SAVRN's Notes on chronos-bolt-small
Forty-eight million parameters and 0.1 GB of memory at 16-bit: that is the whole of Amazon's chronos-bolt-small, a T5 encoder-decoder trained on nearly 100 billion time series observations for zero-shot forecasting. The cheapest listed setup, one 192 GB MI300X at $1.85 per hour on-demand, would carry it as a sliver. Nobody rents a card for this alone; put it beside work already filling a GPU, or run many copies.
Apache 2.0 permits commercial use, modification and redistribution, provided the license and copyright notices and any NOTICE file travel with the weights and significant changes are stated; the patent grant matters once it ships in a product. Before committing, ask how long a history it accepts, since the page lists no token context length and the model reads history as patches of observations. The publisher also offers a hosted SageMaker JumpStart endpoint; choose that or your own GPU hour.
