Data stays local
Every millisecond of latency is friction between you and your answer. We eliminated the biggest bottleneck: the network.
Typical first-token latency based on internal benchmarks. Cloud provider estimates reflect publicly available API performance data and may vary. Stone AI™ local inference benchmarked on NVIDIA RTX 5090. Actual performance depends on hardware, network conditions, and query complexity.
Local GPU inference delivers answers before cloud AI even receives your request. Every response shows its latency — because we have nothing to hide.
Running the latest open-weight 70B models — and always upgrading to the best available. Smart mode adds GPT-4o when you need the absolute cutting edge.
Conversations never leave your network. No third-party API calls on the free tier. HIPAA-friendly. GDPR-ready. Compliance by design.
No API middleman means our free tier costs us almost nothing. No credit card, no trial, no catch. Upgrade when you need more speed or smarter models.
Free tier, no credit card. Start chatting immediately.
Your messages go to a local GPU — not OpenAI, not the cloud. Lightning-fast responses.
Need GPT-4o? Smart and Pro tiers add cloud fallback for complex tasks while keeping local as default.
Healthcare, legal, finance — if your data can't touch the cloud, Stone AI™ is the only answer. Local inference means true data sovereignty. No BAA needed when data never leaves your network.
Every tier unlocks faster responses and smarter capabilities. Start free, scale when you're ready. Cancel anytime.
