Models
One catalog across every provider. Model IDs are stable strings you can hardcode.
The live catalog is the source of truth
GET /v1/models returns the CHAT models your account can call right now, including any added since this page was written. Speech and image models are not in that list — see List models.
By modality#
Text
Chat, reasoning, tool calling and vision input.
Speech
Text to speech, billed per character of input.
Image
Generation and editing through an asynchronous job API.
Model families#
Every family is reachable through both request formats. The vendor prefix identifies who made the model, not which provider serves it — xKiro may reach the same model through more than one route.
OpenAI
openai/…General-purpose reasoning and coding models. The default choice when you are not sure what to reach for.
Anthropic
anthropic/…Claude models, tuned for Anthropic's official clients — Claude Code, the Claude CLI and Anthropic's editor extensions.
Z.AI
z-ai/…GLM models. Strong coding performance with a switchable thinking mode.
MiniMax
minimax/…M-series models for agentic work, reachable through the Anthropic or OpenAI dialect.
DeepSeek
deepseek/…Reasoning-first models with strong mathematics and code generation.
Qwen
qwen/…Multilingual models with vision and video understanding.
Model IDs#
Every ID is vendor/model. Send the whole thing — the bare model name does not resolve.
{ "model": "openai/gpt-5.6-sol" } // correct
{ "model": "gpt-5.6-sol" } // 404 not_foundWhy the prefix is required
Two vendors can ship similarly named models. Resolving a bare name would mean guessing which one you meant, and guessing wrong bills you for a model you never asked for.
Choosing a model#
- Start mid-tier. Most tasks do not need a flagship, and the latency difference is larger than the quality difference.
- Move up only on evidence.Have a case the smaller model gets wrong before paying several times more per token. "It feels better" is not measurable.
- Classification, extraction and routing — the smallest model that passes your tests is almost always right.
- Check capabilities, not names. A model name does not reliably predict vision, tools or context window. See Capabilities.
A note on Anthropic models
Claude models are tuned for Anthropic's official clients, where they run on Anthropic infrastructure end to end. Other tools still work: those requests are automatically served by a comparable model of equivalent capability, billed at the price of the model you selected.
