The offline translation model mentioned isnt ai model, you just load the plugin then load the zip file mentioned in the translation model page according to which language you want to translate, to use translation you have 3 engine option

auto - if there is plugin loaded/setup correctly/failed to load zip use plugin else ai,

• Use plugin strictly
• use ai
  Ai is unrelated to the plugin, you can use ai without the translation plugin

Here is the setup video: https://youtube.com/shorts/XxtcARqW61s

And you are right i forget to decouple the target language in offline flavours, which makes it impossible to change target language

The error message is misleading. The offline translation feature has two separate model systems. ML Kit translation models (downloaded in-app) work without any GGUF or ONNX model. ONNX local models require manual setup for higher quality.

The No local model selected error means the translation plugin is trying to use the ONNX path. Go to Settings then Translation and look for a model selection option. Switch it to ML Kit or built-in offline if available. The ML Kit models you already downloaded should then work.

If there is no toggle, the offline build may default to expecting an ONNX model. You would need to download an ONNX translation model from Hugging Face (NLLB or M2M100 in ONNX format) and point the plugin to it.

The intent is ML Kit for basic offline translation out of the box, ONNX optional for better quality. The error message just does not make that clear.

ill check , since i mostly use standard full flavour i might lost some of the offline flavour issues
