What it takes to serve timesfm-2.5-200m-pytorch (231M 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 timesfm-2.5-200m-pytorch

Forecasting work, not text. Google's third open TimesFM checkpoint takes a run of past values and predicts the ones ahead, served through the timesfm package. In 16-bit form the weights come to 0.5 GB and need 0.6 GB of memory. The cheapest setup in our table, one 192 GB MI300X at $1.85 per hour on demand, is far more card than this will fill; pack it in beside other jobs on hardware you already run.

Apache 2.0 allows commercial use, modification and redistribution, provided the license, copyright notices and NOTICE file travel with it and significant changes are stated. Two checks. Google labels this checkpoint as not an officially supported product and points support at TimesFM in BigQuery, so an in-house deployment carries its own support burden. And the pretraining data on record stops at November 2023 for Wikimedia pageviews and the end of 2022 for Google Trends.

Questions About timesfm-2.5-200m-pytorch

How much GPU memory does timesfm-2.5-200m-pytorch need?

About 0.6 GB at 16-bit and 0.1 GB at 4-bit: the weights (231M parameters) plus a working margin. A long context needs more.

What is the cheapest GPU to run timesfm-2.5-200m-pytorch 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.

TimesFM (Time Series Foundation Model) is a pretrained decoder-only model for time-series forecasting. This repository contains the Transformers port of the official TimesFM 2.5 PyTorch release. This model is converted from the official TimesFM 2.5 PyTorch checkpoint and integrated into transformers as TimesFm25ModelForPrediction. The converted checkpoint preserves the original architecture and forecasting behavior, including: patch-based inputs for time-series contexts decoder-only self-attention stack point and quantile forecasts Weight conversion parity is verified by comparing converted-model forecasts against the official implementation outputs on deterministic inputs.

Update Feb 14, 2025: Chronos-Bolt models are now available on Amazon SageMaker JumpStart! 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…

PatchTST was originally released prior to the interest in creating pre-trained, zero-shot time series foundation models that were capable of state-of-the-art performance on out of sample datasets. PatchTST-FM (patched time-series transformer-based foundation model) essentially has the architectural simplicity of PatchTST, but differs in some crucial ways. Coupled with a revised training strategy and a significantly larger training corpus, we are able to train a model that achieves state-of-the-art results on GiftEval (see below for recommended filters to view this on the leaderboard). The architecture incorporates the following changes: - residual blocks in the input and output projections…
