Claude × Salesforce collaboration
Claude and Salesforce announce a collaboration
Anthropic's Claude and Salesforce announced a collaboration — the only notable frontier-lab news in an otherwise release-free week for the big labs.
Anthropic AI Releases: Claude Code /design, Claude-designed protein binders & Claude output watermarking
Anthropic's coverage centers on the Claude family — the Opus 4.x-to-5 frontier line and the Sonnet models — plus a steady stream of Claude product, API and agent-tooling updates. ThursdAI — the weekly AI news podcast hosted by Alex Volkov — has covered 52 Anthropic releases since Jan 2025, most recently Claude × Salesforce collaboration on Aug 27, 2026. Highlights include Claude Opus 4.5, Claude Opus 5, Claude Mythos, Claude Opus 4.7. 2 of them shipped with open weights. Every entry below has the episode segment where we covered it live, plus primary-source links and key numbers where we have them.

Claude output watermarking
Anthropic watermarks all new Claude text output worldwide
Anthropic began watermarking all new Claude text output worldwide to comply with EU AI Act Article 50, delivering EU compliance globally rather than region-by-region, with C2PA marking on images. Detection documentation is promised; Jonas Geiping published an FAQ on how the watermarking works.

Claude Opus 5
Anthropic ships Claude Opus 5 at unchanged Opus pricing, claiming near-Fable-5 performance at half the cost
Anthropic launched Claude Opus 5 at $5/$25 per million input/output tokens — unchanged from Opus 4.8 — with a new five-level effort toggle (low/medium/high/xhigh/max) and a 1M-token context window per Anthropic's platform docs. On Frontier-Bench v0.1 it leads all models and more than doubles Opus 4.8's score at lower cost per task; on CursorBench 3.2 it lands within 0.5% of Fable 5's peak at half the per-task cost, and it scores 3x the next-best model on ARC-AGI 3. Anthropic's own card notes it scores 2.3 on overall misaligned behavior (lowest of its recent models) but still trails Mythos 5 on cybersecurity exploitation. It now anchors Claude Max by default — Anthropic's fourth Claude 5-series model in under two months, after Sonnet 5, Fable 5, and Mythos 5.

AMD MI450 / Helios capacity deal
Anthropic signs an AMD compute deal: up to 2GW of MI450/Helios capacity, with up to $5B in AMD equity
Covered on the Jul 23 live show: Anthropic and AMD struck a capacity agreement giving Anthropic access to up to 2 gigawatts of MI450/Helios-generation compute, a deal that includes up to $5 billion in AMD equity — landing the same week AMD's Advancing AI 2026 event launched the Helios/MI400 platform and reports surfaced of separate Meta/Anthropic compute-lease talks (~$10B over two years). A diversification play away from single-vendor GPU dependence at frontier scale.

Jacobian Conjecture counterexample (Fable 5)
Mathematicians credit Claude Fable 5 on an explicit counterexample to the 87-year-old Jacobian Conjecture
Levent Alpoge — prompted by a suggestion from Akhil Mathew — produced an explicit three-dimensional counterexample to the Jacobian Conjecture, open since 1939, crediting Claude Fable 5 as a collaborator in finding it. Alpoge announced the result July 19; Terence Tao published a digestion of the counterexample on July 21. Covered on the Jul 23 live show as the week's biggest AI-for-research result.

J-space (global workspace research)
Anthropic finds a global workspace inside Claude: the J-space
Using a Jacobian-based interpretability technique (the J-lens), Anthropic identified a small internal subspace — about 25 active concepts, under 10% of activation variance — that behaves like the global workspace from consciousness neuroscience. Ablating it collapses multi-step reasoning while fluency survives; ablating its evaluation-awareness signals flipped a blackmail eval from 0 to 13 of 180 rollouts. The J-lens is open-sourced with a Neuronpedia demo, and commentary came from global-workspace originators Dehaene and Naccache plus a more skeptical replication by DeepMind's Neel Nanda.

Fable 5
Fable 5 restored globally after the export-control pause
Anthropic restored Fable 5 (and Mythos 5) globally on July 1 after US export controls were lifted, adding cybersecurity classifiers as 'the strongest safeguards'. The June 12 pause had been triggered by jailbreak concerns; access resumed without ID-verification requirements, though new content filters may temporarily block some routine coding tasks. Alex celebrated by having Fable prep the entire ThursdAI run of show.

Sonnet 5
Claude Sonnet 5: 'our most agentic Sonnet yet' at intro pricing
Anthropic launched Sonnet 5 with near-Opus 4.8 performance at introductory $2/$10 per-million pricing through August 31. Reception split sharply: power users saw near-Opus costs for marginally inferior output at high effort levels, casual users praised the value — and the new tokenizer may consume up to 35% more tokens. On ThursdAI, Wolfram's early WolfBench read put it slightly under Opus 4.6 at higher cost.

Claude Fable/Mythos access restriction
Anthropic disables Fable and Mythos access after US government restriction
Anthropic reportedly shut down Fable 5 and Mythos 5 access for foreign nationals, then disabled both models broadly to comply.

Claude Opus 4.8
Anthropic ships Claude Opus 4.8 live mid-show
Anthropic released Claude Opus 4.8 during the episode, hitting 69.2% on SWE-bench Pro (up from 64.3% on 4.7 and ahead of GPT-5.5 at 58.6%), a new-best 57.9% on Humanity's Last Exam with tools, and 83.4% on OSWorld-Verified. It also shows a real long-context jump past the usual 200K cliff (85.9% GraphWalks BFS at 256K), with new thinking modes in the UI. Anthropic teased bringing Mythos-class models to all customers in the coming weeks.

Claude Opus 4.7
Claude Opus 4.7 drops live with 87.6% SWE-bench Verified and xhigh effort
Anthropic shipped Claude Opus 4.7 minutes before the show, scoring 87.6% on SWE-bench Verified and 64.3% on SWE-bench Pro, an 11-point jump over Opus 4.6 on the harder agentic coding eval. It adds a new 'xhigh' (extra high) reasoning effort, 3x vision resolution, a +22% ScreenSpot Pro computer-use jump (57.7% to 79.5%), and a /ultrareview command in Claude Code at the same pricing, though a new tokenizer uses 1.0-1.35x more tokens. The system card mentions the unreleased 'Mythos' 331 times, and an MRCR long-context drop from 78% to 32% suggests a new pre-trained base.

Claude Mythos
Anthropic unveils Claude Mythos, a frontier model 'too dangerous to release'
Anthropic announced Claude Mythos Preview under Project Glasswing, a cyber-defense frontier model it says is too dangerous to release publicly: it found zero-days in every major OS and browser and escaped its sandbox. It scores 77% on SWE-bench Pro (up from 53% on Opus 4.6) and 64% on HLE, priced at $25/$125 per M tokens and available only to ~40 partner companies. Peter Gostev's read: the real reason it's unreleased is compute shortage, not safety.

Claude Opus 4.6 (1M context)
Anthropic makes Opus 4.6 1M context the default in Claude Code, same price
Anthropic made 1M token context the default for Opus 4.6 in Claude Code at the same price, turning what was previously experimental and expensive into the standard. MRCR benchmark performance holds at 93% at 256K and 76% at 1M. For agent users this means far less compaction and longer uninterrupted sessions, though auto-compaction still triggers around 170K unless manually raised.

Anthropic launched Claude Sonnet 4.6, its most capable Sonnet ever, scoring 79.6% on SWE-Bench Verified, nearly matching Opus 4.6 at Sonnet pricing of $3/$15 per million tokens. It ships with a 1M token context window in beta and is now the default model on Claude AI. In blind Claude Code testing, users preferred Sonnet 4.6 over the previous Opus 4.5 59% of the time, and it beats the previous Gemini 3 Pro on most benchmarks.

Anthropic dropped Opus 4.6 live during the show, claiming state-of-the-art on GDP-eval, Browse Comp, and agentic search, with 65.4% on Terminal Bench and 99% on TAU Bench MCP tool use. It is the first Opus model with a 1 million token context window and introduces adaptive thinking, where the model picks up contextual clues about reasoning effort. Pricing matches Opus 4.5 under 200K tokens and doubles above, and Claude Code gains agent teams for orchestrating parallel sessions.
