An early-access review of Claude Opus 4.8 tests coding, design, and strategy tasks using Claude Code and Claude Cowork. It highlights strengths in greenfield prototyping, one-shot features, and fast execution, notes the last-10% edge cases and hallucinations, and introduces new dynamic workflows with parallel subagents and adjustable effort control. It also contrasts Opus 4.8 with 4.7 for data-heavy strategy and roadmap work.
Key Takeaways
- Opus 4.8 excels at greenfield prototyping, one-shot features, and fast execution.
- It struggles with the last 10% of tasks, edge cases in existing codebases, and hallucinations.
- New features include dynamic workflows with parallel subagents and adjustable effort control in Claude.ai and Cowork.
- Opus 4.7 remains preferable for data-heavy strategy and roadmap work, while 4.8 shines for coding, design, and business strategy testing.
Excerpt
I got a few hours of early-access testing with Anthropic’s newly released model Opus 4.8. I walk through real coding, design, and strategy tasks across Claude Code and Claude Cowork, and give you my unfiltered view on what impressed me and what didn’t. Listen or watch on YouTube , Spotify , or Apple Podcasts What you’ll learn: Where Opus 4.8 excels: greenfield prototypes, one-shot features, and fast execution Where it struggles: the last 10%, edge cases in existing codebases, and hallucinations How Opus 4.8 compares to Opus 4.7 on business strategy work Why I’m still reaching for Opus 4.7 on…
