Completion Time and Cost Analysis (Test 1): Completion Time and Cost Analysis (Test 2): 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. Opus 4.5 nudged past Gemini 3 Pro on coding and long‑task benchmarks. The win matters for real tasks, not just flashy demos.

Opus 4.5 posts modest but meaningful wins over Gemini 3 Pro on agentic coding and long‑horizon tasks. Those wins matter for workflows that require tool use, multi‑step planning, and sustained context. Benchmarks vary, so test models on the tasks you actually need and weigh performance against cost. Most model releases read like scoreboards. New numbers. New bragging rights.

Opus 4.5 matters because its wins map to useful work. That changes how you might pick a model for coding, long tasks, or using apps. Anthropic's Opus 4.5 landed right after Gemini 3 Pro and outscored it on several practical fronts. On SWE agentic coding benchmarks Opus hit 80.9 versus Gemini 3 Pro's 76.2. On ARC AGI-style computer use tests Opus also topped earlier Anthropic models and set new marks for released frontier models. 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. November 2025 was the most intense month in AI history: three tech giants released their flagship models within just six days of each other. We break down the benchmarks, pricing, and real-world performance to help you choose the right model for your needs.

In an unprecedented week, all three major AI labs released their flagship models, creating the most competitive AI landscape we've ever seen: Here's how the three models stack up on the most important benchmarks for developers and enterprises: Measures ability to solve actual GitHub issues from real software projects Tests advanced academic knowledge across physics, chemistry, and biology This YouTube insight note was created with LilysAI.

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 daily... Just a few weeks ago, Anthropic released Opus 4.5, Google released Gemini 3, and OpenAI released GPT-5.2 (Codex), all of which claim at some point to be the "so-called" best for coding. But now the question arises: how much better or worse is each of them when compared to real-world scenarios? If you want a quick take, here is how the three models performed in these tests:
