Unify

Unify is an LLM routing and model gateway platform that enables developers to access 100+ large language model providers through a single unified REST API and API key. The platform dynamically routes each prompt to the optimal model based on user-defined preferences across quality, speed, and cost dimensions, using live runtime benchmarks updated continuously across providers including OpenAI, Anthropic, Mistral, Together AI, Replicate, Groq, DeepSeek, and many more. Unify provides an observability dashboard for comparing model and provider performance, automatic fallback routing, and caching capabilities to reduce redundant API calls. Developers can benchmark models on their own prompts using standardized datasets and switch providers without rewriting application code using the unified model@provider endpoint syntax.

Unify publishes 8 APIs on the APIs.io network, including Agent API, Assistants API, Contexts API, and 5 more. Tagged areas include LLM, AI, Large Language Models, LLM Routing, and Model Gateway.

The Unify catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Unify’s developer surface includes authentication, documentation, engineering blog, pricing, and 15 more developer resources.
