Inception

Inception Labs builds diffusion-based large language models (dLLMs) branded Mercury. Unlike autoregressive models that emit tokens one at a time, Mercury generates many tokens in parallel through discrete diffusion, running 5-10x faster at roughly half the cost of comparable frontier models. The Inception API is OpenAI-compatible and exposes chat completions (Mercury 2, a reasoning dLLM with a 128K context, tool calling, and structured outputs), plus fill-in-the-middle and next-edit code completions (Mercury Edit 2) for IDE-style autocomplete. It ships official Python and TypeScript SDKs, a streaming/diffusion mode, and enterprise deployment via the Inception API, AWS Bedrock, and Azure AI Foundry. Backed by Amplify Partners.

Inception publishes 4 APIs on the APIs.io network, including Chat API, Edit API, FIM API, and 1 more. Tagged areas include Company, Ai Ml, LLM, Artificial Intelligence, and Diffusion Models.

Inception’s developer surface includes documentation, API reference, getting-started guide, authentication, engineering blog, support, pricing, and 26 more developer resources.
