## about

Google's thinking model lets developers set a reasoning budget from 0 to 24,576 tokens per request, creating a [6x cost spread](https://deepmind.google/technologies/gemini/flash/) between instant responses at $0.60/1M output and full chain-of-thought at $3.50/1M. With thinking enabled, it scores 88.0% on AIME 2024 and 60.4% on SWE-bench Verified, while running at 214.7 tokens per second.

### Is Google Gemini 2.5 Flash free?

Gemini 2.5 Flash is available with free usage limits through Google AI Studio. Production API access through [Vertex AI](https://docs.cloud.google.com/vertex-ai/generative-ai/docs/models/gemini/2-5-flash) and inference providers involves usage-based pricing.

### Is the Gemini 2.5 Flash better?

Gemini 2.5 Flash introduces a "thinking" mode for step-by-step reasoning, significantly improving performance on math, coding, and analysis tasks over 2.0 Flash. It is available through  and other inference platforms.

1,048,576

## Use cases for Gemini-2.5-Flash

1. **Budget-controlled deep reasoning:** A tunable thinking budget from 0 to 24,576 tokens creates a 6x cost spread per request, allowing developers to allocate reasoning depth per query based on complexity.
2. **High-throughput STEM processing:** Scoring 88.0% on AIME 2024 and 82.8% on GPQA Diamond at 214 tokens per second, it handles volume math, science, and coding tasks with strong accuracy.
3. **Multimodal data extraction:** Native text, vision, and audio input at $0.30 per million input tokens makes it cost-effective for processing mixed-media documents like PDFs with embedded images, charts, and tables.

## Quality

Arena Elo1411

MMLUN/A

MT BenchN/A

Gemini 2.5 Flash scores 88.4% on Global-MMLU-Lite and 88.0% on AIME 2024 with its thinking budget enabled. Its Arena ELO of 1,411 places it above GPT-4.1 (1,413 is close) and near Qwen3 235B (1,422) on the same sheet. The controllable thinking budget from 0 to 24,576 tokens creates a 6x cost spread, allowing developers to trade reasoning depth for latency per request.

## pricing

Running Gemini 2.5 Flash through Telnyx Inference costs $0.30 per million input tokens and $2.50 per million output tokens (non-thinking). Processing 1,000,000 reasoning tasks at 2,000 tokens each would cost approximately $2,800, with the tunable thinking budget allowing developers to reduce cost by up to 6x on simpler queries.

## What's Twitter saying?

* **Controllable reasoning depth:** Developers highlight the [tunable thinking budget from 0 to 24,576 tokens](https://blog.google/technology/google-deepmind/gemini-model-thinking-updates-march-2025/) as the standout feature, creating a 6x cost spread per request based on task complexity.
* **Benchmark leader at speed:** Artificial Analysis ranks Gemini 2.5 Flash at [214 tokens per second with 88% on AIME 2024](https://artificialanalysis.ai/models/gemini-2-5-flash), placing it among the fastest reasoning models available.
* **Cost-performance tradeoff:** Developers on r/LocalLLaMA note that the [$0.30 per million input tokens](https://www.reddit.com/r/LocalLLaMA/) pricing makes it competitive with open-weight models for high-volume reasoning workloads.
