Microsoft has unveiled its latest light AI model called the Phi-3 Mini designed to run on smartphones and other local devices, it revealed in a new research paper. Trained on 3.8 billion parameters, it's the first of three small Phi-3 language models the company will release in the near future. The aim is to provide a cheaper alternative to cloud-powered LLMs, allowing smaller organizations to adopt AI. 

According to Microsoft, the new model handily outperforms its previous Phi-2 small model and is on par with larger models like Llama 2. In fact, the company says Phi-3 Mini provides responses close to the level of a model 10 times its size. 

"The innovation lies entirely in our dataset for training," according to the research paper. That dataset is based on the Phi-2 model, but uses "heavily filtered web data and synthetic data," the team states. In fact, a separate LLM was used to do both of those chores, effectively creating new data that allows the smaller language model to be more efficient. The team was supposedly inspired by children's books that use simpler language to get across complex topics, according to The Verge.

While it still can't produce the results of cloud-powered LLMs, Phi-3 Mini can outperform Phi-2 and other small language models (Mistral, Gemma, Llama-3-In) in tasks ranging from math to programming to academic tests. At the same time, it runs on devices as simple as smartphones, with no internet connection required.

Its main limitation is breadth of "factual knowledge" due to the smaller dataset size — hence why it doesn't perform well in the "TriviaQA" test. Still, it should be good for models that only require smallish internal data sets. That could allow companies that can't afford cloud-connected LLMs to jump into AI, Microsoft hopes.

Phi-3 Mini is now available on Azure, Hugging Face and Ollama. Microsoft is next set to release Phi-3 Small and Phi-3 Medium with significantly higher capabilities (7 billion and 14 billion parameters, respectively). 

DJI is entering the portable power station market in the US and Europe with the launch of the Power 1000 and Power 500 aimed at home users or road warriors. The devices (released in China at the end of last year) can be used to power small appliances or charge devices like laptops or drones, and work in concert with solar panels to provide power on the road. 

The Power 1000 (13kg or 29 pounds) has a 1,024 Wh capacity and can output up to 2,200W — enough to run a home microwave oven for about 1.3 hours and a car refrigerator for 19 hours, or charge a drone up to 12 times. The Power 500 (7.3 kg or 16.3 pounds) delivers 512 Wh of capacity and 1,000W of output for half the price.

The larger version supports 1200W fast recharge or 600W standard recharging (540W and 270W for the smaller version). Both can be fast-charged in 70 minutes for a 100 percent battery or 50 minutes to an 80 percent charge. Along with standard AC plugs, both have a pair of USB-C PD output ports that support 140W/100W charging for the Power 1000/Power 500 — enough for most laptops.

The market is fairly saturated with such devices (Jackery, Bluetti, Anker, others), but DJI is pitching this as an ideal way to charge its drones and other products. Released in China in December, it was already available in the US at Amazon and elsewhere via the grey market. 

The Power 1000 is now on sale for $1,000 at DJI's store, while the Power 500 costs $500. You can add a 120W Zignes solar panel for $299. For the latter, you'll need DJI's Power Solar Panel Adapter Module or DJI Power Car Power Outlet to SDC Power Cable.
