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](https://1zheai.com/en/pricing/) for quotes; logged-in users can go to [Console · Models](https://1zheai.com/model-catalog?lng=en) to look up models and view integration methods.

## 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](https://1zheai.com/en/pricing/). Model capabilities, context length and release notes are governed by the [Anthropic official model docs](https://platform.claude.com/docs/en/about-claude/models/overview).

## 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](/en/docs/base-url/).

## OpenAI / GPT Models

- `gpt-5.6-luna`
- `gpt-5.6-sol`
- `gpt-5.6-terra`
- `gpt-6-astra`

GPT can be used with the [OpenAI SDK](/en/docs/quickstart-openai-sdk/) and [Codex CLI](/en/docs/quickstart-codex/). Endpoints and billing for different models are governed by the [Console model catalog](https://1zheai.com/model-catalog?lng=en).

## MiMo Models

IDs, supported endpoints and billing units for MiMo text and voice models are on [Models and Pricing](https://1zheai.com/en/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

Models are added or removed as official releases occur; the API response is authoritative:

<CodeGroup>
```bash title="用你的 Key 查"
curl https://1zheai.com/v1/models \
  -H "Authorization: Bearer sk-你的Key"
```
```bash title="公开价格接口（不需要 Key）"
curl -s https://1zheai.com/api/pricing | jq -r '.data[].model_name'
```
</CodeGroup>

## 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](/en/docs/quickstart-claude-code/).

## FAQ

<AccordionGroup>
<Accordion title="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](/en/docs/troubleshooting/).

</Accordion>
<Accordion title="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 support@1zheai.com; you can also follow [Verify Model and Usage](/en/docs/verify-model/) to run the checks.

## 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](/en/docs/api-images/) 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](/en/docs/api-models/).
