Eve agents on [Vercel](<https://creatorstoolbox.com/tools/vercel>) get free access to [GLM 5.2](<https://vercel.com/changelog/glm-5-2-free-for-eve-agents-through-august-27-via-blackbox-on-ai-gateway>), Z.ai's open-weights coding model with a 1M-token context window, through August 27. The model is served by Blackbox AI on AI Gateway, and new eve agents now use it as their default.

- Create a new agent with GLM 5.2 preset using npx eve@latest init my-agent.

- Switch an existing agent by setting model: "zai/glm-5.2" in agent/agent.ts, or by running eve set --model zai/glm-5.2 from the CLI.

- The free offer does not cover Fast mode or the zai/glm-5.2-fast variant.

- After August 27, GLM 5.2 stays available on AI Gateway at standard provider rates.
