用法
有关使用 TypeSafe Python SDK 的指南和模式。
调用 System One API
异步同步
import asyncio
from typesafe_sdk import AsyncTypeSafeClient, Choice, Noul, Score
async def main() -> None:
async with AsyncTypeSafeClient() as client:
result = await client.system_one(
"I was charged twice. Please help ASAP.",
{
"billing": Noul(instructions="Is this about billing?"),
"tone": Choice(
instructions="What is the tone?",
criteria={"calm": None, "angry": None},
),
"urgency": Score(
instructions="How urgent is this?",
criteria=["low", "medium", "high"],
),
},
)
print(
result.nouls["billing"].noul,
result.choices["tone"].choice,
result.scores["urgency"].score,
)
asyncio.run(main())from typesafe_sdk import Choice, Noul, Score, TypeSafeClient
client = TypeSafeClient()
state = "I was charged twice. Please help ASAP."
questions = {
"billing": Noul(instructions="Is this about billing?"),
"tone": Choice(
instructions="What is the tone?", criteria={"calm": None, "angry": None}
),
"urgency": Score(
instructions="How urgent is this?", criteria=["low", "medium", "high"]
),
}
result = client.system_one(state, questions)
print(
result.nouls["billing"].noul,
result.choices["tone"].choice,
result.scores["urgency"].score,
)带类型的 system_one 响应
你也可以向 system_one 提供响应模型,使响应的使用更加类型安全:
from typesafe_sdk import Noul, NoulAnswer, SystemOneResponse, TypeSafeClient
class BillingResponse(SystemOneResponse):
billing: NoulAnswer
with TypeSafeClient() as client:
result = client.system_one(
"I was charged twice.",
{"billing": Noul(instructions="Is this about billing?")},
response_model=BillingResponse,
)
assert 0 <= result.billing.noul <= 1
assert result.billing == result.nouls["billing"]
print(result.request_id)自定义响应类型
你也可以定义一个完全不继承自 SystemOneResponse 的全新响应模型:
from pydantic import BaseModel
from typesafe_sdk import Noul, NoulAnswer, TypeSafeClient
class BillingAnswers(BaseModel):
billing: NoulAnswer
class BillingResponse(BaseModel):
answers: BillingAnswers
result = TypeSafeClient().system_one(
"I was charged twice.",
{"billing": Noul(instructions="Is this about billing?")},
response_model=BillingResponse,
)
assert 0 <= result.answers.billing.noul <= 1选择模型
检查可用的模型:
from typesafe_sdk import TypeSafeClient
print(TypeSafeClient().models.list())在创建客户端时选择模型:
client = TypeSafeClient(model="jev")有关详细信息,请参阅 Models 资源参考。
重试
在客户端或每次调用时,将自定义 RetryPolicy 作为 retry 传递。
客户端每次调用
from typesafe_sdk import RetryPolicy, TypeSafeClient
client = TypeSafeClient(retry=RetryPolicy(max_retries=3, backoff_max=0.2, timeout=1.0))from typesafe_sdk import RetryPolicy
client.system_one(
state, questions, retry=RetryPolicy(max_retries=3, backoff_max=0.2, timeout=1.0)
)错误处理
处理 SDK 引发的 异常:
from typesafe_sdk import TypeSafeAPIError
try:
client.system_one(state, questions)
except TypeSafeAPIError as error:
print(error.status, error.request_id)日志记录
SDK 会向日志记录器 typesafe_sdk 记录日志。请根据标准日志记录指南进行配置:
import logging
logging.getLogger("typesafe_sdk").setLevel(logging.DEBUG)或者在导入 SDK 之前将 TYPESAFE_LOG_LEVEL 设置为 debug、info、warning、error 或 off 之一。
info 为每个请求记录一行摘要;debug 还会记录请求和响应的标头及正文。敏感标头(授权、API 密钥、Cookie,以及任何名称包含 token 或 secret 的标头)在日志输出中会被屏蔽。请求和响应正文不会被屏蔽。
环境变量
SDK 读取并使用以下环境变量:
| 变量 | 配置 | 默认值 |
|---|---|---|
TYPESAFE_API_KEY | API 密钥(必需) | — |
TYPESAFE_BASE_URL | API 根 URL | https://api.typesafe.ai |
TYPESAFE_DEFAULT_MODEL | 默认模型 | jev-latest |
TYPESAFE_LOG_LEVEL | typesafe_sdk 记录器级别,在导入时应用一次 | 未设置 |
有关 SDK 默认值,请参阅常量参考。
向前兼容
随着 TypeSafe API 的演变,SDK 将继续正常工作,因此你可以在 SDK 版本发布为其提供一流支持之前采用新的 API 功能。
额外请求字段
使用 extra_body 发送此 SDK 版本之前未包含的请求字段:
from typesafe_sdk import Noul, TypeSafeClient
with TypeSafeClient() as client:
client.system_one(
"I was charged twice.",
{"billing": Noul(instructions="About billing?")},
extra_body={"beam_width": 4},
)原始问题字典
from typesafe_sdk import TypeSafeClient
with TypeSafeClient() as client:
client.system_one(
"I was charged twice.",
{"billing": {"type": "noul", "instructions": "About billing?", "weight": 2}},
)Tip
提示
未知字段是向前兼容的逃生舱。请忽略其类型检查错误,并优先升级 SDK。
未知回答类型
SDK 会记录警告并跳过无法识别的回答类型。使用 raw_http_response 来检查完整的 API 响应,包括这些回答:
from typesafe_sdk import Noul, TypeSafeClient
result = TypeSafeClient().system_one(
"I was charged twice.",
{"billing": Noul(instructions="Is this about billing?")},
)
raw_answers = result.raw_http_response.json()["answers"]未知响应字段
已识别响应上的未知额外字段将被忽略。
