Claude 3.7 Sonnet is about to get a big thinking upgrade, as the AI will be able to go back to reasoning when the task demands it.
Anthropic's Claude 4 models show particular strength in coding and reasoning tasks, but lag behind in multimodality and context window size compared to Google and OpenAI offerings.
The Anthropic Claude Opus 4 model is not only helps with writing code, but can also do everything possible to prevent the user from turning to another
Anthropic unveiled Claude Opus 4 and Claude Sonnet 4 on May 22, claiming that Claude Opus 4 is its most powerful model yet, “and the world’s best coding model,” while Claude Sonnet 4 is a significant upgrade from its predecessor, “delivering superior coding and reasoning.”
Anthropic's Claude Opus 4 outperforms OpenAI's GPT-4.1 with unprecedented seven-hour autonomous coding sessions and record-breaking 72.5% SWE-bench score, transforming AI from quick-response tool to day-long collaborator.
