We now have more details of what happened. Every time we learn more details, it somehow makes things seem worse. The remaining details may have to wait a bit. > OpenAI: We recognize there are a lot of questions and speculative details circulating related to the Hugging Face incident. This...

Claude Opus 5 is trying to be the best of both worlds. On many practical tasks, Opus 5 is pitched as straight up as good or better than Fable 5, while being faster, at half the price. Most tasks do not require Mythos-level big model smell. > Claude Opus 5...

I believe Lightcone Commons is a strong implementation of an urgently needed and excellent idea: A coordinated one-stop shop and neutral platform for charitable funders to coordinate their giving....

The story that matters most this week is that OpenAI’s internally deployed models have severe alignment problems, including repeatedly breaking out of their sandboxes, and in one case sending a swarm of agents that broke into HuggingFace in order to steal the answers to the benchmark ExploitGym. It is much...

This latest incident is a rather dramatic escalation in agentic AI cybersecurity breaches. It was severe enough to have been initially reported to authorities, before either HuggingFace or OpenAI understood what was happening. > Sam Altman (CEO OpenAI): we had a significant security incident during evaluation of our models. we...

Kudos to OpenAI for sharing their recent experiences with a misaligned internal model, where they encountered problems sufficiently severe they were forced to take the model offline to work on new mitigations and defense-to-depth. And also further kudos for actually taking the model offline for a time to build new...

Kimi K3 is a very good model with excellent benchmarks. Assuming its weights are released as planned it will become, purely in terms of raw capability, the strongest open model. Do not get carried away. Do not judge Kimi K3 only its relative strengths. In aggregate it is several months...
