## TL;DR

Hey HN, We just open-sourced Styx — an AI gateway that sits between your app and AI providers (OpenAI, Anthropic, Google, Mistral).

---

## Summary

Hey HN, We just open-sourced Styx — an AI gateway that sits between your app and AI providers (OpenAI, Anthropic, Google, Mistral). One endpoint, any model, self-hosted. What makes it different from LiteLLM or OpenRouter: styx:auto — send "model": "styx:auto" and the gateway picks the right model based on prompt complexity. Simple questions go to cheap models ($0.15/1M tokens), complex code goes to frontier models. 9-signal classifier, zero config. MCP-native — first gateway with a built-in MCP server. Connect Claude Code or Cursor in one command: claude mcp add styx -- npx styx-mcp 65+ models with live pricing — prices auto-refresh every 24h from OpenRouter's public API. Self-hosted in 5 min — git clone, run setup.sh (interactive wizard), docker compose up. Tech stack: Go (router/proxy, https://github.com/timmx7/styx Would love feedback on the architecture and the auto-routing approach.

## Nauti's Take

Styx plays the API-aggregation game everyone's already playing — but the 9-signal complexity classifier for auto-routing is a genuinely smart twist. Routing cheap prompts to cheap models automatically could save teams real money without any prompt engineering overhead.
