Google Gemini 3 vs ChatGPT 5.2
OpenAI released ChatGPT 5.2 on Thursday 11th December 2025. The company claims that it is the most advanced model series to date for professional and enterprise use. The ChatGPT upgrade has arrived at the same time when its competition Google Gemini 3.
Both companies give tough competition to each other. The consensus from recent benchmarks and technical analyses that neither model is definitively “better” overall, both the companies have excelled in different feilds.

Area of Performance |
GPT-5.2 (OpenAI) |
Gemini 3 |
Winner/Specialization |
|
Structured Reasoning |
Leads. Stronger on practical, multi-step planning, enterprise workflows, API orchestration, and structured outputs (spreadsheets, presentations). |
Strong but slightly less reliable on complex, multi-stage execution tasks. |
GPT-5.2 (Execution Stability) |
|
Deep Theoretical Reasoning |
Strong, particularly in the Thinking and Pro tiers (e.g., GPQA Diamond, AIME). |
Leads. Focuses on wider internal reasoning trees, making it excellent in scientific, mathematical, and abstract research environments. |
Gemini 3 (Abstract Depth) |
|
Long-Context Processing |
Leads. Achieved near-perfect accuracy (e.g., 4-needle MRCR) at its largest context size ($\approx 256\text{k}$ tokens). |
Features an extremely large context window ($\approx 1\text{M}$ tokens), but accuracy in very long documents can be lower than GPT-5.2. |
GPT-5.2 (Accuracy in Long Context) |
|
Multimodality & Creativity |
Improved vision understanding (charts, GUI) but still often relies on separate tools (e.g., Sora for video). |
Leads. Superior performance in creative visual media, image generation, video reasoning, and abstract visual analysis (e.g., Video-MMMU, LMArena categories). |
Gemini 3 (Creative Multimodality) |
|
Coding & Agentic Work |
Leads in reliability. Top score on SWE Bench Verified ($\approx 80\%$) and strong tool execution for practical coding and automation pipelines. |
Strong performance, but GPT-5.2 is currently considered more reliable for multi-step production workflows. |
GPT-5.2 (Reliable Coding Agent) |
|
Ecosystem & Integration |
Deeply integrated into the ChatGPT ecosystem (web, app, API) and third-party tools via API. |
Deeply integrated into the Google ecosystem (Search, Workspace, Android, AI Studio). |
TIE (Depends on your existing stack) |
The OpneAI’s ChatGPT 5.2 and Google Gemini 3 are powerful tools that can be used for not only daily use, but it can also help in research, deep thinking and media generation.
