DeepSeek has released DeepSeek-V4-Flash-0731, a 304-billion-parameter model that supersedes its earlier preview version with what the company describes as substantially enhanced agentic capabilities. According to DeepSeek's technical report, the model outperforms the larger DeepSeek-V4-Pro (Preview) on several coding and agent benchmarks despite a far smaller activated parameter count.

Z.ai released GLM-5.2 on June 16, 2026, the first open-weight model to match proprietary models like Claude Opus 4.8 on agent benchmarks. The MIT-licensed model closes the performance gap to 6.8 months behind frontier labs, down from expected 9+ months as compute scales.
