# ListModelsUserRequest

## Fields

| Field | Type | Required | Description | Example |
| - | - | - | - | - |
| `Offset` | optionalnullable.OptionalNullable\[`int64`] | ➖ | Number of records to skip for pagination. When both offset and limit are omitted, the full list is returned | 0 |
| `Limit` | `*int64` | ➖ | Maximum number of records to return (max 1000). When both offset and limit are omitted, the full list is returned | 500 |
| `OutputModalities` | `*string` | ➖ | Filter models by output modality. Accepts a comma-separated list of modalities (text, image, embeddings, audio, video, rerank, decisions, speech, transcription) or "all" to include all models. Defaults to "text". | text |
| `Sort` | [\*operations.ListModelsUserSort](../../models/operations/listmodelsusersort.mdx) | ➖ | Sort the returned models server-side. Prefer this over fetching the full list and sorting client-side. Options: pricing-low-to-high, pricing-high-to-low (average prompt/completion price), context-high-to-low (context length), throughput-high-to-low, latency-low-to-high (recent median performance), most-popular, top-weekly (tokens processed in the last week), newest (creation date), intelligence-high-to-low, coding-high-to-low, agentic-high-to-low (Artificial Analysis indices), design-arena-elo-high-to-low (best Design Arena ELO across arenas). Models without a score for the chosen benchmark are placed last. When omitted, the existing default ordering is preserved. | newest |
| `Client` | [\*operations.Client](../../models/operations/client.mdx) | ➖ | Filter models and presets by the named harness's eligibility policy: tool calling is required, and when one of your guardrails sets `enforce_first_party_harness_models`, only the harness vendor's own models remain (OpenAI for codex, Anthropic for claude\_code and claude\_desktop). When your workspace's Managed Machines policy sets a model list for that harness, only the listed models remain, and a preset remains only while every model it routes to is listed. This filter doesn't apply the harness's ranking, caps or Claude Desktop model ID aliases, so returned IDs stay routable. One of: claude\_code, claude\_desktop, codex. Omit it to get every model you can use. | codex |
