model/gen-ai/spans.yaml:171

• It appears there is a typographical error in the attribute name 'gen_ai.provide.name'. To be consistent with the naming convention, it should be 'gen_ai.provider.name'.

      `gen_ai.provide.name` MUST be set to `"azure.ai.inference"` and SHOULD be provided **at span creation time**.

docs/gen-ai/azure-ai-inference.md:58

• The attribute 'gen_ai.provide.name' contains a typo; it should be corrected to 'gen_ai.provider.name' for consistency with the overall change in naming conventions.

`gen_ai.provide.name` MUST be set to `"azure.ai.inference"` and SHOULD be provided **at span creation time**.
