[bot] Instrument DashScope Python SDK (285,123 weekly downloads)

[braintrust-bot]

Summary

dashscope is Alibaba Cloud's official Python SDK for Model Studio (Bailian), providing direct execution access to Qwen models: text generation, multimodal understanding, embeddings, reranking, and image/video generation. This repo has zero native instrumentation for the dashscope package's own client surface — no integration directory, wrapper, matrix pin, or nox session.

Note: this repo does patch agentscope.model.DashScopeChatModel.__call__ inside the existing AgentScope integration (py/src/braintrust/integrations/agentscope/patchers.py:86-90), but that only covers calls made through AgentScope's own wrapper class. It does not instrument the dashscope SDK's own entrypoints (dashscope.Generation.call(), dashscope.TextEmbedding.call(), etc.), which any user calling DashScope directly (not via AgentScope) would use — that surface is completely untraced.

What needs to be instrumented

• dashscope.Generation.call(model, messages/prompt, ...) — chat/text generation execution, sync and streaming (stream=True generator)
• dashscope.aigc.generation.AioGeneration / async generation variants
• dashscope.TextEmbedding.call(model, input, ...) — embeddings execution
• dashscope.MultiModalConversation.call(...) — multimodal (vision) generation execution
• Response objects expose output, usage (input_tokens, output_tokens) suitable for span metrics; request_id for correlation
