GLM-4-long - A 2 million-word long text model launched by Zhipu AI (API now open)

What is GLM-4-long?

GLM-4-long is a 2 million-word long text model launched by Zhipu AI, and its API is now available for use on Zhipu AI's open platform BigModel. It supports ultra-long input and is designed to handle ultra-long text and memory-based tasks. The maximum context length is 1M, approximately 1.5-2 million words, equivalent to two copies of Dream of the Red Chamber or 125 academic papers.

Main functions of GLM-4-long

• Ultra-long text processing capabilitiesGLM-4-long supports context lengths up to 1M (approximately 1.5-2 million characters), equivalent to the capacity of about two volumes of "Dream of the Red Chamber" or 125 academic papers, and can handle very long text data.
• reasoning abilityGLM-4-long can perform complex reasoning tasks, such as inserting language fragments into long texts and making inferences and decisions based on these fragments.
• Key technical pointsThe development team of GLM-4-long adopted some key technologies, such as progressively expanding the context length of the model, training it step by step from 4096 to 1M, and using batch sorting methods and instructions to synthesize data to improve training efficiency.
• Performance indicatorsThe initial response time is approximately 50 seconds when inputting 500,000 characters, approximately 140 seconds when inputting 1,000,000 characters, and approximately 280 seconds when inputting 1,500,000 characters.
