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.

About the book "Piranesi"

Cover of the book "Piranesi"

"Piranesi" is both a continuation of the magical stories of Susanna Clarke and an independent book.

The book has no direct connection with the world of English magic [ru] from "Jonathan Strange & Mr. Norrell". If desired, one can find a connection and even say that the worlds are the same, only at different times: the events of "Piranesi" take place in the early 2000s. However, the author did not give any hints on this. Therefore, I consider the worlds to be different for now.

Susanna continues to persistently and effectively dig not even in the direction of animism as the basis of world perception but in the direction of extremely holistic view of the world, in contrast to the currently dominant reductionism.

The latter blows my mind. As an engineer, I'm an intuitive reductionist due to professional deformation. Reading "Jonathan Strange" and "Piranesi", I felt how Clarke, like Peter the Great, cuts a window in my brain to another picture of the world, a different world perception. And it's wonderful.

By the way, don't confuse holism with, say, an engineering view of the world, a-la systems engineering [ru] or even science. The latter is about decomposing reality into isolated parts with clear boundaries and synthesizing "pure" models of the world [ru], while in holism, the parts have no clear boundaries and penetrate each other.

But it is my interpretation, there are interpretations when holism is just an alternative name for a systems thinking/view — it's hard to find literature on this topic now, so it's hard for me to say where the truth is.

So, "Piranesi"

About the book "Economics: The User's Guide"

Cover of the book "Economics: The User's Guide"

This is the second book by Ha-Joon Chang that I've read. The first one, Bad Samaritans [ru], left a good impression, and it was also positively reviewed by Tim O'Reilly in his book WTF? [ru]. So, "Economics: The User's Guide" took its place on my reading list, and finally, I have read it.

Here and further, all quotes point to the Russian edition of the book and are translated into English by me (I have only the Russian edition) => inconsistencies are possible because of double translation English->Russian->English.

According to Chang, the book was conceived as an "introduction to economic theory for the widest possible audience" (page 299), and this reflects its essence well. I would only add, from the perspective of my post-Soviet education, that the book looks more like an "overview of the diversity and complexity of economics, supplemented with an introduction to the theory" rather than an "introduction to the theory".

The book contains no mathematical formulas or jaw-dropping statistics, just concrete facts. What makes it valuable, however, is a set of prisms through which you can — and should — view the economy to gain a basic understanding of what's happening around you.

Chan provides a set of points of view through which you can examine economic processes; describes their advantages and disadvantages; accompanies all this with examples, historical references, and facts.

Since the book serves as a sort of textbook, I won't attempt to retell it in full — this would lead to an attempt to repeat the book in a couple of pages, and I definitely can't do that. I will limit myself to describing the author's view of the economy as a whole as I understood it.

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.
