We are excited to announce **GLM-5.2** on Workers AI, Z.ai's flagship agentic coding model.

[`@cf/zai-org/glm-5.2`](https://developers.cloudflare.com/workers-ai/models/glm-5.2/) is a text generation model built for agentic coding workflows. With function calling and reasoning support, it can handle long codebases, multi-step planning, and tool-augmented agents.

**Key features and use cases:**

- **Agentic coding**: Designed for autonomous coding tasks, long-horizon planning, and complex software engineering workflows
- **Large context window**: GLM-5.2 supports up to a 1,048,576 token context window. Workers AI is launching the model with a 262,144 token context window and plans to increase this in the future
- **Function calling**: Build agents that invoke tools and APIs across multiple conversation turns
- **Reasoning**: Tackles complex problem-solving and step-by-step reasoning tasks

Use GLM-5.2 through the [Workers AI binding](https://developers.cloudflare.com/workers-ai/configuration/bindings/) (`env.AI.run()`), the REST API at `/run` or `/v1/chat/completions`, or [AI Gateway](https://developers.cloudflare.com/ai-gateway/).

Pricing is available on the [model page](https://developers.cloudflare.com/workers-ai/models/glm-5.2/) or [pricing page](https://developers.cloudflare.com/workers-ai/platform/pricing/).
