PhiベースでファインチューニングしたLLM、Samantha-phiは、作者のエリック・ハートフォード氏によれば「スマホやスマートウォッチで動作するLLM」だそうだ。

本当か!?
ということで早速調査してみた。

 Sure, I'd be happy to help! Pancakes are a delicious breakfast choice. Here's a simple recipe for you:

**Pancake recipe**
- 1 lb pancake mix
- 1/4 cup milk
- 1/2 cup vegetable oil
- 1/4 cup water
- 1 teaspoon vanilla extract
- 1 large egg
- 1 cup shredded cheddar cheese
- 1 cup fresh fruit, like strawberries or blueberries

1. In a microwave-safe bowl, mix the pancake mix with milk, vegetable oil, water, and vanilla extract.
2. Microwave the mixture on high for 1 minute, then stir it until it's smooth.
3. Pour the batter into a greased 9x9-inch pancake pan.
4. Cook the pancakes on medium heat, flipping them over occasionally until they're golden brown on both sides.
5. Remove the pancakes from the pan, and let them cool for a minute before stacking them on a plate.
6. Serve the pancakes with milk, vegetable oil, water, and vanilla extract, along with any desired toppings.

 Python is a popular programming language, and mastering it can open many doors in the tech world. Here are some tips to help you master Python:

1. Familiarize yourself with the language: Learn the basics of Python syntax and how to use common variables, functions, and data types.

2. Practice with examples: Write simple programs and use online resources to explore Python's capabilities.

3. Join a community: Engage with fellow Python enthusiasts online or in person. This can help you learn from others' experiences and answer any questions you may have.

4. Attend workshops or courses: Investigate local workshops, online courses, or enroll in a Python course to improve your skills and gain deeper understanding of the language.

5. Experiment with libraries: Explore the various libraries and data structures in Python, as they can save time and simplify your code.

 Tokyo, a city with a rich history and vibrant culture, provides an excellent backdrop for your narrative. You might consider the city's unique blend of tradition and modernity, as well as the potential for your story to explore themes of tradition, innovation, and the harmonious coexistence of different cultures.

できそうだが、手間がかかりそう。物語作成なら他の手段(AI Bunchoなど)のほうが良さそうだ。

ただびっくりしたのはVRAMのフットプリント。

これはfp16なので、4ビット量子化すればさらに半分、2GBくらいで動くことになる。確かにスマホが射程に入ってきた感じはする(スマートウォッチは知らない)

これのもとになったPhiというやつがまたすごいのだがそれは項を改めることにしよう。

とにかく今日はたくさんニュースがあってついていくのが精一杯だ。
もうこの状況に慣れてきてしまったのだが、慣れてしまっていいのかという疑問もある。
