Anthropic shipped Claude Opus 4.8 yesterday. It catches 4x more of its own code mistakes, runs hundreds of parallel subagents through Dynamic Workflows, and keeps the same price as 4.7. Here is what genuinely changed and whether it is worth switching.

Claude Opus 4.8 is available now in GitLab Duo Agent Platform — built for complex multi-step agent work with less mid-run disruption.

Anthropic's latest flagship AI model Claude Opus 4.8 arrives with sharper reasoning, tighter alignment, and a price tag that hasn't budged.

A Mythos-class model is expected in the coming weeks.
