🧠 Why Claude Opus 4 Is the New Developer Powerhouse

Let’s not sugar-coat it—Claude Opus 4 dominates most technical benchmarks:

SWE-bench and TAU-bench results place it at the top of AI coding capabilities, outperforming OpenAI in both static and interactive tasks.
With 200,000 token context, Claude can ingest entire codebases, documentation, and workflows—game-changing for large enterprise tasks.
It’s also smarter at reasoning-heavy tasks, making it a serious assistant for research, automation logic, and agent decision-making.

🎨 Where GPT-4.1 Still Holds the Crown

OpenAI’s GPT-4.1 isn’t obsolete—far from it. In fact, it shines in areas where Claude still hasn’t stepped in:

Image generation with DALL·E 3 is seamless inside ChatGPT.
Plugin ecosystem, custom GPTs, and cross-platform availability (web, mobile apps, API) make GPT-4.1 more flexible for creative and hybrid workflows.
Its UI and user experience are polished and intuitive for both newbies and pros.
