API Platform

Menlo is building an API Platform for developers:

• Developer APIs for Menlo’s models and popular LLMs
• Realtime API with vision and audio
• Fine-tune and deploy your own models
• Tool APIs (e.g. Deep Research, Browser Use, and other MCP servers)
• Open-source and self-hostable

Menlo’s API Platform is designed to be a 1:1 drop-in replacement for OpenAI’s API Platform, that can be used as a cloud service or self-hosted.

Menlo’s API Platform will also power Jan’s free Research APIs, which will be available in Q3 2025.
