GLM 4.7 thinking process not properly formatted - missing leading tags
Description
When using GLM 4.7 model, the thinking process is not being properly formatted. The opening tag (e.g., <think>) at the beginning of the thinking content is missing, causing all reasoning output to appear as plain text in the UI.
Expected Behavior
The thinking process should be wrapped with proper tags like:
<think>
[reasoning content]
</think>
This allows the UI to properly hide/display the thinking content.
Actual Behavior
Only the closing tag is present, or the entire reasoning appears as plain text without any formatting. The opening <think> tag is missing from the beginning of the thinking process.
Steps to Reproduce
- Configure opencode to use GLM 4.7 model (Zhipu AI)
- Ask a question that triggers tool usage or complex reasoning
- Observe the output - the thinking process appears as plain text instead of being properly formatted
Environment
- Model: Zhipu GLM-4.7
- Provider: Custom/Local LLM provider using vLLM or similar
Additional Context
This may be related to how the streaming response is parsed for GLM 4.7, specifically in the JSON parsing logic that handles reasoning_content fields.
