I co-wrote this RL environment FAQ with @datagenproc from @EpochAIResearch:
Frontier labs are investing massively in RL environments, yet most of what happens in this space stays behind closed doors. @chrisbarber and @js_denain interviewed 18 people from RL environment startups, neolabs, and frontier labs. Here's what they found:

Over the past 2 weeks, we’ve onboarded a few thousand businesses and developers from our waitlist per capacity to try Ultramarine 1 Flash. We were thrilled to see the variety of use cases and grateful for rich feedback to support future generations of the model. We’re excited to share that we’re releasing the weights and launching the model with early partners, including @FireworksAI_HQ and @baseten, to broaden access.

Introducing Real World Engineering Bench (RWE-Bench). AI isn’t great at designing rockets, engines, or chips yet. With better evals and RL environments, it will be. Software was just the beginning. The physical world is next.

I'm excited to launch Relational Capital, a $50m solo GP fund. I spent the last 8 years as a founder, building @usekojo into the largest US construction procurement platform. Now I'm backing founders at the earliest stages with $1m-$5m checks. An abundant future lies ahead 🇺🇸

We are releasing Ultramarine 1 Flash, a frontier-class model built for knowledge work. It is open-source and achieves similar performance to Fable 5, while being 60x cheaper. It was post-trained by a team of 5 for ~$300k all-in. Available on API now, with weights releasing in 2 weeks.
