我上传了文件让模型分析却总是不按照我的要求去分析，后来看了思考过程发现是模型根本不知道我的提示词在猜测我要怎么分析并给出结果。我用硅基流动的同款模型测试了一下发现完全正常，这似乎是ollama的问题，因为我测试了ollama上几个模型都是这样。

Have you set the context length?

<!-- gh-comment-id:2869154526 --> @rick-github commented on GitHub (May 10, 2025): Have you set the [context length](https://github.com/ollama/ollama/blob/main/docs/faq.md#how-can-i-specify-the-context-window-size)?

I tried to set the OLLAMA_CONTEXT_LENGTH parameter but the result is the same

我找到问题的原因了，确实是文件大小超过了上下文的限制导致的，OLLAMA_CONTEXT_LENGTH这个参数必须要重启电脑后才能生效，单纯重启软件没用的。
造成这种情况的原因是ollama是从尾部往前读取的，我看到结果中引用了文档尾部的内容所以觉得ollama应该把文档都读取完了，其实只读取了文档尾部的内容，文档前部和提示词都没读取到。
