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.
