  "title": "GLM 5.2 free for eve agents through August 27 via Blackbox on AI Gateway",
  "why_included": "Eve agents can use GLM 5.2 free through August 27 via Vercel AI Gateway; new agents default to it, while existing agents need a model-setting change.",
  "summary": "Z.ai’s open-weights **GLM 5.2** has a **1M-token context window** and is free for eve agents through **August 27** via Blackbox AI on Vercel AI Gateway. New eve agents use it by default.",
  "practical_implication": "Builders can initialize a new agent with npx eve@latest init my-agent. Existing agents can switch in agent/agent.ts or through eve set, making the promotion useful for a bounded model evaluation.",
  "agent_context": "Z.ai’s open-weights **GLM 5.2** has a **1M-token context window** and is free for eve agents through **August 27** via Blackbox AI on Vercel AI Gateway. New eve agents use it by default.\n\nBuilders can initialize a new agent with npx eve@latest init my-agent. Existing agents can switch in agent/agent.ts or through eve set, making the promotion useful for a bounded model evaluation.\n\nThe offer excludes **Fast mode and zai/glm-5.2-fast**. After August 27, standard provider rates apply, and the material provides no performance or quality measurements.",

  "connected_context": {
    "meaning": "This turns GLM 5.2 into a bounded, nearly frictionless eve evaluation rather than evidence for adopting it: new agents default automatically, existing ones can switch explicitly, and the free period ends quickly. Its 1M-token context expands the test envelope, but Fast mode is excluded and no quality, latency, or reliability result supports replacement decisions.",

        "reason": "The gateway can express a general preference for fast serving, but this promotion explicitly excludes GLM 5.2 Fast, demonstrating that fast-mode policy does not make every discounted or free route eligible."
