Related to #32888, but will not fix the issue.
Turns out these assertions are wrong (Not sure if they were correct at
some point).
I tested with this code:
```
request = LanguageModelRequest {
messages: vec![
LanguageModelRequestMessage {
role: Role::User,
content: vec![MessageContent::Text("Give me 10 jokes".to_string())],
cache: false,
},
LanguageModelRequestMessage {
role: Role::Assistant,
content: vec![MessageContent::Text("Sure, here are 10 jokes:".to_string())],
cache: false,
},
],
..request
};
```
The API happily accepted this and Claude proceeded to tell me 10 jokes.
Release Notes:
