’s Phi-3.5 artificial intelligence (AI) models. The Phi-3.5 series of small language models (SLMs), comprising Phi-3.5 Mixture of Experts (MoE), Phi-3.5 Mini, and Phi-3.5 Vision, was released in August. The open-source AI models were made available on Hugging Face. Instead of being typical conversational models, these were instruct models that require users to input specific instructions to get the desired output.

, MediaTek announced that its Dimenisty 9400, Dimensity 9300, and Dimensity 8300 chipsets are now optimised for the Phi-3.5 AI models. With this, these mobile platforms can efficiently process and run inference for on-device generative AI tasks using MediaTek’s neural processing units (NPUs).

Optimising a chipset for a specific AI model involves tailoring the hardware design, architecture, and operation of the chipset to efficiently support the processing power, memory access patterns, and data flow of that particular model. After optimising, the AI model will show reduced latency and power consumption, and increased throughput.

MediaTek highlighted that its processors are not only optimised for

’s Phi-3.5 MoE but also for Phi-3.5 Mini which offers multi-lingual support and Phi-3.5 Vision which comes with multi-frame image understanding and reasoning.

Notably, the Phi-3.5 MoE has 16×3.8 billion parameters. However, only 6.6 billion of them are active parameters when using two experts (typical use case). On the other hand, Phi-3.5 features 4.2 billion parameters and an image encoder, and the Phi-3.5 Mini has 3.8 billion parameters.

claimed that the Phi-3.5 MoE outperformed both Gemini 1.5 Flash and GPT-4o mini AI models on the SQuALITY benchmark which tests readability and accuracy when summarising a block of text.

Phi-3.5 directly via Hugging Face or the Azure AI Model Catalogue, MediaTek’s NeuroPilot SDK toolkit also offers access to these SLMs. The chip maker stated that the latter will enable developers to build optimised on-device applications capable of generative AI inference using the AI models across the above mentioned mobile platforms.
