 > TL;DR: Foundation models for time series outperform alternatives and are ready to be tested in production. TimeGPT-1 is (so far) the most accurate and fastest model but TimesFM from Google comes very close. Some models are still outperformed by classical alternatives.
 
+Note: The Amazon team responded to the original benchmark with this [PR](https://github.com/Nixtla/nixtla/pull/382) that shows, according to them, that by changing some parameters, Chronos is significantly faster and more accurate. We are currently reviewing the PR.

 However, the field [is still divided](https://news.ycombinator.com/item?id=39235983) on how all the different foundation models compare against each other. In the spirit of collaboration, we are starting a new project, `xiuhmolpilli`, in honor of how ancient civilizations celebrated the end of cycles, to build a benchmark to compare all the different foundation models for time series data in a large scale dataset and against classical, ML and Deep Learning Models.

 # Empirical Evaluation
 
 This study considers **over 30,000 unique time series** from the Monash Repository, M-Competitions, Wikipedia page views, among others, spanning various time series frequencies: Monthly, Weekly, Daily, and Hourly. Our evaluation compares five foundation models for time series data in terms of accuracy and inference times. We have also included comparisons to a large battery of statistical, machine learning, and deep-learning models, to provide a benchmark against traditional forecasting methods.
