OpenAdapter

OpenAdapter is an API and chat interface for developers to run open-source language models from multiple labs (GLM, Kimi, DeepSeek, Qwen, MiniMax and others) on a single subscription. You get access to 101 models across four tiers, from free community models to top-tier flagships, plus web search, image understanding and vector storage. Use it through the browser chat, call the API from your app, or invoke Koda, the built-in coding agent, from Claude Code or your terminal.

Each request costs request credits based on model weight: standard models cost 1 credit, light models 0.5 to 0.75, flagships 2 to 3, and top tier 5. Your credits refill on rolling five-hour, weekly and monthly windows, so a busy afternoon doesn't consume your entire week's allowance. The free plan gives 50 requests per day with no card required.

You can keep your existing Claude subscription and use OpenAdapter's API alongside it, or hand tasks to Koda from inside Claude Code. You can also bring your own API keys from OpenAI, Anthropic and other providers and use them through OpenAdapter's dashboard.
