The tweaks to Sonnet 4.6 have taken it past the pricier Opus 4.6 in two of 13 benchmark categories: agentic financial analysis (Finance Agent v1.1, 63.3 percent vs. 60.1 percent) and office tasks (GDPVal-AA Elo, 1633 vs. 1606). Opus 4.6 wins in six of the 13 categories, in tests that show rival Gemini 3 Pro and GPT-5.2 each leading in 2 of 13 categories. But benchmark tests should not be taken too seriously.

There is a plague in software development as of today, and it has become something we are gradually beginning to accept. It goes something like this: you're stuck on some code, so you deliver a code snippet to your favorite AI tool, hoping to debug it. You might get a solution, but then your AI tool introduces a new bug, which you suddenly have to spend time debugging.

The V3.1 has a longer context window, meaning it can consider a larger amount of information for any given query, allowing for longer conversations with better recall.
