Verified usage

Verified import paths — ran on the pinned version, not inferred.

Gemini

✓ from llama_index.llms.gemini import Gemini

✗ from llama_index.llms import Gemini

Gemini is no longer directly exposed from llama_index.llms; must import from the subpackage.

Initialize Gemini LLM with an API key and generate a completion.

import os from llama_index.llms.gemini import Gemini api_key = os.environ.get("GOOGLE_API_KEY", "") llm = Gemini(api_key=api_key, model="models/gemini-pro") resp = llm.complete("What is the capital of France?") print(resp)

Known issues

breakingIn version 0.2.0+, the import path changed from `llama_index.llms.gemini` to `llama_index.llms.google` (for Google AI) or `llama_index.llms.vertex` (for Vertex AI). This package (`llama-index-llms-gemini`) is deprecated in favor of `llama-index-llms-google`.

fix

Switch to `pip install llama-index-llms-google` and use `from llama_index.llms.google import Gemini`.

affects: >=0.2.0

deprecatedThe `llama-index-llms-gemini` package is deprecated. New projects should use `llama-index-llms-google`.

fix

Use `pip install llama-index-llms-google` and import from `llama_index.llms.google`.

affects: All versions

gotchaGoogle API key must be set either via the `api_key` parameter or the `GOOGLE_API_KEY` environment variable. Not setting it results in an authentication error.

fix

Set `GOOGLE_API_KEY` environment variable or pass `api_key` to the Gemini constructor.

affects: All versions
