The service drops in front of OpenAI or Anthropic SDKs, supports Claude Code and Cursor, and offers features like caching, per-team budgets, and session governance.", "body_md": "# Route every call to the cheapest model that holds quality.\n\nIQ Routing drops in front of chatbots, RAG pipelines, agent loops, and finance workloads. Cut spend 40 to 80 percent, measured on our own traffic, live in thirty seconds.\n\nCard required. No charge on Free.\n\nDrop in front of the OpenAI or Anthropic SDK you already use\n\nAny OpenAI- or Anthropic-shaped endpoint drops in behind one base URL. Kimi and GLM are next on the roadmap.\n\nThe problem\n\n## Every call hits your top model. The bill keeps climbing and nobody can say why.\n\nPin one frontier model on classification, retrieval, tool calls, and cleanup alike and you pay reasoning rates for work a cheap model would nail. Then the invoice lands as one line, shipping outruns anything finance can categorise, the cost report is a guess, and the audit trail is a Slack thread.\n\nOne worked example, before and after\n\n### The same five-step LangChain loop, routed two ways.\n\nThe Before trace pins every step on the same top-tier reasoning model, which totals $1.84. The After trace lets the resolver pick the cheapest variant that holds the quality bar on each step, which totals $0.77, or 58 percent less for the same five steps. Every per-step price is on the page, so the arithmetic is yours to check rather than ours to assert, and nothing in the agent code changes.\n\nBefore · vanilla LangChain\n\none provider, one budget#### Every step on claude-opus-4-8 at thinking=high\n\n- Planningclaude-opus-4-8 · thinking=high$0.42\n- Retrievalclaude-opus-4-8 · thinking=high$0.38\n- Tool callclaude-opus-4-8 · thinking=high$0.28\n- Synthesisclaude-opus-4-8 · thinking=high$0.41\n- Verificationclaude-opus-4-8 · thinking=high$0.35\n\nAfter · IQ Routing\n\nper-step resolver, session envelope#### The resolver picks the cheapest variant per step\n\n- Planningcap:reason-heavy · gpt-5.6-terra high$0.25\n- Retrievalcap:long-context-128k · gpt-4o$0.06\n- Tool callcap:tool-call-strict · gpt-4o no thinking$0.04\n- Synthesiscap:reason-heavy · claude-opus-4-8 high$0.41\n- Verificationcap:cheap-fast · gpt-4o-mini$0.01\n\nThe fix\n\n## One gateway. Six superpowers.\n\nEach one shows up on the dashboard the moment your first request lands.\n\n[State](/docs/api-reference)\n\n### Works inside the apps that lock models.\n\nSome tools only allow one model family. Point Claude Code, Cursor, or your own app at IQ and it stays inside the family they require, routing to the right tier for each step and never leaking to another vendor. It holds the conversation too, so switching models mid-thread stays safe.\n\nRead the docs →\n\n[Cache](/docs/caching)\n\n### Repeats resolve before they bill.\n\nWhen a request matches one IQ has already handled, the answer comes straight back and you are not charged for it again. IQ catches exact repeats and the ones that just mean the same thing, and every team's cache stays walled off from the rest.\n\nRead the docs →\n\n[Route](/docs/routing)\n\n### The router is the hard part.\n\nRouting well is the whole product. A purpose-built classifier reads each request for true difficulty, weighs it against live cost and latency across providers, and picks the model that clears your quality bar for the least spend, with instant fallback if one slips. It holds quality where a naive cheapest-model router quietly drops it.\n\nRead the docs →\n\n[Book](/docs/billing)\n\n### Every dollar has an owner.\n\nPer-team budgets, per-key limits, and a four-way input, output, cached, and thinking cost split, written to the ledger and enforced before the provider call.\n\nRead the docs →\n\n[Session](/docs/sessions)\n\n### A session is one accountable unit.\n\nEvery multi-step agent loop tracks per-turn cost, latency, tokens, and step class, and a governor caps how much thinking the session can spend.\n\nRead the docs →\n\n[Step](/docs/step-classifier)\n\n### Each step gets the right model.\n\nAn agent runs many steps, and most of them don't need your most expensive model. IQ sizes up each one and routes it to the cheapest model that can still do it well, so you get frontier quality where it counts and pay a fraction everywhere else.\n\nRead the docs →\n\n## What the dashboard looks like\n\nSpend, budgets, and per-team usage on one page.\n\nIllustrative dashboard, sample data.\n\nPricing\n\n## Priced so it pays for itself.\n\nStart free in thirty seconds.
