Claude Opus 4.1 came with improvements particularly in two key areas: it significantly improved its coding capabilities, solving up to 75% of real-world programming tasks based on SWE Verified benchmarks; and the model is capable in detailed research and analysis, especially in tasks that require tracking lots of information and intelligently finding answers, according to Anthropic.
For developers, OpenAI claims GPT-5 is its most powerful coding model to date, outperforming GPT-o3 in benchmarks and real-world tasks. The model is “fine-tuned for agentic tools” like Cursor, Windsurf, Copilot, and Codex CLI, and it set new records in testing, the company stated in a blog.
According to OpenAI, GPT-5 delivers sharper reasoning, handling complex problems and multi-step instructions with greater accuracy and focus. It stays on track, follows directions more precisely, and produces more useful, reliable output, the company said.
