Three DeepSeek V5 model identifiers have appeared in the company’s official Harness repository on GitHub, drawing attention to its next-generation model development. The identifiers—deepseek-v5, deepseek-v5-open, and deepseek-v5-next—appear in tests for the software’s DeepSeek account integration.
The tests examine how the client handles model compatibility, including which models appear in its available-model list and when a client upgrade is required. One test allows the deepseek-v5-open entry to appear alongside DeepSeek Flash, while other entries trigger compatibility-related responses.
The code provides an early look at V5 naming within DeepSeek’s development tools. The entries are part of test scenarios and contain no model specifications, benchmark results, or release schedule. [DeepSeek]
