Why the edge:
- Reach, Nanbeige4.2-3B +30: 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…); Nanbeige4.2-3B 85 (Memory 30, the smallest build from Nanbeige is the FP8 repository (the 8-bit GPTQ one is the same size), 5.19 GB, and 5.19 GB × 1.2 = 6.2 GB, within 16 GB.)
- Agent interface, Nanbeige4.2-3B +25: Kronos 60 (Read for a forecasting model, the tool-calling, trained tool calling and structured-output lines stand for what it takes and returns.); Nanbeige4.2-3B 85 (Chat template 20, A Jinja chat template in tokenizer_config.json (7,961 characters), with enable_thinking, preserve_thinking, tools and tool_call_format switche…)
- Documentation and upkeep, Nanbeige4.2-3B +11: Kronos 61 (Model card 11, intended use, architecture, parameters and context are there, limitations, languages and a cut-off aren't.); Nanbeige4.2-3B 72 (Model card 17, Intended use, limitations, the architecture, the parameters (3B outside the embeddings), the context and the languages (in the metadata) are on t…)
- Risk, Nanbeige4.2-3B +5: Kronos 50 (File safety 15, safetensors only, but the only documented loading path is the publisher's Python package in place of a runtime.); Nanbeige4.2-3B 55 (File safety 15, safetensors only, no .bin, .pt or .pth files (25).)
