Anthropic Launches Claude Opus 4.8 With Gains in Coding and Honesty
Anthropic says the upgrade improves coding and reasoning scores while keeping Opus pricing unchanged and adding a preview tool for larger tasks.
On Thursday, Anthropic released Claude Opus 4.8, the newest version of its most advanced model, available globally just 41 days after the previous version.
Anthropic describes Claude Opus 4.8 as having 'sharper judgement' and increased honesty, with evaluations showing the model is around 4x less likely than its predecessor to allow unremarked code flaws.
Regular token-based pricing remains $5 per million input tokens and $25 per million output tokens, while fast mode operates at 2.5 times the speed of normal mode and is 'three times cheaper than it was for previous models.'
Alongside the model, Anthropic launched Dynamic Workflows in research preview to help manage complex tasks across hundreds of parallel subagents, with agents verifying results before reporting back.
Anthropic expects to bring Mythos-class models to all customers in the coming weeks, as the company hinted the preview period might soon end once necessary safeguards are complete.
