Anthropic Just Dropped Claude Opus 4.8 (overhyped?)
⏱ 8 min video · 2 min read28 May 2026
TL;DR
Anthropic released Claude Opus 4.8, a modest incremental update to Opus 4.7. The creator breaks down the key changes without hype: same pricing, new effort control modes in Claude.ai, improved honesty, and a preview of the upcoming Claude Mythos model.
Key points
1
Claude Opus 4.8 is available now across Claude.ai, Claude desktop app, Claude Code, and the API — pricing unchanged at $5/million input tokens and $25/million output tokens.
2
New effort control modes (Low, Medium, High, Extra, Max) are now available in Claude.ai and Claude Co-work, not just Claude Code — defaults to High effort.
3
Anthropic identifies improved honesty as the headline improvement: Opus 4.8 is reportedly more likely to flag uncertainties and less likely to make unsupported claims.
4
Dynamic Workflows (research preview) lets Claude run hundreds of parallel sub-agents in a single Claude Code session — only relevant to Claude Code users.
5
Anthropic teased Claude Mythos, described as a higher-intelligence model class currently in limited Fortune 500 testing, expected to release within weeks.
Actionable insights
→
If you use Claude.ai or Claude Co-work, you can now manually select effort levels — drop to Low or Medium for simple tasks to reduce token usage.
→
Do not expect a dramatic capability jump from Opus 4.7 to 4.8 — Anthropic itself calls it a modest but tangible improvement, so hold your bigger expectations for Claude Mythos.
→
Claude Code users get two new features worth testing: Extra High effort mode and Dynamic Workflows for running parallel sub-agents on complex projects.
Notable quotes
“When they are coming out and saying this is just a modest update, I'm not expecting this to be a huge leap in capabilities.”
“Claude Mythos — this is the AI model that apparently is too good for them to release to the public.”
“I'm not going to sit here and hype this up.”
