Learn extra bulletins about Phi-3 at Microsoft Construct 2024: New fashions added to the Phi-3 household, obtainable on Microsoft Azure.
We’re excited to introduce Phi-3, a household of open AI fashions developed by Microsoft. Phi-3 fashions are the most succesful and cost-effective small language fashions (SLMs) obtainable, outperforming fashions of the identical measurement and subsequent measurement up throughout a wide range of language, reasoning, coding, and math benchmarks. This launch expands the collection of high-quality fashions for purchasers, providing extra sensible selections as they compose and construct generative AI purposes.
Beginning immediately, Phi-3-mini, a 3.8B language mannequin is on the market on Microsoft Azure AI Studio, Hugging Face, and Ollama.
- Phi-3-mini is on the market in two context-length variants—4K and 128K tokens. It’s the first mannequin in its class to help a context window of as much as 128K tokens, with little influence on high quality.
- It’s instruction-tuned, that means that it’s skilled to observe various kinds of directions reflecting how folks usually talk. This ensures the mannequin is able to use out-of-the-box.
- It’s obtainable on Azure AI to make the most of the deploy-eval-finetune toolchain, and is on the market on Ollama for builders to run domestically on their laptops.
- It has been optimized for ONNX Runtime with help for Home windows DirectML together with cross-platform help throughout graphics processing unit (GPU), CPU, and even cell {hardware}.
- Additionally it is obtainable as an NVIDIA NIM microservice with a normal API interface that may be deployed wherever. And has been optimized for NVIDIA GPUs.
Within the coming weeks, extra fashions can be added to Phi-3 household to supply prospects much more flexibility throughout the quality-cost curve. Phi-3-small (7B) and Phi-3-medium (14B) can be obtainable within the Azure AI mannequin catalog and different mannequin gardens shortly.
Microsoft continues to supply the most effective fashions throughout the quality-cost curve and immediately’s Phi-3 launch expands the collection of fashions with state-of-the-art small fashions.

Groundbreaking efficiency at a small measurement
Phi-3 fashions considerably outperform language fashions of the identical and bigger sizes on key benchmarks (see benchmark numbers beneath, increased is best). Phi-3-mini does higher than fashions twice its measurement, and Phi-3-small and Phi-3-medium outperform a lot bigger fashions, together with GPT-3.5T.
All reported numbers are produced with the identical pipeline to make sure that the numbers are comparable. In consequence, these numbers might differ from different revealed numbers attributable to slight variations within the analysis methodology. Extra particulars on benchmarks are supplied in our technical paper.
Word: Phi-3 fashions don’t carry out as properly on factual information benchmarks (akin to TriviaQA) because the smaller mannequin measurement leads to much less capability to retain info.
Security-first mannequin design
Phi-3 fashions had been developed in accordance with the Microsoft Accountable AI Commonplace, which is a company-wide set of necessities based mostly on the next six ideas: accountability, transparency, equity, reliability and security, privateness and safety, and inclusiveness. Phi-3 fashions underwent rigorous security measurement and analysis, red-teaming, delicate use evaluation, and adherence to safety steering to assist be sure that these fashions are responsibly developed, examined, and deployed in alignment with Microsoft’s requirements and greatest practices.
Constructing on our prior work with Phi fashions (“Textbooks Are All You Want”), Phi-3 fashions are additionally skilled utilizing high-quality information. They had been additional improved with in depth security post-training, together with reinforcement studying from human suggestions (RLHF), automated testing and evaluations throughout dozens of hurt classes, and handbook red-teaming. Our strategy to security coaching and evaluations are detailed in our technical paper, and we define advisable makes use of and limitations within the mannequin playing cards. See the mannequin card assortment.
Unlocking new capabilities
Microsoft’s expertise delivery copilots and enabling prospects to remodel their companies with generative AI utilizing Azure AI has highlighted the rising want for different-size fashions throughout the quality-cost curve for various duties. Small language fashions, like Phi-3, are particularly nice for:
- Useful resource constrained environments together with on-device and offline inference situations.
- Latency sure situations the place quick response instances are essential.
- Price constrained use circumstances, notably these with less complicated duties.
For extra on small language fashions, see our Microsoft Supply Weblog.
Due to their smaller measurement, Phi-3 fashions can be utilized in compute-limited inference environments. Phi-3-mini, specifically, can be utilized on-device, particularly when additional optimized with ONNX Runtime for cross-platform availability. The smaller measurement of Phi-3 fashions additionally makes fine-tuning or customization simpler and extra reasonably priced. As well as, their decrease computational wants make them a decrease value choice with a lot better latency. The longer context window allows taking in and reasoning over massive textual content content material—paperwork, internet pages, code, and extra. Phi-3-mini demonstrates sturdy reasoning and logic capabilities, making it a very good candidate for analytical duties.
Clients are already constructing options with Phi-3. One instance the place Phi-3 is already demonstrating worth is in agriculture, the place web may not be readily accessible. Highly effective small fashions like Phi-3 together with Microsoft copilot templates can be found to farmers on the level of want and supply the extra good thing about working at diminished value, making AI applied sciences much more accessible.
ITC, a number one enterprise conglomerate based mostly in India, is leveraging Phi-3 as a part of their continued collaboration with Microsoft on the copilot for Krishi Mitra, a farmer-facing app that reaches over one million farmers.
“Our aim with the Krishi Mitra copilot is to enhance effectivity whereas sustaining the accuracy of a giant language mannequin. We’re excited to associate with Microsoft on utilizing fine-tuned variations of Phi-3 to satisfy each our targets—effectivity and accuracy!”

Originating in Microsoft Analysis, Phi fashions have been broadly used, with Phi-2 downloaded over 2 million instances. The Phi collection of fashions have achieved outstanding efficiency with strategic information curation and progressive scaling. Beginning with Phi-1, a mannequin used for Python coding, to Phi-1.5, enhancing reasoning and understanding, after which to Phi-2, a 2.7 billion-parameter mannequin outperforming these as much as 25 instances its measurement in language comprehension.1 Every iteration has leveraged high-quality coaching information and information switch strategies to problem typical scaling legal guidelines.
Get began immediately
To expertise Phi-3 for your self, begin with taking part in with the mannequin on Azure AI Playground. You can too discover the mannequin on the Hugging Chat playground. Begin constructing with and customizing Phi-3 on your situations utilizing the Azure AI Studio. Be a part of us to be taught extra about Phi-3 throughout a particular stay stream of the AI Present.
