Anthropic appears to be routing some Opus 5.5 traffic to an unreleased next-generation checkpoint in live testing (report)

Verified (fact)

AI Times reported this, citing TestingCatalog and other sources. There are signs that Anthropic is testing an unreleased next-generation checkpoint by routing part of the traffic for its top model, Opus 5.5, to it. The method is reportedly shadow deployment or A/B testing. There has been no official release or announcement yet.

Needs fact-check (claim)

Developers and testers are reportedly saying it "surpasses Opus 5.5." These are not official Anthropic figures.

Why it matters (interpretation)

This signals that a successor to Opus 5.5 is being tested in a live service environment, and a release may be near. For now, however, the evidence rests only on user observations.
