What it takes to serve Kronos-small (25M 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-small

Candlestick sequences are the entire job here. Kronos-small takes OHLCV data its own tokenizer has quantized into discrete tokens and forecasts what comes next, trained on more than 45 global exchanges. At 25M parameters the four weight files total under 99 MB, and the 16-bit run needs 0.1 GB of memory. The cheapest Index setup, one MI300X with 192 GB at $1.85 per hour, would barely register it. We would put it on a card already serving other work rather than give it one of its own.

MIT is about as short as a license gets: commercial use, modification and redistribution, as long as the notices ride along. Two checks before committing. The facts list no context length, so establish the K-line window from the paper, arXiv:2508.02739. And the weights were updated September 9, 2025, two months after the June 30 release, so confirm which revision you are pulling.

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-small

How much GPU memory does Kronos-small need?

About 0.1 GB at 16-bit and 0 GB at 4-bit: the weights (25M parameters) plus a working margin. A long context needs more.

What is the cheapest GPU to run Kronos-small 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-small commercially?

Yes. Kronos-small 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.

Datadog

Toto (Time Series Optimized Transformer for Observability) is a family of time series foundation models for multivariate forecasting developed by Datadog. Toto 2.0 is the current generation, featuring u-μP-scaled transformers ranging from 4m to 2.5B parameters, all trained from a single recipe. Forecast quality improves reliably with parameter count across the family. The family sets a new state of the art on three forecasting benchmarks: BOOM, our observability benchmark; GIFT-Eval, the standard general-purpose benchmark; and the recent contamination-resistant TIME benchmark. Inference code is available on GitHub. For more examples, see the Quick Start notebook and GluonTS integration…

Check out the tutorial notebook to learn how to deploy Chronos endpoints for production use in a few lines of code. Chronos-Bolt is a family of pretrained time series forecasting models which can be used for zero-shot forecasting. It is based on the T5 encoder-decoder architecture and has been trained on nearly 100 billion time series observations. It chunks the historical time series context into patches of multiple observations, which are then input into the encoder. The decoder then uses these representations to directly generate quantile forecasts across multiple future steps—a method known as…
