Reka is the model family — including Reka Flash and Reka Core — built by Reka AI, a small independent lab founded by former DeepMind, Google Brain, and Meta AI researchers. It sits at #17, the least-used model in this ranking at roughly 0.4% usage share, reflecting its status as a much smaller player next to the big labs. Reka is best known for building genuinely multimodal models (text, image, video, and audio input) that hit competitive benchmark scores despite the company's small size and lower compute budget compared to Google, OpenAI, or Anthropic.
Reka's API is OpenAI-compatible and can be called with a plain curl request or the requests library against its chat completions endpoint.
