Kronos scores 55.2 (C) on agent readiness against LongCat-2.5's 50.5 (D), and leads in 2 of 4 scored categories. LongCat-2.5 leads on risk and agent interface. Both do open-weight models you run yourself.

- Kronos: C 55.2, rank #122 of 160 open-weight models · https://www.anchorterminal.com/tools/kronos.min.md
- LongCat-2.5: D 50.5, rank #145 of 160 open-weight models · https://www.anchorterminal.com/tools/longcat-2-5.min.md
- Kronos, good for Agents that need a quick local forecast or synthetic sample of a candlestick series on modest hardware, for research or as one input among others. Ahead on Reach, 55 against 35; Documentation and upkeep, 61 against 46.
- LongCat-2.5, good for Operators with NPU clusters, and anyone tracking what the open flagships can do Ahead on Risk, 60 against 50; Agent interface, 75 against 60.

Why the edge:
- Reach, Kronos +20: Kronos 55 (Memory 30, the publisher's Kronos-mini with its tokeniser is 0.03 GB and even Kronos-base is 0.43 GB in FP32. Runtimes 0, it runs only through the publisher's o…); LongCat-2.5 35 (Memory 0, the smallest build is Meituan's W4A4 repository, 1,336 GB, and 1,336 GB × 1.2 = 1,603 GB, far above 256 GB.)
- Agent interface, LongCat-2.5 +15: Kronos 60 (Read for a forecasting model, the tool-calling, trained tool calling and structured-output lines stand for what it takes and returns.); LongCat-2.5 75 (Chat template 20, chat_template.jinja in the repository (11,823 characters), with a copy in tokenizer_config.json.)
- Documentation and upkeep, Kronos +15: Kronos 61 (Model card 11, intended use, architecture, parameters and context are there, limitations, languages and a cut-off aren't.); LongCat-2.5 46 (Model card 11, Intended use, limitations (the usage considerations), the architecture and the parameter counts are on the card.)
- Risk, LongCat-2.5 +10: Kronos 50 (File safety 15, safetensors only, but the only documented loading path is the publisher's Python package in place of a runtime.); LongCat-2.5 60 (File safety 25, safetensors only, no .bin, .pt or .pth files and no Python in the repository.)
