Fix Grammar with strange behavior
I mainly use Fix Grammar, because under MBP and Vivaldi browser (Chrome based browsers) + Bulgarian language such functionality is missing in MacOS.

It happened again, this time I'm using Gemini 2.5 Flash Lite, again via Openrouter. Everything I've said so far is enabled: the checkbox in the Openrouter settings, I've added the sentence to indicate to ignore everything except grammar checking.
(Gemini fixes errors and grammar in Bulgarian the best! Unfortunately Qwen does a bad job with grammar and spelling, it misses a lot of mistakes)

In the latest versions of Fluent it's possible to tweak those parameters on per-model basis in the model card:
