Show HN: Computable – Buy, sell, and redeem GPU for the exact weeks you want

A new startup called Computable is pitching a very specific dream: buy exactly the computer power you want, for exactly the weeks you want, then sell off any unused time instead of eating the cost. On paper, it sounds like airline seats for artificial intelligence training. In the comments, though, the mood was less "shut up and take my money" and more "okay, but who’s making sure this doesn’t explode?"

The biggest reaction was pure skepticism dressed up as curiosity. One commenter immediately asked the question hanging over the whole idea: if one person wants the second week of October and another wants the first week of November, who keeps this market moving? Is there some middleman stepping in, or are users just hoping the puzzle pieces magically fit? Another person went straight for the spicy stuff, bringing up an old project that reportedly ran into trouble with U.S. regulators and bluntly asking whether this whole thing looks a little too much like a financial market in disguise. That turned the vibe from startup launch to "sir, we need to see the legal paperwork."

And then came the brutally relatable internet feedback. One user said they had to log in just to look around and instantly bailed: "I walk away." Ouch. Others wondered how sellers can prove they actually own the future computer time they’re listing, while another asked the eternal startup question: how exactly are you getting paid here? So yes, the product is about renting expensive machines by the week, but the real show is the comments section demanding trust, proof, and maybe a guest checkout button.
