Gemini 2.0 Flash Lite is the lowest-cost multimodal model in Google's 2.0 lineup. This text-output-only model accepts text, images, audio, and documents within a context window of 1.0M tokens, designed for budget-first workloads where output volume drives infrastructure cost.

- Configuration: For data pipelines processing sensitive images or documents at volume, confirm data handling terms with the specific provider before routing production traffic.
- Zero Data Retention: AI Gateway supports Zero Data Retention for this model via direct gateway requests (BYOK is not included). To configure this, check the documentation.
- Authentication: AI Gateway authenticates requests using an API key or OIDC token. You do not need to manage provider credentials directly.
When to Use Gemini 2.0 Flash Lite
Best For
- Image annotation at scale: Labeling, captioning, and attribute extraction across large image datasets where per-image cost determines feasibility
- Audio transcription and summarization pipelines: Processing audio files alongside metadata in a single context, outputting structured text summaries or transcripts
- Document parsing and extraction: Structured data extraction from PDFs, scanned documents, and mixed text-image files where text output is the end product
- Accessibility content generation: Alt-text generation, image descriptions, and audio summaries at the throughput that content libraries require
Consider Alternatives When
- Image or audio output is needed: Gemini 2.0 Flash Lite produces text only. For image generation or native audio output, other Gemini models are more appropriate
- Reasoning depth is required: The 2.0 Lite tier is not a reasoning model. Tasks requiring multi-step chain-of-thought benefit from Gemini 2.5 Flash or 2.5 Pro
- Thinking budgets improve your task: The configurable thinking capability in 2.5-generation models is absent here. For tasks that benefit from deliberation, 2.5 Flash Lite or 2.5 Flash is more appropriate
Conclusion
Gemini 2.0 Flash Lite is the practical choice when multimodal input matters and text output at scale is the requirement. Its text-only output and low cost per token make annotation, extraction, and summarization pipelines economical at volumes that would quickly become expensive with a full multimodal model.
Frequently Asked Questions
Why does Gemini 2.0 Flash Lite only output text when it accepts multimodal inputs?
The text-output-only design focuses the model on tasks where the deliverable is structured text, captions, labels, summaries, or extracted data. This allows cost optimization without removing multimodal understanding from the input side.
What audio formats does Gemini 2.0 Flash Lite accept?
Gemini 2.0 Flash Lite processes audio alongside text in the same request. Refer to the provider documentation for supported audio codecs and file size limits.
How does Gemini 2.0 Flash Lite handle documents with mixed text and images?
Gemini 2.0 Flash Lite processes documents with embedded images, tables, and text as unified inputs within the context window of 1.0M tokens. It produces text descriptions of visual elements alongside extracted textual content.
When should I use 2.0 Flash-Lite instead of 2.5 Flash-Lite?
Gemini 2.0 Flash-Lite is the lower-cost option for annotation and extraction workloads where reasoning capability is not required. If your tasks benefit from configurable thinking or 2.5-generation benchmark improvements, Gemini 2.5 Flash-Lite is the better choice.
What is the cost of Gemini 2.0 Flash Lite per million tokens?
This page lists the current rates. Multiple providers can serve Gemini 2.0 Flash Lite, so AI Gateway surfaces live pricing rather than a single fixed figure.
