I asked multiple coding agents and models to build the same app: Create a single-page web app at index.html that beautifully renders a GitHub user profile and activity comprehensively. Pick the ID in the URL ?id=…, default to ?id=torvalds. … and compared their quality, cost, and speed. My observations: Quality variance is the highest. Some models / agents produce great visuals, some average, some fail completely. Cost and time variance are lower among the successful models. About 2X variance in each. ...

Ever since it was released, it’s been the most realistic model I’ve used. I’ve been using it to imagine characters and scenes from The Way of Kings. For example, when I wanted to visualize Helaran’s first appearance, I just quoted the description: ...

Which is the most neurotic / emotional #LLM? I ran the Big 5 personality test on a bunch of LLMs (for my TEDx MDI Gurgaon talk in August.) Here are the results. https://sanand0.github.io/llmpersonality/ Claude 3 Haiku and Llama 3 8b consider themselves the most emotional models. In fact, some of Llama 3 8b’s quotes are hilarious: Get stressed out easily. - 4. Moderately Accurate (I can get stressed, but I’m working on managing my stress levels) ...
