GLM 4.5 excels in reasoning and quick text responses.

Input: text Output: text Context: 131,072 tokens Release: 2025-07-25

Z.AI's GLM 4.5, released on July 25, 2025, is designed for agent-based applications. With a context window of 128k tokens, it excels in text-to-text tasks. The model features a Mixture-of-Experts architecture, enhancing reasoning, code generation, and agent alignment. It offers hybrid inference modes, allowing users to switch between 'thinking' for complex reasoning and 'non-thinking' for quick responses. Control the reasoning behavior with the 'reasoning' parameter. This flexibility makes GLM 4.5 suitable for diverse applications where reasoning and quick response are essential.

Prompt:

Write 150 words on how AI might positively upend work, leisure and creativity

AI promises to positively upend the very fabric of our lives, transforming work, leisure, and creativity. In the workplace, it will act as a powerful co-pilot, automating tedious tasks and augmenting human intelligence. This will free us from drudgery, allowing us to focus on strategic thinking, complex problem-solving, and meaningful collaboration, fundamentally shifting our value from execution to innovation. Leisure will become profoundly personalized and immersive. AI could curate bespoke entertainment, craft unique travel experiences, and even generate interactive stories tailored to our moods. This moves us from passive consumption to active, bespoke engagement. Creativity will be supercharged as AI becomes a collaborative partner. Artists can use it to explore novel aesthetics, musicians to compose intricate scores, and writers to overcome creative blocks. By handling technical execution, AI empowers us to focus on the core of creativity: the spark of a new idea, pushing the boundaries of human imagination further than ever before.

up.end

/ˌəpˈend/

verb

To “upend” means to completely disrupt, overturn, or drastically change the established order or structure of something. It implies a significant shift or alteration that can potentially have far-reaching consequences. When something is upended, it is turned upside down or transformed in a way that challenges conventional norms or expectations. The term often carries a sense of innovation, transformation, and sometimes even a hint of upheaval, indicating that the changes are not just minor adjustments but rather a fundamental reimagining of the status quo.
