Supported Operating System(s): Linux

The integration of foundation and fine-tuned models into AI systems requires additional testing using use-case-specific data to ensure safe and effective deployment. Following the V-model methodology, iterative testing and validation at both unit and system levels are essential to mitigate risks, meet technical and functional requirements, and ensure compliance with safety and ethical standards before deployment.

This AI model can be embedded as an Application Programming Interface (API) call into the software environment described above.

Training, Testing, and Evaluation Datasets:

Training Dataset:

Data Modality:

• Image
• Text

Image Training Data Size: Less than a Million Images
Text Training Data Size: Less than a Billion Tokens
Data Collection Method by dataset: Synthetic
Labeling Method by dataset: Synthetic
Properties (Quantity, Dataset Descriptions, Sensor(s)): The training corpus contains 72.5K total supervised entries: 23.8K ICL-formatted entries for multi-image demonstrations and 48.7K zero-shot entries augmented using Qwen3.5-397B-A17B. The data comes from NVIDIA quantum-calibration/QCal-style synthetic data generation and focuses on calibration plot interpretation. The dataset was assembled for the 2026 Ising Calibration 1.5 release cycle.

Testing Dataset:

Data Collection Method by dataset: Synthetic
Labeling Method by dataset: Synthetic
Properties (Quantity, Dataset Descriptions, Sensor(s)): QCalEval was used as the primary external release validation benchmark for Ising Calibration 1.5. It is a quantum-calibration evaluation suite with multimodal plot-plus-text tasks covering zero-shot and ICL/few-shot settings across calibration interpretation, parameter extraction, diagnostic reasoning, and calibration-status classification. The release candidate was evaluated on 243 zero-shot examples with 1,458 response slots and 236 ICL examples with 708 response slots; raw outputs were checked for completeness and server errors, then judged with both GPT and Gemini judges to produce aggregate scores. The benchmark uses curated quantum-calibration plot tasks rather than raw sensor telemetry, and should be interpreted as domain validation rather than a broad general-purpose capability benchmark.

Evaluation Dataset:

Benchmark Score: QCalEval benchmark scores. Scores are the simple average of GPT-5.4 and Gemini-3.1-Pro judges.

Zero-shot scores:

MM-ICL scores:

Data Collection Method by dataset: Synthetic
Labeling Method by dataset: Synthetic
Properties (Quantity, Dataset Descriptions, Sensor(s)): The evaluation dataset is QCalEval, a synthetic vision-language benchmark for quantum calibration plots containing 243 entries across 87 scenario types from 22 experiment families, covering superconducting qubits and neutral atoms. It assesses six question types: technical description, experimental conclusion, experimental significance, fit quality assessment, parameter extraction, and experiment success classification. Ground-truth labels are derived from simulation parameters, providing curated quantum calibration experiments.

Inference:

Acceleration Engine: vLLM
Test Hardware: NVIDIA Hopper (H100x2, TP2)
