According to a screenshot circulating on social media, as reported by X platform blogger @MaxForAI, the DeepSeek Harness plans to start internal testing later this week, with the first batch of users selected from small group chats. Selected individuals must submit personal information and sign a "Confidentiality Commitment Letter." The screenshot specifically reminds that any leaks will result in disqualification and affect future opportunities for selection in the DeepSeek model and product internal testing. If the news is true, the official version of DeepSeek V4 and the Harness product are expected to be launched soon.
