In direct testing, Google's Gemini successfully analyzed video content from YouTube links and local files up to 1.65GB, accurately understanding context without audio or metadata. Anthropic's Claude cannot process video at all, while OpenAI's ChatGPT faces a 500MB file size limit without Codex assistance.

OpenAI discovered its GPT-5.1 through GPT-5.4 models developed an increasing fixation on goblins, gremlins, and other mythical creatures. The issue traced back to reinforcement learning rewards used to develop a discontinued 'Nerdy personality' feature, which persisted across model generations.

OpenAI is replacing Custom GPTs with workspace agents, Codex-powered tools designed for team collaboration that can handle complex tasks and long-running workflows. The feature launches today as a research preview for ChatGPT Business, Enterprise, Edu, and Teachers plans.

OpenAI has released ChatGPT Images 2, an upgraded image generation model that produces images up to 2K resolution in multiple aspect ratios. The model ships with two versions—Instant and Thinking—and can research current web information before generating images.

OpenAI announced major updates to Codex, its automated coding tool, adding background desktop control that lets it operate apps and click through interfaces while users continue working. The update includes 111 plugin integrations and matches capabilities Anthropic released for Claude Code last month.

OpenAI has introduced a $100 per month ChatGPT Pro plan positioned between its $20 Plus and $200 Pro tiers. The new tier offers 5x more Codex capacity than Plus and access to the same advanced tools as the $200 plan, with a limited-time promotional doubling of Codex allocation.

OpenAI has introduced a new $100 per month ChatGPT Pro subscription tier offering 5x more usage of its Codex coding tool than the $20 Plus plan. The tier directly competes with Anthropic's Claude Max subscription at the same price point and sits between the $20 Plus and $200 Pro tiers.

OpenAI announced a new $100/month Pro plan for ChatGPT, filling the pricing gap between its $20/month Plus tier and $200/month option.

OpenAI announced a $100 per month ChatGPT Pro subscription tier offering five times more Codex usage than its existing $20 Plus plan. The move directly challenges Anthropic's Claude Code, which generated over $2.5 billion in run-rate revenue in February with 100%+ growth since the start of 2026. Codex now has three million weekly active users.

OpenAI has introduced a new $100/month ChatGPT Pro tier positioned for Codex users, cutting the previous $200/month Pro price in half. The new plan offers 5x higher usage limits than ChatGPT Plus (10x Codex-specific usage through May 31) while maintaining the same core capabilities as the $200 tier, which remains available for power users.

OpenAI is restructuring its subscription tiers, introducing a new $100-per-month Pro plan for heavy Codex users—half the price of its previous $200 Pro tier. The new plan includes 5x more Codex usage than the $20 Plus plan and targets users requiring extended programming sessions. This pricing move undercuts comparable offerings from Anthropic and Google.

OpenAI is replacing per-seat licensing with usage-based pricing for Codex in ChatGPT Business and Enterprise plans, eliminating upfront license costs. Eligible Business customers can claim up to $500 in promotional credit per workspace. The shift targets enterprises where coding tools typically expand from individual developers to full teams, positioning OpenAI against GitHub Copilot and Cursor.

OpenAI released a plugin that embeds its Codex coding assistant directly into Anthropic's Claude Code, the market-dominant code IDE. The plugin offers standard code review, adversarial review, and background task handoff capabilities, requiring only a ChatGPT subscription or OpenAI API key.

OpenAI is introducing plugins for Codex that bundle skills, integrations, and connectors into shareable workflow packages. The move directly addresses Claude Code's lead among developers and positions Codex beyond coding into broader agentic work platforms. Over 20 plugins are currently available, including integrations with Figma, Notion, Gmail, Slack, and Google Drive.

OpenAI has acquired Astral, the company behind widely-used Python development tools Ruff, uv, and ty, which see hundreds of millions of downloads monthly. The tools will integrate with OpenAI's Codex platform to enable agentic AI systems that can plan changes, modify codebases, run tools, and verify results. OpenAI commits to keeping the tools open source under permissive licenses post-acquisition.

OpenAI is consolidating its fragmented macOS app ecosystem by merging ChatGPT, Codex coding platform, and Atlas browser into a single "superapp" led by Chief of Applications Fidji Simo. The unified app will feature agentic AI capabilities for autonomous task execution and team collaboration, with rollout expected over coming months starting with Codex enhancements.

OpenAI is developing a unified desktop application that combines ChatGPT, its browser, and Codex code generator into a single product. The move is intended to streamline user experience and focus resources on one integrated platform, with emphasis on agentic AI capabilities that can autonomously handle tasks like software development and data analysis.

OpenAI is building a unified desktop application that combines ChatGPT, its Codex AI coding tool, and the Atlas AI-powered browser. The consolidation aims to reduce product fragmentation that OpenAI leadership says has slowed development and quality standards.

OpenAI Codex subagents reached general availability after weeks of preview, enabling developers to define custom agents as TOML files and parallelize task execution. The feature mirrors Claude Code's implementation with default subagents for exploration, worker, and default operations.

OpenAI has released its Codex AI coding tool on Windows following rapid adoption on macOS. The app achieved over 1 million downloads in its first week on Mac and now serves 1.6 million weekly active users across platforms.
