GoModel is an open-source AI gateway written in Go that exposes a single OpenAI-compatible API while routing requests to OpenAI, Anthropic, Gemini, Groq, xAI, Azure OpenAI, Ollama, and more. The standout feature is its two-layer caching system: exact-match caching for verbatim repeated queries plus semantic vector caching for similar ones — meaning you stop paying twice for the same question phrased slightly differently. That alone can meaningfully cut API bills for production apps. Beyond routing, GoModel adds built-in Prometheus observability, an audit logging pipeline, content filtering guardrails, full streaming support, file management across providers, and batch job handling. It deploys via Docker Compose with PostgreSQL, MongoDB, or SQLite backends. Configuration is environment variable and YAML-based, making it CI-friendly from day one. The Go-native implementation is what sets this apart from incumbents like LiteLLM (Python). Lower memory footprint, higher concurrent request throughput, and single-binary deployment make it genuinely attractive for teams that care about infrastructure costs as much as API costs.

Reviewer scorecard
“This is what I've wanted since LiteLLM started feeling bloated. Go binary, semantic caching, Prometheus metrics out of the box — it's a proper infrastructure-grade gateway, not a weekend hack. Multi-provider fallback alone is worth the Docker setup time.”
“The most mature AI API with the largest ecosystem. Function calling, JSON mode, and assistants API cover every use case.”
“GoModel is entering a crowded space against LiteLLM, PortKey, and OpenRouter, all of which have months or years of production hardening. The semantic cache sounds great in theory but adds latency on misses and requires careful embedding model management. Wait for v1.0 and some battle scars before running this in prod.”
“Reliability has improved significantly. The ecosystem and tooling around OpenAI's API remain unmatched.”
“As model counts explode and companies run multi-provider strategies to hedge against outages and costs, a fast, open gateway becomes core infrastructure — not optional tooling. Go's concurrency model is genuinely the right choice here. This could become the nginx of LLM routing.”
“OpenAI set the standard for AI APIs. The Assistants API and real-time API point toward increasingly capable agent platforms.”
“Even for non-infra folks, the semantic cache means your AI-powered creative tools get dramatically cheaper at scale. Drop this in front of your image gen or copy gen pipeline and the cost curve bends fast. Love that it's MIT and self-hostable.”
