I gave the same prompt to GLM 5.3 Flash, Kimi K3 and DeepSeek v4 Pro and got 3 working apps back. Built all 3 inside @boltdotnew and shipped the best one to a live link. On a normal plan I'd never burn prompts on a comparison like that. Forge is an experimental mode in Bolt that runs open models with up to 50x more usage. You can build and iterate on web apps without worrying about usage limits. One monthly bar, no daily cap. Draft 10 versions if you need to, then switch to Standard or Max when it's time to ship. On Bolt's own build benchmark, the Forge models score 91% of the top paid model. Close enough for drafting. The deal behind it: opt in, and your builds help train open models. It asks every time you switch in. The research preview runs Sept 14 to Oct 14, 2026. Forge is free on Pro plans until Oct 14, and there's a $9/month early-access plan, Bolt Lite, with a waitlist. It's experimental, so duplicate your project before bringing anything serious in. Watch the 3 builds, then try Forge with the link below.
