OpenAI Loosens ChatGPT Access While Perplexity Eyes Ads, Both Tread Carefully to Avoid Bias
• OpenAI tweaks ChatGPT to allow instant access without an account, but adds "safeguards" and says logged-in users get more features
• Perplexity AI exploring adding ads to platform to generate revenue, but says it won't let ads bias answers
• Perplexity won't show ads before answers, is looking at "related questions" as entry point for brands
• OpenAI says user prompts may still train models even without accounts, but this can be disabled
• Perplexity distinguishes itself as an "answer engine" that provides citations, not just a chatbot
