Original GitHub issue: https://github.com/ollama/ollama/issues/6887

reader-lm converts HTML to Markdown but with the default temperature, it hallucinates content: https://github.com/ollama/ollama/issues/6875. Setting temperature to zero appears to resolve this. This would be nice to have in the model config in the ollama library.

@rick-github were you able to get reader-lm to respond when setting temperature?

I can get reader-lm to respond when I dont set temperature, but as soon as I add the temperature parameter to the request my client freezes and ollama seeming never responds or never completes it's response, super strange. I've tested my setup with many other ollama models no problemo, so I don't think the issue is on the client side.

Weirdly, the 0.5b version works, no other changes besides changing the model parameter between :latest and :0,5b

Failing / never-ending payload:

{
	"messages": [
		{
			"content": "<meta property=\"og:description\" content=\"Introducing the FeatherS3 -&amp;nbsp;The pro ESP32-S3 Development Board in the Feather Format now with a u.FL connector&amp;nbsp;instead of an onboard antenna, for the times when you want to connect ...\">",
			"role": "user"
		}
	],
	"model": "reader-lm:latest",
	"options": {
		"temperature": 0
	},
	"stream": false
}

Working payload #1 (only model change)

{
	"messages": [
		{
			"content": "<meta property=\"og:description\" content=\"Introducing the FeatherS3 -&amp;nbsp;The pro ESP32-S3 Development Board in the Feather Format now with a u.FL connector&amp;nbsp;instead of an onboard antenna, for the times when you want to connect ...\">",
			"role": "user"
		}
	],
	"model": "reader-lm:0.5b",
	"options": {
		"temperature": 0
	},
	"stream": false
}

Working payload #2 (only remove temperature):

{
	"messages": [
		{
			"content": "<meta property=\"og:description\" content=\"Introducing the FeatherS3 -&amp;nbsp;The pro ESP32-S3 Development Board in the Feather Format now with a u.FL connector&amp;nbsp;instead of an onboard antenna, for the times when you want to connect ...\">",
			"role": "user"
		}
	],
	"model": "reader-lm:latest",
	"options": {

	"stream": false
}
