Users are reporting that Anthropic's Claude Opus 4.8, when the "Thinking" feature is enabled, consumes context windows at a dramatically accelerated rate, up to 40-60 times faster than previous versions. This rapid drain is attributed to the "Thinking" function being permanently enabled in Opus 4.8, causing context to snowball with each turn. In contrast, Opus 4.7's adaptive "Thinking" only activates when necessary, preventing excessive context accumulation. Users experiencing this issue can revert to Opus 4.7 or disable the "Thinking" feature in Opus 4.8 to mitigate the rapid context window depletion. AI
IMPACT Users may need to disable a feature or revert to an older model version to manage context window usage effectively.
