Amp June 18, 2026 Changelog

The "Librarian" is an AI tool that digs through complex code and documentation to find specific answers. This update matters to anyone who uses it to research technical questions, because you now get your answers much faster and for half the price, without losing any accuracy.

What's new

• New AI engine: The Librarian now runs on GPT-5.5. It uses a "no reasoning" setup, which means it skips the internal step-by-step thinking process and jumps straight to finding answers.
• Live connection: It now uses "websocket mode." A websocket is a live, always-on connection between your computer and the server, which cuts down on the back-and-forth delay when loading information.
• Parallel exploration: The system prompt (the hidden instructions telling the AI how to behave) was updated to encourage the AI to multitask. It now fires off about 8 tool calls (search requests) at the exact same time, up from just 3 before.

Improvements

• Way faster searches: The Librarian used to take about 15 back-and-forth "turns" to wrap up a search, taking roughly 4 minutes. Now, it finishes in about 5 turns and takes just over a minute.
• Cheaper to run: The average cost to run a search dropped from $1.21 down to $0.69. In one test case comparing a complex question about Kubernetes software, the cost dropped from $1.08 to $0.47.
• Steady quality: Even though it's moving faster, the AI still gives just as good of an answer. Its quality score actually went up a tiny bit, from 0.47 to 0.48.
