NadirRouter / NadirClaw
Source-available LLM router and AI cost optimizer. Routes simple prompts to cheap or local models and complex ones to premium models, automatically. Drop-in OpenAI-compatible proxy for Claude Code, Codex, Cursor and OpenClaw. Self-hosted, no middleman.

What it does
- Context Optimize. compacts bloated context (JSON, tool schemas, chat history, whitespace) before dispatch, cutting 29-71% of input tokens on five synthetic payloads and 1-10% on real conversational traffic (benchmark). Every mode except of
- Smart routing. classifies prompts in ~10ms using sentence embeddings
- Pluggable classifier. binary (default, ~10ms centroid classifier) or distilbert (3-class fine-tuned DistilBERT that natively predicts simple/mid/complex). Select with NADIRCLAW_COMPLEXITY_ANALYZER
- Three-tier routing. simple / mid / complex tiers with configurable score thresholds (NADIRCLAW_TIER_THRESHOLDS); set NADIRCLAW_MID_MODEL for a cost-effective middle tier
- N-tier YAML config. one classifier head, any number of tiers. The default profile (n2_default.yaml) ships a cheap-and-strong two-tier cascade tuned on RouterArena (arena_F 0.7358, beats the legacy three-tier baseline). Switch profiles with
