Version upgrades of evaluation benchmarks are often accompanied by adjustments to scoring conventions such as normalization methods, task weights or aggregation algorithms, so the same model's scores under the old and new versions cannot be directly subtracted.

UnverifiedParser version upgrades often quietly change scores: model weight updates, post-processing rule adjustments, and even minor version changes of dependency libraries (such as PDF parsing libraries and image processing libraries) can all affect the output.77% similarUnverifiedModel version upgrades are not always linear improvements; new versions sometimes exhibit capability regressions on certain specific tasks.75% similarUnverifiedVendors may perform inference optimizations (such as quantization, speculative decoding, and KV cache strategy adjustments) or infrastructure changes within the same named version, and these changes will not be reflected in the version number.72% similarUnverifiedIn a dependency chain, patch versions can still introduce behavioral changes through upgraded transitive dependencies, so it is recommended to run the test suite even for patch updates.72% similarUnverifiedThe version under test includes not only the software version number but also the model, parameters, prompts, and context in use; any change to any of these means the version under test has changed.72% similar
