Reka API Documentation

The Reka API serves Reka models and a curated selection of open models, including DeepSeek, GLM, Qwen and Gemma, through one OpenAI-compatible endpoint. You choose the model for each request, and Reka runs it on infrastructure it operates, from the API to the GPUs.

Point your existing OpenAI client at https://api.reka.ai/v1, use your Reka API key, and pick a model from the model list.
