**Is your feature request related to a problem? Please describe.**

Some of the Canary changes lead to unreliable use of the `lang_field` slot. There should be a test to check for it in the future for CI integration.

**Describe the solution you'd like**
- Add a CI test to `aed_models` that switches out the `lang_field` and confirms same outputs regardless
- Make this CI test take into account cases where `target_lang` has prompts that are not in the tokenizer.
