We got a similar report here: #9991.

I think we should provide a way to do so, perhaps with a new metadata to indicate that you want "non-strict" behavior.

@Viicos What's the concern with making this the out of the box behavior? That issue says it was rejected by the team because literals "should" be strict, but it's not clear to me why we don't see this as equivalent to the following, where the coercion does work:

class Dice(BaseModel):
    result: Annotated[int, Field(description="The result of a 1d6", ge=1, le=6)] | None = None

I think of the https://en.wikipedia.org/wiki/Robustness_principle, "be conservative in what you send, be liberal in what you accept", and don't see a downside to losslessly coercing strings to ints.
