Prime Intellect

Prime Intellect is a San Francisco–based startup building an open and decentralized stack for developing and improving AI agents through reinforcement learning. The company combines a 50+ provider GPU compute marketplace (single-node and 1–256 GPU multi-node clusters across H100, H200, B200, and B300), a managed RL post-training service ("Lab") that fine-tunes Qwen3.5, Llama, NVIDIA Nemotron, and OpenAI gpt-oss base models against a 2,500+ environment library (the Environments Hub), secure remote Python sandboxes for agent code execution, OpenAI-compatible inference at api.pinference.ai with LoRA adapter deployments, and an evaluations service that runs against the same environments. Prime Intellect is also the publisher of INTELLECT-3 (100B+ MoE trained with RL), INTELLECT-2 (32B trained via distributed RL), and the SYNTHETIC-2 dataset of four million reasoning traces, and develops the open-source `verifiers` RL library and the `prime-rl` async RL training framework. Everything is exposed via a single bearer-token REST API at api.primeintellect.ai, a `prime` Python CLI/SDK (PyPI: `prime`, lightweight `prime-sandboxes`), and the OpenAI protocol on the inference plane.

Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.

Kin Score

API Evangelist profiles Prime Intellect the way a machine reads it — 39 machine-readable artifacts across 20 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Prime Intellect scores 62.5/100 (strong), with a separate agent-readiness read of 48/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Prime Intellect

Each block below is one kind of artifact we hold for Prime Intellect. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 20

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

Open Collections 6

Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

Open, tool-agnostic API collections (OpenAPI-derived and Bruno).

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.

Published pricing tiers and plan structures.

Rate Limits 1

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Documented rate limits and quota policies.

FinOps 1

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Cost, billing, and metering signals for API financial operations.

Semantic Vocabularies 1

JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

Security Posture 3

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
