Claude vs Gemini
How Claude and Gemini compare on constraint stability — usage limits, pricing, model access and transparency over time.
Constraint stability only — pricing, limits, model availability, transparency. Not a capability comparison.

02 / WHICH CHANGES THE RULES LESS?
Claude keeps its numbers; Gemini loses them — that's the cleanest way to separate the two. Claude's adjustments come numbered and mostly announced: two 7-day weekly caps added on 2025-08-28, a silent weekday peak-hour depletion on 2026-03-23 that throttled roughly 7% of users, then a 2026-05-06 reversal that doubled the 5-hour Pro/Max limits and removed the peak throttling outright — and even the plumbing was documented when Pro's weekly limit shifted from a rolling session window to a fixed account schedule on 2026-06-11. Gemini's path is defined by numbers vanishing. On 2025-11-27 the free tier's stated '5 Gemini 3 Pro prompts/day' became 'basic access' whose limits 'may change frequently'; on 2026-05-19 fixed prompt counts gave way to opaque compute-based metering where, per users, a single prompt eats several percent of a 5-hour budget — though Gemini walked part of it back on 2026-05-28 (Flash-Lite off-quota, failed requests uncharged). The single most violent event belongs to Claude, however: the 2026-06-12 US export-control directive that disabled Fable 5 and Mythos 5 for every customer worldwide, reversed only when Fable 5 returned July 1 — external and model-specific, not a pricing choice. For anyone who needs to reason about their ceiling, Claude is the steadier hold, its limits staying quantified and its reversals explicit; Gemini trades that transparency for an elastic, unstated budget and a cheaper $7.99 AI Plus entry.
