# deepseek-v4-flash

Tinfoil deprecated the model deepseek-v4-flash without giving a shutdown date yet.

The deepseek-v4-flash model has been deprecated and retired without a shutdown date announced in advance. Calls requesting model deepseek-v4-flash on inference.tinfoil.sh fail because Tinfoil removed it from the catalog.

## What to use instead

Switch to DeepSeek V4.1 Flash (deepseek-v4-1-flash) instead.
