[VLDB' 25] ChatTS 14B 0801 Model [VLDB' 25] ChatTS: Aligning Time Series with LLMs via Synthetic Data for Enhanced Understanding and Reasoning ChatTS focuses on Understanding and Reasoning about time series, much like what vision/video/audio MLLMs do. This repo provides code, datasets and model for ChatTS : ChatTS: Aligning Time Series with LLMs via Synthetic Data for Enhanced Understanding and Reasoning. Web Demo The Web Demo of ChatTS 14B 0801 is available at HuggingFace Spaces: Key Features ChatTS is a Multimodal LLM built natively for time series as a core modality： ✅ Native support for multivariate time series ✅ Flexible input : Supports multivariate time series with different lengths and flexible dimensionality ✅ Conversational understanding + reasoning : Enables interactive dialogue over time series to explore insights about time series ✅ Preserves raw numerical values : Can answer statistical questions , such as "How large is the spike at timestamp t?" ✅ Easy integration with existing LLM pipelines , including support for vLLM . Example Application Here is an example of a ChatTS application, which allows users to interact with a LLM to understand and reason about time serie…
