The global neuronal workspace (GNW) is currently the best documented neuroscience mechanism by which conscious processing arises in the human brain — and now Anthropic researchers have discovered a similar workspace inside their large language model ! www.anthropic.com/researc…

  • Anthropic says Claude has a 'J-space' of dozens of concepts, under a tenth of neural activity, that mediates multi-step reasoning.
  • Swapping 'spider' for 'ant' inside the J-space changed Claude's leg-count answer from 8 to 6, demonstrating a causal role.
  • A 'J-lens' tool surfaced silent words like 'fake', 'fictional' and 'manipulation' during deception tests, pointing at safety uses.

And this is an open-weights model, which means that anyone can download this model and run it. (You'll need a high end consumer device or use an inference provider) Download the model from here: huggingface.co/zai-org/GLM-...

WSJ: Chinese AI systems have matched the performance of Anthropic’s powerful model Mythos in some cybersecurity scenarios, a development poised to reset the global tech race – ‘China’s advances coincide with unprecedented U.S. government roadblocks to developers releasing mode…

Re-upping this piece on 'distillation attacks' from Feb as I believe this plays a role in the reason for the US to block non-US users of Fable. In a distillation attack other labs (e.g. Chinese) try to retrieve (distill) information from an LLM. www.anthropic.com/news/detecti...

It's on you to get your friends and colleagues off of twitter. Pass it along.

Simple contagion drives population-scale platform migration arxiv.org
AI Weekly's analysis →
  • Researchers linked 276,431 Twitter/X scholars to their profiles among 16.7 million Bluesky accounts, tracked January 2023 through December 2024.
  • Brazil's court-ordered suspension of Twitter/X served as the natural experiment, with treatment effects on migration that were short-lived and dose-dependent.
  • Adoption was driven by simple contagion rather than complex contagion, with early reconnection to prior contacts predicting longer tenure on Bluesky.

Self-Harness: Harnesses That Improve Themselves arxiv.org
AI Weekly's analysis →
  • Self-Harness has an LLM agent edit its own harness through a three-stage loop of failure mining, harness proposal, and regression testing.
  • On Terminal-Bench-2.0, MiniMax M2.5 rose from 40.5% to 61.9%, Qwen3.5-35B-A3B from 23.8% to 38.1%, and GLM-5 from 42.9% to 57.1%.
  • The authors report edits are model-specific and minimal, targeting distinct failure modes rather than adding generic instructions.

There are four ways of running an #AI model. They all have pro's and cons. And with the weekly arrival of new models, changes in pricing & policies and the rise of agents this is a field to watch.

My student, who wrote his thesis with AI about AI while doing an internship at an AI consultancy, failed at writing his BSc thesis. In a strange way very satisficing. Even with unlimited tokens you’ll need to keep thinking.

After programming all morning with Claude Fable 5 I asked Claude if I always need Fable. He came up with an *honest* answer... Anthropic should make a feature that chooses the most fitting model based on the prompt.
