説明
1. Anthropic (Streaming)
When using agent-workflow with Anthropic and stream = true, the usage info is filtered out from the chunk.
The usage info is of type "message-delta", and the chunk is not yielded in the code below:
🔗 LlamaIndexTS Anthropic LLM Code
Example payload:
{
"type": "message_delta",
"delta": {
"stop_reason": "end_turn",
"stop_sequence": null
},
"usage": {
"input_tokens": 8,
"cache_creation_input_tokens": 0,
"cache_read_input_tokens": 0,
"output_tokens": 12
}
}
2. Anthropic and OpenAI (Non-Streaming)
When running with agent.run, it is returning the finalEvent.
However, the finalEvent does not have usage info applicable.
