Battle-test AI coding models side by side
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.
Free GLM-powered assistant that turns prompts into slides, sites and code
Describe your topic and Z.ai drafts a slide deck with structured layouts, headings and visual placeholders you can refine with follow-up prompts.
Paste a brief or a bug report and it will produce code in common languages, and it can scaffold functioning web pages and small full-stack apps.
Chat, brainstorming, rewriting, translation and summarising all run through the same prompt box, with GLM Flash models keeping responses quick.
Ask a question and it can ground the answer in web sources rather than relying only on its training data, useful for current facts and comparisons.
Provides industry-leading reasoning, coding, and multimodal features, but lacks dedicated automated slide and document generators.
