We also shipped dynamic workflows in Claude Code (research preview), for tasks too big for one pass. Make sure to default to auto mode so Claude isn't stopping for permissions. It's token-intensive, so save it for your biggest jobs: migrations, refactors, perf optimization,

Claude 4.8 Defaults to High Effort, Improved Coding Performance
By
–
4.8 defaults to high effort, which spends about the same tokens as 4.7's default on coding but performs better. For hard problems and long-running async work, switch to xhigh. We've raised Claude Code rate limits to cover the extra tokens.

Claude Opus 4.8 Released: Stronger Coding Model with Benchmarks
By
–
Claude Opus 4.8 is out today. It's our strongest coding model yet: up on SWE-bench Pro (from 64.3 to 69.2) and noticeably more honest about its own work. It tells you when it's unsure and catches its own bugs instead of declaring victory early. Same price as 4.7.

Claude Code User Shares Experience with Opus 4.8 Fast Mode
By
–
Fast mode for Opus 4.8 is much more affordable now. Try it out in Claude Code, I've found it changes how I use Claude. Fast mode for interactive work where I want rapid responses, normal mode for longer async tasks where I don't need results right away.

ANTHROPIC ACABA DE LANZAR CLAUDE OPUS 4.8
— Nico (@nicos_ai) 28 mai 2026
Y puede que sea su mejor modelo hasta la fecha:
→ 2.5x más rápido y 3x más barato con modo /fast
→ Trabaja SOLO como un ingeniero senior, sin que lo supervises
→ Lanza cientos de subagentes en paralelo para completar tareas complejas… https://t.co/QSIQ1rvfpo pic.twitter.com/2cNoRMTRDgANTHROPIC JUST RELEASED CLAUDE OPUS 4.8 And it might just be their best model to date: → 2.5x faster and 3x cheaper with /fast mode
→ Works ONLY like a senior engineer, no supervision needed
→ Launches hundreds of subagents in parallel to handle complex tasks on its own And -
User compares AI model 4.8 to 4.6, highlighting collaboration strengths

„4.8 understands nuances better, feels much more natural to talk to, and is overall a stronger collaborator on everything from coding to knowledge work.“ So big. Is 4.8 being our good old friend 4.6 just better?? Testing time

Opus 4.8 AI Model Release: Agentic Coding Boost, Faster, Cheaper Modes
By
–

Opus 4.8 is live. Benchmarks especially significant jump in Agentic coding, but more important: „Fast mode is available for Opus 4.8. It's the same model at roughly 2.5x the speed, and we've made it three times cheaper than before.“
