Opus 4.8

NVIDIA and Microsoft birthed a new computer

Jun 02, 2026

Hey folks,

I’m spending as much time as possible off Twitter, and any other general doomscroll distractions. I’ve got work to do (the course/manual/whatever it’ll be called).

Aiming to get at least the preview ‘lessons’ out this month.

I’m not going to force any wisdom out in today’s intro because it’s not my style.

On to the condensed version of the AI madness…

Headlines

Claude Opus 4.8 is out, with dynamic workflows in Claude Code. Claude now writes an orchestration script, then spins up subagents in parallel to work through complex tasks.
- Dex’s take: this doesn’t prove loose multi-agent systems work. Deterministic workflows around small agent loops are more reliable.
- Claude Opus 4.8 - Simon Willison calls it a modest but useful upgrade, mostly because it’s more honest about uncertainty and less likely to miss flaws in its own code. Every’s vibe check is more bullish: they found it a big jump from 4.7, strong at coding/writing/knowledge work, and competitive with GPT-5.5 on their internal senior-engineer benchmark. The catch is the harness: the model is back, but Claude’s app still feels messier than Codex.
  - Scores top on ARC-AGI-3, tripling 5.5’s score
  - Datacurve’s new benchmark places it below gpt 5.5 and only marginally better than 5.4. Using a lot more tokens…$$$.
