Anthropic is reportedly planning to launch Claude Opus 5 later this week, a move that would represent the company’s most aggressive response yet to OpenAI’s recently launched GPT-5.6. There is no official confirmation from Anthropic, and the company has not issued any official statement as of July 14. Anthropic’s latest publicly available model is Claude Opus 4.8, which launched on May 28, 2026, followed by Claude Fable 5 on June 9 and Claude Sonnet 5 on June 30. Unverified reports reference a model codenamed “Honeycomb” that may preview Opus 5 capabilities, with a rumored context window of up to 1 million tokens. Community forecasters have been pointing to Q3 2026 as a likely window for an Opus-tier release. If Opus 5 launches this week, benchmark comparisons against GPT-5.6 will be closely watched.
