Ising Calibration 1.5 also uses examples from related experiments when available and is 11.4% smaller at BF16 precision. This eases the deployment of agentic calibration workflows directly in local lab environments.\n\nFor the first time, the model is also available in an [NVFP4](https://developer.nvidia.com/blog/introducing-nvfp4-for-efficient-and-accurate-low-precision-inference/)-quantized version, enabling deployment on a single GPU or an NVIDIA DGX Spark—comparable with leading closed models such as Fable 5 and GPT 5.6 Sol.\n\n## How is the Ising Calibration 1.5 model trained?\n\nThe Ising Calibration 1.5 model is trained on data generated from partner contributions across multiple qubit modalities, including superconducting qubits, quantum dots, ions, neutral atoms, electrons on Helium, and others specializing in calibration and control.\n\n## How is Ising Calibration 1.5 performance evaluated?\n\nPerformance of Ising Calibration 1.5 is evaluated using the [QCalEval benchmark](https://github.com/nvidia/QCalEval), which measures a model’s ability to interpret experimental results, classify outcomes, evaluate significance, assess fit quality and key features, and recommend next steps. For additional details on the benchmark, model architecture, and evaluation results, see [QCalEval: Benchmarking Vision-Language Models for Quantum Calibration Plot Understanding](https://arxiv.org/abs/2604.25884).\n\nThe evaluation covers both zero-shot and in-context learning (ICL). Zero-shot reasoning analyzes results independently, while ICL evaluates results in the context of related samples. Both are important for building agents that can automate QPU bring-up and retune operations.\n\nOn the QCalEval benchmark, Ising Calibration 1.5 shows strong performance when analyzing diagnostic results without prior examples. It is now also 86.68% better than its predecessor when using examples from related experiments. It outperforms comparable open models and remains competitive with leading closed models.\n\nIsing Calibration 1.5 advances AI and quantum computing calibration by outperforming all open models out of the box and on the QCalEval benchmark. It is competitive with state-of-the-art closed or 1T+ parameter models.\n\nThe 31-billion-parameter VLM is suited for data center GPUs such as NVIDIA Grace Blackwell and NVIDIA Vera Rubin. It also ships with a quantized version to NVFP4 where users can run this model on a consumer gaming card or [NVIDIA DGX Spark](https://www.nvidia.com/en-us/products/workstations/dgx-spark/) with only a small cost in accuracy.\n\nThe tokens per second (TPS) performance on DGX Spark has also been optimized, enabling good throughput locally for a fraction of the cost.\n\nTo learn more about deploying Ising Calibration 1.5 with an agent, check out the [NVIDIA/Quantum-Calibration-Agent-Blueprint](https://github.com/NVIDIA/Quantum-Calibration-Agent-Blueprint/) GitHub repo.\n\n## Get started with NVIDIA Ising open resources\n\nThe [NVIDIA Ising](https://www.nvidia.com/en-us/solutions/quantum-computing/ising/) model family is fully open.
