Best LLM routers and model routing platforms in

LLM model routing serves as the operational layer in AI systems that determines which model or provider processes each request, with its effectiveness varying based on whether it prioritizes resilience, cost control, or quality-based model selection. Different platforms offer various focuses: some emphasize resilience through backup systems and provider ordering, others prioritize cost-efficiency by routing simpler requests to cheaper models, and the most robust setups link routing decisions to actual performance data from live traffic. Braintrust stands out as a leading platform for teams that desire model selection informed by evaluation, online scoring, and real-time traffic experiments within a cohesive workflow. It provides a unified API for accessing models from major providers like OpenAI, Anthropic, and Google, supporting both custom and self-hosted models while offering tools for caching, credential management, and routing observability. Other notable platforms such as OpenRouter, Vercel AI Gateway, Portkey, and LiteLLM offer varying strengths, from broad model access and managed provider routing to open-source, self-hosted solutions, each catering to specific operational needs and priorities.
