0. 背景

大约两个月前有一份新闻稿。

https://www.oracle.com/news/announcement/oracle-to-deliver-powerful-and-secure-generative-ai-service-for-business-2023-06-13/

Oracle 计划与为企业提供人工智能平台的 Cohere 合作，在 OCI 上提供新的生成式人工智能服务。

请注意，对于可以免费使用的试用密钥，严格设置了速率限制和执行总数。

Trial Key Limitations

1. Cohere提供的模型和函数

• Command

  • 提供文本生成模型
  • 学会遵循用户命令

• Embeddings

  • 提供 Embedding 模型
  • 多言语対応

此外，所提供的功能在 API 参考中进行了描述，但除非在某些等待列表中注册才能使用的功能除外。

API endpoint	概述
/generate	给定输入，生成真实文本并返回
/embed	对文本进行 Embedding 并返回浮点列表
/classify	判断哪个标签与输入文本匹配并返回结果
/tokenize	将输入文本转换分为 token 并返回结果
/detokenize	接收 BPE（byte-pair encoding）token 并返回其文本表示形式
/detect-language	识别输入文本是用哪种语言编写的并返回结果
/summarize	为输入文本创建英文摘要并返回结果
/rerank	接受查询和文本列表，生成并返回一个有序数组，其中每个文本都分配有一个关联的分数

2. Cohere 客户端

Cohere 还有一个异步客户端，但这次我们将使用同步客户端，因为我们只是测试功能。

代码示例，

import cohere
api_key = '<your-api-key>'co = cohere.Client(api_key)
co.check_api_key()

3. Co.Generate API

仅指定最少的必要参数并尝试执行。

示例代码，

res_generate = co.generate(prompt='Hello, how'
)print(res_generate)

输出结果，

[cohere.Generation {id: 905bc1fa-cb5a-4082-b1d8-2704d426956bprompt: Hello, howtext:  How can I help you?likelihood: Nonefinish_reason: Nonetoken_likelihoods: None
}]

它生成了文本 “How can I help you?”？

还有其他参数允许您选择模型（model）、要生成的文本数量、文本中的最大标记数量等等。以下是我尝试过的一些示例。

示例：使用 Nightly 版本生成 3 个包含最多 50 个标记的文本

示例代码，

res_generate = co.generate(prompt='Hello, how',model='command-nightly',num_generations=3,max_tokens=50
)print(res_generate)

输出结果，

[cohere.Generation {id: 8eca3fb0-9a9b-4df2-997d-e5fba22ebfbbprompt: Hello, howtext:  can I help you?likelihood: Nonefinish_reason: Nonetoken_likelihoods: None
}, cohere.Generation {id: 2b5d7382-64cb-48a8-8bb0-33c574565defprompt: Hello, howtext:  Hello! I'm a chatbot trained to be helpful and harmless. How can I assist you today?likelihood: Nonefinish_reason: Nonetoken_likelihoods: None
}, cohere.Generation {id: 060903ac-241f-4a9f-bd46-32de661a0799prompt: Hello, howtext:  are you doing today?likelihood: Nonefinish_reason: Nonetoken_likelihoods: None
}]

示例：仅考虑前 5 个最可能的标记 (k=5) 进行生成并最大化生成中的随机性 (temperature=5.0)

示例代码，

res_generate = co.generate(prompt='Hello, how',model='command-nightly',num_generations=3,max_tokens=50,k=5,temperature=5.0
)print(res_generate)

输出结果，

[cohere.Generation {id: 55f7482c-70ef-4846-be70-34af13df268aprompt: Hello, howtext:  are you ?likelihood: Nonefinish_reason: Nonetoken_likelihoods: None
}, cohere.Generation {id: d9286b01-bd12-4563-839b-6cf867f69873prompt: Hello, howtext:  I’d like to thank the user.  Is this how they would prefer me to address them?  If so I can change that to their username.
How may I be of service?  If I can help with any tasks Ilikelihood: Nonefinish_reason: Nonetoken_likelihoods: None
}, cohere.Generation {id: 6a2472a8-2663-4b83-a988-f164d1254707prompt: Hello, howtext:  can I help you with something, or provide any assistance?likelihood: Nonefinish_reason: Nonetoken_likelihoods: None
}]

示例：以 JSON 流的形式接收生成的结果（对于增量呈现响应内容的 UI 似乎很有用）

示例代码，

res_generate_streaming = co.generate(prompt='Hello, how',stream=True
)for index, token in enumerate(res_generate_streaming):print(f"{index}: {token}")res_generate_streaming.texts

输出结果，

0: StreamingText(index=0, text=' Hello', is_finished=False)
1: StreamingText(index=0, text='!', is_finished=False)
2: StreamingText(index=0, text=' How', is_finished=False)
3: StreamingText(index=0, text=' can', is_finished=False)
4: StreamingText(index=0, text=' I', is_finished=False)
5: StreamingText(index=0, text=' help', is_finished=False)
6: StreamingText(index=0, text=' you', is_finished=False)
7: StreamingText(index=0, text=' today', is_finished=False)
8: StreamingText(index=0, text='?', is_finished=False)
[' Hello! How can I help you today?']

其他详细信息请参阅API参考 - Co.Generate。

4. Co.Embed API

仅指定最少的必要参数并尝试执行。

示例代码，

res_embed = co.embed(texts=['hello', 'world']
)print(res_embed)

输出结果（部分省略），

cohere.Embeddings {embeddings: [[1.6142578, 0.24841309, 0.5385742, -1.6630859, -0.27783203, 0.35888672, 1.3378906, -1.8261719, 0.89404297, 1.0791016, 1.0566406, 1.0664062, 0.20983887, ... , -2.4160156, 0.22875977, -0.21594238]]compressed_embeddings: []meta: {'api_version': {'version': '1'}}
}

返回嵌入的结果。另外，在Embedding函数中，可以将要使用的模型指定为参数。

示例：尝试使用轻型版本模型 (model=embed-english-light-v2.0)

示例代码，

res_embed = co.embed(texts=['hello', 'world'],model='embed-english-light-v2.0'
)print(res_embed)

输出结果（部分省略），

cohere.Embeddings {embeddings: [[-0.16577148, -1.2109375, 0.54003906, -1.7148438, -1.5869141, 0.60839844, 0.6328125, 1.3974609, -0.49658203, -0.73046875, -1.796875, 1.5410156, 0.66064453, 0.9448242, -0.53515625, 0.24914551, 0.53222656, 0.23425293, 0.52685547, -1.3935547, 0.04095459, 0.8569336, -0.5620117, -0.42211914, 0.55371094, 3.5820312, 7.2890625, -1.2539062, 1.3583984, 0.12988281, -1.1660156, 0.124816895, ... ,0.87060547, 1.0205078, 0.5854492, -2.734375, -0.066589355, 1.8349609, 0.16430664, -0.26220703, -1.0625]]compressed_embeddings: []meta: {'api_version': {'version': '1'}}
}

示例：尝试使用多语言模型 (model=embed-multilingual-v2.0)

示例代码，

res_embed = co.embed(texts=['こんにちは', '世界'],model='embed-multilingual-v2.0'
)print(res_embed)

输出结果（部分省略），

cohere.Embeddings {embeddings: [[0.2590332, 0.41308594, 0.24279785, 0.30371094, 0.04647827, 0.1361084, 0.41357422, -0.40063477, 0.2553711, 0.17749023, -0.1899414, -0.041900635, 0.20141602, 0.43017578, -0.5878906, 0.18054199, 0.42333984, 0.010749817, -0.56640625, 0.1517334, 0.14282227, 0.36767578, 0.26953125, 0.1418457, 0.28051758, 0.1661377, -0.13293457, 0.23620605, 0.08703613, 0.36914062, 0.22180176, ... ,0.027786255, -0.18530273, -0.24414062, 0.123168945, 0.6425781, 0.08831787, -0.21862793, -0.18237305, -0.031341553]]compressed_embeddings: []meta: {'api_version': {'version': '1'}}
}

其他详细信息请参阅 API 参考 - Co.Embed。

5. Co.Classify API

仅指定最少的必要参数并尝试执行。

示例代码，

from cohere.responses.classify import Exampleexamples=[Example("Dermatologists don't like her!", "Spam"),Example("'Hello, open to this?'", "Spam"),Example("I need help please wire me $1000 right now", "Spam"),Example("Nice to know you ;)", "Spam"),Example("Please help me?", "Spam"),Example("Your parcel will be delivered today", "Not spam"),Example("Review changes to our Terms and Conditions", "Not spam"),Example("Weekly sync notes", "Not spam"),Example("'Re: Follow up from today's meeting'", "Not spam"),Example("Pre-read for tomorrow", "Not spam"),
]inputs=["Confirm your email address","hey i need u to send some $",
]res_classify = co.classify(inputs=inputs,examples=examples,
)print(res_classify)

输出结果，

[Classification<prediction: "Not spam", confidence: 0.5661598, labels: {'Not spam': LabelPrediction(confidence=0.5661598), 'Spam': LabelPrediction(confidence=0.43384025)}>, Classification<prediction: "Spam", confidence: 0.9909811, labels: {'Not spam': LabelPrediction(confidence=0.009018883), 'Spam': LabelPrediction(confidence=0.9909811)}>]

“Confirm your email address”，可能是垃圾邮件，也可能不是垃圾邮件，因此 Not spam: 0.56…, Spam: 0.43… 似乎合适。
“hey i need u to send some $”，听起来很垃圾邮件，但确实如此（ Spam: 0.99, Not spam: 0.009 ）。

在分类函数中，您可以指定其他参数来指定模型和截断（如何处理长于最大标记长度的输入）。

示例：当传递的输入长度超过轻量级模型 (model=embed-english-light-v2.0) 中的最大令牌长度时，返回错误 (truncate=NONE)

示例代码，

当我给最多只能传递 96 个输入的输入提供 136 个输入时，它返回错误。

有关更多详细信息，请参阅 API 参考 - Co.Classify。

6. Co.Tokenize API

仅指定最少的必要参数并尝试执行。

示例代码，

res_tokenize = co.tokenize(text='tokenize me !D',
)print(res_tokenize)

输出结果，

cohere.Tokens {tokens: [10002, 2261, 2012, 3362, 43]token_strings: ['token', 'ize', ' me', ' !', 'D']meta: {'api_version': {'version': '1'}}
}

除此之外，还有选择模型的参数，但即使参考API参考 - Co.Tokenize，除了 command 之外还可以选择什么，我也不太明白。

7. Co.Detokenize API

仅指定最少的必要参数并尝试执行。

示例代码，

tokens = [10002, 2261, 2012, 3362, 43] # tokenize me !Dres_detokenize = co.detokenize(tokens=tokens
)print(res_detokenize)

输出结果，

tokenize me !D

除此之外，还有选择模型的参数，但是即使参考API Reference - Co.Detokenize，我也不太明白除了 command 之外还可以选择什么。

8. Co.Detect_language

仅指定最少的必要参数并尝试执行。

示例代码，

res_detect_language = co.detect_language(texts=['Hello world', "'Здравствуй, Мир'", 'こんにちは世界', '世界你好', '안녕하세요']
)res_detect_language

输出结果，

cohere.DetectLanguageResponse {results: [Language<language_code: "en", language_name: "English">, Language<language_code: "ru", language_name: "Russian">, Language<language_code: "ja", language_name: "Japanese">, Language<language_code: "zh", language_name: "Chinese">, Language<language_code: "ko", language_name: "Korean">]meta: {'api_version': {'version': '1'}}
}

看来检测正确。 Detect_language 没有其他可以指定的参数。

9. Co.Summarize API

仅指定最少的必要参数并尝试执行。

示例代码，

text = ("Ice cream is a sweetened frozen food typically eaten as a snack or dessert. ""It may be made from milk or cream and is flavoured with a sweetener, ""either sugar or an alternative, and a spice, such as cocoa or vanilla, ""or with fruit such as strawberries or peaches. ""It can also be made by whisking a flavored cream base and liquid nitrogen together. ""Food coloring is sometimes added, in addition to stabilizers. ""The mixture is cooled below the freezing point of water and stirred to incorporate air spaces ""and to prevent detectable ice crystals from forming. The result is a smooth, ""semi-solid foam that is solid at very low temperatures (below 2 °C or 35 °F). ""It becomes more malleable as its temperature increases.\n\n""The meaning of the name \"ice cream\" varies from one country to another. ""In some countries, such as the United States, \"ice cream\" applies only to a specific variety, ""and most governments regulate the commercial use of the various terms according to the ""relative quantities of the main ingredients, notably the amount of cream. ""Products that do not meet the criteria to be called ice cream are sometimes labelled ""\"frozen dairy dessert\" instead. In other countries, such as Italy and Argentina, ""one word is used fo\r all variants. Analogues made from dairy alternatives, ""such as goat's or sheep's milk, or milk substitutes ""(e.g., soy, cashew, coconut, almond milk or tofu), are available for those who are ""lactose intolerant, allergic to dairy protein or vegan."
)co_summarize = co.summarize(text=text
)print(co_summarize)

输出结果，

输出结果(机器翻译)，

冰淇淋是一种冷冻食品，通常作为零食或甜点食用。它由牛奶或奶油制成，并用甜味剂和香料或水果调味。它也可以通过将调味奶油基料和液氮搅拌在一起来制成。可以添加食用色素和稳定剂。将混合物冷却并搅拌以加入空气空间并防止冰晶形成。最终形成光滑的半固态泡沫，在低温下呈固态。随着温度升高，它变得更具延展性。 “冰淇淋”这个名字的含义因国家而异。一些国家，例如美国，对“冰淇淋”一词的商业使用有具体规定。不符合冰淇淋标准的产品有时会被贴上“冷冻乳制品甜点”的标签。乳糖不耐症或对乳蛋白过敏的人可以选择乳制品替代品，例如山羊奶或绵羊奶或牛奶替代品。

看来总结得很好。除此之外，你还可以指定输出摘要的长度（length）、输出格式（format）以及摘要时从原始文本中提取多少内容。似乎可以指定（提取性）等参数。以下是我尝试过的一些示例。

示例：缩短长度（length=short）并以项目符号格式输出（format=bullets）

示例代码，

co_summarize = co.summarize(text=text,length='short',format='bullets'
)print(co_summarize)

输出结果，

SummarizeResponse(id='fefca5fe-1dd4-4fff-91b0-622fc9fc64ec', summary='- Ice cream is a frozen dessert made from milk or cream.\n- It is flavored with a sweetener and a spice or fruit.\n- It can also be made with dairy alternatives.', meta={'api_version': {'version': '1'}})

输出结果(机器翻译)，

冰淇淋是一种由牛奶或奶油制成的冷冻甜点。
它用甜味剂和香料或水果调味。
它也可以用乳制品替代品制成。

示例：使用模型的轻型版本（model=command-light），从原始文本中提取更多内容（extractiveness=high），并以项目符号形式输出。

示例代码，

co_summarize = co.summarize(text=text,model='command-light',length='short',format='bullets',extractiveness='high'
)print(co_summarize)

输出结果，

SummarizeResponse(id='df22373b-dd85-4b8f-a6c4-0aac6db32898', summary='- Ice cream is a sweetened frozen food typically eaten as a snack or dessert.\n- It may be made from milk or cream and is flavored with a sweetener, either sugar or an alternative.\n- It can also be made by whisking a flavored cream base and liquid nitrogen together.\n- The result is a smooth, semi-solid foam that is solid at very low temperatures.\n- It becomes more malleable as its temperature increases.\n- The meaning of the name varies from one country to another.', meta={'api_version': {'version': '1'}})

输出结果(机器翻译)，

冰淇淋是一种加糖的冷冻食品，通常作为零食或甜点食用。
它可以由牛奶或奶油制成，并用甜味剂（糖或替代品）调味。
它也可以通过将调味奶油基料和液氮搅拌在一起来制成。
其结果是形成光滑的半固态泡沫，在极低的温度下呈固态。
随着温度升高，它变得更具延展性。
名称的含义因国家而异。

当然，从原始句子中提取更多内容（例如，冰淇淋是一种加糖的冷冻食品，通常作为零食或甜点食用。）

其他详细信息请参阅 API 参考 - (Co.Summarize](https://docs.cohere.com/reference/summarize-2)。

10. Co.Rerank API

仅指定最少的必要参数并尝试执行。

示例代码，

docs = ['Carson City is the capital city of the American state of Nevada.','The Commonwealth of the Northern Mariana Islands is a group of islands in the Pacific Ocean. Its capital is Saipan.','Washington, D.C. (also known as simply Washington or D.C., and officially as the District of Columbia) is the capital of the United States. It is a federal district.','Capital punishment (the death penalty) has existed in the United States since beforethe United States was a country. As of 2017, capital punishment is legal in 30 of the 50 states.'
]co_rerank = co.rerank(model='rerank-english-v2.0',query='What is the capital of the United States?',documents=docs
)print(co_rerank)

根据API Reference - Co.Rerank，model的参数不是必需的，但是当它在没有分配 TypeError: rerank() missing 1 required positional argument: ‘model’ 的情况下执行并输出错误日志时，它似乎是必需的参数。当心。

输出结果，

[RerankResult<document['text']: Washington, D.C. (also known as simply Washington or D.C., and officially as the District of Columbia) is the capital of the United States. It is a federal district., index: 2, relevance_score: 0.98005307>, RerankResult<document['text']: Capital punishment (the death penalty) has existed in the United States since beforethe United States was a country. As of 2017, capital punishment is legal in 30 of the 50 states., index: 3, relevance_score: 0.27904198>, RerankResult<document['text']: Carson City is the capital city of the American state of Nevada., index: 0, relevance_score: 0.10194652>, RerankResult<document['text']: The Commonwealth of the Northern Mariana Islands is a group of islands in the Pacific Ocean. Its capital is Saipan., index: 1, relevance_score: 0.0721122>]

有序的数组也按照相关性的顺序排列整齐。

除此之外，似乎可以指定多语言模型（model=rerank-multilingual-v2.0），并且可以指定一个参数来指定要包含在有序数组中的响应数量（top_n=3） 。以下是我尝试过的一些示例。

示例：尝试日语 (model=rerank-multilingual-v2.0)，让我们使用将前面的文档和查询应用到 DeepL 的结果。

示例代码，

docs_ja = ['カーソンシティはアメリカ・ネバダ州の州都である','北マリアナ諸島連邦は太平洋に浮かぶ島々である。首都はサイパンである。',' ワシントンD.C.（Washington, D.C.）は、アメリカ合衆国の首都である。連邦区である','死刑制度はアメリカ合衆国が国である以前から存在する。2017年現在、死刑は50州のうち30州で合法である。'
]co_rerank_ja = co.rerank(model='rerank-multilingual-v2.0',query='アメリカの首都は何ですか？',documents=docs_ja
)print(co_rerank_ja)

输出结果，

[RerankResult<document['text']:  ワシントンD.C.（Washington, D.C.）は、アメリカ合衆国の首都である。連邦区である, index: 2, relevance_score: 0.9998813>, RerankResult<document['text']: カーソンシティはアメリカ・ネバダ州の州都である, index: 0, relevance_score: 0.37903354>, RerankResult<document['text']: 北マリアナ諸島連邦は太平洋に浮かぶ島々である。首都はサイパンである。, index: 1, relevance_score: 0.23899394>, RerankResult<document['text']: 死刑制度はアメリカ合衆国が国である以前から存在する。2017年現在、死刑は50州のうち30州で合法である。, index: 3, relevance_score: 0.0007014083>]

与默认模型一样，即使在日语中，有序数组也按照相关顺序整齐排列。

示例：仅返回日语中最高相关性 (top_n=1) (model=rerank-multilingual-v2.0)。

示例代码，

docs_ja = ['カーソンシティはアメリカ・ネバダ州の州都である','北マリアナ諸島連邦は太平洋に浮かぶ島々である。首都はサイパンである。',' ワシントンD.C.（Washington, D.C.）は、アメリカ合衆国の首都である。連邦区である','死刑制度はアメリカ合衆国が国である以前から存在する。2017年現在、死刑は50州のうち30州で合法である。'
]co_rerank_ja = co.rerank(model='rerank-multilingual-v2.0',query='アメリカの首都は何ですか？',documents=docs_ja,top_n=1,
)print(co_rerank_ja)

输出结果，

[RerankResult<document['text']:  ワシントンD.C.（Washington, D.C.）は、アメリカ合衆国の首都である。連邦区である, index: 2, relevance_score: 0.9998813>]

我还尝试了一个名为 return_documents 的参数（是否在返回的数组中包含文档），但效果不佳。
