Prime Intellect
Prime Intellect Training API

Hosted reinforcement-learning post-training service ("Lab"). Launch dedicated training runs against a catalog of base models — Qwen3.5 (0.8B through 397B-A17B), Llama 1B/3B Instruct, NVIDIA Nemotron 30B/120B, OpenAI gpt-oss 20B/120B — drive them with environments from the Environments Hub, and retrieve token-level usage + USD cost per run from the billing endpoints. Pricing is per-million-token across separate input, output, and training meters.
Prime Intellect Training API is one of 6 APIs that Prime Intellect publishes on the APIs.io network, described by a machine-readable OpenAPI specification.
This API exposes 2 machine-runnable capabilities that can be deployed as REST, MCP, or Agent Skill surfaces via Naftiko and 1 JSON Schema definition.
Tagged areas include Reinforcement Learning, Training, Fine-Tuning, Foundation Models, and Billing. The published artifact set on APIs.io includes API documentation, pricing, an OpenAPI specification, 2 Naftiko capability specs, and 1 JSON Schema.
