Grainau: hiking and beer at 3000 meters

How it all looks from the ground.

How it all looks from the ground.

For her vacation, Yuliya decided to show me the beautiful German mountains and took me for a couple of days to Grainau — it's a piece of Bavaria that's almost like Switzerland. At least, it is similar to the pictures of Switzerland that I've seen :-D

In short, it's a lovely place with a measured pace of life. If you need to catch your breath, calm your nerves, and enjoy nature, then this is the place for you. But if you can't live without parties, you'll get bored quickly.

What's there:

  • The highest mountain in Germany plus a couple of glaciers.
  • There's skiing in winter. If you really need it, you can find a place to ski in summer, but the descent is short, and the lifts are turned off.
  • A large clean lake and a couple of smaller ones.
  • A huge number of trails for hiking.
  • A huge number of waterfalls, streams, and a couple of mountain rivers.
  • Restaurants with beer.
  • Beautiful fallen trees in the forests, private property, fences, cows with bells, and "racing tractors" (I don't know how to name this phenomenon better, but tractors are moving fast there :-D).

This is briefly, and now in detail.

Migrating from GPT-3.5-turbo to GPT-4o-mini

Guess when I switched models.

Guess when I switched models.

Recently OpenAI released GPT-4o-mini — a new flagship model for the cheap segment, as it were.

  • They say it works "almost like" GPT-4o, sometimes even better than GPT-4.
  • It is almost three times cheaper than GPT-3.5-turbo.
  • Context size 128k tokens, against 16k for GPT-3.5-turbo.

Of course, I immediately started migrating my news reader to this model.

In short, it's a cool replacement for GPT-3.5-turbo. I immediately replaced two LLM agents with one without changing prompts, reducing costs by a factor of 5 without losing quality.

However, then I started tuning the prompt to make it even cooler and began to encounter nuances. Let me tell you about them.

Procedural news headlines without complex text generation

A screenshot of the interface for selecting a news connotation (from the prototype of the game about a news agency). News: the arrest of a teenage witch for drunk driving.

A screenshot of the interface for selecting a news connotation (from the prototype of the game about a news agency). News: the arrest of a teenage witch for drunk driving.

From the player preference survey, I gradually moved on to working on a game prototype.

The game will be about a news agency. You will be the chief editor, and your task is to manipulate public opinion by investigating events and choosing a connotation of news: where to draw the public's attention, what to hide, in what tone to present themes, etc.

Therefore, the whole game will be around the text of news.

Creating large blocks of detailed text for each news item looks pointless — the game is not about reading news but about managing them. Therefore, it makes sense to build interaction only around headlines.

But how can we make the displaying of news both interesting and simple?

Hello, World!

Nice to meet you, friends!

My name is Aliaksei, but feel free to call me Tiendil — it is my nickname for the last 20 years or so :-)

A few words about me:

  • By occupation, I am a software developer, mostly backend, mainly in Python.
  • For most of my career, I've been working in game development on big projects and own indie games.
  • I like playing games, reading books, and writing long-reads about partially complex topics.

This is my first blog post in English, but not the first one in general. I have blogged in Russian for a long time and have always wanted to share my thoughts with the English-speaking world. At last, I found some time to adapt my blog, and here we are!

Most of the future posts will be bilingual (English & Russian). Also, with time, I'll translate my most interesting old posts.

Once again, nice to meet you! Feel free to contact me by any means.
