On Terminal-Bench 2.0 it achieved 54.2 percent versus 32.6 percent previously. SWE-Bench Verified, which measures agentic coding through structured fixes, increased from 59.6 percent to 76.2 percent. The model also posted 85.4 percent on t2-bench, up from 54.9 percent.Long-context and planning benchmarks indicate more stable multi-step behavior. Gemini 3 achieved 77 percent on MRCR v2 at 128k context (versus 58 percent) and 26.3 percent at 1 million tokens (versus 16.4 percent). Its Vending-Bench 2 score reached $5,478.16, compared to $573.64 for Gemini 2.5 Pro, reflecting stronger consistency during long-running decision processes.Language understanding scores improved on SimpleQA Verified (72.1 percent versus 54.5 percent), MMLU (91.8 percent versus 89.5 percent), and the FACTS Benchmark Suite (70.5 percent versus 63.4 percent), supporting more reliable fact-based work in regulated sectors.Generative Interfaces Move Gemini Beyond TextGemini 3 introduces a new class of generative interface capabilities. Visual Layout produces structured, magazine-style pages with images, diagrams, and modules tailored to the query. Dynamic View generates functional interface components such as calculators, simulations, galleries, and interactive graphs. These experiences now appear in Google Search’s AI Mode, enabling models to surface information in visual, interactive formats beyond static text.Google says the model analyzes user intent to construct the layout best suited to a task. In practice, this includes everything from automatically building diagrams for scientific concepts to generating custom UI components that respond to user input.Gemini Agent Introduces Multi-Step Workflow AutomationGemini Agent marks Google’s effort to move beyond conversational assistance toward operational AI. The system coordinates multi-step tasks across tools like Gmail, Calendar, Canvas, and live browsing. It reviews inboxes, drafts replies, prepares plans, triages information, and reasons through complex workflows, while requiring user approval before performing sensitive actions.On the press call, Google said the agent is designed to handle multi-turn planning and tool-use sequences with consistency that was not feasible in earlier generations. It is rolling out first to Google AI Ultra subscribers in the Gemini app.Google Antigravity and Developer Toolchain IntegrationAntigravity is Google’s new agent-first development environment designed around Gemini 3. Developers collaborate with agents across an editor, terminal, and browser. The system orchestrates full-stack tasks, including code generation, UI prototyping, debugging, live execution, and report generation.Across the broader developer ecosystem, Google AI Studio now includes a Build mode that automatically wires the right models and APIs to speed up AI-native app creation. Annotations support allows developers to attach prompts to UI elements for faster iteration. Spatial reasoning improvements enable agents to interpret mouse movements, screen annotations, and multi-window layouts to operate computer interfaces more effectively.Developers also gain new reasoning controls through “thinking level” and “model resolution” parameters in the Gemini API, along with stricter validation of thought signatures for multi-turn consistency. A hosted server-side bash tool supports secure, multi-language code generation and prototyping. Grounding with Google Search and URL context can now be combined to extract structured information for downstream tasks.Enterprise Impact and AdoptionEnterprise teams gain multimodal understanding, agentic coding, and long-horizon planning needed for production use cases. The new model unifies analysis of documents, audio, video, workflows, and logs. Improvements in spatial and visual reasoning support robotics, autonomous systems, and scenarios requiring navigation of screens and applications. High-frame-rate video understanding helps developers detect events in fast-moving environments.Gemini 3’s structured document understanding capabilities support legal review, complex form processing, and regulated workflows. Its ability to generate functional interfaces and prototypes with minimal prompting reduces engineering cycles. In addition, the gains in system reliability, tool-calling stability, and context retention make multi-step planning viable for operations like financial forecasting, customer support automation, supply chain modeling, and predictive maintenance.Developer and API PricingGoogle has disclosed initial API pricing for Gemini 3 Pro. In preview, the model is priced at $2 per million input tokens and $12 per million output tokens for prompts up to 200,000 tokens in Google AI Studio and Vertex AI.
