## Current public model catalogue

The supported model IDs for a key are returned by GET /v1/models and can be filtered by key group and allowed-model settings.

| Model | Model ID | Context | Thinking | Key access |
| --- | --- | --- | --- | --- |
| Claude Opus 5.5 | `claude-opus-5-5` | 1M | Yes | Claude key groups |
| Claude Fable 5.1 | `claude-fable-5-1` | 1M | Yes | Claude key groups |
| Claude Opus 5 | `claude-opus-5` | 1M | Yes | Basic, Pro |
| Claude Fable 5 | `claude-fable-5` | 1M | Yes | Basic, Pro |
| Claude Opus 4.8 | `claude-opus-4.8` | 1M | Yes | Claude key groups |
| Claude Opus 4.7 | `claude-opus-4.7` | 1M | Yes | Claude key groups |
| Claude Opus 4.6 | `claude-opus-4.6` | 1M | Yes | Claude key groups |
| Claude Sonnet 5 | `claude-sonnet-5` | 1M | Yes | Claude key groups |
| Claude Sonnet 4.6 | `claude-sonnet-4.6` | 1M | Yes | Claude key groups |
| Claude Haiku 4.5 | `claude-haiku-4.5` | 200K | Yes | Claude key groups |

### Short aliases

| Alias | Resolves to |
| --- | --- |
| `opus` | `claude-opus-5-5` |
| `sonnet` | `claude-sonnet-4.6` |
| `haiku` | `claude-haiku-4.5` |

The definitive list for a specific key is always GET /v1/models. Do not hard-code the catalogue in production.

## Enterprise AI API

LLMsRelay Enterprise is an AI API gateway workflow for teams that need compatible Anthropic Messages API and OpenAI-compatible endpoints, account-level usage visibility, model access by key group, and direct onboarding.

- [Enterprise documentation entry](https://llmsrelay.com/docs/getting-started/quickstart/)
- [Plans](https://llmsrelay.com/plans/)

## GPT channel

LLMsRelay exposes a dedicated OpenAI-compatible GPT channel for coding, reasoning, and agent workloads. The public catalogue contains exactly the five model IDs below.

- `gpt-5.5`
- `gpt-5.6-sol`
- `gpt-5.6-terra`
- `gpt-6-sol`
- `gpt-6-astra`

Removed and internal upstream model IDs are not accepted and are not returned by GET /v1/models.

## Controlled-access open models

DeepSeek and Qwen use a controlled private-access workflow. Register first, then LLMsRelay confirms GPU capacity, licensing, commercial terms, the account-specific model ID, and rollout timing. GLM has a separate self-service API flow described below.

- [DeepSeek V4.1 Flash Uncensored 750B](https://llmsrelay.com/models/deepseek-v4-1-flash-uncensored/) — 750B-class listing · FP8 checkpoint · approximately 510 GB
- [Qwen 3.8 Flash Uncensored 120B](https://llmsrelay.com/models/qwen-3-8-flash-uncensored/) — 120B-class checkpoint · NVFP4 · approximately 135 GB

- [Register and request access](https://llmsrelay.com/auth/?mode=signup)

These checkpoint names are not a promise that they are already returned by the public GET /v1/models catalogue. The account catalogue and an explicit capacity confirmation remain the source of truth.

GLM 5.3 Uncensored 750B: use a GLM 5.3 key and the separate USD wallet, funded 1:1 with $45, $100, $500 or $1000. No bonuses. Public IDs: glm-5-3-uncensored (262144 context, text/images) and glm-5-3-uncensored-1m (1000000 context, text only). Both support Messages and Chat Completions.
