我們的模型並非專門為所有下游目的而設計或評估。開發人員在選擇用例時應考慮語言模型的常見限制，並在特定下游用例中使用之前，評估並減輕準確性、安全性與公平性，特別是對於高風險情境。開發人員應注意並遵守適用於其用例的相關法律或法規（包括隱私、貿易合規法律等）。本模型卡中包含的任何內容均不應被解釋或視為對模型發布所依據的許可證的限制或修改。

負責任的 AI 考量

與其他語言模型一樣，Phi 系列模型可能以不公平、不可靠或冒犯性的方式運作。需要注意的限制行為包括

服務品質：Phi 模型主要以英文文本進行訓練。非英語語言將體驗較差的性能。英語變體表示較少的情況可能比標準美式英語體驗更差的性能。
危害的呈現與刻板印象的延續：這些模型可能過度或不足地呈現人群群體，抹去某些群體的呈現，或強化貶低或負面的刻板印象。儘管進行了安全性後訓練，但由於不同群體的呈現程度不同，或訓練數據中負面刻板印象示例的普遍性反映了真實世界的模式和社會偏見，因此這些限制可能仍然存在。
不當或冒犯性內容：這些模型可能會產生其他類型的不當或冒犯性內容，這可能使其不適合在敏感情境中部署，除非有特定於用例的額外緩解措施。
資訊可靠性：語言模型可能會產生無意義的內容或捏造聽起來合理但不準確或過時的內容。
程式碼的有限範圍：Phi-3 的大部分訓練數據都基於 Python，並使用「typing, math, random, collections, datetime, itertools」等常用套件。如果模型產生使用其他套件的 Python 腳本或以其他語言編寫的腳本，我們強烈建議使用者手動驗證所有 API 使用。

開發人員應應用負責任的 AI 最佳實踐，並負責確保特定用例符合相關法律法規（例如隱私、貿易等）。重要的考量領域包括：+ 分配：在沒有進一步評估和額外的去偏見技術的情況下，模型可能不適用於可能對法律地位或資源或生活機會分配產生重大影響的情境（例如：住房、就業、信貸等）。

高風險情境：開發人員應評估在高風險情境中使用模型的適用性，在這些情境中，不公平、不可靠或冒犯性的輸出可能極其昂貴或導致傷害。這包括在準確性和可靠性至關重要的敏感或專業領域（例如：法律或健康建議）中提供建議。應根據部署情境在應用層級實施額外的安全措施。
錯誤資訊：模型可能會產生不準確的資訊。開發人員應遵循透明度最佳實踐，並通知最終使用者他們正在與 AI 系統互動。在應用層級，開發人員可以建立回饋機制和管道，以在特定用例的上下文資訊中建立回應基礎，這是一種稱為檢索增強生成 (RAG) 的技術。
有害內容的產生：開發人員應評估輸出的上下文，並使用適用於其用例的可用安全分類器或自訂解決方案。
誤用：其他形式的誤用（例如詐欺、垃圾郵件或惡意軟體生產）可能發生，開發人員應確保其應用程式不違反適用法律法規。

## 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.
