# Multi-Provider

Multi-agent model API that orchestrates frontier models behind one OpenAI-compatible endpoint

Sakana Fugu is a hosted model-provider API that exposes a learned multi-agent system as one OpenAI-compatible model. It dynamically routes coding, code review, research, and reasoning tasks across a frontier-model pool, with Fugu for lower-latency work and Fugu Ultra for harder workloads where answer quality matters more than cost or speed.

Self-hosted proxy API for routing AI CLI accounts into OpenAI-compatible endpoints

CLIProxyAPI is an open-source Go proxy server that wraps Gemini CLI, Claude Code, OpenAI Codex, Grok Build, and related CLI account flows behind OpenAI/Gemini/Claude-compatible API endpoints. Use it carefully: it can touch OAuth sessions, auth files, logs, and provider account policies, so production use needs credential and ToS review.

Smart LLM router that cuts inference costs up to 70%

Manifest is an open-source smart model router that intelligently routes LLM requests to the cheapest capable model, reducing inference costs by up to 70% without sacrificing output quality. It uses a 23-dimension scoring algorithm to evaluate 300+ models across providers including OpenAI, Anthropic, Google, and DeepSeek, with automatic fallbacks and budget controls. Manifest can be deployed as a cloud service, local plugin, or self-hosted Docker container with transparent routing logic.
