Gemini 3.1 Pro vs Gemini 1.0 Pro

1. Google's most advanced reasoning Gemini model

• Designed to solve complex problems across multimodal inputs, including text, audio, images, video, PDFs, and full code repositories.
• Google highlights improved software engineering behavior, better agentic performance, and stronger usability in domains like finance and spreadsheets.

2. Large multimodal context with substantial output room

• Supports a 1,048,576 token input context window for large repositories, long documents, and multi-source workflows.
• Allows up to 65,536 output tokens for longer answers, plans, and code generations.

3. More efficient thinking with expanded controls

• Improves token efficiency and reasoning performance across use cases.
• Adds the MEDIUM thinking_level option to better balance cost, speed, and quality.

4. Strong support for production agents

• Supports grounding with Google Search, code execution, function calling, structured outputs, context caching, RAG, and chat completions.
• Also offers a custom-tools endpoint tuned for agentic workflows that mix bash-like tools with custom code tools.

1. Strong all-purpose performance

• Designed as Google's balanced middle-tier model.
• Handles a wide range of tasks: reasoning, writing, coding, and problem-solving.

2. Natively multimodal understanding

• Trained from the ground up on text, images, audio, and video.
• More consistent multimodal reasoning than stitched-together architectures.

3. Great cost-to-capability ratio

• Offers much of Gemini Ultra's reasoning quality at a fraction of the cost.
• Strong default choice for large-scale production workloads.

4. Reliable reasoning and factual performance

• Performs well on benchmarks like MMLU, MMMU, and code reasoning.
• Handles long-form analysis, multi-step reasoning, and structured problem solving.

5. Advanced coding capabilities

• Supports major languages such as Python, Java, C++, Go.
• Generates, edits, debugs, and explains code with high accuracy.
• Powers advanced coding systems like AlphaCode 2.

6. Efficient and scalable

• Optimized for Google TPUs for lower latency and faster inference.
• Suitable for batch workloads, agents, and complex multi-step pipelines.

7. Strong multimodal reasoning

• Understands math, physics, and scientific diagrams.
• Handles mixed data inputs (charts + text, screenshots + instructions, etc.).

8. Enterprise-ready reliability

• Available through Google AI Studio and Vertex AI.
• Benefits from enterprise-grade governance, safety, privacy, and compliance.
