ShowResponse ValidationError when /api/show omits model_info (cloud models)

Summary

The Ollama Python client raises a Pydantic ValidationError when /api/show responses omit model_info. This happens with some cloud models and breaks downstream tools that call ollama.show() (e.g., llm-ollama).

The llm-ollama maintainer recommended filing this here: https://github.com/taketwo/llm-ollama/issues/65#issue-3760612718

Steps to Reproduce

1. Ensure Ollama server is running.
2. Run: curl -s http://127.0.0.1:11434/api/show -d '{"name":"glm-4.7:cloud"}'

Observed Behavior

Response is valid JSON but missing model_info, and the Python client fails with:

pydantic_core._pydantic_core.ValidationError: 1 validation error for ShowResponse
model_info Field required [type=missing, input_value={...}, input_type=dict]

Example /api/show response (missing model_info)

{"modelfile":"# Modelfile generated by "ollama show"...","template":"{{ .Prompt }}","details":{"parent_model":"","format":"","family":"","families":null,"parameter_size":"","quantization_level":""},"remote_model":"glm-
4.7","remote_host":"https://ollama.com:443","capabilities":["completion","tools","thinking"],"modified_at":"2025-12-
24T10:08:53.438277171-05:00"}

Models observed missing model_info

• glm-4.7:cloud
• qwen3-next:80b-cloud
• deepseek-v3.2:cloud

Other cloud models (e.g., gpt-oss:120b-cloud) return model_info as expected.
