This change dramatically increases token consumption for developers doing long-context agentic work. One user's analysis of 1,140 sessions showed cache busts jumping from 39 to 199 per day, raising daily costs from $6.28 to $15.54 — a projected $277.80 monthly increase. Anthropic's Jarred Sumner defended the change by saying shorter caches are cheaper for one-shot queries, but this doesn't hold for sustained agentic sessions. Developers can check their own JSONL logs under ~/.claude/projects/ to confirm the change, and can set CLAUDE_CODE_DISABLE_1M_CONTEXT=1 to cap context at 200k tokens as a partial workaround. ## Full article daily.dev links to this article rather than hosting it.
