Quick Start

from sagellm_protocol import Request, Response, Metrics, ErrorCode

# 创建请求
req = Request(
    request_id="req-001",
    trace_id="trace-001",
    model="llama2-7b",
    prompt="Hello, world!",
    max_tokens=128,
    stream=False,
    temperature=0.7,
)

# 创建响应
metrics = Metrics(
    ttft_ms=45.2,
    tbt_ms=12.5,
    throughput_tps=80.0,
    peak_mem_mb=24576,
    error_rate=0.0,
)

resp = Response(
    request_id="req-001",
    trace_id="trace-001",
    output_text="Hi there!",
    output_tokens=[42, 17],
    finish_reason="stop",
    metrics=metrics,
)
