AI inference.
Faster.
PolarGrid runs GPU nodes at the edge — closer to your users than any cloud. Top open models. Sub-300ms voice pipelines. Faster than any hyperscaler.
Why PolarGrid
Built for latency-critical AI.
Every design decision is optimized for one thing: making your AI models as fast as possible.
Distributed nodes. Lower Latency.
Every request intelligently routes to the lowest TTFT node for that particular user. PolarGrid eliminates those 100ms+ additional network hops by running inference at the edge, not a distant cloud region.
<30ms P95
Full pipeline. One hop.
STT → LLM → TTS runs co-located on a single node — no cross-service calls, no cross-region round trips. The entire voice pipeline completes in under 300ms.
sub-300ms TTFA
No cold starts. Ever.
Models are loaded and warm on PolarGrid nodes 24/7. No spinning up containers, no queue waiting, no first-request penalty. Request in, inference out.
0ms cold start
OpenAI-compatible API.
Drop-in replacement. Change one line of code — your base URL — and you're on PolarGrid. Every SDK, framework, and tool you already use continues to work.

Sub-300ms TTFA
Your users don't experience tokens per second.
They experience the wait. The pause before the voice agent speaks. The gap that tells them they're talking to a machine.
PolarGrid obsesses over one number: TTFA — Time to First Audio. From end of user speech to first audio byte delivered. Sub-300ms. Every time.

Integration
One line to switch.
PolarGrid is a drop-in replacement for the OpenAI API. Change your base URL and you're done. Every SDK, framework, and integration you already use continues to work.
Auto-routing built in
The SDK pings all edge nodes and picks the fastest one for you. No config required.
Same auth model
API keys work the same way. Generate one in the console at app.polargrid.ai.
Python & TypeScript SDKs
Native SDKs available. Or use any OpenAI-compatible library directly.
// Before: any OpenAI-compatible provider const client = new OpenAI({ baseURL: "https://api.openai.com/v1", apiKey: process.env.OPENAI_API_KEY, }); // After: PolarGrid — edge-routed, faster const client = new OpenAI({ baseURL: "https://autorouter.edge.polargrid.ai/v1", apiKey: process.env.POLARGRID_API_KEY, }); // Same API. Same models interface. // Sub-300ms TTFA. Up to 70% lower latency.
Use cases
Any product where speed matters.
Voice AI
The pause kills the conversation.
When a voice agent takes 1–2 seconds to respond, users feel it. Sub-300ms TTFA is the threshold where AI voice feels real. PolarGrid is built for that bar.
sub-300ms TTFA
LLM Applications
Faster tokens. Lower bills.
Real-time chat, coding assistants, document processing — anything that streams tokens benefits from edge inference. Faster responses, day one.
From $0.05/1M tokens
High-Volume Pipelines
Scale without the lag tax.
High-volume inference pipelines eat performance at scale. PolarGrid's edge nodes and intelligent routing mean your latency stays low as you scale up.
Up to 15% off at scale
Video & Computer Vision AI
Real-time video inference at the edge. Object detection, scene understanding, and vision models — sub-100ms, at scale.
Custom model hosting
Run your models at the edge.
Fine-tuned model? Proprietary weights? Custom voice? Bring it to PolarGrid. Your models, our edge infrastructure — faster than running it yourself.
