Gemma 4 12B

Google drops Gemma 4 12B, an encoder-free multimodal local model

Google released Gemma 4 12B, an encoder-free multimodal model under Apache 2.0 that targets 16GB VRAM local setups. Instead of bolting separate vision or audio encoders onto a language model, it uses one unified network, which LDJ and Yam argued makes smaller multimodal models cheaper, cleaner, and easier to run locally.

Ideogram 4.0

Ideogram 4.0 becomes the top open-weight text-to-image model

Ideogram released Ideogram 4.0, a 9.3B-parameter text-to-image model with open weights under a non-commercial license. It leads open-weight image models on typography and layout, with bounding-box/layout-style prompting that trades casual generation ease for precise structured control.

Mellum 2

JetBrains open-sources Mellum 2, a 12B MoE coding model

JetBrains released Mellum 2, a 12B mixture-of-experts coding model with only 2.5B active parameters, trained from scratch by a small team using a three-stage curriculum over 10T tokens. The panel read it as IDE companies converting years of developer-workflow context into model advantage; it is also available on CoreWeave Inference.

MAI-Code-1-Flash

Microsoft ships MAI-Code-1-Flash into GitHub Copilot

Part of the seven-model MAI launch at Build 2026, MAI-Code-1-Flash is Microsoft AI's fast coding model and ships directly into GitHub Copilot. The panel saw it as a sign Microsoft intends to serve its own models inside its developer surfaces instead of relying solely on OpenAI.

MAI-Thinking-1

Microsoft launches MAI-Thinking-1, a 1T MoE trained from scratch

Microsoft AI used Build 2026 to launch seven MAI models, headlined by MAI-Thinking-1, a 1T total, 35B active MoE reasoning model trained from scratch on 33T tokens without distillation. The panel read the launch as Microsoft becoming a frontier model lab in its own right rather than only an OpenAI distribution channel.

MiniMax M3

MiniMax announces M3 coding/agentic model with 1M context

MiniMax announced M3, a natively multimodal coding and agentic model with a one-million-token sparse attention context claim and open weights promised soon. Reported numbers include 59 on SWE-bench Pro, and the panel noted MiniMax already has a following for cheap agentic tool calling even as pure coding quality is debated.

Nemotron 3.5 ASR

NVIDIA ships Nemotron 3.5 ASR, a 600M streaming speech model

NVIDIA released Nemotron 3.5 ASR, a 600M-parameter open multilingual streaming speech-to-text model aimed at voice agents. It supports 40 languages and reportedly delivers 17x more throughput than Parakeet-style baselines at half the size, pushing the latency/accuracy frontier for open voice-agent infrastructure.

Nemotron 3 Ultra

NVIDIA releases Nemotron 3 Ultra, a 550B open-weight MoE for agents

NVIDIA dropped Nemotron 3 Ultra the day of the show, a 550B-parameter sparse MoE with 55B active parameters built for long-running agentic harnesses like OpenCode, Hermes, and OpenClaw. Chris Alexiuk joined to explain the hybrid Mamba/Transformer architecture and the unusually complete open release: weights, training data, recipes, a GenRM reward model, and an NVFP4 quantized checkpoint.

Reve 2.0

Reve 2.0 hits #2 on Text-to-Image Arena with layout-first editing

Reve 2.0 jumped to second place on Text-to-Image Arena (around 1200 ELO) with native 4K output, code-like layout control, and precise editing. Alex's live tests found inconsistent portrait identity, but the layout-first editor is the real differentiator for graphic and image iteration workflows.

Grok Imagine Video 1.5 Preview

xAI releases Grok Imagine Video 1.5 Preview with synced audio

xAI released a preview of Grok Imagine Video 1.5, an image-to-video model that generates clips with synchronized audio. It adds xAI to the week's crowded race of media-generation model updates.

Hermes Desktop

Nous Research launches Hermes Desktop agent app for Mac/Win/Linux

Nous Research launched Hermes Desktop, packaging the Hermes Agent harness into a native desktop app for Mac, Windows, and Linux. Karan previewed chat, permissions, tool-call visibility, reasoning traces, and admin controls aimed at small teams, startups, and personal agent fleets.

RTX Spark

NVIDIA announces RTX Spark Arm + Blackwell platform for local AI PCs

At Computex, NVIDIA unveiled RTX Spark, an Arm CPU plus Blackwell GPU PC platform with 128GB unified memory targeting local AI agents and 120B-class local inference. A wave of thin laptops with RTX 5070-class GPUs and roughly one petaflop of local AI compute raises the question of what agents should run locally versus in the cloud.

Major Features & Updates

WolfBench Token-Usage Visualization

WolfBench adds 3D token-depth bars to show model efficiency

Wolfram Ravenwolf shipped a WolfBench feature that visualizes token usage alongside benchmark score as 3D token-depth bars. Two models can look close on a leaderboard while one burns dramatically more tokens, which changes the real cost and latency story; Gemini 3.5 Flash and GPT 5.5 were compared as examples.

Benchmarks & Evals

Agent Arena

Arena launches Agent Arena for real-world agent workflow evals

Arena (LMArena) launched Agent Arena during the episode, moving beyond one-turn chatbot preference battles to evaluate models on real agent workflows with web search, files, terminals, user corrections, and objective recovery signals. Peter Gostev joined live to explain why long-running, harder tasks need a different benchmark.
