Forge Reasoning API is a configurable step-based planning engine that uses a mixture of open and closed LLMs alongside Nous' own reasoning techniques. Users can select between different tiers of reasoning to answer complex math, code, and reasoning questions that modern LLMs typically struggle with. You can now use Hermes, Claude, Gemini, and OpenAI models together to collaborate on difficult questions, super-charging them with advanced reasoning through our API. The entire reasoning trace is available via the API, offering total transparency and valuable data on the reasoning process.
