| FIKA-Bench Research and Evaluation License |
| Version 1.0, May 16, 2026 |
|
|
| This license applies to the FIKA-Bench benchmark package and annotations |
| distributed through gated access, including but not limited to questions, |
| answers, fine-grained labels, evidence links, taxonomy metadata, manifests, and |
| benchmark organization. Images and other third-party materials remain subject to |
| their original licenses, terms, and rights. This license does not supersede any |
| third-party license that applies to an individual image or source item. |
|
|
| 1. Permitted Use |
|
|
| You may use FIKA-Bench for non-commercial research, academic evaluation, |
| benchmark reproduction, and analysis of fine-grained visual knowledge |
| acquisition in machine learning systems. |
|
|
| You may report aggregate evaluation results, error analyses, and model |
| predictions, provided that the ground-truth answers, fine-grained labels, |
| evidence links, and full annotation files are not publicly redistributed. |
|
|
| 2. Access and Redistribution |
|
|
| FIKA-Bench is distributed through gated access. You may not redistribute, |
| mirror, re-upload, sublicense, sell, or publicly release the full benchmark |
| package, the annotation files, ground-truth answers, fine-grained labels, |
| evidence links, or substantially equivalent derived files. |
|
|
| You may not publish a copy of the dataset in a way that bypasses the gated |
| access process. Redistribution rights for individual third-party images, if any, |
| are governed by their original source licenses rather than by this license. |
|
|
| 3. Benchmark Integrity |
|
|
| You may not use the ground-truth answers, fine-grained labels, evidence links, |
| or annotation files as training data, fine-tuning data, retrieval databases, |
| prompt context, memory stores, or tool-accessible resources for a model that is |
| being evaluated on FIKA-Bench. |
| |
| You may not design an evaluation setup that gives a tested model direct or |
| indirect access to FIKA-Bench ground-truth annotations, evidence, or leakage |
| signals beyond the intended test input. |
|
|
| 4. Privacy and Responsible Use |
|
|
| The released images have been reviewed and redacted where needed, but you must |
| not attempt to identify, deanonymize, recover, or associate private individuals, |
| license plates, addresses, or other sensitive personal information that may |
| appear in or be inferred from the images. |
|
|
| You must not use FIKA-Bench for surveillance, biometric identification, |
| profiling, or other privacy-invasive applications. |

| 5. Attribution |

| If you use FIKA-Bench in a publication, report, or public result, please cite: |

|
| 6. No Warranty |
|
|
| FIKA-Bench is provided "as is", without warranty of any kind, express or |
| implied. The authors and distributors are not liable for any claim, damages, or |
| other liability arising from use of the benchmark. |
| |
| 7. Additional Permission |

| For commercial use, redistribution, hosting, or uses outside the scope of this |
| license, please contact the FIKA-Bench authors for permission. |
