GLM-5.3 is Z.ai's open-weight flagship model (743B parameters, 1M-token context), an incremental upgrade over GLM-5.2 with stronger coding and much better token efficiency per task. Reasoning is always on with low, high, and max effort levels (max by default), and Z.ai positions it as a top open-weight model for complex software engineering and long-horizon agent tasks.
DeepSeek V4 Pro (0813) is the August 13, 2026 general-availability checkpoint of DeepSeek V4 Pro, adding DSpark speculative decoding, reasoning-effort levels, and native OpenAI Responses API support. It is DeepSeek's flagship model for coding, reasoning, and agentic tasks in the V4 generation.
