GoKawiilAnthropic is now rolling out Sonnet 5, and it's almost as good as the Opus range, but it is designed to be cheaper than the company's flagship model.
In a blog post, Anthropic said Claude Sonnet 5 is "built to be the most agentic Sonnet model yet," and added that it comes with advanced features, such as the ability to make plans and use tools like browsers and terminals.
Previously, these features were mostly locked to Opus 4.8, but now Sonnet 5 can do almost everything the flagship model can.
According to Anthropic, Sonnet 5 is a big upgrade, especially for those who rely on Claude for coding, research, automation, document work, and other multi-step tasks.
"Sonnet 5 narrows the gap," Anthropic said, confirming the new model is a step closer to the expensive Opus 4.8 model.
Claude Sonnet 5 is designed for more agentic work
I personally found the Sonnet 5 experience similar to Opus, which means it's better at creating plans or calling tools, and it's also surprisingly good at verifying its own work.
In other words, it handles "Can you fix your code?" queries much better, almost closer to Opus.
