DeepSeek V4 Flash Free is not showing in the model list

Description

The DeepSeek V4 Flash Free model is not available in the model selection list. I also tried adding my OpenCode Zen API key, but after entering the API key, the DeepSeek V4 Flash Free model still does not appear in the available models.

Expected behavior:

DeepSeek V4 Flash Free should appear in the model list when supported by OpenCode Zen.
After entering a valid OpenCode Zen API key, the available models should be detected and displayed.

Actual behavior:

DeepSeek V4 Flash Free is missing from the model list.
Adding the OpenCode Zen API key does not make the model appear.

Could you please check whether DeepSeek V4 Flash Free is currently supported/enabled, and whether there is an issue with OpenCode Zen model detection?
