OpenAI is testing a new ChatGPT feature called "Skills," which will be similar to Claude's feature, also called Skills.

Up until now, ChatGPT has supported GPTs, which are prompt-engineered to meet your specific needs.

On the other hand, Claude Skills are folder-based instructions that teach Claude AI specific abilities, workflows, and domain-specific knowledge.

For example, Claude has a frontend design skill plugin, which allows Claude to better understand the interface while you vibe code your web app.

According to Anthropic, Skills are:

• Composable: Skills stack together. Claude automatically identifies which skills are needed and coordinates their use.
• Portable: Skills use the same format everywhere. Build once, use across Claude apps, Claude Code, and API.
• Efficient: Only loads what's needed, when it's needed.
• Powerful: Skills can include executable code for tasks where traditional programming is more reliable than token generation.

GPT might soon get something similar, and it will also be called Skills.

As spotted on X by Tibor, Skills in ChatGPT are codenamed "hazelnuts" and will be available as slash commands, including a Skills editor and an option to convert a custom GPT into a skill.

It's unclear when Skills will begin rolling out, but it's likely planned for a January 2026 release.
