`QueryTransformer` Throws "Unsupported parameter: 'temperature'" for Reasoning Models

[dmmrch]

Bug description
When the application is configured with reasoning model, e.g.:

  ai:
    openai:
      chat:
        options:
          model: o3-mini

And we're applying any of available QueryTransformer's – the application throw Unsupported parameter: 'temperature' during Query transform(Query query); phase. This happens because in the following section, QueryTransformer is using default available model, and temperature param is always provided, regardless of the model type

public class CompressionQueryTransformer {
...
	@Override
	public Query transform(Query query) {

...
		var compressedQueryText = this.chatClient.prompt()
			.user(user -> user.text(this.promptTemplate.getTemplate())
				.param("history", formatConversationHistory(query.history()))
				.param("query", query.text()))
			**.options(ChatOptions.builder().temperature(0.0).build())**
			.call()
			.content();
...
	}

}

I thought of making PR with extending ChatOptions by new reasoningEffort param, but I'm not sure if this is a good idea, since it affects all ChatOptions heirs which has no introduced reasoning models yet, e.g. MistralAiChatOptions.

If you suggest what would be the right way to approach this issue – I'd love to submit PR with fix

Environment
Spring AI: tried with 1.0.0-M5 and latest main branch state

Steps to reproduce

1. Configure Spring AI app with reasoning model (e.g. o1 or o3-mini)
2. Apply either of available QueryTransformer's (e.g. CompressionQueryTransformer)
3. Call Query transform(Query query) method of provided QueryTransformer

Expected behavior
Query transform(Query query) should work with reasoning models

Thank you for mentioning this one. Opened a PR to resolve this issue.

As for the reasoningEffort you mentioned, it has been resolved already: #2153
