我们的模型并非专门设计或评估用于所有下游用途。开发人员在选择用例时应考虑语言模型的常见局限性，并在用于特定下游用例之前评估和降低准确性、安全性和公平性方面的风险，尤其是在高风险场景中。开发人员应了解并遵守与其用例相关的适用法律法规（包括隐私、贸易合规法律等）。模型卡片中包含的任何内容均不应被解释为或被视为对模型发布许可的限制或修改。

负责任的 AI 考虑

与其他语言模型一样，Phi 系列模型可能会以不公平、不可靠或具有冒犯性的方式运行。需要注意的一些限制性行为包括

服务质量：Phi 模型主要基于英文文本进行训练。非英语语言的性能会较差。训练数据中代表性较低的英语变体可能比标准美式英语的性能更差。
有害表征与刻板印象的延续：这些模型可能会过度或不足地代表人群，抹去某些群体的代表性，或强化贬低或负面的刻板印象。尽管进行了安全后期训练，但由于不同群体的代表性程度不同或训练数据中负面刻板印象的例子普遍存在（反映了现实世界中的模式和社会偏见），这些限制仍然可能存在。
不当或冒犯性内容：这些模型可能会产生其他类型的不当或冒犯性内容，这可能使其不适合在敏感环境中部署，除非采取针对特定用例的其他缓解措施。
信息可靠性：语言模型可能会生成无意义的内容或捏造听起来合理但实际上不准确或过时内容。
代码范围有限：Phi-3 的大部分训练数据都基于 Python，并使用常见的包，例如“typing、math、random、collections、datetime、itertools”。如果模型生成的 Python 脚本使用了其他包或其他语言的脚本，我们强烈建议用户手动验证所有 API 的使用。

开发人员应应用负责任的 AI 最佳实践，并有责任确保特定用例符合相关的法律法规（例如隐私、贸易等）。需要考虑的重要方面包括：+ 分配：如果没有进一步的评估和额外的去偏见技术，模型可能不适合可能对法律地位或资源或生活机会的分配产生重大影响的场景（例如：住房、就业、信贷等）。

高风险场景：开发人员应评估在高风险场景中使用模型的适用性，在这些场景中，不公平、不可靠或具有冒犯性的输出可能会造成极高的代价或导致损害。这包括在准确性和可靠性至关重要的敏感或专业领域提供建议（例如：法律或健康建议）。应根据部署环境在应用程序级别实施额外的安全措施。
错误信息：模型可能会产生不准确的信息。开发人员应遵循透明度最佳实践，并告知最终用户他们正在与 AI 系统交互。在应用程序级别，开发人员可以构建反馈机制和管道，以便将响应基于特定用例的上下文信息中，这是一种称为检索增强生成 (RAG) 的技术。
有害内容的生成：开发人员应根据其上下文评估输出，并使用可用的安全分类器或适合其用例的自定义解决方案。
滥用：其他形式的滥用，例如欺诈、垃圾邮件或恶意软件生产，也是可能的，开发人员应确保其应用程序不违反适用的法律法规。

## Phi-3 Mini

Phi-3 Mini is a 3.8B parameters, lightweight, state-of-the-art open model trained with the Phi-3 datasets that includes both synthetic data and the filtered publicly available websites data with a focus on high-quality and reasoning dense properties.

The model has underwent a post-training process that incorporates both supervised fine-tuning and direct preference optimization to ensure precise instruction adherence and robust safety measures.

When assessed against benchmarks testing common sense, language understanding, math, code, long context and logical reasoning, Phi-3 Mini-4K-Instruct showcased a robust and state-of-the-art performance among models with less than 13 billion parameters.

## Phi-3 Medium

Phi-3 Medium is a 14B parameter language model, and outperforms Gemini 1.0 Pro.

## Intended Uses

**Primary use cases**

The model is intended for commercial and research use in English. The model provides uses for applications which require
1) memory/compute constrained environments
2) latency bound scenarios
3) strong reasoning (especially math and logic)
4) long context

Our model is designed to accelerate research on language and multimodal models, for use as a building block for generative AI powered features.

**Use case considerations**

Our models are not specifically designed or evaluated for all downstream purposes. Developers should consider common limitations of language models as they select use cases, and evaluate and mitigate for accuracy, safety, and fariness before using within a specific downstream use case, particularly for high risk scenarios.
Developers  should be aware of and adhere to applicable laws or regulations (including privacy, trade compliance laws, etc.) that are relevant to their use case.
Nothing contained in this Model Card should be interpreted as or deemed a restriction or modification to the license the model is released under.

## Responsible AI Considerations
Like other language models, the Phi series models can potentially behave in ways that are unfair, unreliable, or offensive. Some of the limiting behaviors to be aware of include:

+ Quality of Service: the Phi models are trained primarily on English text. Languages other than English will experience worse performance. English language varieties with less representation in the training data might experience worse performance than standard American English.

+ Representation of Harms & Perpetuation of Stereotypes: These models can over- or under-represent groups of people, erase representation of some groups, or reinforce demeaning or negative stereotypes. Despite safety post-training, these limitations may still be present due to differing levels of representation of different groups or prevalence of examples of negative stereotypes in training data that reflect real-world patterns and societal biases.

+ Inappropriate or Offensive Content: these models may produce other types of inappropriate or offensive content, which may make it inappropriate to deploy for sensitive contexts without additional mitigations that are specific to the use case.

+ Information Reliability: Language models can generate nonsensical content or fabricate content that might sound reasonable but is inaccurate or outdated.
+ Limited Scope for Code: Majority of Phi-3 training data is based in Python and use common packages such as "typing, math, random, collections, datetime, itertools". If the model generates Python scripts that utilize other packages or scripts in other languages, we strongly recommend users manually verify all API uses.

Developers should apply responsible AI best practices and are responsible for ensuring that a specific use case complies with relevant laws and regulations (e.g. privacy, trade, etc.). Important areas for consideration include:
+ Allocation: Models may not be suitable for scenarios that could have consequential impact on legal status or the allocation of resources or life opportunities (ex: housing, employment, credit, etc.) without further assessments and additional debiasing techniques.

+ High-Risk Scenarios: Developers should assess suitability of using models in high-risk scenarios where unfair, unreliable or offensive outputs might be extremely costly or lead to harm. This includes providing advice in sensitive or expert domains where accuracy and reliability are critical (ex: legal or health advice). Additional safeguards should be implemented at the application level according to the deployment context.

+ Misinformation: Models may produce inaccurate information. Developers should follow transparency best practices and inform end-users they are interacting with an AI system. At the application level, developers can build feedback mechanisms and pipelines to ground responses in use-case specific, contextual information, a technique known as Retrieval Augmented Generation (RAG).

+ Generation of Harmful Content: Developers should assess outputs for their context and use available safety classifiers or custom solutions appropriate for their use case.

+ Misuse: Other forms of misuse such as fraud, spam, or malware production may be possible, and developers should ensure that their applications do not violate applicable laws and regulations.
