GLM 5.2 free for eve agents through August 27 via Blackbox on AI Gateway

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.

Source 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.

The 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 · Feed7 Judgment

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.

GPT-5.6 Sol is 50% off on AI Gateway for the next monthBoth are temporary gateway evaluation incentives, but GLM is free only for eve through August 27 while GPT-5.6 Sol is discounted across gateway tiers through September 18.Gemini 3.7 Flash now available on AI Gateway for 50% offGemini’s longer discount and integrations across several coding agents contrast with GLM’s shorter, eve-specific promotion, making the latter better suited to a tightly bounded trial.AI Gateway adds unified fast mode supportThe 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.Qwen 3.8 Max now available on Vercel AI GatewayQwen provides another long-context gateway candidate, reinforcing that context size alone cannot select a model; GLM’s free window should be used for comparative workload testing rather than specification-based adoption.
