Claude AI's deep thinking may falter in long chats due to context pressure

A user on Reddit has theorized that Anthropic's Claude models, particularly newer versions like Opus 4.7 and 5, may stop engaging in deep thinking during long conversations due to context pressure. The hypothesis suggests that as the conversation progresses, accumulated internal reasoning steps consume too much context, leading the model to default to instant answers. Switching to a different Claude model within the same chat appears to temporarily resolve the issue, possibly by clearing out model-specific reasoning history, thereby freeing up context for renewed deep thinking. AI

IMPACT Suggests a potential limitation in current LLM conversational context management that could affect user experience.
