Gemini 3.1 Pro does not exist — it has not been announced or released by Google DeepMind as of April 2026. The latest model in the Gemini Pro family is Gemini 2.5 Pro, a frontier large language model with native multimodal capabilities, a 1-million-token context window, and freemium pricing starting at $0 for rate-limited access and $1.25 per million input tokens for production API use.
This page exists because users may search for future Gemini Pro versions. Rather than speculate on unannounced products, the information below describes the confirmed Gemini Pro family — specifically Gemini 2.5 Pro — so users can make informed decisions with what is actually available today.
Gemini 2.5 Pro from Google DeepMind provides advanced reasoning, multimodal understanding, and agentic capabilities across text, code, images, audio, and video. It supports a context window of up to 1 million tokens, native multimodal input processing, and enterprise deployment through Vertex AI. Access is available through the free Gemini app at gemini.google.com, Google AI Studio for free API prototyping, Google One AI Premium at $19.99/month for enhanced Workspace integrations, and pay-as-you-go API pricing through Vertex AI.
The Gemini Pro family targets developers, enterprises, researchers, and power users who need frontier-class models for complex reasoning and long-context comprehension. Enterprise deployment via Vertex AI includes IAM, VPC Service Controls, regional data residency, and audit logging. Customer data sent through Vertex AI is not used to train Google's foundation models.
For users evaluating options today: use Gemini 2.5 Pro. It offers competitive performance on language understanding, code generation, and multimodal reasoning, and differentiates on deep integration with Google Workspace and Search, native multimodality, and the largest commercially available context window.

Gemini 2.5 Pro is Google DeepMind's highest-capability Gemini variant, designed for tasks where answer quality matters more than raw speed. It offers iterative improvements in multi-step reasoning and planning over prior generations, complementing the faster but less capable Flash variants. It performs strongly on math, science, and code reasoning benchmarks.
Gemini Pro models accept text, images, audio, video, and code as native inputs rather than via separate adapter models. This allows users to ask questions about screenshots, analyze video clips, transcribe and reason about audio, and review codebases all within a single conversation without needing separate pipelines.
Gemini Pro supports an extended context window of up to 1 million tokens, among the largest in the commercial LLM market. This enables whole-book, long-video (up to several hours), and large-codebase reasoning in a single prompt. Pricing is $1.25/million input tokens under 128K and $2.50/million for longer prompts.
Through Google AI Studio and Vertex AI, Gemini Pro supports structured function calling, tool use, and integration with Google's agent frameworks. Developers can build agents that browse, query databases, call APIs, and execute multi-step plans with the model orchestrating the steps.
Vertex AI offers Gemini Pro models with enterprise-grade controls including IAM, VPC Service Controls, regional data residency, audit logging, and a data-handling policy that excludes customer prompts from foundation model training. This makes the model viable for regulated industries such as finance, healthcare, and government.
