+# chronos-2 — ONNX checkpoints
+
+ONNX export of [`amazon/chronos-2`](https://huggingface.co/amazon/chronos-2) for
+[OpenSTEF](https://github.com/OpenSTEF/openstef), produced by
+[`openstef-checkpoints`](https://github.com/OpenSTEF/openstef-checkpoints).
+
+OpenSTEF resolves these via `HubCheckpoint`; the metadata file next to each weights file drives the
+inference path. Each variant was checked against the torch reference on representative inputs before
+publishing.
+
+## Variants
+
+| File | Precision | Static shapes | Max deviation vs torch |
+|---|---|---|---|
+| `chronos-2_static.onnx` | fp32 | yes | 1.788e-07 |
+| `chronos-2.onnx` | fp32 | no | 2.98e-08 |
+| `chronos-2_int8.onnx` | int8 | no | 9.677e-05 |
+
+
+Pick by deployment target: **static fp32** is the portable, CoreML-eligible default; **int8** for size;
+**dynamic** when context/horizon must vary.
+
+## Provenance
+
+- Source model: `amazon/chronos-2` @ `unknown`
+- Exporter: `openstef-checkpoints` @ `f1ea4ab27067a7ce8b8ec79d6dd0ae9656428e11`
+- Tooling: onnx=1.22.0 onnxruntime=1.27.0 torch=2.12.1+cpu
+- Exported: 2026-06-19T11:18:21+00:00
+
+## License and attribution
+
+These ONNX checkpoints are derived from
+[`amazon/chronos-2`](https://huggingface.co/amazon/chronos-2) and released under the same
+license, **apache-2.0**. Attribution and all rights to the model weights remain with the
+upstream authors; if you use the model in research, please cite their work.
+
+**Modifications.** The original weights were converted from PyTorch to ONNX and exported in several
+shape and precision variants (static or dynamic shapes; fp32, fp16, or int8). The weights were not
+retrained, fine-tuned, or otherwise altered.
+
+The tooling that produced these files
+([`openstef-checkpoints`](https://github.com/OpenSTEF/openstef-checkpoints)) is licensed MPL-2.0,
+which does not extend to the weights.
