AI Agents Just Changed Forever: GLM 5.2 The Best Open-Source Model Ever?

TL;DR

• 1

  GLM 5.2 is the open model Riley thinks is finally real: He says Z.ai's model is far cheaper than GPT 5.5, felt comparable in real use to Claude Opus 4.8 and GPT 5.5, and handled coding, research, Notion, and Slack tasks without the usual benchmark hype letdown.

  You can add GLM 5.2 to Cursor in 3 to 5 minutes with OpenRouter: Riley shows a simple setup by overriding the OpenAI base URL, pasting an OpenRouter key, and adding the custom model z-ai/glm-5.2 so it works directly inside Cursor agent sessions.

  Codex can now turn a screen recording into a reusable skill: Using the new record and replay plugin, Riley records a Typefully draft workflow, and Codex converts that recording into a callable skill that later tries to upload a video draft automatically.

  SpaceX buying Cursor matters because of resources, not headlines: Riley's take is practical. The reported $60 billion deal could give Cursor more compute, more capital, stronger distribution through Elon Musk's network, and a better shot at competing with Codex and Claude.

• 5

  People are in a real 'Fable depression' after Anthropic pulled the model: Riley says users who briefly had Fable access now find Opus 4.8 and GPT 5.5 less ambitious by comparison, and he frames the strongest benchmark as whether a model keeps attacking hard problems instead of backing off.

  Claude's newer features point toward agent-native mini apps: He highlights web-only design mode upgrades like direct canvas editing and deployment to Vercel, plus Claude Code artifacts that generate shareable interactive pages for teammates.
