AI Tool Profile
Z.ai (GLM)
Z.ai offers the GLM model family through a chat app and a developer API billed per million tokens. GLM-5.3-Flash is listed at $0.15 input and $0.50 output, and the API is compatible with the OpenAI SDK.
Description of Z.ai (GLM)
Z.ai is the company behind the GLM family of language models. Its main site, z.ai, opens the Z.ai chat app, and its developer documentation describes an open platform where you register, top up a balance, create an API key and call models over a REST API. Official Python and Java SDKs are offered, and the API can also be reached through the OpenAI SDK, which makes it easier to switch existing code. The documentation lists GLM-5.3 as the latest flagship model, with improvements in software engineering and agent tasks, alongside GLM-5.3-Flash and FlashX, a multimodal coding model for visual programming, and capabilities such as thinking mode, function calling, tool streaming, structured output and context caching.
API pricing is per million tokens in US dollars. GLM-5.3-Flash costs $0.15 for input, $0.03 for cached input and $0.50 for output, GLM-5.3-FlashX costs $0.37 and $1.25, and the full GLM-5.3 and GLM-5.2 models cost $1.40 for input and $4.40 for output. Storage of cached input is listed as free for a limited time. Built-in web search costs $0.01 per use, image generation with GLM-Image is $0.015 per image, and agent products such as a slide and poster agent and a translation agent have their own rates.
Z.ai also sells a separate GLM Coding Plan subscription for use inside coding agent tools. No free API tier is stated on the pricing page, so you pay from the first token after topping up.
