glm-5.2 — API, Pricing & Context Window | Vivgrid
glm-5.2 on Vivgrid: Zhipu AI's coding model with a 1M-token context window, function calling, and competitive pricing.
glm-5.2 is Zhipu AI's latest coding and reasoning model, pairing reliable function calling with a major upgrade: a 1M-token context window, up from 200K in glm-5.1. It's a strong, low-cost option for agentic coding workloads that need to reason over large codebases.
On Vivgrid, glm-5.2 is reachable through the unified, OpenAI-compatible endpoint, so it integrates cleanly alongside models from OpenAI, Anthropic, Google, and DeepSeek under one API key.

Pricing
Pricing in USD per 1M tokens, matching the provider's rates.
| Input | Cached input | Output |
|---|---|---|
| $1.20 | $0.30 | $4.20 |
What one request costs
The rates above applied to a 20K-token prompt with a 2K-token reply — a typical single agent turn, small enough that every request is billed at the base rate.
| Request | Cost |
|---|---|
| Cold prompt, nothing cached | $0.0324 |
| Warm prompt, 90% of the input served from cache | $0.0162 |
API surfaces
The Vivgrid Console catalogs glm-5.2 on one surface, all behind the same API key. The endpoint shown is the one the Console previews for that surface.
| Surface | Primary endpoint | Use it for |
|---|---|---|
| Vibe coding | /chat/completions | Coding CLIs and IDE agents that drive the model themselves — point the tool at Vivgrid and keep your own loop. |
