**[1] `gen_ai.operation.name`:** If one of the predefined values applies, but specific system uses a different name it's RECOMMENDED to document it in the semantic conventions for specific GenAI system and use system-specific name in the instrumentation. If a different name is not documented, instrumentation libraries SHOULD use applicable predefined value.

**[2] `gen_ai.request.encoding_formats`:** In some GenAI systems the encoding formats are called embedding types. Also, some GenAI systems only accept a single format per request.

**[3] `gen_ai.system`:** The `gen_ai.system` describes a family of GenAI models with specific model identified
by `gen_ai.request.model` and `gen_ai.response.model` attributes.

The actual GenAI product may differ from the one identified by the client.
Multiple systems, including Azure OpenAI and Gemini, are accessible by OpenAI client
libraries. In such cases, the `gen_ai.system` is set to `openai` based on the
instrumentation's best knowledge, instead of the actual system. The `server.address`
attribute may help identify the actual system in use for `openai`.

For custom model, a custom friendly name SHOULD be used.
If none of these options apply, the `gen_ai.system` SHOULD be set to `_OTHER`.
