The Platform

One platform.
Two model classes.

Quantum Junction is purpose-built to host both task-specific SLMs and frontier LLMs — with the same enterprise-grade reliability, security, and observability.

Core Capabilities

Everything you need to run production AI

From one-click deployment to fine-tuning to observability — all in one platform.

One-click deployment

Deploy any HuggingFace-compatible model in under 60 seconds. SLMs, LoRA adapters, quantized GGUF, or full frontier checkpoints — same API surface, same endpoint format.

🎯

Smart routing

Route each request to the right model automatically. Query complexity scoring sends simple tasks to your SLM and complex reasoning to your LLM — cutting average costs by 70%.

🧠

Fine-tune studio

Upload your dataset, choose a base model, and launch a supervised fine-tuning run. DPO, RLHF, and LoRA supported. Your data never leaves your VPC.

📊

Benchmark suite

Run your SLM and LLM head-to-head on your actual production tasks before going live. Export structured accuracy, latency, and cost comparison reports.

🔒

Enterprise security

Private VPC deployment, end-to-end encryption, SOC 2 Type II certified, HIPAA BAA available. Complete audit logs for every inference call.

📈

Observability

Token-level latency, cost-per-request, hallucination detection scores, and model drift alerts — all in one dashboard with Prometheus and Grafana export.

Infrastructure

Built on purpose-built GPU infrastructure

Quantum Junction runs on A10G and H100 GPU fleets purpose-built for inference, not repurposed cloud VMs.

🖥

NVIDIA A10G Fleet

24GB VRAM per GPU. Optimal for SLMs up to 13B parameters. p50 latency of 12ms for 3B models at 100 concurrent requests.

🚀

NVIDIA H100 Fleet

80GB VRAM per GPU. For frontier LLMs up to 70B parameters. Multi-GPU tensor parallelism for 405B+ models with NVLink interconnects.

Autoscaling from 0

Scale from zero to 10,000 RPS in seconds. Predictive pre-warming based on your historical traffic patterns means no cold-start latency spikes.
