  "account": "After gaining initial traction last week with unprecedented cyber capabilities, GLM-5.3, the open-source language model from Chinese startup z.ai, has now expanded its reach by integrating into the application programming interface (API). This development allows developers to seamlessly incorporate the model into their applications, agents, and projects. Current subscribers of GLM Coding Plans can only utilize the OpenAI Chat Completions-compatible protocol. Z.ai aims to release the model's weights publicly, yet release dates and licensing specifics remain uncertain. API pricing remains unchanged from GLM-5.2 at $1.40 per million input tokens and $4.40 per million output tokens. Developers can also benefit from cached input, which is currently free for a limited time, with a cost of $0.26 per million tokens for cached storage. Facing competition from other high-end frontier APIs, GLM-5.3 offers an affordable entry point for developers looking to test advanced coding and long-horizon agent performance, even if its cost per task is marginally higher due to its increased verbosity.",
  "summary": "After a stunning debut last week with cyber capabilities so advanced they reportedly found a previously undetected vulnerability in Cursor, GLM-5.3, the new frontier open source language model from Chinese startup z.ai, has now hit the application programming interface (API) — allowing developers the ability to build atop it and plug it into their agents and applications.
