Larger custom dictionary, voice fine-tuning, and free system instruction for the custom API

The dictionary limit is the main thing holding the free tier back

I'm a Vowen user, and the 50-word dictionary cap is honestly the only free-tier restriction that gets in my way. I'd happily see a much larger dictionary as a paid feature - it would be genuinely valuable for me and several people around me. For reference, wisprflow.ai lets you add thousands of words and tunes the system around them (optimal LLM prompts, etc.).

I've set up a small model that runs locally on my laptop and proofreads my transcribed text. It comfortably handles far more than 50 words using the language model alone - I'd estimate 500 - 1000 words without trouble on my hardware, and I'd expect the same via API requests. So the technical ceiling is much higher than the current limit suggests.

The feature I'd really love: personal fine-tuning

What would be amazing is a way to fine-tune the model specifically for me - for my voice and my vocabulary. If there's any way I can help test or contribute to this, I'm in.

Feedback: please don't paywall the system instruction on the custom API

Locking the LLM system instruction behind a paywall doesn't make much sense. It's trivial to work around - with LM Studio, Llama, or any other provider, I can set a system instruction at the provider's own level when connecting the model. So a paid system instruction just pushes me to configure it elsewhere. Given that it used to be free, the better move is the opposite: keep the system instruction as a free feature.
