Supported Models
Check availability, model IDs, endpoints and pricing for Claude, GPT, MiMo and image generation models.
Claude, GPT, MiMo and image generation models are now live. Below are the model IDs for Claude and GPT; the full availability is determined by the model catalog and what the API returns.
See Public Models and Pricing for quotes; logged-in users can go to Console · Models to look up models and view integration methods.
Model List
Section titled “Model List”The model in your request must match the IDs in the table exactly, including the date suffix.
| Model ID | Series | Notes |
|---|---|---|
claude-fable-5-1 | Fable 5.1 | |
claude-fable-5 | Fable 5 | |
claude-opus-5-5 | Opus 5.5 | |
claude-opus-5 | Opus 5 | |
claude-opus-4-8 | Opus 4.8 | |
claude-opus-4-7 | Opus 4.7 | |
claude-opus-4-6 | Opus 4.6 | |
claude-opus-4-5-20251101 | Opus 4.5 | Pinned version ID with date |
claude-sonnet-5-5 | Sonnet 5.5 | |
claude-sonnet-5 | Sonnet 5 | |
claude-sonnet-4-6 | Sonnet 4.6 | |
claude-sonnet-4-5-20250929 | Sonnet 4.5 | Pinned version ID with date |
claude-haiku-5-5 | Haiku 5.5 | |
claude-haiku-4-5-20251001 | Haiku 4.5 | Pinned version ID with date |
Unit prices for each model (input, output, cache read, cache write) are on the Pricing Page. Model capabilities, context length and release notes are governed by the Anthropic official model docs.
Both Endpoints Work
Section titled “Both Endpoints Work”All models in the table above can be called via the Anthropic native /v1/messages and the OpenAI-compatible /v1/chat/completions, with the same model ID format. For Claude-specific parameters such as caching, thinking and tool calls, use the native endpoint; see Base URL and Authentication.
OpenAI / GPT Models
Section titled “OpenAI / GPT Models”gpt-5.6-lunagpt-5.6-solgpt-5.6-terragpt-6-astra
GPT can be used with the OpenAI SDK and Codex CLI. Endpoints and billing for different models are governed by the Console model catalog.
MiMo Models
Section titled “MiMo Models”IDs, supported endpoints and billing units for MiMo text and voice models are on Models and Pricing. Text is billed per token and voice per the billing unit of the corresponding model; do not apply Claude’s caching and discount rules.
Query the Latest List via the API
Section titled “Query the Latest List via the API”Models are added or removed as official releases occur; the API response is authoritative:
curl https://1zheai.com/v1/models \ -H "Authorization: Bearer sk-你的Key"curl -s https://1zheai.com/api/pricing | jq -r '.data[].model_name'How to Choose
Section titled “How to Choose”If you are unsure which to pick, you can start with:
| Scenario | Recommendation |
|---|---|
| Everyday coding, primary use in Claude Code | claude-sonnet-5-5 |
| Complex refactoring, hard-to-debug issues | claude-opus-5-5 |
| Subtasks, summarization, classification and other light work | claude-haiku-5-5 |
For how to map the opus / sonnet / haiku tiers to specific models in Claude Code, see Claude Code Integration.
Error says the model doesn't exist?
First verify the ID spelling and date suffix, then use the /v1/models above to confirm that your API key can see this model. Custom model names from other providers (e.g. with added prefixes or suffixes) cannot be used here.
When a model does not exist or is currently unavailable, the gateway returns HTTP 404. In the Anthropic native response, error.type is not_found_error; in the OpenAI-compatible response, error.code is model_not_found.
First verify the ID and the key’s available model list; do not repeatedly retry the same wrong ID. A 503 is only returned when the model exists but there is temporarily no healthy upstream service; see Error Codes and Troubleshooting.
The model in the response differs from what I requested?
Under normal conditions, the response’s model is the ID you requested. If it does not match, send the request time and response to [email protected]; you can also follow Verify Model and Usage to run the checks.
Image Models and Endpoint Lookup
Section titled “Image Models and Endpoint Lookup”The public catalog listed gpt-image-1.5 and chatgpt-image-latest as of 2026-10-16. See Image Generation Integration for details; actual permissions and parameters are governed by your key and the model catalog.
For full API examples for models, both response formats and troubleshooting when the list is empty, see Query Available Models API.
