How is Vast.ai pricing handled on Railwail?
Railwail uses transparent per-call or per-token credit pricing for all Vast.ai models. You pay only for what you use — no monthly minimums, no upfront commitments. Pricing for every individual Vast.ai model is shown on its detail page.
Are there rate limits when using Vast.ai via Railwail?
Default rate limits depend on your account tier and the underlying Vast.ai capacity. Free-tier accounts get sensible defaults for development; paid accounts can request higher limits. Contact support if you need dedicated throughput or burst capacity.
Which regions does Vast.ai support through Railwail?
Vast.ai models are served from Railwail's globally distributed edge infrastructure. EU, US, and Asia-Pacific traffic is automatically routed to the nearest available provider region. GDPR-compliant EU-only routing is available on request.
Is there a sandbox or free tier to test Vast.ai models?
Yes — every new Railwail account receives free credits that work across all providers, including Vast.ai. No credit card is required to start. You can try every model in the catalog before committing to a paid plan.
