Start Inferencing

Run unlimited inference on your dedicated GB10 hardware. Scale up anytime.

# Just change the base URL — everything else stays the same
from openai import OpenAI

client = OpenAI(
    base_url="https://api.sparkserve.io/v1",
    api_key="your-api-key"
)

response = client.chat.completions.create(

Inference + Agents, One Box

The only managed service that bundles LLM inference and an AI agent platform — no API keys to bring

🔗

OpenAI-Compatible API

vLLM runs on your dedicated GB10. NemoClaw's gateway exposes an OpenAI-compatible endpoint — swap your base_url and go. No external API keys needed.

🤖

NemoClaw WebUI

Manage always-on AI agents from a browser. OpenShell sandboxing keeps agents secure. Build, monitor, and evolve your agents — all through one dashboard.

Performance

Real-world inference benchmarks on NVIDIA GB10 Grace Blackwell

Model Parameters Throughput Quantization
Qwen 3.5 27B 27B ~56 tok/s NVFP4
Llama 4 Scout 17B-A16E ~50 tok/s NVFP4
DeepSeek-R1 Distill 70B 70B ~30 tok/s NVFP4
Nemotron Nano 30B 30B-A3B MoE ~56 tok/s NVFP4

Measured on a single GB10 node with vLLM + NVFP4 quantization. Actual throughput varies by prompt length and concurrency.

In Production

How we use SparkServe ourselves

N
Nakamu-Tech Inc.
AI Scrum Master Agent

We run an always-on Scrum Master agent powered by NemoClaw on our own SparkServe Pro instance. It manages sprint planning, tracks Jira tickets, posts daily standups to Slack, and flags blockers automatically. The agent runs 24/7 on a dedicated GB10 with Qwen 3.5 27B — no per-token costs, no cold starts, consistent sub-second latency.

FAQ

Common questions about SparkServe

Why is this so affordable?
We own all hardware outright — no cloud provider markup, no data center lease. The NVIDIA GB10's ultra-efficient 200W power draw keeps operating costs under $20/month per unit. No VC-funded burn rate, no enterprise sales team. We pass the savings directly to you.
How does this compare to other GPU clouds?
A dedicated A100 80GB on RunPod costs ~$2/hr ($1,440/month) — and you still set up vLLM, manage Docker, and handle ops. Together AI and Groq charge per-token with no cost ceiling. SparkServe Pro gives you 128GB unified memory, a fully managed API, and NemoClaw — all for a flat $299/mo. No setup, no Docker, no per-token surprises.
What's the catch? Is this a shared instance?
No catch. The Starter plan shares hardware across a small number of users with rate limits. The Pro plan gives you a fully dedicated GB10 Superchip — no other users, no noisy neighbors, consistent performance 24/7.
How does GB10 performance compare to A100 / H100?
The GB10 delivers up to 1 PFLOP at FP4 with 128GB unified memory connected via NVLink-C2C. While raw throughput is lower than an H100, the unified memory architecture means larger models fit without quantization trade-offs. For most inference workloads under 200B parameters, it's a sweet spot of cost and capability.
Can I switch models?
Yes. Contact us and we'll swap the model on your instance — typically within a few hours. During Early Access, model changes are included at no extra cost.
What about uptime and reliability?
During Early Access, we target 99% uptime with transparent maintenance windows. Enterprise plans include a 99.9% SLA with guaranteed response times. All maintenance is scheduled and communicated in advance.
What's the difference between Starter and Pro?
Starter shares a GB10 across a small number of users with rate limits (10 req/min, 100K/month, models up to 30B). Pro gives you a fully dedicated GB10 — unlimited requests, models up to 100B, custom model deployment, and NemoClaw/OpenClaw pre-installed for running always-on AI agents.
What is NemoClaw / OpenClaw?
OpenClaw is an open-source framework for running always-on AI agents locally. NemoClaw is NVIDIA's enterprise version with built-in security sandboxing and guardrails. Pro plans include NemoClaw pre-installed with a WebUI for agent management and an OpenAI-compatible API running on the same stack — inference and agents on one dedicated machine.
