API model ID: gemini-2.5-flash

Capabilities & boundaries

What it supports. Where the limits are.

Tool support requires the appropriate API integration; a supported tool is not automatically active in every chat.

Supported API features and tools

  • Multimodal understanding with text output
  • Function calling and structured outputs
  • Search grounding, Maps grounding, and URL context
  • Code execution and file search
  • Context caching and Batch API

Before you choose

  • No native image or audio generation; use a dedicated generation model.
  • The Live API is not supported by this model.
  • Large input capacity does not guarantee that every detail will be recovered correctly.
  • Stable-model access is restricted to prior Google API users; old preview IDs have separate retirement dates.

Extended thinking

Dynamic thinking is the default. Set a budget from 0–24,576 tokens; 0 disables thinking and -1 restores dynamic allocation. Thinking consumes output tokens, so reserve enough room for the answer.

  • This page documents the stable API ID shown above, not an earlier preview mentioned in the launch article.
  • Gemini 2.5 uses thinkingBudget rather than Gemini 3 thinkingLevel; do not copy reasoning defaults between generations.
  • Tool execution, permissions, and validation belong to the application integrating the API. Always inspect citations and generated structured data.

Workflow 01

Turn meeting notes into actions

Separate explicit commitments from suggestions.

From the meeting notes below, extract decisions, action items, owners, and deadlines. Quote the phrase supporting each assignment. Mark missing owners or dates as unassigned instead of inventing them. List unresolved questions separately and finish with a short summary suitable for attendees.

Workflow 02

Review a product walkthrough

Use a supplied recording only where video input is available.

Review this product walkthrough video for onboarding friction. For each observation include a timestamp, what is visible, the likely user question, and a proposed test. Distinguish what the recording proves from what would require interaction. Prioritize three improvements without redesigning the entire product.

Workflow 03

Prepare a structured incident brief

Keep chronology and uncertainty explicit.

Convert these incident updates into a structured brief with timeline, customer impact, confirmed cause, mitigations, and follow-up tasks. Cite the update supporting each claim. Preserve contradictory reports as open questions. Do not state that the incident is resolved unless a supplied update explicitly confirms recovery.

  • Prices are standard paid-tier API reference rates checked October 6, 2026. Free-tier terms and Batch, Flex, or Priority rates differ; verify the selected service tier before estimating spend.
  • Output pricing includes thinking tokens. Cached reads and cache storage are separate costs.
  • Search grounding includes 1,500 free requests per day on the paid tier, shared between 2.5 Flash and Flash-Lite; Maps has its own 1,500-per-day paid-tier allowance.

Common questions

A few things worth knowing.

What is Gemini 2.5 Flash useful for?

Consider it for repeatable multimodal analysis and batch workflows. Supply clear constraints and assess correctness, latency, and total usage on your own examples before making it a default.

How should I configure thinking?

Dynamic thinking is the default. Set a budget from 0–24,576 tokens; 0 disables thinking and -1 restores dynamic allocation. Thinking consumes output tokens, so reserve enough room for the answer.

Can I send images, audio, or video?

The Google model card supports these inputs and text output. Upload and tool availability depend on your integration. This does not make the model an image generator, voice generator, or Live API model.

Is this model retired?

No. Google says the stable 2.5 models remain served, with access limited to users who actively used them before. Retired preview IDs are different. Check current provider and EZ Ai Assist availability independently.

What costs are additional to input and output tokens?

Cache storage and grounding can add charges beyond ordinary input/output tokens. Audio input has a separate rate where shown. Review the units and free allowances in the provider pricing page.

Does the large input limit guarantee a correct answer?

No. Keep evidence relevant, specify the required output, request source references, and check the result. The 1,048,576 input-token limit and 65,536 output-token limit are different constraints.

Are these the prices and limits of my EZ Ai Assist plan?

No. This guide separates Google’s direct API reference from EZ Ai Assist subscriptions. Use the pricing page for plans and the app for current model access. The example prompts are starting points, not guaranteed results.
