Generate text with Gemini: prose, code, chat, reasoning. The core generative call.

Generate an image from a text prompt with Gemini (Nano Banana). Saves to output_path.

Edit or combine one or more input images with a natural-language instruction (style transfer, inpainting, compositing). Pass a prior output back in to keep refining. Saves to output_path.

Generate a video from a text prompt with Veo. Async: returns an operation name, then poll video_status. Veo takes 1-3 minutes and is billed per second.

Poll a Veo generation by its operation name. When done, downloads the mp4 to output_path.

Text to speech with Gemini TTS. Saves a WAV to output_path. (Music generation rides with the Live API in a later version.)

Create embedding vectors for one or more texts with Gemini. Writes the vectors to a JSON file and returns the path and dimensions.

Fire a Gemini Deep Research task asynchronously. Returns an interaction_id; poll research_get every 60s. Takes 5-20 minutes, costs roughly $2-5 per task.

Poll a running research task. When complete, saves a cited Markdown report to output_dir and returns the path. Pass the same format/citation/tone used to start it.

Ask a follow-up on a completed research task without re-running it. Returns the answer inline, saves nothing.
