Overmind turns anyone into an AI lab.
• Builds a context graph from code and traces
• Curates training and eval datasets
• Evaluates prompts and models
• Trains smaller, specialized models

Overmind's eye sees all at @NVIDIAGTC
The vision in Europe is clear. The future belongs to companies that build their own intelligence.
Overmind brings vision and future into alignment.
Stay tuned.
in berlin this week for #nvidiagtc, representing @OvermindLab. the last few years were about building the biggest engine, and the next few will be won by the pit crew. come say hi if you are building agents 🙌

I used to wonder why there has been rising interest in "open weight models" across the realms... 🌎
Then I realised the @OvermindLab eye sees all.
holy shit who is building this?
great segment on @theallinpod @DavidSacks @chamath @Jason
@OvermindLab is by far the easiest way to customise small models on your own proprietary data. direct from your coding agent, no in-house research lab required!
If your traces live in Langfuse, leave them there.
Overmind imports them and trains a model on them.
Works from Claude Code, Cursor, Codex or OpenCode.
Get started: pip install overmind

Own your agent's decisions.
Decision models pick an answer instead of writing one. Think Jev, Clef or OpenAI's Decisions API.
Overmind trains your agent on those decisions. The weights are yours.
Select the runs worth learning from and each becomes a training row, so the decisions your agent already makes become the training set.
Turn your company into its own AI lab.

Coinbase built this for their employees.
Overmind ships it for everyone.
Run /overmind finetune in:
• Claude Code
• Cursor
• Codex
Open source, and the model is yours.
We were able to fine tune an open weight model (Qwen3.5-9B) on proprietary internal data at @coinbase, and it out performed frontier models, at much lower cost and speed, for a specialized task (fraud prevention in this case).
I think we'll see more of this pattern inside companies. The frontier models are amazing generalists. But increasingly you'll see specialist models out perform on more narrow tasks, either working on teams, or by themselves.
We're making it easy to fine tune models internally for our employees. We even have a skill for it in our internal harness that makes it easy to spin these up and start training them:
"/fine-tune-and-serve-llm I want to fine-tune Qwen for payments risk review. help me get started"
I imagine we'll have some backend services that could be replaced entirely by this new architecture.

Overmind’s first week as the open-source training platform for agents.
Train the model behind your agent. Own the weights.
Onwards.
Overmind tested 4,000+ contract questions:
• Base model: 80.4
• Frontier flagship: 82.0
• Base model trained on the task: 91.6
Task data moved accuracy, not model size.
some numbers from our own testing. contract clauses, 4,000+ questions across 100+ contracts. base model 80.4 F1, frontier flagship 82.0, the same base model trained on the task 91.6. quoting the clause word for word: frontier 8.5%, trained 59.6%. so model size wasn't what moved it, the task data was

Train the model behind your agent. Own the weights.
Onwards.
Point Overmind at your agent’s codebase. Production traces become a fine-tuned model, scored on evals generated from your code before you switch.
Self-host it or use the console.

Many more to come! 🧱 🌎
Full house at House of AI! 🔥
We kicked off TechWeek in San Francisco with Model Training Night, hosted by @OvermindLab, @daytonaio & Prima Labs.
An amazing night at a special venue for us - House of AI is where we hosted our very first AI Builders - Demo Night in San Francisco back in February 2025. Great to be back and see the community filling the room again.
Find our team at the @COLM_conf today and tomorrow, where we have a booth, and across multiple events throughout this incredible week.
See you around SF! 🚀

Everyone’s building on the same models. Time to turn your team into a frontier lab:
▸ Star the repo: github.com/overmind-core/ove…
▸ Run the cloud version: console.overmindlab.ai
▸ Read more: overmindlab.ai/research/when…
AGENT TESTING & EVALS
Overmind scores prompts and models with evals built from real tasks in your production data.
Compare results with your current model, inspect failures, and catch regressions before deployment.
MODEL TRAINING
Fine-tune an open model on your own data. Overmind handles training and deployment.
You own the weights, with the choice to host on Overmind or run it yourself.
Start free: console.overmindlab.ai
