> **BREAKING:** Simplifies message normalization to single consistent
path, requiring partner package updates
**Key Changes:**
- Consistent multimodal handling:
- OpenAI `image_url` blocks pass through unchanged (broad compatibility)
- OpenAI `input_audio` and `file` blocks convert to v1 standard
equivalents
- Legacy v0 multimodal blocks convert to v1 standard
- Everything else passes through unchanged
- Partner packages must update content block parsing logic
**Partner Updates**
`output_version` affects how messages are serialized into `.content`.
`_normalize_messages()` will now upgrade v0 content to v1, so, all
partners now receive v1 format input regardless of `output_version`.
Migration:
- Partner packages must update to handle v1 input content blocks
- `output_version` still controls serialization format of responses
(unchanged)

The async version of the test should use the `ayield_keys` method
instead of `yield_keys`.
Otherwise tools such as `blockbuster` may trigger on a blocking call.
**Description:**
Fixed corrupted text in the code cell output of the documentation
notebook. The code cell itself was correct, but the saved output
contained garbage text.
**Issue:**
The saved output in the documentation notebook contained garbage/typo
text in the table name.
**Dependencies:**
None
Extensible registry system for translating AI message content blocks
from various model providers. Refactors the way provider-specific
content is handled, moving from hardcoded logic to a plugin-like
architecture.
Having vercel attempt to deploy on each commit (even if unrelated to
docs) was getting annoying. Options:
- `[skip-preview]`
- `[no-preview]`
- `[skip-deploy]`
Full example: `fix(core): resolve memory leak [no-preview]`
Put in `core.utils` this time to prevent other circular import issues
present in the `normalize()` rfc:
`base` imports `content`
`content` imports `ensure_id()` from `base`
re: #32589 cc: @ccurme
- Rename namespace: `messages.content_blocks` -> `messages.content`
- Prefixes and ID logic are now in `messages.common` instead of
`AIMessage` since the logic is shared between messages and message
content. Did this instead of `utils` due to circular import problems
that were hairy
* Create usage metadata on
[`message_delta`](https://docs.anthropic.com/en/docs/build-with-claude/streaming#event-types)
instead of at the beginning. Consequently, token counts are not included
during streaming but instead at the end. This allows for accurate
reporting of server-side tool usage (important for billing)
* Add some clarifying comments
* Fix some outstanding Pylance warnings
* Remove unnecessary `text` popping in thinking blocks
* Also now correctly reports `input_cache_read`/`input_cache_creation`
as a result
