## Statements (checkable)
0. Since May 7, 2026, creating fine-tuning jobs or training is not available to organizations that have not previously run fine-tuning.  [✓0 ✗0]
1. Since July 2, 2026, creating fine-tuning jobs is no longer available to organizations that have not run inference on a fine-tuned model in the past 60 days.  [✓0 ✗0]
2. On Jan 6, 2027, active existing customers will no longer be able to create new fine-tuning jobs.  [✓0 ✗0]
3. Inference on fine-tuned models continues and is disabled only when the underlying base model is deprecated (e.g. GPT-4o/4.1 bases shut down Jan 14, 2027).  [✓0 ✗0]

## Fix
```text
Run any remaining fine-tuning jobs before Jan 6, 2027 and plan for no retraining afterwards; check the base model's shutdown date, since fine-tuned inference ends with it.
```
