A r/ClaudeAI post (123 upvotes, 42 comments) from a user who had not touched Sonnet in three months reports that moving their workload to Sonnet 5 removed practical rate-limit pressure on a Max subscription entirely. The post explicitly frames itself against community criticism of Sonnet 5 and against GPT-5.6 Luna's 80% price cut on July 30 ($1/$6 down to $0.20/$1.20). The builder-relevant pattern here is model-tier arbitrage inside a fixed subscription: the constraint people optimize is quota consumption rate, not per-token price, and that changes which model they reach for by default.
