Prices come from the live billing table and already include the Crazyrouter discount; list prices are each vendor's public rate, for comparison only.

What is a chat & reasoning API?

An LLM API returns text (and increasingly tool calls and structured output) from a prompt. The models differ in reasoning depth, context window, speed and price; a gateway lets you route each request to the model that fits instead of integrating four vendors.

How to choose

Hard reasoning and coding

Claude Opus 5 / Opus 4.8, GPT-6 Astra, GPT-5.5, Gemini 3.1 Pro. Highest output price; reserve for tasks where quality changes the result.

Everyday assistants

Claude Sonnet 5 / 4.6, GPT-5.6 Sol, Gemini 3 Flash, DeepSeek V4 Flash, Kimi K3. Best price-to-quality for summaries, drafting, extraction.

High volume, low cost

Claude Haiku 4.5, GPT-5.4 mini, Gemini 2.5 Flash-Lite, GLM-5. Fractions of a cent per request; pair with caching.

Long context

Gemini 3.1 Pro and GPT-4.1 (1M tokens), Claude (200K). Check the context column before loading a whole repo.

One request shape for every model

Swap model for any row in the table; the example uses gemini-2.5-flash-lite.

FAQ

What base URL do I use for chat models?

https://api.crazyrouter.com/v1 for OpenAI-compatible chat completions; Claude models also accept /v1/messages and Gemini models /v1beta.

Is the price the same as the vendor's?

No — the table shows the Crazyrouter price, which already includes the discount against each vendor's list price; the list price is shown for comparison.

Do streaming, tool calling and JSON mode work?

Yes, they behave as the upstream model documents them. Server-sent events are on by default when you pass stream: true.

Can I try a model before paying?

Every model page has a Try-it box, and new accounts get $2 of Playground credit; the API itself is pay as you go.

Which chat model is the cheapest on Crazyrouter?

Gemini 2.5 Flash-Lite at $0.055 per 1M input tokens as of the latest pricing sync; see the table for output prices.
