A drop-in base URL change. Nothing in the request shape has to change to get started.

## What is supported

## Unknown fields

Extra body fields are ignored rather than rejected, so a newer SDK cannot break an older route. The `llmeu` block is read from the body and never required.

## Stability promise

The OpenAI shape of `choices` and `usage` is treated as a contract with tests; the `llmeu` block is additive and may gain fields. Removing a field from it would be a breaking change and would be announced in the [changelog](/bg/changelog/).
