Excited to share Aryabhatta 1.0, our leading model that scores 90.2% on JEE Mains, outperforming frontier models like o4 mini and Gemini Flash 2.5 Trained by us at @AthenaAgentRL , in collaboration with @physics__wallah, using custom RLVR training on 130K+ curated JEE problems 7B parameters and 4K context is all you need to crack JEE Also, you don’t need to blindly follow GRPO. Custom objective functions make a huge difference Details below 👇

@nrmehta @jaminball we are betting on the limits of that generalization for the long tail issues and building the infrastructure so that enterprises can own, adapt and deploy their models efficiently

Investor @jaminball's weekly newsletter is always a must-read for me - this one is particularly good. "Owning Your Weights" through an open source model does give a company a lot of autonomy. But it comes with a price of the effort of not just running an open source model but also putting the work into pipelines and evals to keep RLing it. Inference clouds help a lot but they don't take away the need for internal expertise. Right now, there aren't enough people in the world who know how to do this to allow everyone enterprise to "own their weights." The intermediate layer of infrastructure to make this task less onerous (as Jamin points out) could change the equation. The being said, one sobering (bitter 😂) question - if the frontier actually generalizes even more and gets more efficient, will a company's internal team be able to keep up in the long run? Such a foundational question (to which no one has the answer) for the long run.

We raised $130M @ $1B for our series A To build the open superintelligence stack for everyone Pre-training concentrated frontier AI in a handful of labs. RL changes who can build frontier AI and just works across almost any verifiable domain. We want to enable everyone to train their own agents. Companies can now own their model optimization loop: train directly on your product, optimize for your specific workflows, and build agents that improve continuously in production Owning this model <> product improvement loop is how you build a compounding moat in the agentic era Super grateful to serve over 6k+ customers, including many leading AI startups, neolabs and enterprises already building on our stack, and to our incredible team for shipping hardcore! We train open frontier models and ship the same stack to our customers. Its spans the full stack of training, deploying and continuously improving models — compute, large-scale RL, environments, sandboxes, evals, and deployment. We're excited to be joined by angels who are building the frontier themselves, many of whom we work closely with: @johnschulman2 (Thinking Machines), @dwarkesh_sp, @AravSrinivas (Perplexity), @karimatiyeh (Ramp), @levie (Box), @_milankovac_ (Tesla), @winstonweinberg (Harvey), @amspector100 (Flapping Airplanes), @jeffwang (Cognition), @_arohan_ (Core Automation), @marksaroufim (Core Automation), @mikeknoop (Zapier, Ndea), @eastdakota (Cloudflare), @BrendanFoody (Mercor), @devanshpandey (Standard Intelligence), @hwchase17 (Langchain), @nicoup (Fleet) and many more We're a small team building open superintelligence > Reach out if you want to partner training, deploying and continuously improving your own frontier models for your use case > Join us to build open superintelligence — we're hiring across all roles including RL, inference, distributed systems, full stack engineering and compute.

my latest blog post "auto-research with codex: how I achieved a 212x faster kernel over baseline with codex in GPU Mode's qr_v2 problem" is up now. in this post, i talk about my approach towards auto-kerneling on the QR decomposition problem. sankalp.bearblog.dev/autoresearch/

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 have poured our energy into doing data research. And we will continue to make Bespoke into one of the world's best data research labs. Thank you everyone for your support and thanks to the incredible Bespoke team that has done amazing work so far! PS1: Yes, we got busy with building after our Seed (MiniCheck, Curator, OpenThoughts, Terminal Bench..) so we didn't get a chance to announce the Seed raise! PS2: I will be at ICML starting Wed!
Bespoke Labs@bespokelabsai

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 AI agents. This funding lets us go a lot deeper on both. Thank you to our investors @Wing_VC, @MayfieldFund, @8vc, @thehousefund and our angels such as Jeff Dean, Dheeraj Pandey, Tristan Handy, and several others from Anthropic, OpenAI, Meta. And thanks to the frontier labs and enterprises we work with every day, for sharing our vision for a future where agents can run autonomously for weeks and months at a time. (more below)

We are looking for more amazing researchers and engineers to join our team. EquiLibre Technologies is a frontier AI trading research lab. We train our own foundational models, use our own RL algorithms, and trade our own money. The proof is in the pudding. [THREAD] equilibre.ai techcrunch.com/2026/06/30/the…
