    LLM Observability: The OpenAI integration now captures inline base64 images from message content
    as ``image_parts`` on LLM span messages, for both Chat Completions and the Responses API, so
    image inputs render in LLM Observability. This also applies to the OpenAI Agents SDK and to the
    LiteLLM integration, which share the same message extraction. Images referenced by a remote URL
    or ``file_id`` are not fetched and keep their existing text reference. A single inline image
    whose base64 payload exceeds 4 MiB is left as an ``[image omitted: too large]`` marker instead.
    Note that this budget is per image, not per request: several inline images (or an image
    alongside inline audio) can still take a span event past the 5 MB per-event limit, at which
    point the event's input and output are replaced with a placeholder. To stop image bytes from
    being recorded, register a span processor with ``LLMObs.register_processor`` and remove the
    ``image_parts`` key from the messages on ``span.input``.
fixes:
  - |
    LLM Observability: Fixes an issue where an inline base64 image sent in message content to the
    OpenAI Responses API (including through the OpenAI Agents SDK) was recorded as the entire base64
    data URL inside the message text, producing unreadable multi-megabyte span content.
  - |
    LLM Observability: Fixes an issue where an inline base64 image passed as a reusable-prompt
    variable to the OpenAI Responses API was recorded as the entire base64 data URL on the span.
    Such a variable is now recorded as ``[image]``; remote URL and ``file_id`` references are
    unchanged.
  - |
    LLM Observability: Fixes an issue where OpenAI Responses API image-generation results and
    computer-use screenshots were recorded as a stringified dump of the whole response item, which
    embedded the image's base64 payload in the output message. They are now recorded as an
    ``[image]`` marker, or as the screenshot's URL when it is a remote reference.
