OpenAI has implemented a new "skills" feature in ChatGPT and Codex CLI, allowing users to access and utilize structured resources for tasks like document creation. The skills function by organizing Markdown files and additional resources in a specific folder, enabling tasks such as generating PDFs and creating plugins. This development mirrors similar features from Anthropic, indicating a growing trend in AI tool capabilities.

OpenAI has updated ChatGPT's Deep Research to allow for more interactive and guided sessions. Users can now focus research on specific websites, integrate context from apps, and modify the process mid-way, making it more suited for tasks that require precise sourcing and iterative exploration. There's also a potential new "Skills" layer on the horizon to streamline workflow customization.
