Original GitHub issue: https://github.com/ollama/ollama/issues/3534

What is the issue?

When I ask longer questions, it's about 15K or so. And I've set enough tokens: /set parameter num_ctx 4096. The model outputs a combination of numbers and symbols. Why?

我发现当我在命令行配置【/set parameter num_ctx 4096】 或者在api调用中添加num_ctx 参数时，都会报这个错误，不确定是用法不对，还是这个参数有问题。 不用这个参数就行了。我从结果看上去，即便是用默认值，好像也是没有做截断的(不确定)。
