GLM-5.2
Z.ai's 13 Jun 2026 open-weight flagship, and the model that held the top open-weight slot until Kimi K3 landed a month later. 744B MoE / ~40B active, MIT-licensed weights on Hugging Face, 1M context, 131K max output. $1.40 input / $4.40 output per 1M tokens ($0.26 cached) — a blended ~$0.90/1M. The headline result is SWE-bench Pro 62.1%, which beats GPT-5.5's 58.6%: an MIT-licensed model you can self-host outscoring a $5/$30 US flagship on agentic coding. Also the fastest of the big open MoEs at ~168 tokens/sec, roughly 2.7x Kimi K3 and DeepSeek V4 Pro. Self-hosting needs about 1TB VRAM in BF16, or ~8x H200 at FP8.
