DeepSeek V4-Flash-0731
DeepSeek's July API version documentation says the `deepseek-v4-flash` alias was updated to V4-Flash-0731. The API alias was later retired on September 10 and temporarily routes to V4.1-Flash; the available first-party receipt does not establish the downloadable checkpoint's modality or architecture.

Practical fit
Historical API/checkpoint identity only. For a current hosted route, consult DeepSeek's live model and pricing pages; do not assume a local checkpoint is equivalent.
Deployment note
The available first-party receipts do not establish exact checkpoint parameter count, license, or a supported self-hosting recipe.
