We evaluated an early version of Claude Mythos Preview for risk assessment during a limited window in March 2026. We estimated a 50%-time-horizon of at least 16hrs (95% CI 8.5hrs to 55hrs) on our task suite, at the upper end of what we can measure without new tasks.

@HaifeiLi imo, LLMs doesn’t care if it’s assembly, the clock is ticking, going to be fascinating!

Current sci-fi timeline: Models learn to hide reasoning in RL. Safety observed this. OpenAI publishes. Next training ongoing (sees this).

And…we’re still early!

[Micah Carroll @MicahCarroll]

We recently found some instances of CoT grading during the training of previously deployed models after building a system that scans all OpenAI RL runs for accidental CoT grading.

We did not find clear evidence that these instances degraded CoT monitorability.

@moyix There has to be a movie about this!

@XorNinja The fascinating part is we are still early…!
