Comparison
QuickSilver Pro vs NVIDIA NIM
NIM is NVIDIA's containerized inference: ship a Docker image, deploy on your own H100s/H200s, or call the hosted endpoint at build.nvidia.com. It's the right fit when you have GPU capacity to fill or strict data-locality requirements that rule out shared inference. For everyone else, QuickSilver Pro runs the latest DeepSeek and Qwen weights as a managed OpenAI-compatible service — no Kubernetes, no GPU operator, no Triton configs.

FAQ
When you already pay for GPUs that would otherwise sit idle, when data-locality forces inference to specific regions, or when you need a custom-finetuned model. The break-even math: an H100 at ~$2/hr serves a few hundred tokens/sec, so the cost-per-token only beats QSP when your H100 is sustainably above ~60% utilization. Below that, you're paying for idle GPUs.
Pricing varies by model and tier. On the DeepSeek V4 wave, QSP holds the line at $0.70 / $2.10 (V4 Pro) and $0.06 / $0.18 (V4 Flash) with a transparent OpenAI-compatible surface. Sign-up friction is lower on QSP (paste a key) than on NGC (NVIDIA developer account + quota).
Yes — NIM exposes an OpenAI-compatible /v1 endpoint, so swapping base_url is enough. Same SDK, same shape, same streaming / tool-calling behavior. Replace the NIM-qualified model name with QSP's stable V4 ID, such as deepseek-v4-pro.
Not disclosed publicly. The contract we make to callers is OpenAI-compatible chat + tool calling + JSON schema on the models that support it + usage accounting, with the listed per-token price and uptime — how that's delivered is an implementation detail that's evolved over time and will continue to. Status and per-model latency are public at /status.
