Claude Reportedly Injects Massive Context Server-Side

MaleficentSurprise · reddit · 2026-07-19

Reddit users report Claude throwing errors almost daily in new conversations: This request exceeds Claude's context limit by about 4-6M tokens, affecting web, desktop, iOS, and incognito modes.

Further investigation reveals the error isn't triggered by user input, but rather by the server injecting a 19MB / 4.8M token object during prompt assembly; different models behave identically, independent of the payload. Worse, on usage-based billing accounts, this injected content is actually processed and billed if no error occurs or if it's under the context limit, potentially leading to $4 charges per message. The post also notes a lack of support response, and the author seeks to collect affected account dates, excess tokens, surfaces, and billing types to pinpoint the issue.
