## Request

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | The name of the generation to get. Required. |

## Response

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | `orgs/{org}/projects/{project}/envs/{env}/generations/{generation}`. |
| `uid` | `string` | `gen_<cell><ulid>`; never reused. Output only. |
| `meta` | `ResourceMeta` | Resource metadata. |
| `trace_id` | `string` | The W3C trace id (32 hex); the caller's own when it sent `traceparent`. Output only. |
| `span_id` | `string` | The W3C span id (16 hex) of the gateway's span. Output only. |
| `operation` | `string` | `gen_ai.operation.name`, for example `chat`, `embeddings` or `generate_content`. Output only. |
| `api_surface` | `string` | The wire the call used: `responses`, `messages`, `chat_completions`, `embeddings`, `images`, `audio` or `realtime_transcription`. Output only. |
| `request_model` | `string` | The catalogue model id the caller named, for example `anthropic/claude-sonnet-5.5`. Output only. |
| `response_model` | `string` | The catalogue model id that answered. Output only. |
| `response_id` | `string` | The response id (`resp_...`, `msg_...` or `chatcmpl-...`). Output only. |
| `api_key` | `string` | The key that made the call, as a resource name. Output only. |
| `outcome` | `GenerationOutcome` | How the call ended. Output only. One of `succeeded`, `failed`, `cancelled`. |
| `finish_reasons` | `string[]` | `gen_ai.response.finish_reasons`, for example `stop` or `length`. Output only. |
| `error_type` | `string` | `error.type` when the call failed: the public error code, for example `rate_limited`. Output only. |
| `input_tokens` | `int64` | Input tokens, cached ones included. Output only. |
| `output_tokens` | `int64` | Output tokens, reasoning ones included. Output only. |
| `cache_read_input_tokens` | `int64` | Input tokens read from the prompt cache. Output only. |
| `cache_write_input_tokens` | `int64` | Input tokens written to the prompt cache. Output only. |
| `reasoning_output_tokens` | `int64` | Output tokens spent on reasoning. Output only. |
| `price_usd` | `string` | What the call was charged in USD, as a decimal string, for example `0.000420`; the same value as the response's `usage.sylphx.price`. Output only. |
| `start_time` | `timestamp` | When the gateway received the call. Output only. |
| `end_time` | `timestamp` | When the last byte of the answer was sent. Output only. |
| `time_to_first_chunk` | `duration` | From receipt to the first output chunk; unset when nothing streamed. Output only. |
| `streamed` | `bool` | Whether the answer was streamed. Output only. |
| `data_policy` | `string` | The data policy the call ran under: `standard`, `zdr` or `training`. Output only. |
| `tags` | `map<string, string>` | The caller's tags (`Sylphx-Tags` and the request's `metadata`), at most 64; filter as `tags.<key> = "value"`. Output only. |
| `end_user` | `string` | The caller's own end-user id (`user` or `safety_identifier`), as sent. Output only. |

### ResourceMeta

| Field | Type | What it is |
| --- | --- | --- |
| `generation` | `int64` | Increases by one on every change to `spec`. Output only. |
| `etag` | `string` | Strong ETag (AIP-154): changes on any change to spec, status, or metadata. Send it back as `If-Match` or `etag` to make Update and Delete conditional; a mismatch fails with ABORTED / 409 `ETAG_MISMATCH`. Output only. |
| `create_time` | `timestamp` | When the Resource was created. Output only. |
| `update_time` | `timestamp` | When the Resource last changed. Output only. |

## Errors

- [`UNAUTHENTICATED`](/docs/api/errors/UNAUTHENTICATED) — No valid key or token was presented.
- [`PERMISSION_DENIED`](/docs/api/errors/PERMISSION_DENIED) — The key lacks the method's permission.
- [`RESOURCE_NOT_FOUND`](/docs/api/errors/RESOURCE_NOT_FOUND) — The named Resource does not exist or is not visible.

Every error arrives in the body [Errors](/docs/platform/errors) describes.
