OpenAI unveils GPT-5.2 for professionals
OpenAI has released GPT-5.2, its most advanced Frontier model for professional use, available in Instant, Thinking, and Pro variants. Rollout starts today in ChatGPT and via the API, initially for paying users, as announced by Nick Turley, Head of ChatGPT. The model targets tasks such as building spreadsheets, creating presentations, coding, and complex reasoning, with Thinking highlighted for professionals and GDPval benchmarking. GPT-5.2 includes improved reasoning and safety features to better recognize emotional load. OpenAI notes expert-level performance on GDPval across 44 tasks. Concurrently, Anthropic announced Claude Code 2.0.65 with updates including Cloud Tasks, a simpler cross-model switch via Alt/Option keys, and a configurable status line to track context. The piece also positions GPT-5.2 within a broader competitive AI landscape.
OpenAI launches GPT-5.5
Claire Vo publishes hands-on testing of OpenAI’s newly released GPT-5.5 and GPT-5.5 Pro (rolled into Codex and ChatGPT). Vo reports the models show higher capacity for complex work and greater token efficiency, and she demonstrates developer-focused use cases: long-running autonomous agent loops in Codex (including a near-six-hour run that reportedly handled 98% of migration edge cases and reduced Sentry errors), tackling tech-debt in a ChatPRD codebase, and reverse-engineering a proprietary Divoom MiniToo Bluetooth pixel speaker after other models failed. The article notes pricing the author calls expensive (reports GPT-5.5 at $5 per million input tokens and $30 per million output tokens; GPT-5.5 Pro referenced with '34 million input tokens' and $180 for output tokens) and highlights Codex features like a /personality command for tone customization. The piece complements OpenAI’s April 23, 2026 GPT-5.5 launch with practical developer workflows and measurements.
OpenAI launches ChatGPT Work powered by GPT-5.6
OpenAI announced ChatGPT Work, an agentic workflow capability inside ChatGPT that can gather context across connected apps, break multi-step projects into sub-tasks, and create finished materials like slides, sheets, docs and web apps.
