Model Factory is where you build your own models on Prime Intellect. You train a model, evaluate it, deploy it, and use what it does in production to train the next version. Each step runs on the same platform, so a checkpoint from one step is ready for the next. Model Factory is built on our open-source libraries: prime-rl for training and verifiers for environments and evaluations.

​
The loop

​
Two ways to run it

To run the same training framework on your own hardware, use prime-rl directly.

​
Train

Hosted Training supports three kinds of run. Each one is dispatched with prime train and a TOML config.

Reinforcement learning

Full-parameter RL against a verifiers environment.

Supervised fine-tuning

Train on examples of the behavior you want.

Pretraining

Pretrain a model from scratch on your own corpus.
Run prime train models to see which models start warm and what each GPU type costs. See Models for details, and Volumes for how checkpoints are stored.

​
Evaluate

Run an environment against a model from the dashboard or with prime eval run --hosted. Results appear on the Evaluations page. See Evaluating environments for the local and hosted workflows.

​
Deploy

Create a dedicated inference endpoint from the Dedicated Endpoints page. An endpoint serves a model through an OpenAI-compatible API on GPUs reserved for it. For shared, pay-per-token models, see Prime Inference.

​
Improve

Prime Traces stores the traces from your training runs, evaluations and endpoints. Use them to see what the model did on each task and where it failed. A recurring failure can become an evaluation or a training task in your next run. Trace uploads incur ingestion and storage charges. See Pricing and settings.
