UnverifiedOllama通过Modelfile定义模型的配置、系统提示与量化参数，形成可版本化、可分发的模型镜像70% similarUnverifiedOllama does not automatically use the model's full context; the num_ctx parameter must be set manually, as its default value is very small.70% similarUnverifiedA custom Ollama model is essentially a configuration pointing to a base model; the weights remain those of the base model, and only the system prompt and parameters change.68% similarVerifiedOllama is based on the llama.cpp inference engine at its core and natively supports quantized models in GGUF format.68% similar
