Best LLM for Bolt.new
Bolt.new generates entire full-stack apps from a prompt and iterates in the browser, so it leans hard on a model's ability to produce coherent, runnable multi-file code — a place where the strongest coding models pull ahead.
Models Bolt.new supports
Bolt.new is a browser-based AI app builder that scaffolds and runs full-stack projects; it leans on frontier coding models (Claude and GPT families) to generate and iterate on whole codebases.

Intelligence scores are community Arena ratings from LMArena / arena.ai, used under CC BY 4.0. Snapshot last refreshed 2 November 2026. Scores are a relative signal, not an absolute measure of capability. A Measured score was voted on directly; an Estimated score is inherited from an identical base model (a regional/creator-prefixed hosting duplicate). See our methodology.
Why picking isn’t obvious
Whole-app generation is one of the more demanding coding tasks: the model has to keep many files consistent, so a top coding-Arena model reduces broken builds and re-prompts. But token usage is heavy, so value still matters. We rank the coding-capable models by Arena score and cost to show where quality justifies the spend.
FAQ
What is the best value LLM for bolt?
MiMo-V2.6-Flash is the cheapest model that still clears our quality bar for this task, at about $35.00/month for 100,000 calls (1,500 in / 500 out). It scores 1637 on the Coding Arena.
Is the most expensive model worth it for this?
Claude Opus 5.5 tops the Coding Arena but costs about $1,600.00/month here — roughly $1,565.00/month more than MiMo-V2.6-Flash for 173 extra Arena points. For most workloads that gap is not worth the premium.
Why do stronger models help more with Bolt.new?
Generating a whole app in one shot stresses multi-file consistency and instruction following, so a higher coding-Arena model produces runnable output more often — fewer wasted regenerations, which also saves tokens on a heavy workload.
Is a cheaper model ever the right call for Bolt-style building?
For small tweaks and simple scaffolds, yes — a mid-tier coding model handles them fine and costs less. Reserve the flagship for large, from-scratch generations where consistency matters most.
