Runs On

What it takes to serve Kronos-base (102M parameters): the memory its weights need at each precision, and the cheapest way to rent enough data-center GPUs to hold them.

Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the SAVRN Index, read Sep 18, 2026.

SAVRN's Notes on Kronos-base

Two tenths of a gigabyte at 16-bit. That is the entire footprint of Kronos-base, ShiYu's 102M parameter decoder-only forecaster for candlestick sequences, pretrained on OHLCV data from more than 45 global exchanges. The cheapest Index listing that holds it is one MI300X with 192 GB at $1.85 an hour, so the card is the floor of the price list, not a demand of the model. Share the accelerator with other jobs.

MIT terms allow commercial use, modification and redistribution as long as the copyright and permission notices travel with the weights. The file lists no context length, so read the paper it cites, arXiv:2508.02739, for the window it accepts, and read how its tokenizer quantizes OHLCV into discrete tokens, since your data passes through that step first. Access is open, the four safetensors files total about 409 MB, and the last update landed September 9, 2025.

Kronos: A Foundation Model for the Language of Financial Markets

Kronos is the first open-source foundation model for financial candlesticks (K-lines), trained on data from over 45 global exchanges. It is designed to handle the unique, high-noise characteristics of financial data.

Introduction

Kronos is a family of decoder-only foundation models, pre-trained specifically for the "language" of financial markets—K-line sequences. It leverages a novel two-stage framework: 1. A specialized tokenizer first quantizes continuous, multi-dimensional K-line data (OHLCV) into hierarchical discrete tokens. 2. A large, autoregressive Transformer is then pre-trained on these tokens, enabling it to serve as a unified model for diverse quantitative tasks.

Questions About Kronos-base

How much GPU memory does Kronos-base need?

About 0.2 GB at 16-bit and 0.1 GB at 4-bit: the weights (102M parameters) plus a working margin. A long context needs more.

What is the cheapest GPU to run Kronos-base on?

At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.

Can I use Kronos-base commercially?

Yes. Kronos-base is released under MIT License. The MIT License is a short permissive license. It permits commercial use, modification and redistribution, provided the copyright notice and permission notice are included.

MOMENT is a family of foundation models for general-purpose time-series analysis. The models in this family (1) serve as a building block for diverse time-series analysis tasks (e.g., forecasting, classification, anomaly detection, and imputation, etc.), (2) are effective out-of-the-box, i.e., with no (or few) task-specific exemplars (enabling e.g., zero-shot forecasting, few-shot classification, etc.), and (3) are tunable using in-distribution and task-specific data to improve performance.
