QVAC AI is Tether’s new platform that lets you run large‑language‑model inference entirely on a local GPU, removing any reliance on cloud compute. By compiling models into optimized GPU graphs, it delivers near‑zero latency for chatbots, recommendation engines, and other real‑time AI tasks. The result is faster responses, lower costs, and data that never leaves your device.
Compiler‑First Model Conversion
At the core of QVAC is a compiler that transforms standard PyTorch models into inference‑ready GPU graphs. This process automatically handles key optimizations such as KV‑cache management, sharding, and kernel selection, so you don’t have to write custom CUDA code or manually quantize your model. The compiled engine runs directly on consumer‑grade GPUs with minimal overhead.
Edge‑Optimized Hardware Compatibility
QVAC is designed to be GPU‑agnostic, but its performance shines on modern discrete GPUs that offer ample memory and bandwidth. Benchmarks show that the platform matches the capabilities of the latest graphics cards, proving that today’s hardware can host full‑scale LLM inference without bottlenecks.
Speed Gains on the Edge
Running inference locally cuts the “time to first token” dramatically because you eliminate network round‑trip delays. In internal tests, QVAC reduced response times by more than half compared to cloud‑based alternatives, delivering a noticeably snappier user experience.
Real‑World Performance Validation
Developers who have integrated QVAC report 2‑3× faster inference than naïve PyTorch runs on the same GPU. These results align with broader community observations that optimized GPU graphs consistently outperform unoptimized models.
Adaptive Kernel Learning During Inference
QVAC includes a lightweight runtime that fine‑tunes kernel choices on the fly. As the model processes real workloads, the system learns which kernels deliver the best performance and automatically applies those optimizations, keeping speed steady even as usage patterns evolve.
What This Means for You as a Developer
With QVAC, your workflow becomes straightforward: pull a model from a repository, feed it to the compiler, and deploy the resulting engine to any supported GPU. No extra CUDA kernels, no manual quantization scripts, and no cloud API keys. Because everything runs on‑device, you retain full control over data privacy—ideal for healthcare, finance, and other regulated sectors.
Practitioner Perspective
“Latency was always the Achilles’ heel of our voice assistants,” says a senior ML engineer who recently piloted QVAC. “The compiler saved us weeks of hand‑tuning, and on‑device inference cut round‑trip latency from 350 ms to under 120 ms. The adaptive kernel learning kept performance stable as we added new intents.”
Implications and Next Steps
If QVAC lives up to its promise, you could soon build AI products that run completely offline—think smart home hubs that answer questions without ever contacting a server, or enterprise analytics tools that process confidential data on‑premises. While large‑scale training still requires powerful clusters, inference is clearly shifting toward the edge.
Success will depend on continued support from GPU vendors and the broader developer community. Keep an eye on compiler updates and benchmark results to ensure your deployments stay ahead of competing edge solutions.
