OpenAI wants to stop ChatGPT from validating users’ political views

The timing of OpenAI’s paper may not be coincidental. In July, the Trump administration signed an executive order barring “woke” AI from federal contracts, demanding that government-procured AI systems demonstrate “ideological neutrality” and “truth seeking.” With the federal government as tech’s biggest buyer, AI companies now face pressure to prove their models are politically “neutral.”… Read More: OpenAI wants to stop ChatGPT from validating users’ political views »

And AI models are… Read More: When “no” means “yes”: Why AI chatbots can’t process Persian… »
