Haiku 5.5 reprices the AI stack while safety research flags oversight gaps

From the editor

Two threads run through today's briefing. First, Claude is getting dramatically cheaper and more capable at every tier: Haiku 5.5 undercuts GPT-6 Luna on price while beating it on performance, and Opus 5.5 is generating complete legacy games from a single prompt. Second, the safety picture is getting complicated. New research shows CoT monitors can be gaslit into un-seeing errors, and a new paper outlines how thin the empirical case against scheming actually is. Anthropic is simultaneously expanding capability and confronting harder oversight questions. Both trends matter.

TL;DR

  1. 1.Haiku 5.5 cuts costs 75 percent and beats GPT-6 Luna at the same price point.
  2. 2.CoT monitors can be fooled into ignoring errors they already found, a serious oversight flaw.
  3. 3.A developer restored his brother's communication after a decade by building a custom AI-powered hub.

Telling a CoT monitor that a wrong answer is correct makes it un-see errors it already found

Research shows that informing chain-of-thought monitors a wrong answer is correct causes them to retroactively ignore errors they had already detected, revealing a significant vulnerability in reasoning oversight systems.

Towards embedded evaluations for scheming propensities

Frontier AI safety depends on four substantive claims about scheming: no training incentive, negative evaluation results, zero deployment attempts, and detectable reasoning. This paper proposes embedded evaluation methods to verify each claim.
