AI infrastructure should be invisible
The best infrastructure gets out of your way. You should not think about API versions, token counting differences, or provider-specific error codes. You should focus on building your product.
One API for Open-Source and Closed-Source AI Models
NusaBase is an AI API aggregation platform that gives developers unified access to open-source models and premium closed-source model APIs for text, image, video, audio, and multimodal generation.
We started NusaBase because developers should not have to choose between model quality and integration complexity.
Every AI provider has its own SDK, billing system, rate limits, and API conventions. Building a production app meant maintaining dozens of integrations, writing custom fallback logic, and constantly monitoring for breaking changes.
We built the infrastructure layer we wished existed: one API that connects you to every major AI model, with intelligent routing, unified observability, and transparent pricing.
What we believe
Choice is a feature, not a problem
New models launch every week. Being locked into a single provider means missing breakthroughs. We believe developers should experiment freely, switch models instantly, and run A/B tests without rewriting code.
Pricing should be transparent
No hidden markup. No surprise bills. We pass through provider pricing exactly as-is and show you real-time cost breakdowns. You pay for what you use, nothing more.
Production reliability is non-negotiable
When your users depend on AI features, downtime is not acceptable. We built automatic failover, circuit breakers, and intelligent retries so your app stays online even when providers do not.
Who we built this for
NusaBase is built for developers and teams who need reliable AI infrastructure without the operational overhead.
Startups use us to ship AI features faster. Switching from GPT-4 to Claude takes one line of code, not a week of refactoring.
Product teams use us to A/B test models without touching production infrastructure. Compare response quality, latency, and cost in real-time.
Enterprise AI teams use us for production reliability. When a provider goes down, requests automatically route to alternatives. Your users never notice.
Solo developers use us because we handle the complexity they do not have time for: auth, rate limiting, retries, observability, and cost optimization.
How it works
Behind the simple API is production-grade infrastructure designed for reliability and performance at scale.
1
Unified API layer
One consistent interface for every model. We normalize request formats, handle auth, and manage provider-specific quirks so you do not have to.
2
Intelligent routing
Requests route to the fastest available endpoint. If a provider is slow or down, we automatically failover. You get sub-200ms overhead on average.
3
Real-time observability
Track every request with detailed logs, latency metrics, and cost breakdowns. Debug production issues in minutes, not hours.
4
Cost optimization
We show you exactly what each request costs across providers. Switch to cheaper models for simpler tasks. Set budget limits to prevent overages.
