Claude Opus 4.6 is now available in Windsurf, featuring notable improvements over its predecessor, Opus 4.5. This enhanced version is particularly advantageous for debugging and exploring unfamiliar codebases due to its longer thinking times, which facilitate deeper reasoning tasks. Users can experience Opus 4.6 in the Arena Mode’s Frontier Arena alongside other frontier models.
To celebrate its launch, Windsurf is offering promotional pricing for Opus 4.6. Users can earn 2x credits without the thinking mode and 3x credits with the thinking mode. Additionally, a fast mode variant of Opus 4.6 is available, delivering the same level of intelligence as the standard version but with up to 2.5 times higher output speeds. During the promotional period, which lasts until February 16, self-serve users can benefit from up to 10x credits without thinking mode and 12x credits with thinking mode.
According to Windsurf’s CEO, the Opus 4.6 iteration marks significant advancements, making it a valuable tool for tasks that require comprehensive analysis and problem-solving capabilities.
