In-depth comparison of GPT-5.2 and Gemini 3 Pro across benchmarks, pricing, context windows, and real-world performance. Discover which AI model best fits your needs. The AI landscape has reached an inflection point. On November 18, 2025, Google unveiled Gemini 3 Pro, a model so capable that it reportedly triggered a "code red" response within OpenAI. Less than a month later, on December 11, 2025, OpenAI fired back with GPT-5.2-their most ambitious model yet. But beyond the headline benchmarks lies a more nuanced story.

These models represent fundamentally different architectural philosophies, and their real-world performance diverges in ways that benchmark scores alone don't capture. This comparison goes deeper than the usual spec sheets to examine how each model actually behaves when deployed in production-and why that matters for your specific use case. Before comparing benchmarks, it's worth understanding that GPT-5.2 and Gemini 3 Pro are built on fundamentally different architectural principles. This shapes everything from their strengths to their failure modes. GPT-5.2 introduces a novel self-verification mechanism that fundamentally changes how the model produces responses. Before finalizing any output, GPT-5.2 cross-references its responses against a distilled knowledge graph-a process that adds less than 30 milliseconds of latency but reduces misinformation by approximately one-third in controlled trials.

Get a detailed comparison of AI language models OpenAI's GPT‑5.2 and Google's Gemini 3 Pro, including model features, token pricing, API costs, performance benchmarks, and real-world capabilities to help you choose the right LLM... GPT‑5.2 is OpenAI’s most capable model series for professional knowledge work, delivering stronger long-context reasoning, tool use, and multimodal understanding across Instant, Thinking, and Pro variants. It improves spreadsheet and presentation generation, coding, and complex multi-step projects with better speed and reliability. Gemini 3 Pro is Google's most intelligent model, designed to help bring any idea to life through state-of-the-art reasoning and multimodal understanding. It excels as the world's best model for multimodal tasks and stands as Google's most powerful agentic and coding model, delivering richer visualizations and deeper interactivity. The model significantly outperforms Gemini 2.5 Pro across all major benchmarks, achieving breakthrough scores on reasoning tasks like Humanity's Last Exam and GPQA Diamond, setting new standards in mathematics with MathArena Apex, and demonstrating...

Gemini 3 Pro is 1 months older than GPT‑5.2. Gemini 3 Pro has a larger context window (1M vs 400K tokens). Unlike GPT‑5.2, Gemini 3 Pro supports voice, video processing. Compare costs for input and output tokens between GPT‑5.2 and Gemini 3 Pro. For a few weeks now, the tech community has been amazed by all these new AI models coming out every few days. 🥴 But the catch is, there are so many of them right now that we devs aren't really sure which AI model to use when it comes to working with code, especially as your...

During late 2025, foundation models experienced a dramatic evolution, with Gemini 3 Pro and GPT-5.1 outperforming their predecessors in terms of multimodal capabilities, code generation, and their reasoning depth. The decision to choose between them doesn’t rely on which model is generally “better”, but rather rely on which architectural features best suit your particular technical needs. In this article, we will compare Gemini 3 Pro and GPT-5.1 in various tasks such as generating code, visual reasoning, long-context processing, and deep reasoning. We’ll also understand when each model should be selected for your development process. Gemini 3 Pro is Google’s flagship AI model, which was created as a multimodal reasoning system to process text, images, code, and structured data in a single architecture. The model was released in late 2025, and it can process complex multi-file projects, long documents, or entire codebases in a single session thanks to its 1 million-token context window.

It achieved around 41% on Humanity’s Last Exam and 45.1% on ARC-AGI-2 by introducing Deep Think mode, which gives more computation time for challenging reasoning tasks. Gemini 3 Pro also connects with Google Antigravity, Vertex AI, and the Gemini API for workflows, deployment, and development. Now, let’s see how OpenAI’s GPT-5.1 model faces these challenges. Compare Google's Gemini 3 Pro and OpenAI's GPT-5.1 based on late 2025 benchmarks. Highlight Gemini's superiority in multimodal reasoning and video understanding versus GPT-5.1's 'a As of late 2025, the landscape of generative AI has decisively shifted from conversational chatbots to sophisticated, autonomous agents.

For CTOs and engineering leads, the choice of a foundation model is now one of the most critical architectural decisions. The two dominant players, Google’s Gemini 3 Pro and OpenAI’s GPT-5.1, offer powerful but distinctly different capabilities for building these agentic workflows. This article provides a technical comparison based on projected late-2025 benchmarks and capabilities, helping you select the right engine for your next generation of AI-powered systems. The core challenge in 2025 is no longer just generating accurate text or code. It’s about building agents that can perceive their environment, create multi-step plans, execute tasks using tools, and adapt when things go wrong. Both Gemini 3 Pro and GPT-5.1 are designed for this paradigm, but their underlying architectures reflect their creators’ differing philosophies.

Gemini 3 Pro represents the pinnacle of native multimodality. Unlike earlier models that bolt-on vision capabilities, its architecture is designed from the ground up to process and reason across text, images, audio, and, most importantly, high-fidelity video streams in real time.
