1 unannounced change

Claude has become more restrictive over time, mainly in model availability.

Most noticeable: Anthropic's newest and most capable models became unavailable to every customer overnight by federal directive — users building on Fable 5 / Mythos 5 must migrate with no notice. First known instance of the US government forcing a deployed frontier model offline.

02 / ANALYSIS

In August 2025 Anthropic layered two seven-day weekly caps on top of the existing rolling five-hour limits, explicitly to curb heavy Claude Code usage — the structural tightening that anchors this record. Since then the limits have swung both ways: a temporary holiday doubling over the 2025 turn of year, then a quieter and more concerning move in March 2026, when weekday morning allowances began draining faster. That silent, peak-hour throttle was only later confirmed. By May 2026 it had been reversed and five-hour limits doubled for Pro and Max. Transparency here is mixed — reset logic was eventually fixed to a predictable weekly schedule, but the one unannounced change is a meaningful mark against it. The sharpest event was not Anthropic's doing at all: in June 2026 a US government export-control directive forced Fable 5 and Mythos 5 offline for every customer worldwide overnight, the first known instance of a deployed frontier model being pulled by federal order, with access returning July 1. Model and price changes otherwise trend neutral-to-favorable, including Sonnet 5's introductory pricing below its predecessor. In short, Claude's limits are actively managed and have loosened net over time, but they are adjusted frequently, occasionally without announcement, and — uniquely here — a specific model's availability can vanish for reasons entirely outside the vendor's control. Build on the platform, but do not hard-wire a dependency on any single named model.
