Sail Research

Sail Research provides infrastructure for long-horizon agents: cost-efficient inference for leading open-source models (GLM, DeepSeek, Kimi, Nemotron and others) run on demand. Its API is OpenAI- and Anthropic-compatible (Chat Completions, Responses, Messages, Batches), so existing clients migrate by changing the base URL and key. Completion windows (asap/priority/standard/flex) trade latency for lower per-token price for background and agentic workloads, and Sailboxes provide full persistent VMs for long-running agents. Sail raised $80M and is backed by Kleiner Perkins. This profile was enriched by the API Evangelist pipeline from Sail's public OpenAPI, docs, SDKs, CLI, and MCP surface.

Sail Research publishes 5 APIs on the APIs.io network, including Batches API API, Chat Completions API API, Messages API API, and 2 more. Tagged areas include Company, Artificial Intelligence, LLM, Inference, and Agents.

The Sail Research catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Sail Research’s developer surface includes documentation, API reference, getting-started guide, pricing, signup flow, engineering blog, authentication, and 22 more developer resources.
