When using Aliyun Bailian (Qwen models) via OpenAI-compatible API, token usage is not correctly tracked in session transcripts. The API returns valid usage data, but OpenClaw records all zeros.

Root Cause

The normalizeUsage() and hasNonzeroUsage() functions in model-selection-CU2b7bN6.js don't support Bailian's field naming conventions:

Bailian API uses:

  • prompt_tokens → should map to input
  • completion_tokens → should map to output
  • total_tokens → should map to total

Current code only checks:

  • input, inputTokens, input_tokens, promptTokens, prompt_tokens
  • But doesn't check nested usage.prompt_tokens

Fix Action

Workaround

Currently using local patch (not sustainable):

  • Modified /dist/model-selection-CU2b7bN6.js directly
  • Works but will be overwritten on next update

PR fix notes

PR #51025: fix(agents): support nested usage object for Bailian API

Description (problem / solution / changelog)

Problem

The Bailian (Aliyun) API via OpenAI-compatible mode returns usage data in a nested 'usage' object with field names like 'prompt_tokens', 'completion_tokens', and 'total_tokens'. This was not being normalized, resulting in zero token usage tracking.

Solution

  • Update normalizeUsage() to check for nested usage object
  • Update hasNonzeroUsage() to detect nested usage fields
  • Add 'usage' property to UsageLike type definition
  • Add test cases for Bailian-style nested usage

Testing

Added test cases to verify normalization of nested usage objects.

Fixes #51004

Changed files

  • src/agents/usage.normalization.test.ts (modified, +18/-0)
  • src/agents/usage.ts (modified, +23/-5)

Description

When using Aliyun Bailian (Qwen models) via OpenAI-compatible API, token usage is not correctly tracked in session transcripts. The API returns valid usage data, but OpenClaw records all zeros.

API Response (Verified Working)

{
  "usage": {
    "total_tokens": 30,
    "completion_tokens": 8,
    "prompt_tokens": 22,
    "prompt_tokens_details": {
      "cached_tokens": 0
    }
  }
}

Transcript Record (Incorrect)

{
  "message": {
    "usage": {
      "input": 0,
      "output": 0,
      "cacheRead": 0,
      "cacheWrite": 0,
      "totalTokens": 0
    }
  }
}

Root Cause

The normalizeUsage() and hasNonzeroUsage() functions in model-selection-CU2b7bN6.js don't support Bailian's field naming conventions:

Bailian API uses:

  • prompt_tokens → should map to input
  • completion_tokens → should map to output
  • total_tokens → should map to total

Current code only checks:

  • input, inputTokens, input_tokens, promptTokens, prompt_tokens
  • But doesn't check nested usage.prompt_tokens

Proposed Fix

1. Update normalizeUsage() function

function normalizeUsage(raw) {
	if (!raw) return;
	// Support nested usage object (e.g., Bailian API via OpenAI-compatible mode)
	const usageObj = raw.usage ?? raw;
	const rawInput = asFiniteNumber(
    raw.input ?? raw.inputTokens ?? raw.input_tokens ?? 
    raw.promptTokens ?? raw.prompt_tokens ?? 
    usageObj.prompt_tokens  // ← Add this
  );
	const input = rawInput !== void 0 && rawInput < 0 ? 0 : rawInput;
	const output = asFiniteNumber(
    raw.output ?? raw.outputTokens ?? raw.output_tokens ?? 
    raw.completionTokens ?? raw.completion_tokens ?? 
    usageObj.completion_tokens  // ← Add this
  );
	const cacheRead = asFiniteNumber(
    raw.cacheRead ?? raw.cache_read ?? raw.cache_read_input_tokens ?? 
    raw.cached_tokens ?? raw.prompt_tokens_details?.cached_tokens ?? 
    usageObj.cached_tokens  // ← Add this
  );
	const cacheWrite = asFiniteNumber(
    raw.cacheWrite ?? raw.cache_write ?? raw.cache_creation_input_tokens ?? 
    usageObj.cache_creation_input_tokens  // ← Add this
  );
	const total = asFiniteNumber(
    raw.total ?? raw.totalTokens ?? raw.total_tokens ?? 
    usageObj.total_tokens  // ← Add this
  );
	if (input === void 0 && output === void 0 && cacheRead === void 0 && cacheWrite === void 0 && total === void 0) return;
	return { input, output, cacheRead, cacheWrite, total };
}

2. Update hasNonzeroUsage() function

function hasNonzeroUsage(usage) {
	if (!usage) return false;
	// Support nested usage object (e.g., Bailian API via OpenAI-compatible mode)
	const usageObj = usage.usage ?? usage;
	return [
		usage.input,
		usage.output,
		usage.cacheRead,
		usage.cacheWrite,
		usage.total,
		usageObj.prompt_tokens,      // ← Add this
		usageObj.completion_tokens,  // ← Add this
		usageObj.total_tokens        // ← Add this
	].some((v) => typeof v === "number" && Number.isFinite(v) && v > 0);
}

Environment

  • OpenClaw version: 2026.3.13
  • Provider: Aliyun Bailian (Model Studio)
  • Base URL: https://coding.dashscope.aliyuncs.com/v1
  • Models affected: qwen3.5-plus, qwen-plus, and all Qwen series via OpenAI-compatible API

Impact

  • Cannot track token usage for Bailian provider
  • Cannot implement context limit monitoring (80% threshold warnings)
  • Cannot implement session checkpoint/compression based on actual token usage

Workaround

Currently using local patch (not sustainable):

  • Modified /dist/model-selection-CU2b7bN6.js directly
  • Works but will be overwritten on next update

Request

Please consider:

  1. Adding support for nested usage object field mapping
  2. Adding Bailian-specific field names to the normalization logic
  3. Optionally: Add provider-specific usage mapping configuration

Additional Context

This issue affects all providers using OpenAI-compatible API with non-standard usage field naming. Bailian is just one example - there may be other providers with similar issues.

Happy to test patches or provide more API response examples if needed!

Fix Plan

To fix the issue with token usage tracking in OpenClaw for Aliyun Bailian (Qwen models) via OpenAI-compatible API, follow these steps:

  1. Update the normalizeUsage() function:

    • Modify the normalizeUsage() function in model-selection-CU2b7bN6.js to support nested usage object field mapping.
    • Add Bailian-specific field names to the normalization logic.

  2. Update the hasNonzeroUsage() function:

    • Modify the hasNonzeroUsage() function to support checking for nonzero usage in the nested usage object.

Code Changes

The proposed fix involves updating two functions: normalizeUsage() and hasNonzeroUsage(). The updated code snippets are provided below:

Updated normalizeUsage() Function

function normalizeUsage(raw) {
  if (!raw) return;
  const usageObj = raw.usage ?? raw;
  const rawInput = asFiniteNumber(
    raw.input ?? raw.inputTokens ?? raw.input_tokens ?? 
    raw.promptTokens ?? raw.prompt_tokens ?? 
    usageObj.prompt_tokens
  );
  const input = rawInput !== void 0 && rawInput < 0 ? 0 : rawInput;
  const output = asFiniteNumber(
    raw.output ?? raw.outputTokens ?? raw.output_tokens ?? 
    raw.completionTokens ?? raw.completion_tokens ?? 
    usageObj.completion_tokens
  );
  const cacheRead = asFiniteNumber(
    raw.cacheRead ?? raw.cache_read ?? raw.cache_read_input_tokens ?? 
    raw.cached_tokens ?? raw.prompt_tokens_details?.cached_tokens ?? 
    usageObj.cached_tokens
  );
  const cacheWrite = asFiniteNumber(
    raw.cacheWrite ?? raw.cache_write ?? raw.cache_creation_input_tokens ?? 
    usageObj.cache_creation_input_tokens
  );
  const total = asFiniteNumber(
    raw.total ?? raw.totalTokens ?? raw.total_tokens ?? 
    usageObj.total_tokens
  );
  if (input === void 0 && output === void 0 && cacheRead === void 0 && cacheWrite === void 0 && total === void 0) return;
  return { input, output, cacheRead, cacheWrite, total };
}

Updated hasNonzeroUsage() Function

function hasNonzeroUsage(usage) {
  if (!usage) return false;
  const usageObj = usage.usage ?? usage;
  return [
    usage.input,
    usage.output,
    usage.cacheRead,
    usage.cacheWrite,
    usage.total,
    usageObj.prompt_tokens,
    usageObj.completion_tokens,
    usageObj.total_tokens
  ].some((v) => typeof v === "number" && Number.isFinite(v) && v > 0);
}
