At ~500 tokens per message on average, Haiku costs approximately $0.0024 per message round-trip. Sonnet costs approximately $0.009 per message round-trip. Pro tier users get unlimited Sonnet at $29/month — covering approximately 3,200 Sonnet messages per month before the margin inverts.
Global daily budget cap: $500 across the entire platform. If all users collectively burn $500 in a single day, new LLM requests return a graceful 'budget exceeded' response. This has never triggered in production but exists as a safety net.
