Smart Router Coding

Route coding queries to the right model. Fast for lint, deep for architecture, never waste money on Opus for a one-liner.

Route coding queries to the right model. Fast for lint. Deep for architecture. Nothing in between.

How it works

Send a coding task. The router decides depth:

INPUT: coding query
  ↓
Is it cached? → Return instantly (0 cost)
  ↓ if no
What kind of task?

SIMPLE
  lint / format / boilerplate / regex
  one-liners / find & replace / rename
  → Qwen3.5 Flash ($0.0008/q)
  → 21s latency

MODERATE
  debug / refactor / implement function
  code review / write tests / SQL / scripts
  → Grok 4.20 ($0.004/q)
  → 11s latency

COMPLEX
  architecture design / security audit
  performance optimization / algorithms
  multi-file changes / critical logic
  → Opus 4.8 ($0.015/q)
  → 45s latency

What you save

Setup	Cost per query	Monthly (1k queries)
All Opus 4.8	$0.015	$15
All Grok 4.20	$0.004	$4
With router	~$0.003	$3

Speed

Router adds 2ms. The rest is the LLM — you'd wait that long anyway.

What changes is your average response time:

Setup	Average wait per query
All Opus 4.8	45s
All Grok 4.20	11s
With router	~13s

Simple tasks go to Qwen (21s). Standard goes to Grok (11s). Opus only when necessary (45s).
