Notes

200M params, up to 16k context (README). The -transformers repo is a conversion of the PyTorch checkpoint; the -flax card has no content beyond the license. GIFT-Eval's results config for TimesFM-2.5 sets "testdata_leakage": "No". The card does not mention the M4/Electricity/Traffic/Weather/LibCity/Favorita data of 1.0 or the LOTSA subset of 2.0.
