Dynamic Reasoning

### Controllable thinking budget

Automatically adjusts processing time based on query complexity for optimal speed-accuracy balance.

Massive Context

### 1M token window

Process 3,000 images, 8.5 hours of audio, entire codebases, and long documents in single requests.

Cost Efficient

### 20-30% fewer tokens

Reduced verbosity and optimized output generation lower inference costs without sacrificing quality.

[Read the docs ](https://docs.modelslab.com)

### What is Google Gemini 2.5 Flash?

Google Gemini 2.5 Flash is a multimodal LLM optimized for speed and cost-efficiency, featuring a 1M token context window and dynamic thinking capabilities. It handles text, code, images, audio, and video inputs while maintaining competitive pricing and low latency.

### How does the thinking feature work?

The model automatically adjusts its reasoning budget based on query complexity, enabling faster answers for simple requests and deeper analysis for complex problems. You can also manually control the thinking budget for fine-grained speed-accuracy tuning.

### What are the input limitations?

Maximum 3,000 images per prompt (up to 7 MB each via console, 30 MB from Cloud Storage), 8.5 hours of audio, and video files. Text and code inputs scale within the 1M token context window.

### How does Gemini 2.5 Flash compare to alternatives?

Flash offers better agentic tool use, improved multimodal capabilities, and 20-30% lower token costs than previous versions. It balances speed and intelligence better than Flash-Lite while remaining significantly cheaper than Pro models.

### What is the knowledge cutoff date?

The model's training data extends through January 2025, ensuring recent information for most queries. For real-time data, use grounding with Google Search integration.

### Does it support function calling and structured output?

Yes, Gemini 2.5 Flash supports function calling, structured output, system instructions, and code execution. It also supports context caching for optimized performance on repeated requests.
