sotalab-llm-metrics
SoTALab 内部 LLM 成本追踪 SDK（Python）。基于 posthog-python，自动按 project/service/env/model 维度上报调用成本到 PostHog，内置价格表（含 cache tokens、Gemini 分段定价）。
安装
pip install sotalab-llm-metrics
# 或按需带上 provider extras
pip install 'sotalab-llm-metrics[openai,anthropic]'
快速使用
Provider 包装（适合单一 SDK client 生命周期）
from llm_metrics import create_anthropic, create_openai, shutdown
anthropic = create_anthropic()
openai = create_openai()
anthropic.messages.create(
model="claude-sonnet-4-6",
max_tokens=1024,
messages=[{"role": "user", "content": "hi"}],
)
shutdown()
track_generation（适合多账号轮转、自定义重试等场景）
from llm_metrics import init, track_generation
init()
# 自己调完 LLM 后手动上报
track_generation(
model="gpt-4o",
provider="azure",
input_tokens=150,
output_tokens=250,
latency_ms=1200,
properties={"account": "azure-02", "job_type": "generate-response"},
)
