Story

Z.ai's GLM-5.2 (1M context, big coding and agentic gains) is landing in agent stacks within days of release, MiniMax M3 is ranking as a top open coding model, and Kimi K2.7 Code HighSpeed claims ~6x faster multimodal coding inference (Kingy AI). The reference point stays DeepSeek V4-Pro (1.6T total / 49B active), the first open weight within striking distance of Opus 4.7 and GPT-5.5 on real coding while costing roughly 34x less per output token. For solo builders, that cost-per-token gap makes self-hosted or routed open models viable for agentic loops that were API-only six months ago.
