/api/showmarshalsOllamaCapabilitiesModelInfodirectly, butIDhas no JSON tag, so the response key is emitted as"ID"instead of a lowercase/snake_case API key. Clients that deserialize the show payload using Ollama-style field names (or strict schemas) will not see this identifier field, which can break model metadata parsing even though the endpoint returns 200.Useful? React with 👍 / 👎.
