文本生成

from generate import OpenAIChat

model = OpenAIChat()
model.generate('你好，GPT！', temperature=0, seed=2023)

# ----- Output -----
ChatCompletionOutput(
    model_info=ModelInfo(task='chat_completion', type='openai', name='gpt-3.5-turbo-0613'),
    cost=0.000343,
    extra={'usage': {'prompt_tokens': 13, 'completion_tokens': 18, 'total_tokens': 31}},
    message=AssistantMessage(
        role='assistant',
        name=None,
        content='你好！有什么我可以帮助你的吗？',
        function_call=None,
        tool_calls=None
    ),
    finish_reason='stop'
)

多模态文本生成

from generate import OpenAIChat

model = OpenAIChat(model='gpt-4-vision-preview')
user_message = {
    'role': 'user',
    'content': [
        {'text': '这个图片是哪里？'},
        {'image_url': {'url': 'https://dashscope.oss-cn-beijing.aliyuncs.com/images/dog_and_girl.jpeg'}},
    ],
}
model.generate(user_message, max_tokens=1000)

# ----- Output -----
ChatCompletionOutput(
    model_info=ModelInfo(task='chat_completion', type='openai', name='gpt-4-1106-vision-preview'),
    cost=0.10339000000000001,
    extra={'usage': {'prompt_tokens': 1120, 'completion_tokens': 119, 'total_tokens': 1239}},
    message=AssistantMessage(
        role='assistant',
        name=None,
        content='这张图片显示的是一名女士和一只狗在沙滩上。他们似乎在享受日落时分的宁静时刻',
        function_call=None,
        tool_calls=None
    ),
    finish_reason='stop'
)

多种调用方式

from generate import OpenAIChat

model = OpenAIChat()
for stream_output in model.stream_generate('介绍一下唐朝'):
    print(stream_output.stream.delta, end='', flush=True)

# 同步调用，model.generate
# 异步调用，model.async_generate
# 流式调用，model.stream_generate
# 异步流式调用，model.async_stream_generate
# 批量调研，model.batch_generate
# 异步批量调用，model.async_batch_generate

派生功能

结构体生成

from generate import OpenAIChat
from pydantic import BaseModel

class Country(BaseModel):
    name: str
    capital: str

model = OpenAIChat().structure(output_structure_type=Country)
model.generate('Paris is the capital of France and also the largest city in the country.')
# ----- Output -----
StructureModelOutput(
    model_info=ModelInfo(task='chat_completion', type='openai', name='gpt-3.5-turbo-0613'),
    cost=0.000693,
    extra={'usage': {'prompt_tokens': 75, 'completion_tokens': 12, 'total_tokens': 87}},
    structure=Country(name='France', capital='Paris')
)

速率限制

import time
from generate import OpenAIChat

# 限制速率，每 10 秒最多 4 次请求
limit_model = OpenAIChat().limit(max_generates_per_time_window=2, num_seconds_in_time_window=10)
start_time = time.time()
for i in limit_model.batch_generate([f'1 + {i} = ?' for i in range(4)]):
    print(i.reply)
    print(f'elapsed time: {time.time() - start_time:.2f} seconds')

# ----- Output -----
1
elapsed time: 0.70 seconds
2
elapsed time: 1.34 seconds
3
elapsed time: 11.47 seconds
4
elapsed time: 12.15 seconds

对话历史保持

from generate import OpenAIChat

session_model = OpenAIChat().session()
session_model.generate('i am bob')
print(session_model.generate('What is my name?').reply)

# ----- Output -----
Your name is Bob.

工具调用

from generate import OpenAIChat, tool

@tool
def get_weather(location: str) -> str:
    return f'{location}, 27°C, Sunny'

agent = OpenAIChat().agent(tools=get_weather)
print(agent.generate('what is the weather in Beijing?').reply)

# ----- Output -----
The weather in Beijing is currently 27°C and sunny.

图像生成模型

    cost=0.56,
    extra={},
    images=[
        GeneratedImage(
            url='https://oaidalleapiprodscus.blob.core.windows.net/...',
            prompt='Visualize an astronomical illustration featuring a black hole at its core. The black hole 
should be portrayed with strong gravitational lensing effect that distorts the light around it. Include a 
surrounding accretion disk, glowing brightly with blue and white hues, streaked with shades of red and orange, 
indicating heat and intense energy. The cosmos in the background should be filled with distant stars, galaxies, and
nebulas, illuminating the vast, infinite space with specks of light.',
            image_format='png',
            content=b'<image bytes>'
        )
    ]
