Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Fireworks AI

  • Reserved and enterprise-tier pricing is not published and requires sales contact.
  • Model catalog is curated to ~30 models, smaller than DeepInfra's 100+ model library.
  • On-demand GPU rates are scheduled to increase from September 1, adding cost unpredictability for locked-in workloads.

SolidStart

  • Smaller ecosystem compared to Next.js or Remix due to relative newness
  • SolidJS less familiar to developers with React experience
  • Community documentation not as extensive as larger frameworks
  • Limited third-party UI component libraries compared to React ecosystem

SolidStart: What is SolidJS and how does it differ from React?

SolidJS uses fine-grained reactivity and automatic dependency tracking instead of React's virtual DOM, resulting in smaller bundles and better performance.

Source
Fireworks AI: Is there a free tier or trial credit?

New accounts receive $1 in free credit to try serverless inference before adding a payment method.

Source
SolidStart: How many deployment platforms does SolidStart support?

SolidStart supports over 20 deployment platforms including Cloudflare, Netlify, Vercel, Deno, AWS, and Azure through Vite plugins.

Source
Fireworks AI: How much do on-demand GPU deployments cost?

Dedicated on-demand instances range from $7-8/hour for H100/H200 GPUs up to $18-20/hour for GB300, billed per GPU second with no start-up surcharge.

Source
SolidStart: Can I use TanStack Router with SolidStart?

Yes, SolidStart supports using either the official Solid Router or TanStack Router depending on project requirements.

Source
Fireworks AI: How is fine-tuning priced?

Managed training is billed per 1 million training tokens for supervised or preference tuning, while reinforcement tuning is billed per GPU hour.

Source
Fireworks AI: Does region selection affect pricing?

Yes, region-restricted on-demand deployments carry a 1.5x premium over standard regional pricing.
