Gemini 3 Pro delivers a unified multimodal foundation for developer, research, and enterprise automation.
Gemini 3 Pro is engineered as Google’s premier all-in-one model for text, code, images, and audio, tailored for both technical and creative use cases. Its architecture enables seamless ingestion and output of complex, interleaved inputs—including documents with embedded diagrams, annotated audio transcripts, or entire software repositories—making it a universal tool for a new generation of developers, analysts, and content creators.
The model’s most striking capability is its context window: up to 1 million tokens in preview tiers, allowing teams to feed entire books, research archives, or live codebases into a single prompt. This unlocks use cases such as full-project summarization, code refactoring across hundreds of files, and multi-source research aggregation that were previously impossible for any commercial LLM.
For development teams, Gemini 3 Pro’s deep integration with agentic tools—including terminal commands, browser automation, code execution, and API plugin workflows—represents a leap beyond autocomplete or basic chat. Developers can supervise multi-stage agent tasks, with the model producing actionable output, structured artifacts, and full audit trails to ensure quality and compliance.
Google has also prioritized real-world applicability: Gemini 3 Pro’s knowledge extends up to January 2025, ensuring its outputs reflect the latest web standards, scientific discoveries, and security best practices. Its reliability in multi-turn reasoning and artifact generation supports both solo coders and distributed engineering teams in high-stakes environments.

Gemini 3 Pro enables complex agentic coding, parallel tool workflows, and auditable automation.
The single defining trait of Gemini 3 Pro is its leadership in agentic coding and tool-driven orchestration. Unlike traditional language models that generate static outputs, Gemini 3 Pro can break down tasks, chain multiple tool calls, and validate results through stepwise execution—mirroring the cognitive process of an experienced developer.
Industry benchmarks confirm its edge:
Terminal-Bench 2.0: Gemini 3 Pro achieves 54.2%, significantly surpassing prior models in executing code, troubleshooting, and interacting with real-world command-line environments.
Multi-agent orchestration: The model is optimized for environments like Google Antigravity, where agents operate in parallel across editor, terminal, and browser, each producing independent artifacts and logs for end-to-end traceability.
Within Antigravity, developers leverage Gemini 3 Pro’s agentic workflows to perform simultaneous code audits, integration testing, UI scaffolding, documentation updates, and browser-based validation. These agents not only execute commands but also reason about dependencies, suggest improvements, and surface errors—all captured in transparent, reviewable artifacts.
This workflow transforms the traditional developer role, moving from hands-on editing to high-level supervision, governance, and architectural oversight—enabling organizations to automate processes at scale while maintaining the ability to trace, debug, and certify every action taken by the model.

Gemini 3 Pro offers dramatically lower pricing and broader availability than previous Google models.
Google’s new pricing structure for Gemini 3 Pro makes it the most accessible high-capacity model ever released by the company. For developers and enterprises accustomed to the high costs of Gemini 1.5 Pro or even Gemini 2.5 Pro, this shift redefines what is possible for large-scale automation, code review, and data analysis:
Input cost: approximately $0.10 per 1 million tokens, compared to $1.25 for Gemini 1.5 Pro—a 12.5x cost reduction.
Output cost: approximately $0.40 per 1 million tokens, compared to $5.00 for Gemini 1.5 Pro—again, more than 10x cheaper.
The reduction in token costs is transformative for workflows that require bulk document analysis, continuous integration, or long-context code generation—making these features available to startups, students, and research teams previously priced out of enterprise-grade AI.
Gemini 3 Pro is now available on:
Google AI Studio (for prompt engineering, research, and testing)
Vertex AI (Google Cloud’s platform for production API access and enterprise deployment)
Google Antigravity (the agentic IDE purpose-built for Gemini 3 Pro)
Gemini CLI and the Gemini app (bringing multimodal and agentic AI directly to end-users)
Feature and Pricing Comparison: Gemini 3 Pro, Gemini 2.5 Pro, and Gemini 1.5 Pro
Feature | Gemini 3 Pro | Gemini 2.5 Pro | Gemini 1.5 Pro (002) |
Maximum context window | Up to 1,000,000 tokens | Up to 1,000,000 tokens | Up to 1,000,000 tokens |
Input/output pricing | ~$0.10/$0.40 per 1M tokens | ~$0.50/$1.50 per 1M tokens | $1.25/$5.00 per 1M tokens |
Modalities | Text, code, image, audio | Text, code, image | Text, code, image |
Agentic coding | Full agentic, tool-integrated | Partial | Basic |
Artifact generation | Yes, native and auditable | Partial | No |
Deployment platforms | AI Studio, Vertex, Antigravity, Gemini app/CLI | AI Studio, Vertex | AI Studio, Vertex |
This broader availability and pricing flexibility means organizations can experiment, prototype, and scale workflows without budgetary friction.

Deep integration with Google Antigravity enables real-time agent orchestration and transparent development pipelines.
Gemini 3 Pro’s tight integration with Google Antigravity sets a new benchmark for agentic coding environments. Antigravity is the first public IDE designed from the ground up to support multi-agent, artifact-rich, and tool-driven development—fully powered by Gemini 3 Pro’s reasoning, tool use, and context management.
Within Antigravity, developers can orchestrate parallel agent clusters that:
Run independent audits on different modules of a codebase
Generate comprehensive test suites
Refactor application layers and APIs simultaneously
Automate documentation updates with browser-verified facts
Review, approve, or roll back changes based on stepwise artifact evidence
The artifact system in Antigravity ensures every agent action is logged, timestamped, and traceable. This visibility is critical for compliance in regulated environments, continuous integration, or security-sensitive workflows. Developers and teams can review every code change, test result, or browser action, providing a level of transparency and auditability not possible with previous LLM platforms.
As agentic environments mature, Gemini 3 Pro’s performance and scalability are expected to drive industry standards in software engineering, enterprise automation, and beyond.

Practical steps for adopting Gemini 3 Pro and integrating it with modern workflows.
To fully realize the benefits of Gemini 3 Pro, organizations should adopt a structured approach to exploration and integration:
Start with Google AI Studio: Test large-context prompts, document ingestion, and code refactoring tasks to benchmark performance and output quality.
Experiment with agentic workflows: In Antigravity or Vertex AI, launch agent-driven processes for parallel testing, code analysis, or documentation alignment—review artifacts and logs for transparency.
Compare costs and throughput: Benchmark Gemini 3 Pro against older models in high-volume scenarios to quantify cost savings and productivity gains.
Integrate into CI/CD: Gradually connect agentic operations with continuous integration systems, setting up governance frameworks for artifact storage, agent permissions, and code approval pipelines.
Train teams on audit and validation: Teach developers and project leads to leverage artifact trails for debugging, compliance checks, and quality control.
A staged rollout, starting with pilot projects and expanding to core workflows, enables organizations to de-risk adoption and optimize for both technical and operational gains.
