Strengths

✓

Latest Z.ai flagship

GLM 5.2 is Z.ai's newest top model, leading the GLM line on agentic, reasoning, and coding capability.

✓

1M token context

A 1,048,576-token context window lets GLM 5.2 reason over very large codebases and document sets in one request, with up to 32,768 output tokens.

✓

Strong agentic & coding

Tuned for tool-use and multi-step agent workflows, it plans, calls tools, and writes code reliably across long task chains.

✓

Great value

At $1.96 per 1M input and $6.16 per 1M output tokens, it offers flagship agentic and coding performance below the cost of comparable Western frontier models.

GLM 5.2 API: Z.ai's flagship for agentic and coding work

GLM 5.2 is Z.ai's latest flagship model, built for agentic workflows, strong reasoning, and coding, with a million-token context window.

On YepAPI you call GLM 5.2 through a single OpenAI-compatible endpoint at $1.96 per 1M input and $6.16 per 1M output tokens, with a 1,048,576-token context window.

What is GLM 5.2?

GLM 5.2 is the top model in Z.ai's GLM family, the latest in a line that has built a reputation for agentic capability. It is tuned for the demands of autonomous agents: planning multi-step tasks, calling tools in sequence, and writing and revising code across long chains of work. It carries a 1,048,576-token context window and up to 32,768 output tokens, enough to keep large codebases or long task histories in view while it reasons. GLM 5.2 competes with frontier Western models on agentic and coding benchmarks while pricing below them, which has made the GLM line a popular value choice for builders of coding assistants and agents.

Build with GLM 5.2 via YepAPI

Call GLM 5.2 through YepAPI's OpenAI-compatible /v1/ai/chat endpoint. Point your OpenAI SDK at YepAPI and set the model string to glm-5.2; switching to another model later is a one-string edit. A single YepAPI key also reaches every other model plus SEO, SERP, and web-scraping tools, which pairs naturally with GLM 5.2's agentic strength: an agent can scrape and search the web through the same key it uses for reasoning, all on one integration.

GLM 5.2 API pricing — $1.96 / $6.16 per 1M tokens

GLM 5.2 costs $1.96 per 1M input tokens and $6.16 per 1M output tokens on YepAPI. For a flagship-class agentic and coding model with a million-token window, that undercuts comparable Western frontier pricing, which is GLM's core appeal. Agentic workloads can be token-heavy, so the value gap compounds across long tool-using runs, and your key lets you route cheaper sub-steps to smaller models to manage cost.

GLM 5.2 for agents and coding assistants

GLM 5.2 is built for autonomous agents and coding tools: planning and executing multi-step research, orchestrating tool calls, and generating, debugging, and refactoring code across a large repository. The million-token context lets it hold an entire codebase or a long agent trajectory in memory, and its strong tool-use behavior keeps long task chains on track. When you want frontier-grade agentic performance without frontier pricing, GLM 5.2 is a leading option.
