Best open-model directory: Hugging Face model hub. Hugging Face catalog of models, datasets, and demos. Use it when you need to discover open models and inspect practical metadata.
Best multi-provider model directory: OpenRouter models guide. OpenRouter catalog for comparing model providers and capabilities. Use it when you need a broad model market view before testing.
Best practitioner discovery feed: AI Engineer Talks. Conference talks from builders working on the current AI stack. Use it to find practical talks and people worth following.
Directories are starting points, not answers
AI directories help with discovery, but they can become stale fast. Use them to find candidates, then verify each resource through official docs, current examples, and your own tests.
Hugging Face is strongest for open models. OpenRouter is useful for model comparison. AI Engineer talks are good for finding practitioners and current themes.
How to avoid shallow discovery
A good discovery process asks what problem you are solving before browsing. Otherwise every new tool looks useful and none of them change your work.
Save resources only when they answer a current question: what to learn, what to build, what to compare, or what to verify. That keeps discovery from turning into procrastination.
