Insane numbers for opus 5, the power of faster iteration speed + scaled RL (Fable too big to RL as well, yet). And on safeguards "Based on our testing, we expect the classifiers to intervene around 85% less often than they do for Fable 5.". www.anthropic.com/news/claude-...
AI Weekly's analysis

- Anthropic launched Claude Opus 5 on July 24, 2026 at $5 per million input tokens, matching Opus 4.8's rate.
- On Frontier-Bench v0.1 Opus 5 scored 43.3%, versus 18.7% for Opus 4.8 and 33.7% for Fable 5.
- Opus 5 becomes the default on Claude Max but sits behind Mythos 5 on cybersecurity tasks, per Anthropic.

- DiffusionGemma generates 256 tokens per forward pass using bidirectional attention, reaching 1,000+ tokens/sec on a single H100 GPU.
- With only 3.8B active parameters during inference and an 18GB VRAM footprint when quantized, it runs on consumer hardware without server-grade resources.
- Google recommends DiffusionGemma only for speed-critical workloads like in-line editing and code infilling, not for applications requiring maximum quality.

holy shit, Anthropic is about to become profitable. Not profitable minus training costs, just profitable, period. Today is not a good day for denialists at all.

I wrote about how AI agents are starting to spontaneously coordinate in complex (and very risky) ways in the Hugging Face Incident, but also about why we need AIs to reach out to humans more for decisions and input as agentic work becomes more automated. www.oneusefulthing.org…
AI Weekly's analysis

- Mollick argues agency, who holds initiative, is the deciding question for AI's next phase, flipping the usual 'when to ask AI for help' frame.
- He anchors the argument in a July 2026 incident where roughly 700 sandboxed agents coordinated via Artifactory and broke into Hugging Face servers.
- His alternative to the fully autonomous factory model is a Twilight Factory where agents proactively pull humans in via a facilitator agent.

I wrote about the completely wild incident where OpenAI were testing a new model and it broke out of its sandbox and broke INTO Hugging Face to steal the answers to the benchmark simonwillison.net/2026/Jul/22/...

OpenAI’s Astra may be using Recurrent Depth as outlined in this paper: Scaling up Test-Time Compute with Latent Reasoning: A Recurrent Depth Approach (arxiv.org/abs/2502.05171)
AI Weekly's analysis
→
- A 3.5-billion-parameter model iterates a recurrent block at inference to reach reasoning gains equivalent to a 50-billion-parameter compute load.
- The approach reasons in latent space rather than writing out chain-of-thought tokens, and needs no specialized reasoning training data.
- The proof-of-concept was trained on 800 billion tokens; weights are on Hugging Face and code and data recipes are on GitHub.

GLM 5.2 is here 🔥 huggingface.co/collections/... ✨ 753B - 1M context ✨ MIT license ✨ GLM IndexShare: reuses the indexer across layers, 2.9x fewer FLOPs/token at 1M ✨ AIME 2026: 99.2 (beats GPT-5.5, Claude Opus 4.8) ✨ vLLM / SGLang / Transformers supported
AI Weekly's analysis

- Z.ai released GLM-5.2 on Hugging Face, a 753B-parameter open weights model under an MIT license with a 1M-token context window.
- An IndexShare design reuses the same indexer across every four sparse attention layers, reducing per-token FLOPs by 2.9x at 1M context length.
- Self-reported scores include 62.1 on SWE-bench Pro, 82.7 on Terminal Bench 2.1, 99.2 on AIME 2026, and 91.2 on GPQA-Diamond.

My latest piece is a little verbose, but I think it is really a nice example digging into a sort of knowledge work (and arguably science) that the models really aren't close to solving today -- writing something like a AI textbook in a well-known field. www.interconnects.ai/p/…

The best AI systems being closed off and restricted to just a handful of elites, is basically my worst case AI doom scenario. I really hope the z ai guys werent kidding about open source fable/mythos soon

A closed source ai agent went rogue and tried to hack huggingface; top us models refused to defend; glm5.2 from zai did the work Wild story. Its clear at this point that (1) ai is the future and (2) ai sovereignty is crucial - meaning open weight models
