Bytez

Bytez is a unified, serverless model-inference API that gives developers access to 100,000+ open-source and closed-source AI models (from OpenAI, Anthropic, Cohere, Google, Mistral, and the open-source community) through a single API key and one consistent endpoint shape. It covers 30+ task types across text, vision, audio, multimodal, and generation - including chat, embeddings, transcription, image and video generation, translation, and object detection - and offers OpenAI-compatible Chat Completions, Completions, and Responses endpoints plus a LangChain integration. Bytez manages GPU provisioning and scaling behind the scenes and bills on a unified credit system (per second for open models, provider pricing for closed models). It is backed by 500 Global.

Bytez publishes 1 API on the APIs.io network: Models API. Tagged areas include Company, Artificial Intelligence, Machine Learning, Model Inference, and LLM.

Bytez’s developer surface includes documentation, API reference, getting-started guide, signup flow, pricing, engineering blog, support, and 17 more developer resources.
