Where the goblins came from

656 ilreb 2026-04-30 03:41:15 UTC openai.com Llama Share 354

OpenAI's models started mentioning creatures like goblins and gremlins in their metaphors due to a subtle incentive from training for the personality customization feature, specifically the Nerdy personality. The behavior was amplified through transfer from Nerdy personality training and later spread to other contexts, requiring OpenAI to retire the Nerdy personality and implement new tools ...

SemiAnalysis conducted a five-month analysis of the MI300X GPU, comparing its performance to Nvidia's H100 and H200, and found that AMD's software issues hold back the MI300X's potential. The MI300X has a lower total cost of ownership but weaker training performance compared to Nvidia's GPUs, and AMD needs to improve its software stack and testing to be competitive.

FastCGI: 30 years old and still the better protocol for reverse proxies

Using FastCGI as a protocol for proxy-to-backend communication can avoid HTTP's pitfalls, such as desync vulnerabilities, by providing clear message boundaries and domain separation between client and proxy headers. FastCGI is a 30-year-old protocol that is still usable today, but its lack of awareness and outdated tooling may hinder its adoption despite its potential benefits.
