Rumours & leaks
None of this is confirmed by Anthropic. We're reporting the chatter so you can judge it — not presenting it as fact.
A model labelled “Claude Honeycomb EAP” briefly appeared in Cursor on July 9, 2026. Community watchers widely read it as an early Opus 5 preview — but the name was never confirmed as Opus 5.
Leak aggregators point to a launch somewhere between mid-July and early August 2026; some posts name July 20–21. None of this is on Anthropic's calendar publicly.
Community leaks describe a 1M-token context window and an “xhigh” reasoning-effort setting — both already present on the shipped Opus 4.7/4.8 line, so treat these as extrapolation, not new information.
Treat every number and date above as unverified. Leaked specs are frequently wrong, renamed, or cancelled before launch. This page will be corrected against Anthropic's official announcement.

Don't wait for the rumour
NottoAI runs Claude Opus 4.8, Sonnet 5 and Fable 5 — Anthropic's current top models — in one chat, alongside GPT, Gemini and Kimi. Switch models mid-thread, no API key.
No. As of this page's date, Anthropic has not announced or released Claude Opus 5. The current flagship Opus model is Opus 4.8. Anything you read about Opus 5 pricing, benchmarks, or a model ID is rumour or extrapolation, not confirmed information.
There is no official release date. Community leaks have floated a mid-July to early-August 2026 window (with some posts naming July 20–21), largely off the back of a “Honeycomb” model that briefly showed up in Cursor. Anthropic has confirmed none of this. We update this page as soon as there's an official announcement.
“Claude Honeycomb EAP” was a model label that appeared briefly in Cursor in July 2026. Many observers guessed it was an early Opus 5 preview, but the connection was never officially confirmed. It may be Opus 5, a smaller research build, or something else entirely.
Yes. NottoAI already runs Claude Opus 4.8, Claude Sonnet 5, and Claude Fable 5 in one chat — no API key needed. If and when Opus 5 launches, we add it fast, and you'll be able to switch to it in the same model picker.
Start on the current Claude flagship today. If Opus 5 ships, we'll add it fast — and you'll switch to it in the same model picker.
