The earlier caps (Team 150/day, Enterprise 1000/day) used Sonnet/Opus pricing that put max-usage above the tier's monthly revenue — a Bot with a Team subscription could out-cost €199 in Anthropic spend. Drop to 50/day Team and 200/day Enterprise; both now keep ~55-65% margin even when maxed. Pricing page Team feature line updated to match (150 -> 50). Build caps loosened slightly less since the 24h cache TTL makes most builds cache-hits. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
