GPT-5.5 Instant is the new default with added memory, Gmail, and Codex integration, alongside Realtime-2 and Images 2.0. Codex shows major productivity gains like reducing 180 hours to 15 hours in case studies and is considered the best coding model.
What is GPT-Rosalind and what concerns does it raise?
GPT-Rosalind is a hidden biology model from OpenAI with noted dual-use concerns. It is part of broader discussions around AI capabilities and risks in the rollout.
How is OpenAI positioning ChatGPT for the future?
OpenAI plans to evolve ChatGPT into a 'super app' ahead of going public, with 5M weekly active users and strong growth among knowledge workers. It also released a June 2026 report on malicious AI uses and added features like saving rate limit resets.
GPT-5.5 Instant default + memory/Gmail/Codex; Realtime-2; Images 2.0; Codex case study shows 180h→15h productivity gain. GPT-5.5 crowned best coding model. GPT-Rosalind hidden biology model with dual-use concerns. OpenAI launches six job-specific Codex plug-ins and Sites feature; 5M weekly active users, 20% knowledge workers growing 3x faster than devs. Codex adoption in India up 27x. Codex expanding beyond coding (farms, iOS apps, Figma). OpenAI plans to turn ChatGPT into 'super app' before going public. MIT study claims AI coding tools boost code volume 300% but output only 30%, challenging productivity narrative. FrontierCode benchmark emerges, measuring mergeability over test passing. New economic perspective: adoption friction is organizational, not model quality. Hacker News discussion echoes MIT study. OpenAI released June 2026 report on malicious uses of AI. Direct comparison shows DeepSeek V4 competitive. New: Codex now lets you save rate limit resets for later use. AI price war intensifies, piling pressure on OpenAI and Anthropic. New: Runway inside ChatGPT integration for creative workflows. New: ChatGPT market share slips below 50% for first time. New: OpenAI's pre-deployment test replays real user conversations to spot behavioral drift.
