GitHub Copilot Costs

In my last post I spoke about how I’ve been gradually adopting AI-assisted coding. I didn’t think much about costs because the tool has been improving over time and it’s come to a point where I acknowledge I rely on assistants, and by doing manual coding my productivity would take a major hit. For now I feel every euro spent has been worth it, so I mostly ignore the money side. However, how can you not notice the humongous investments being made in datacenters, the crazy valuations of companies yet to turn a profit, and the worrying news of layoffs by the big American companies? That makes you think about how this frenzy is justified from a financial standpoint; the LLMs themselves are a marvel. How are those companies going to make all that money back? Sure, although I’m a developer, I’m a European in a low-income country. I’ll surely pay some euros each month on tools, but I don’t see coders around here spending in ways that would make the financial side add up. Maybe in the US things are different and devs are spending like $1000/month on AI tools, but I don’t plan to increase my spending much and I don’t think my employer is either. Furthermore, from the laypeople side, I don’t know a single person paying for an AI assistant. But honestly, in Spain we’re very frugal; the free versions should be barely functional before anyone decides to spend even €10 on software. ...

My experience using LLMs as a software developer

My AI assisted coding history It seems ages have passed by, but it was only 2020 when ChatGPT-3 was released. We developers and technology enthusiasts had been aware of it, but in November 2022 ChatGPT-3.5 was released to the mass market and rocked the world. This is the timeline: Year Model Impact 2018 GPT-1 Research prototype. 2019 GPT-2 Significant attention in the AI community, but not widely used by the public. 2020 GPT-3 Impressive capabilities, mostly accessed through APIs and developer tools. Nov 2022 ChatGPT (GPT-3.5) First version to become a global phenomenon. Mar 2023 GPT-4 Major quality improvement, building on ChatGPT’s already massive user base. At first I used it like many other developers, I assume. Just copy and paste from the browser or ChatGPT app to the IDE. This was fine for scripts or very localized problems, and that small assistance to my daily coding was enough for a couple of years, until I subscribed to GitHub Copilot in August 2025. ...
