Which ID should I use to call Gemini 3.8 Flash?
Use Chat Completions, set model to gemini-3.8-flash, organize text and images in messages, and read responses from choices; for streaming interactions, handle incremental updates as documented. The capabilities and message format of native Generate Content should be checked independently; do not infer that the platform exposes all features from the provider's native specifications.
How do I submit images for analysis?
Combine text and image_url content blocks in the message content of Chat Completions, and place the image address in image_url.url. You can use a publicly accessible image URL or a Base64 data URI, and describe in the text the area, question, and expected output to analyze.
How do I choose the thinking level?
This model natively supports low, medium, and high, but not minimal. Lower thinking levels can be used for simple tasks, while higher levels can be used for complex analysis; when calling through the platform, set the corresponding parameter only when the selected interface explicitly supports the thinking-level configuration for this model. For Chat Completions, it is recommended to set max_tokens to 512 or higher and increase the budget according to task complexity, leaving room for both reasoning and the final answer; more than 512 does not guarantee a sufficient budget.
Can it read PDFs and generate speech?
Prepare document text, table data, or clear page screenshots relevant to the question, and specify whether you need a summary, comparison, or extraction of particular information. Submit content in formats supported by the selected public interface; a PDF address cannot be used as image_url. Require results to retain original locations, field evidence, and unconfirmed items, and verify key numbers against the source material.
How can I make results easy for programs to process?
You can use response_format to select a JSON object or JSON Schema, and clearly specify field meanings, required fields, and how missing values should be handled. The client should still validate the returned structure and business rules; when business functions need to be called, use tools to define functions, then process the call parameters and feed back the execution results.
