    Happy to finally make this announcement of our Seed and Series A raises. It's been a great journey since I left Google DeepMind 2.5 years ago with a goal to democratize post-training! Post-training gets easier if you have access to good data and now, RL environments. That's why

    We’re thrilled to announce a $40M investment that will fuel our mission to make AI agents reliable. For the past two years, we've been heads-down doing world-class data curation research and shipping best-in-class reinforcement learning environments for training and optimizing

    We should all walk around thinking about verifiers (and maybe at other times none of these).

    I used to walk around thinking about code. I could "see" the code in my head. It was pretty cool. If there was a bug I could often click straight into a specific file and fix it with no other context, like a type of muscle memory. Now I think in prompts. I'll be cooking dinner

    We created data-eng-bench with @bespokelabsai and we’re open-sourcing it. There are plenty of model performance benchmarks for code generation. But for data engineering, the harness matters just as much as the model. We built a benchmark that asks agents to build and fix
