Been building niche AI models for the last year — fine-tuned classifiers, small specialized LLM wrappers, a couple of vision models. Selling them was always the hard part, not the building.

Discord servers get you scammed on payment. Twitter DMs get you ghosted after you send the API key. Cold outreach converts at basically 0%. There was no actual marketplace for this — just scattered communities and vibes-based trust.

So I built Bin Bag: a place where AI developers list their models with real pricing and real checkout (Whop handles the payment infra, so no more "let me Venmo you" awkwardness), buyers can actually vet you before paying, and there's a live chat to ask the seller technical questions before committing.

If you're building models and tired of monetizing them through screenshots and DMs, or if you're hunting for a specific fine-tuned model instead of building it yourself from scratch — this is worth a look.

Open to feedback from anyone who's tried to sell AI tools before. What's been your biggest blocker — trust, discovery, or payment friction?
