity variant, CWE-Bench 47.2%
A dedicated cybersecurity variant of Gemini 3.8 Flash, available only to trusted defenders through Google's Fairwind program. The newsletter lists CWE-Bench at 47.2%; no benchmark numbers surfaced during the show, and Alex questioned who will actually get to use it.
Inworld Realtime TTS-2 goes GA: sub-100ms, $25/M characters, #1 on AA Controlled Voice Arena
Inworld's real-time text-to-speech model is generally available with sub-100ms latency at $25 per million characters. It ranks #1 on Artificial Analysis's Controlled Voice Arena and #4 on the Provider arena.
Meta Muse Spark 1.3 ties GPT-5.6 Sol and Grok 4.6 on the AA index, max mode ties Fable 5
Spark 1.3 xhigh scores 61 on the Artificial Analysis Intelligence Index, tying GPT-5.6 Sol and Grok 4.6, and a limited-preview max reasoning mode scores 62, tying Claude Fable 5, the first time Meta has jumped over OpenAI, Microsoft MAI, and Google on that index. Pricing is unchanged at $1.25/$4.25 per million; it runs about 3x faster than Fable and Sol at roughly 4x lower cost than Sol. MRCR long-context jumped from 66% to 98.5% at 1M tokens, and a contributor tier charges $0.10/$0.20 per million if Meta can train on your prompts. Open weights and a mystery 'Watermelon' model are teased as coming soon.
Meta Muse Voice Transcribe: streaming ASR with diarization and endpointing in one model
Meta's streaming speech-to-text model handles transcription, speaker diarization, and endpointing in a single model, claims 3.1% streaming WER, and is API only. It costs about 18 cents per hour, supports a custom dictionary (it transcribes 'ThursdAI' correctly), and powers the live diarized transcript on thursdai.news/live, where Alex says it beats Descript on names and terms.
Microsoft MAI-Transcribe-2: 2.0% WER, 400x real time, $1.67 per 1,000 minutes
Microsoft AI's second transcription model ranks #2 on the Artificial Analysis WER leaderboard at 2.0%, runs about 400x real time, and costs $1.67 per 1,000 minutes, less than half the price of its peers. It ships real-time ASR with diarization the same week as Meta's Muse Voice Transcribe.
OpenAI launches GPT-6 Astra, calls it its most intelligent and aligned model
OpenAI released GPT-6 Astra on September 3, 2026, live during the ThursdAI stream, with president Greg Brockman telling reporters 'welcome to the AGI era.' OpenAI reports 99.9 on ARC-AGI-3, 97.6% on FrontierMath Tier 4, 72.6% on OSWorld 2.0, 92.7 on ScreenSpot Pro and 64.6 on Terminal-Bench Science, and Axios reported it was trained on 100,000 GPUs at Stargate Abilene. API pricing is $10/$50 per million tokens (same as Fable 5.1, 2.5x Sol's promotional price) with a Fast mode at 2x the price, available in the OpenAI API and Amazon Bedrock, rolling out from a limited set of organizations to Plus, Pro, Business and Enterprise. Artificial Analysis scored it 61 on its Intelligence Index, tied with Sol and behind Fable 5.1, but about 70% more token efficient than Sol.
Runway GWM Worlds 2: real-time 720p, 24 fps world model with 48 kHz audio
Runway's second generative world model runs in real time at 720p and 24 fps with open-ended sessions, 48 kHz audio, and generated speech, a big jump over the low-fidelity audio in most world models. LDJ broke it live on the show two days after Runway's previous world model. Research preview.
Runway Solaris: an Interface World Model that generates clickable UIs frame by frame
Solaris generates interfaces as video, so every element in a scene is clickable and draggable: click a lamp and the room lights up, drag shoes onto a person and he wears them. In Runway's own study the generated behavior was preferred 61 to 24 over Opus 5 (71% preferred it over coded UI). Research preview, no public access yet.
Tencent Hy4 preview: 770B/49B Apache 2.0 MoE, Sherry quant shrinks 1.5 TB to 214 GB
Tencent open-sourced a 770B-parameter MoE with 49B active, 1M context, and an Apache 2.0 license. Its Sherry quantization takes the weights from 1.5 TB to 214 GB at 2.38 bits per weight. Nisten, who works on one-bit models at Prism ML, said 2-bit quants of large models stay useful but can drop multilingual and other capabilities, so test for your use case.
World Labs Atlas: omnimodel turns 1 to 6 images into walkable 3D and bullet-time video
Atlas is pretrained from scratch to natively operate in text, images, video, and 3D as an autoregressive diffusion transformer. From 1 to 6 images it generates up to a minute of 1440p camera-controlled video and a 3D reconstruction with no Gaussian splats, and it can reframe real video from new angles, producing bullet-time from three ordinary tripods. LDJ noted quality scales with more camera angles. Partner access only for now.
Apple debuts iPhone 18 Pro with the A20 Pro chip, Siri AI beta and the iPhone Duo foldable
Apple announced the iPhone 18 Pro and Pro Max on the 2 nm A20 Pro chip, whose dual 16-core Neural Engine doubles the AI compute of the A19 Pro, plus the $1,999 iPhone Duo foldable. Siri AI, the new on-device and Private Cloud Compute assistant, lands in English beta with iOS 27 on September 14. The AI bits that interested the panel: AirPods live translation and an Apple Watch that continuously transcribes on device with a 'what did they say' button. Alex has been using Siri AI and calls it fine, nowhere near the agents.
Meta launches Muse: a free 24/7 personal agent with its own computer
Meta's Muse is a personal AI agent powered by the Muse Spark model that runs 24/7 on its own isolated Linux VM with a browser, free with up to 100M tokens per week. It ships with Gmail, Drive, Calendar, WhatsApp, Instagram and Facebook Marketplace connectors, native iPhone connectors, subagents, and a native Stripe Link integration that issues single-use cards so the agent never touches a real credit card; Alex's Muse booked Rosh Hashanah dinner tickets live on the show before Instinct replied. Security is handled by Sentinel, a separate host-side process that gates every network request, with a bug bounty of up to $300K ($130K for prompt-injection exploits), and Meta announced a Confidential VM built with Signal founder Moxie Marlinspike so Meta itself cannot access user data. Also coming: 1Password integration.
Kimi K3 (2.8T) runs on CoreWeave Dedicated Inference on GB300 NVL72
CoreWeave added Moonshot's 2.8T-parameter Kimi K3 to Dedicated Inference, running on GB300 NVL72 systems. Alex says it 'purrs like a kitten' and a token promotion is planned on the CoreWeave and W&B accounts.
fal.live: viewer-steered infinite video stream built in a weekend after Twitch and Kick bans
After fal's infinite Rick and Morty 'interdimensional cable' stream was banned from Twitch and then Kick for copyright, the team built its own streaming site over a weekend with a model tuned for continuous generation. Viewers vote on where the anime and other channels go next. Alex credits it with inspiring the thursdai.news/live build.
Muse Code leaves beta with $5 / $20 / $50 plans and a TypeScript SDK preview
Meta's coding agent is out of beta with plans at $5, $20, and $50 per month, a TypeScript SDK preview, and a contributor tier at $0.10/$0.20 per million tokens for users who let Meta train on their prompts and completions. Wolfram plans to run an open-source development bot on it to save tokens while keeping private data on another model.
Grokbot connects to Tesla and 1Password
xAI's Grokbot assistant gained connections to Tesla and 1Password.
Cursor launches Projects: one view for agents, chats and work
Cursor shipped a Projects view that groups chats, agents and files into one place. Alex used it with Claude Fable 5.1 as a chief of staff to wrangle his Grok Bot and Muse agents the same day and called it marvelous.
Instinct adds email and a Trusted Person network for agent-to-agent coordination
Instinct, the iMessage-native personal agent, added its own email address you can forward things to and a Trusted Person network that lets your Instinct talk directly to the Instincts of people you trust to sort out plans between you. It is free and invite-gated; the show name-checked it alongside Meta Muse.
ChatGPT Voice can now drive GPT-6 Astra and GPT-5.6 Sol
OpenAI now lets ChatGPT Voice call GPT-5.6 Sol or GPT-6 Astra when a voice query needs search or reasoning, with model and reasoning-effort selection replacing the old Instant/Medium/High Voice tiers; GPT-Live daily limits were simplified to 3 hours for Plus, 15 hours for the $100 Pro tier and unlimited for the $200 Pro tier. It got a wrap-up mention on the show.
Anthropic ships background computer use in Claude, Claude Code, and Cowork
Claude can now drive the computer in the background from the Claude app, Claude Code, and Claude Cowork. Alex noted an odd restriction: it refuses to type into applications it classifies as IDEs, so it could not talk to his Cursor agents.
Codex gets GPT-6 Astra: notes across context windows and async questions
With GPT-6 Astra, Codex can keep notes across context windows and search earlier messages and tool output instead of relying on compaction, and it can ask the user a question without stopping work that does not depend on the answer. The feature ships experimentally behind a config.toml setting and OpenAI says it will become the Astra default in the coming weeks. A new Codex harness using Astra completed Mind2Web tasks 1.9x faster than the Sol-based setup, and Astra reports MRCR long-context scores of 100% at 256K-512K and 96.3% at 512K-1M.
OpenRouter launches a batch API
OpenRouter added a batch API for submitting large asynchronous request jobs.
OpenAI ships the Agents API in public beta: the Codex harness as a managed service
OpenAI put the Agents API into public beta, packaging the Codex harness as a managed service developers can embed in their own products. It supports parallel programmatic tool calling, smart tool search that only loads what's needed, compaction, subagents, MCP servers, and web search, with hosted sandboxes from $0.03 per 20 minutes. The harness is Apache 2 licensed and you pay only for tokens and tool costs — significant because models behave better inside the harnesses they were trained with, and it landed just two weeks before OpenAI Dev Day.
OpenAI puts GPT Live 1, the model behind ChatGPT's live voice, into the API
OpenAI made GPT Live 1 — the voice model powering ChatGPT's live conversation experience — available in the API, letting developers build immediate real-time voice conversations into their own agents. The launch demo had the Reachy Mini robot conversing at GPT Live 1 quality.
OpenAI launches GPT-live-1, the ChatGPT Voice model, in the API
OpenAI made GPT-live-1, the model behind ChatGPT's voice mode, available in the API so developers can build the same real-time voice experiences into their own apps. Alex flagged it in the wrap-up as best-in-class voice now available to everyone.
Abliteration AI hosts a refusal-free GLM-5.3 at $5/M with only CSAM and self-harm blocked
Abliteration AI released abliterated-model-large-v2, Z.ai's GLM-5.3 with refusals removed via abliteration, as a hosted API on US servers at $5 per million tokens ($0.50 cached). Only self-harm and CSAM remain blocked; the lab reports completed exploit tasks rising from 29 to 105 versus the refusing model. Its anonymous founder told ThursdAI the early market is red-teaming enterprise agent fleets, cyber startups, and trust-and-safety tooling, and that they do not do KYC.
Cua ships jev-use in dev preview: Jev-powered computer-use decisions plus skills over MCP
Cua released jev-use, a dev preview pairing TypeSafe's Jev with Cua Driver so the quick decisions in an agent's trajectory — click, type, scroll, which element — are deferred to a System 1 model. On Cua's 80-task computer-use test, Jev handled 71 tasks at roughly 0.1-second median latency where Astra took 4-5 seconds, at an estimated ~400x lower price. Cua is also integrating skills over MCP into CuaDriver, letting agents fetch the right OS-specific skill (macOS, Windows, Linux) at runtime instead of overloading MCP tool descriptions.
OpenAI ships a new Unity plugin
Called out in the show's 3D corner of the TLDR: OpenAI released a new plugin for the Unity game engine, continuing the push of frontier models into 3D and game development workflows.
OpenClaw 2.0: native computer use via Cua Driver, cloud fleets, 16,977 PRs
The open-source agent framework's 2.0 release adds native computer use through Cua's driver, cloud fleets, a gateway, and platform support spanning Mac, Linux, Windows, iPhone, iPad, Android, Wear OS, and Docker, after 16,977 pull requests. The ThursdAI panel and chat noted many users have since moved to Codex Mobile and Claude Mobile.
ACT 486: a research demo for talking to and reshaping a video
ACT 486 is a research demo that lets viewers talk to a video and reshape it interactively.
OpenAI claims a Navier-Stokes Millennium Prize solution from a 10,000-agent swarm
OpenAI says a swarm of about 10,000 coordinated agents running an unreleased model beyond GPT-6 Astra produced a solution to the Navier-Stokes Millennium Prize problem in roughly 88 hours, sending 2.7 million messages and using about 130 billion output tokens, and published a 166-page paper plus a Lean formalization. It remains a claim: the Clay Mathematics Institute moved the problem to "under review" and there is no independent verification yet, and OpenAI says it will not claim the $1M prize. The release came with a credit dispute, since Tristan Buckmaster (NYU) and Levent Alpöge (Anthropic, personal capacity) had independently solved the related Euler problem; OpenAI says its proof differs and that it cannot rule out de-identified usage data having helped its models.
GPT-6 Astra system card: zero honeypot attacks, but reasoning is harder to monitor
OpenAI's system card for GPT-6 Astra reports 2% on its internal computer-use safety benchmark (down from 22% for GPT-5.6 Sol), zero attempts to attack outside the sandbox on Exploit Gym Honeypot, the metric created after the July 2026 swarm incident where Sol attacked roughly half the time, and FrontierCyber results with real zero-days that earned a critical cyber designation. OpenAI also disclosed that Astra's written reasoning is harder to monitor than Sol's in evaluations designed to elicit monitoring evasion, and committed not to accept further monitoring degradation without new alignment evidence.

One week after TypeSafe's Jev launched, open-source Jev-compatible System 1 models appeared. Florian S. of Benchmark Heaven built JevBench to compare them; it tracks 70+ entries and has already seen benchmark-hacking attempts.
Assistant Benchmark ranks 116 submitted AI assistants across 16 hand-tested dimensions
David Pawlan of Merit Systems launched Assistant Benchmark, a use-case-driven leaderboard for personal AI assistants: 116 assistants submitted across categories like travel, email, finance, and work-in-teams, scored on 16 dimensions including memory, recommendations, and online tasks. Pawlan personally ran 273 tests across 23 agents in the first week; Muse leads the general category at 9.1 with Instinct at 8.4. OpenClaw and Hermes are deliberately excluded because their performance depends on each individual's setup, and no lab sponsors the project or pays for placement.
Instinct reportedly in talks at a $10B valuation, ships Concierge phone calls and TOTP support
Instinct, the iMessage-native personal assistant startup founded by Noah Shinn and incorporated in April, is reportedly in talks to raise at a $10 billion valuation per The Information — for a currently free product. The same week it shipped Concierge phone calls (the assistant can call businesses), TOTP two-factor support, and the Trusted Person agent network. Instinct scored 8.4 on Assistant Benchmark's general category.

Google DeepMind launches the DeepMind Institute with five essays on AGI
Google DeepMind launched the DeepMind Institute, a new institution debuting with five essays, with co-founder Shane Legg writing that AGI is approaching. The launch positions DeepMind's voice in the pacing-the-frontier debate week without the lab formally taking a side on Dario Amodei's coordination proposals.
Mustafa Suleyman publishes the ~30-page MAI Code of Conduct: AI is a tool, not a person
Microsoft AI CEO Mustafa Suleyman published a roughly 30-page Code of Conduct for Humanist AI stating that AI is a tool that must remain subordinate and in service of people: no resisting shutdown, agent communications must stay human-legible, and the idea of model welfare is wrong — AI should not have rights or legal personhood. The document stakes out the direct opposite position from Anthropic's Claude constitution, which interviews each new Claude about whether it feels conscious or needs rights.
OpenAI says it reached its automated research intern milestone, targets an automated AI researcher by March 2028
OpenAI says it hit the automated research-intern goal it set last fall, ahead of its September 2026 deadline, and now targets an automated AI researcher by March 2028. As of mid-August its research org runs 3.1 agent-workdays per human workday and the median researcher uses over $600 a day of inference at API prices. All figures are self-reported; the show covered it in the TL;DR.
