Alibaba Model Studio: Context tokens show 0 (prompt_tokens not recognized)
증상
When using Alibaba Model Studio models (e.g., modelstudio/qwen3.5-plus, modelstudio/glm-5), OpenClaw displays 0 context tokens used even during active conversations. The context window size shows correctly, but “used” is always 0.
원인
Input exceeded the model’s maximum context length, causing truncation or a refusal to process the full request. 카테고리: context-window.
해결법
The normalizeUsage() function (lines 9750-9770) already handles this:
const rawInput = asFiniteNumber(raw.input ?? raw.inputTokens ?? raw.input_tokens ?? raw.promptTokens ?? raw.prompt_tokens);
const output = asFiniteNumber(raw.output ?? raw.outputTokens ?? raw.output_tokens ?? raw.completionTokens ?? raw.completion_tokens);
The fix is to call normalizeUsage() before building the usage object.
