Add Gemini 2.5 Pro (without reasoning) as a model billed as a standard request

Currently, there’s no official way to disable reasoning for Gemini 2.5 Pro in the API, though the community has explored possible prompt‑based methods (https://www.reddit.com/r/Bard/comments/1lefz0f/tip_heres_how_you_can_disable_gemini_25_pro/).

If reasoning could be reliably disabled, Gemini 2.5 Pro would likely produce token output comparable to GPT‑5 without reasoning. Since the API pricing for GPT‑5 and Gemini 2.5 Pro is the same up to 200k tokens of context and GPT-5 without reasoning is billed as a standard request, it would make sense to bill the non‑reasoning version of Gemini 2.5 Pro as a standard request instead of premium.

I really like Gemini 2.5 Pro’s personality, but the current limit of 100 messages per month makes it impossible to daily drive. I understand why it’s billed as premium with reasoning, but I would love to have a non-reasoning version to daily drive.
