What Amp changed

• Replaced a long video transcript of a developer workflow with a structured product breakdown.
• Introduced four distinct "Agent Modes" (Low, Medium, High, Ultra) with specific model assignments like GPT-6 Astra and Opus 5.5.
• Added a "Subagents" section featuring specialized tools for search, codebase retrieval (Librarian), and thread reading.
• Added a usage chart showing which modes are most popular among users and the internal team.
• Listed "System Models" for specific tasks like voice dictation, media analysis, and image generation.
• Added a link to a new Security Reference page regarding inference providers.

The product has shifted from a single agent interface to a specialized system. By offering different modes (Low, Medium, High, Ultra), they are letting users trade off speed and cost for reasoning power, which may attract a wider range of developer budgets.

• Added Puck, a new tool that launches and coordinates multiple agents.

• Launched dedicated apps for macOS, iPhone, and iPad with system notifications and dictation.

• Updated the model lineup to include "GPT-5.6" and "Claude Fable 5.1" (likely internal or future-facing naming).

• Simplified the homepage from a long video transcript to a clean "Quickstart" guide.

• Introduced a "Multi-Model" strategy where the tool automatically picks the best model for specific tasks.

• Added a "Raising an Agent" podcast and "Chronicle" section for brand building.

• Removed the text "Trim the bundle by 200 kB" from the header area.

• Minor text updates to the transcript of the "Day in Amp" video regarding file spot-checks and testing procedures.

Amp is shifting from a web-based tool to a multi-platform ecosystem. By adding mobile apps and a coordinator named Puck, they are trying to make AI coding agents a constant part of a developer's day, not just a tab in a browser.

The removal of a specific performance claim ("Trim the bundle by 200 kB") from the top of the page suggests a shift in marketing focus or an update to the product's technical footprint.

• Added a new status or update line: "Trim the bundle by 200 kB" at the top of the main content area.
• Minor text truncation in the transcript section regarding file spot-checks and testing procedures.

Amp is focusing on performance and speed. A smaller bundle size means the tool loads faster for developers, which is a key selling point for development environments.
