GPT 5.5 Unlocked: New Possibilities

This episode of Machine Learning Street Talk dives into a flurry of major AI developments across OpenAI, Apple, and Google. OpenAI has launched GPT 5.5 Instant as the new default model, touting a 52.5% reduction in hallucinations—especially in high-stakes domains like medicine, law, and finance—along with improved benchmark scores and a new memory sources panel for transparency. The company also rolled out a self-serve ads manager for US advertisers, aiming for $2.5 billion in ad revenue this year and $100 billion by 2030, signaling aggressive monetization ambitions. Greg Brockman confirmed under oath that OpenAI will spend $50 billion on compute in 2026, underscoring the massive infrastructure demands fueling AI progress. Meanwhile, Apple is finally opening Siri to third-party models like Gemini, Claude, and ChatGPT via extensions in iOS 27, iPadOS 27, and macOS 27, set to launch at WWDC on June 8th—though this comes amid a $250 million fine for falsely advertising Apple Intelligence's availability. On the privacy front, a researcher exposed Chrome silently downloading a 4GB Gemini Nano model without consent, raising GDPR and e-privacy concerns. The episode concludes with a plug for AIbox.ai, a platform offering access to 80+ AI models for $8.99/month, promising cost savings for users juggling multiple AI subscriptions.
