LAB-AS-A-SERVICE MODEL TRAINING
Your partner on the journey to specialized intelligence
Our Forward-Deployed Researchers [FDRs] train specialized models for your task, creating an AI edge your competitors can’t buy.

Renting got you started.
Owning gets you ahead.

Rented AI
Available to everyone, a rented model only improves when its provider ships an update. Anything you’ve tuned on top has to be rebuilt.

Owned AI
Trained on data that’s uniquely yours, your model keeps learning from your production traffic. That’s compounding value you own.
Your edge is already in your data. We turn it into intelligence.
When every company builds on the same rented model, AI stops being an edge and starts becoming table stakes. Your edge lives in your proprietary data, your workflows and your domain judgment. A model trained on it is the one AI asset that’s uniquely yours.


Model and harness, trained together for maximum lift.
Training the model or the harness on its own only gets you so far. We train both together. Our harness optimizer finds the best configuration for your agent, so it ships production-ready at the cost-quality operating point you choose.
Platform
Building your evaluation suite
We define together what ‘better’ means for your model, build evals from your real tasks, and gate quality, cost and latency throughout. At the end of the engagement, the evaluation suite stays with you.

Creating the best recipe for your task
Drawing on 5 years of experience with a wide range of on- and off-policy training methods, our FDRs develop the right hill-climbing approach to jointly tune your harness and model for your specific task.

Optimizing your model for production
After training completes, the FDR team optimizes the model and harness for fast and efficient serving, managed either by AI21 or deployed directly in your environment.

Compounding quality over time
Your first model ships in weeks. From there, your team can lead each new training run with the recipe and evaluation suite our FDRs leave behind, so your model keeps improving on fresh production traces over time.
