One of the quickest ways to call multiple AI models from a single Python script is to use OpenRouter’s API, which acts as a unified routing layer between your code and multiple AI providers. By the end of this course, you’ll be able to access models from several providers through one unified API. This convenience matters because the AI ecosystem is highly fragmented: each provider exposes its own API, authentication scheme, rate limits, and model lineup. Working with multiple providers […]

While the Northern Hemisphere warms up for summer, Python 3.15 went the other way with its beta 1 feature freeze 🥶. Since May 7, the list of what will be included in the next release is final. That list includes a brand-new sentinel built-in that finally standardizes a pattern Python developers have been hand-rolling for decades. And while AI kept writing code, buggy or not, developers also directed it to look for bugs in code that had been sitting untouched […]
