DeepSeek's Claude Code is set to undergo public testing today and will be released alongside V4-Pro.

According to Dongcha Beating monitoring, DeepSeek's self-developed Harness is also on the way. A leaked screenshot from the DSH official beta test group indicates that the team plans to release the DSH public beta on August 13.

DSH is a Claude Code competitor being developed by DeepSeek. Earlier reports suggested that DSH would be released alongside V4-Pro.

The model version in DeepSeek's official API documentation has now been updated to DeepSeek-V4-Pro-0813, aligning perfectly with the timeline on both sides.
