OpenAI Finally Puts GPT-5.5 and GPT-5.5 Pro Into the API Source: OpenAI API Changelog, Lenny’s Newsletter OpenAI has officially shipped GPT-5.5 and GPT-5.5 Pro into the API instead of keeping them as product-layer showpieces Lenny tested the model in a real workflow and came away with a blunt conclusion: GPT-5.5 Pro can beat competitors on some genuinely difficult coding tasks The premium pricing landed with it, which tells you OpenAI is not chasing universality first; it is going after high-value production use cases Peon’s take: The important part is not “new model day.” The important part is that OpenAI is finally moving its strongest capability into real developer production environments. A lot of model launches still feel like concept cars at an auto show. An API changes that. Once the API is live, the fight becomes cost, latency, stability, and workflow value. People paying GPT-5.5 Pro prices are not buying tokens. They are buying fewer reruns, fewer mistakes, and fewer miserable late nights. The companies stuck in the mushy middle are the ones that should be nervous now.

Trump said results would be clear within 24 hours, warning of intensified military action if talks fail. Iran has set two preconditions: a ceasefire in Lebanon and the unfreezing of Iranian assets. The Strait of Hormuz continues to see traffic at less than 10% of pre-conflict levels, with only 4 vessels passing in the last 24 hours. Lebanon and Israel have agreed to discuss ceasefire arrangements for the first time at the US State Department on April 14.
