icrosoft has finally announced its latest addition to the Phi family for generative AI. Their newest addition to the generative AI models is called Phi-4 and
it's an improved model in more problem-solving situations compared to its predecessor.
Microsoft's latest model, Phi-4, is available in limited access as of Thursday night. Yet, it is only available on the Microsoft Azure AI Foundry development platform, for research purposes, and under the Microsoft research license agreement.
Even more so, Phi-4 is Microsoft’s latest small language model that comes in at 14 billion parameters in size. The model also competes with models such as GPT-4o mini or Gemini 2.0 Flash and even Claude 3.5 Haiku.
The AI model is most often faster and cheaper to use, however, the capability to perform from small language models has gotten better and better over the passing of time.
“Azure AI Foundry provides users with a robust set of capabilities to help organizations measure, mitigate, and manage AI risks across the AI development lifecycle for traditional machine learning and generative AI applications. Azure AI evaluations in AI Foundry enable developers to iteratively assess the quality and safety of models and applications using built-in and custom metrics to inform mitigations.”, This was mentioned on their website on the launch announcement.

Also mentioned “Additionally, Phi users can use Azure AI Content Safety features such as prompt shields, protected material detection, and groundedness detection. These capabilities can be leveraged as content filters with any language model included in our model catalog and developers can integrate these capabilities into their application easily through a single API.”
Microsoft attributes from Phi-4 advancement in its performance for the use of “high-quality synthetic datasets” among other high-quality datasets from human-generated content and even some post-training improvements that are not mentioned.
AI labels are even looking into innovations that they can create around synthetic data that are used post-training. It is also worth mentioning that Phi-4 is the first of the Phi-series models that was launched after the departure of Sebastien Bubeck.
