We support flexible compute sizing in Bult.ai so apps only use what they actually need.

XS to XL sizes cover everything from prototypes to databases, with per-minute billing and the ability to resize anytime from the Canvas UI.
Compute options:
XS: 0.1 vCPU, 256 MB RAM, $2.7 per month. Ideal for prototypes
S: 0.25 vCPU, 512 MB RAM, $5.4 per month. Suitable for small apps
M: 0.5 vCPU, 1 GB RAM, $12 per month. Designed for web applications
L: 1 vCPU, 2 GB RAM, $24 per month. A good fit for APIs
XL: 2 vCPU, 4 GB RAM, $48 per month. Optimized for databases

Custom sizes are also available for advanced workloads available on request.
Happy to answer questions about sizing or use cases.
