OpenAI adds GPT-4.1 to ChatGPT amid complaints over confusing model lineup

The release comes just two weeks after OpenAI made GPT-4 unavailable in ChatGPT on April 30. That earlier model, which launched in March 2023, once sparked widespread hype about AI capabilities.

Ars Live: Our first encounter with manipulative AI

While Bing Chat’s unhinged nature was caused in part by how Microsoft defined the “personality” of Sydney in the system prompt (and unintended side-effects of its architecture with regard to conversation length), Ars Technica’s saga with the chatbot began when someone discovered how to reveal Sydney’s instructions via prompt injection, which Ars Technica then published.… Read More »
