ChatGPT's o3 is OpenAI's best model to date because it features reasoning, and it might get even better in the next update. As spotted on X, OpenAI is testing a new "Alpha" variant of the o3 model, which has significant coding-related improvements. In our tests, BleepingComputer observed that o3-alpha is better than o3 in designing web pages, even with simple prompts.

Mistral AI, the French company behind AI assistant Le Chat and several foundational models, is officially regarded as one of France’s most promising tech startups and is arguably the only European company that could compete with OpenAI. But compared to its $6 billion valuation, its global market share is still relatively low.

How to Get Foreign Keys Horribly Wrong

news.ycombinator.com Haki Benita 2025-07-16 22:36:08

Constraints keep the integrity of your system and prevent you from shooting yourself in the foot. Foreign keys are a special type of constraint because, unlike unique, check, and primary keys, they span more than one relation. This makes foreign keys harder to enforce and harder to get right. In this article, I demonstrate common pitfalls, potential optimizations, and implicit behavior related to foreign keys.

In the early days of large language models, there was a high barrier to entry: it used to be impossible to run anything useful on your own computer without investing in pricey GPUs.
