In-depth comparison of Claude Opus 4.5 and Gemini 3 Pro across benchmarks, pricing, context windows, multimodal capabilities, and real-world performance. Discover which AI model best fits your needs. Two AI giants released flagship models within a week of each other in late November 2025. On November 18, Google launched Gemini 3 Pro with the industry's largest context window at 1 million tokens. Six days later, Anthropic responded with Claude Opus 4.5, the first model to break 80% on SWE-bench Verified, setting a new standard for AI-assisted coding. These models represent fundamentally different design philosophies.

Gemini 3 Pro prioritizes scale and multimodal versatility: a 1M token context window, native video/audio processing, and Deep Think parallel reasoning. Claude Opus 4.5 focuses on precision and persistence: Memory Tool for cross-session state, Context Editing for automatic conversation management, and unmatched coding accuracy. This comparison examines where each model excels, where it falls short, and which one fits your specific use case. Claude Opus 4.5 achieves an 80.9% score on SWE-bench Verified, the highest of any AI model. This benchmark tests real GitHub issues: understanding codebases, identifying bugs, and implementing multi-file fixes. For developers working on complex software projects, this represents a step change in AI assistance.

Introduction of Opus 4.5 and Comparison: Completion Time and Cost Analysis (Test 1): Completion Time and Cost Analysis (Test 2): Gemini 3 and Claude Opus 4.5 represent two different answers to the same question. What should a flagship AI optimize for when compute, context, and capability are no longer the primary constraints. One model prioritizes breadth, multimodality, and synthesis at scale. The other prioritizes discipline, correctness, and controlled reasoning. This comparison focuses on how those priorities shape real professional outcomes.

In our AI Weekly Highlights (launched just two days ago), we broke down the two biggest releases: Claude Opus 4.5 and Gemini 3 Pro. From our early experiments and what we are seeing across the developer community, sentiment is consistent: Gemini 3 Pro is becoming the default for multimodal and large-context tasks thanks to strong performance and efficient... At the same time, our developers still default to GPT-5.1 Codex, Gemini 3, Sonnet 4.5, or Composer 1 for faster inference, because Opus 4.5’s small accuracy edge does not justify paying nearly twice the... Before diving into numbers and infrastructure, here’s the core question driving this comparison: What model should you choose depending on your stack, your cost constraints and the type of intelligence your workflows need? Opus 4.5 is a clear capability jump for Anthropic.

Completion Time and Cost Analysis (Test 1): Completion Time and Cost Analysis (Test 2): Three flagship AI coding models launched within weeks of each other. Claude Opus 4.5 on November 24. Gemini 3.0 Pro on November 18. GPT 5.1 Codex-Max on November 19.

All three claim to be the best model for complex coding tasks and agentic workflows. The benchmarks show they're neck-and-neck. I wanted to see what that means for actual development work. So I gave all three the same prompts for two complex problems in my observability platform: statistical anomaly detection and distributed alert deduplication: same codebase, exact requirements, same IDE setup. Here. I compared all these models on some projects I was working on in my spare time.

I've used the Tool router, which is beta, in the first test, which also helps in dogfood the product. Do check out if you're someone who wants to use tools with your agents but doesn't want to be bothered with context pollution. Read more on the tool router here.
