What is Gemini 3.1 Pro ?

Gemini 3.1 Pro is Google’s publicly flagship in the Gemini 3 family, positioned as a state-of-the-art multimodal reasoning model with advanced agentic and developer tooling. The model emphasizes high-capacity context handling (over 1M token inputs), broad media support (images, video, audio, PDF), and deep integrations for tool use, function calling, and code-centric workflows (e.g., Gemini Code Assist and agent modes).

Gemini 3 Pro is presented by Google as optimized for both interactive developer experiences (low-latency coding and agent workflows) and high-fidelity multimodal understanding (interpreting and reasoning across mixed media inputs).

Main Features of Gemini 3.1 Pro

Gemini-3.1 Pro (via its Preview) introduces the following features:

Multimodal Integration

Processes inputs across:

  • Natural language
  • Images
  • Speech/audio
  • Video

with a unified token representation for cross-modal reasoning.

Extended Context Window

An exceptionally large context capacity of up to ~1 million tokens enables handling of:

  • Long documents
  • Multidocument synthesis
  • Codebases and transcripts.

This surpasses many competing models that typically support ~32 K–262 K tokens.

Sparse Mixture-of-Experts (MoE) Scaling

Sparse MoE routing allows scaling internal model capacity without proportional compute costs, improving reasoning at scale.

Advanced Reasoning / Planning

Innovations like chain-of-thought training, reinforcement learning from human feedback, and specialized benchmarks make it strong on logical and mathematical tasks.

Supposed benchmarks:

AIME 2025: 100% (with code execution)
SWE-Bench Verified: 83.9%
ARC-AGI-2: 71.8%
LiveCodeBench Pro: 2844 Elo
Terminal-Bench 2.0: 63.5%
MMMLU: 93.6%

Representative enterprise use cases

  • End-to-end media pipelines: Ingest video, transcript, and images to produce synchronized summaries, metadata, and structured insight at scale.
  • Large-scale code generation and review: Use in IDEs and CI pipelines to auto-generate code, refactor multi-file projects, and produce test suggestions across large codebases.
  • Agentic automation: Coordinate multi-tool agents that interact with cloud services, orchestration systems, and internal APIs using structured function calls.
  • Research & content production: Draft long-form content (reports, books) that combine text and embedded multimedia with internal cross-references preserved.

How to access Gemini 3.1 Pro API

Step 1: Sign Up for API Key

Log in to cometapi.com. If you are not our user yet, please register first. Sign into your CometAPI console. Get the access credential API key of the interface. Click “Add Token” at the API token in the personal center, get the token key: sk-xxxxx and submit.

Step 2: Send Requests to Gemini 3.1 Pro API

Select the “gemini-3.1-pro” endpoint to send the API request and set the request body. The request method and request body are obtained from our website API doc. Our website also provides Apifox test for your convenience. Replace <YOUR_API_KEY> with your actual CometAPI key from your account. base url is Gemini Generating Content and Chat.

Insert your question or request into the content field—this is what the model will respond to . Process the API response to get the generated answer.

Step 3: Retrieve and Verify Results

Process the API response to get the generated answer. After processing, the API responds with the task status and output data.

Gemini 3.1 Pro Sürümleri

Gemini 3.1 Pro'nın birden fazla anlık görüntüye sahip olmasının nedeni; güncellemeler sonrası çıktı varyasyonları nedeniyle tutarlılık için eski anlık görüntülere ihtiyaç duyulması, geliştiricilere uyum ve geçiş için bir geçiş dönemi sağlanması ve kullanıcı deneyimini optimize etmek için küresel veya bölgesel uç noktalara karşılık gelen farklı anlık görüntüler içerebilir. Sürümler arasındaki detaylı farklar için lütfen resmi belgelere başvurun.
