[Rumor: DeepSeek Harness to Begin Beta Testing This Week, Competing with Claude Code] BlockBeats News, July 28: According to a leak from Max For AI, a DeepSeek version of Claude Code named 'Harness' is set to begin beta testing soon. Screenshots of the beta recruitment circulating in the community indicate that DeepSeek Harness plans to launch its beta test later this week, with the first batch of users selected from small group chats. Selected participants will need to submit personal information, sign a 'Confidentiality Agreement,' and gain access to the product. Notably, the screenshots explicitly warn that any leaks will result in disqualification and may impact eligibility for future DeepSeek model and product beta tests, as well as collaboration opportunities. If the rumors are true, the official V4 version and Harness will be announced soon. Beating reported earlier that the official DeepSeek V4 version (V4 GA) might be delayed until mid-August. After the closed beta for Harness ends, V4 is expected to be released within 1 to 2 weeks, likely between August 10 and August 20. If the rumors are accurate, DeepSeek V4's launch may face stronger competition, as next-generation models like GPT-6, Claude Fable 5.1, and GLM-5.5 may already be entering the market.
