> ## Agent Instructions
> Use https://docs.fastino.ai/llms.txt to discover and navigate pages. Use https://docs.fastino.ai/llms-full.txt when you need the complete documentation corpus. Use https://docs.fastino.ai/openapi.json as the source of truth for customer-facing routes. For GLiDE decision inference, call POST https://api.fastino.ai/v1/systemone with model fastino/GLiDE. Create managed config jobs with POST /v1/training/jobs using base_model. For custom training loops, native JSON clients use the public operations under /v1/training/jobs and /v1/training/usage. Existing Tinker clients use tinker==0.32.0 with TINKER_BASE_URL=https://api.fastino.ai/v1/training/compat/tinker and TINKER_CREDENTIAL_CMD. Compatibility child routes are private and absent from OpenAPI. Auto Train is private access and has no public route; direct interested users to sales@fastino.ai. Do not infer undocumented routes. Read API keys from FASTINO_API_KEY and never embed credentials in code, logs, or reports.

# Obtenir un checkpoint interactif

> Renvoie un checkpoint d'un job d'entraînement interactif selon kind et name, où kind vaut weights ou sampler_weights.

`GET /v1/training/jobs/{job_id}/checkpoints/{kind}/{name}`

Returns one checkpoint. To list all of a job's checkpoints, use
[`GET /v1/training/jobs/{job_id}/checkpoints`](/fr/api-reference/training-jobs/checkpoints).

## Request

<ParamField path="job_id" type="string" required>
  Interactive job ID.
</ParamField>

<ParamField path="kind" type="string" required>
  `weights` for a state checkpoint, or `sampler_weights` for a sampler checkpoint.
</ParamField>

<ParamField path="name" type="string" required>
  Checkpoint name.
</ParamField>

<RequestExample>
  ```bash cURL theme={null}
  curl "https://api.fastino.ai/v1/training/jobs/$TRAINING_JOB_ID/checkpoints/sampler_weights/step-000100" \
    -H "X-API-Key: $FASTINO_API_KEY"
  ```
</RequestExample>

## Response

<ResponseExample>
  ```json Response theme={null}
  {
    "checkpoint_id": "sampler_weights/step-000100",
    "checkpoint_type": "sampler",
    "time": "2026-10-14T12:00:00Z",
    "tinker_path": "tinker://SESSION_ID:train:0/sampler_weights/step-000100",
    "size_bytes": 268435456,
    "public": false,
    "user_metadata": null,
    "expires_at": "2026-10-15T12:00:00Z"
  }
  ```
</ResponseExample>

`checkpoint_type` is `training` for a state checkpoint and `sampler` for a
sampler checkpoint. `expires_at` is `null` when the checkpoint has no TTL.
