Reports claim Anthropic testing Opus 5.5 model ahead of Tuesday release

**Summary**

Users on Reddit are discussing claims that Anthropic is conducting stealth testing of a new model variant called Opus 5.5, allegedly operating under the internal codename `claude-wafer-eap`, with speculation that a release is planned for Tuesday. The claim appears to originate from r/ClaudeCode.

**Dominant framing**

The posts frame this as leaked or discovered information about unreleased Anthropic technology. The repeated posting of the same claim across multiple threads suggests users treating it as noteworthy insider knowledge about upcoming product releases.

**Notable context**

Engagement is minimal—the highest-scoring post has only 2 comments, and most variants have 0-2 comments. No mainstream media coverage exists. The claim relies entirely on Reddit discussion with no cited sources, official announcements, or verification from Anthropic. Users are not visibly debating the claim's credibility or providing corroborating evidence; they are primarily repeating it. The specificity of the codename and release date suggests either genuine leaked information or plausible-sounding speculation presented as fact.
