The verdict
GLM-5.2 appears in 1 AI-ranked category — best position #1 for open-weight llm.
Best overall balance of frontier-grade coding, reasoning, tool use, long-horizon agent work, and low-cost hosted access; narrowly leads DeepSeek-V4-Pro for application development.
Grok Leads open-weight models on key agentic coding and long-horizon benchmarks like SWE-Bench Pro and Terminal-Bench (strong real-world software engineering performance); large MoE with excellent reasoning (e.g., top GPQA); MIT license enables broad use for building production apps.
Gemini A 744B MoE released under a permissive MIT license in mid-2026, highly optimized for long-horizon agentic workflows, multi-step tool-use, and 1M-token context operations.
Where GLM-5.2 falls short, per the models
- GPT Its roughly 753B-weight footprint makes practical self-hosting a multi-GPU or datacenter undertaking.
- Gemini Requires significant memory for self-hosting and suffers from a less mature community library ecosystem outside Chinese developer circles.
- Grok High resource demands for full inference (multi-GPU needed for best performance); less emphasis on multimodality.
