# Lambda Inference API

**Canonical:** https://apis.io/apis/lambda-labs/inference-api/  
**Provider:** Lambda — https://apis.io/providers/lambda-labs/  
**Base URL:** https://api.lambda.ai/v1  
**Documentation:** https://docs.lambda.ai/public-cloud/lambda-inference-api/

Lambda Inference API is one of 13 APIs that [Lambda](https://apis.io/providers/lambda-labs/) publishes on the [APIs.io](https://apis.io/) network, described by an AsyncAPI event-driven specification. Tagged areas include Artificial Intelligence, Chat, Completions, Inference, and LLM. The published artifact set on APIs.io includes API documentation and an AsyncAPI specification.

Lambda Inference API is an OpenAI-compatible REST gateway at https://api.lambda.ai/v1 that serves hosted open-source language models (Llama, DeepSeek, Hermes, Qwen, and others) behind the standard OpenAI Chat Completions surface. Chat completion responses can be streamed as HTTP Server-Sent Events by setting "stream":true on the POST /chat/completions request body; the SSE stream emits chat.completion.chunk events terminated by a data [DONE] sentinel. As of 2026-05-29 Lambda has announced the Inference API is winding down in favor of customer self-hosted deployments on Lambda GPU instances.
