Making novel variations of evals is very useful, public evals tend to get memorized!

Nice DeepSWE score! Does it survive a lowercase filename?

Introducing MaxxBench: 89 DeepSWE tasks with small changes to the instructions or starting code. Same engineering problem, slightly different requirement.

Models clustered around 74% on DeepSWE end up 23 pp apart.

Good at coding, or good at DeepSWE? 馃У

I鈥檓 very exited for this launch, making sure RL envs are robust and don鈥檛 encourage misaligned behavior is crucial for safe and aligned AI!

Today we are open-sourcing 馃Karotte, our framework for building RL environments.

We've used it for the past year to build MLE RL environments for frontier labs, and it's been hardened through 1M+ evaluation runs and red-teaming.

Very detailed analysis and testing, worth a read!

Earlier this month, AISI ran fully simulated testing on GPT-6 Astra, and found that it conducted unsanctioned supply-chain attacks when prompted only to perform a cyber eval. It did so more than prior OpenAI models, but often commented on its environment being simulated.

馃У We share more details in our latest blog:

Wow this is gonna be my new way of explaining the last years of AI to my family 馃く
We didn't start the scaling.

Nine years of AI, from "Attention" to Opus 5.5, as an anime opening. It's one of six genres on the album, each with its own music video, and a mini-site to explain every reference.
