What Gemini 3.8 Flash does

It always thinks. Send a prompt, or a chat history in messages with images as image_url parts, and get a text answer from a 1M-token context. reasoning_effort is low, medium or high (medium by default) and max_tokens caps the answer at up to 65,536 tokens; system_prompt works as usual, and private_mode keeps the prompt and answer out of FlyMy.AI storage. Your FlyMy.AI key also works on the OpenAI-compatible Chat Completions endpoint and on Google's generateContent API at the model's FlyMy.AI address, so the official Google GenAI SDK runs once you change its base URL; that route also takes audio, video and PDF. Billing follows the tokens Google reports, at Google's own price. Tools Google runs itself, such as Search grounding, are not offered.
