Claude AI Pro plan costs surge after 1-hour chat break

A user on Reddit conducted an experiment to measure the cost of using Anthropic's Claude AI, specifically focusing on token usage and its impact on pricing. The findings indicate that continuing a conversation within the same chat session is significantly cheaper due to caching, costing roughly $0.007 to $0.015 per message. However, returning to a chat after a break of over an hour dramatically increases costs to approximately $0.157 per message, about 20 times more than continuing without a pause. The user also noted that Claude Opus is about twice as expensive as Claude Sonnet for the same task. AI

IMPACT Understanding Claude's token caching and pricing can help users optimize costs and usage patterns.

    I measured how much each "save tokens" trick actually costs on a Pro plan. Coming back to an old chat after 1h costs ~20x more.
