AI21 Labs offers Post-Training
Service
AI21 post-training helps enterprises build specialized models trained on their proprietary data.
- Currently Offered
AI21 works with enterprise teams to post-train dedicated models for their tasks, using their data to target quality, latency, and cost requirements. The engagement produces a production model and provides the team with a training recipe for future runs.
Forward-deployed researchers work alongside customer teams to build specialized models and develop in-house training capability. The service centers on models tailored to business data and tasks rather than general-purpose rented AI.
