The list
Each entry stays intentionally light: a date, a title, and a note on why it deserves to be remembered.
Z.ai released GLM-5.3, a post-training-driven update focused on stronger coding, longer agent tasks, and newly observed cybersecurity capabilities.
As agents enter every software environment, the missing layer is not another chat interface. It is a governed way for people and agents to collect, review, transfer, and reuse knowledge through real work.
A new milestone in models. The question to revisit later: did it transform long-horizon agent work, or only improve benchmark scores?
Kimi released its 2.8-trillion-parameter K3 model with native vision, a one-million-token context window, and a focus on long-horizon coding and knowledge work.
Z.ai released GLM-5.2 for long-horizon tasks, pairing a one-million-token context window with stronger project-scale coding and sustained agent execution.
Agentic AI matters not simply because it makes software more intelligent, but because it turns the ability to operate on knowledge—once supplied only by people—into a productive input that can be called, organized, verified, and continuously improved.
