Artificial Analysis measured $2.29 per completed task — more than Opus 4.8. The gap is one setting, and the migration docs quietly remapped it.\n\nOn June 30, Anthropic cut Sonnet’s price to $2 per million tokens. Three days later, Artificial Analysis published the number that actually decides your bill: **$2.29 per completed task** — roughly double Sonnet 4.6, and about 15% more than Opus 4.8, the flagship that costs over twice as much per token.\n\nBoth numbers are true. Only one of them shows up on your invoice.\n\nI’ve written before about auditing a dual-agent stack over 90 days, and the lesson that survived that audit applies here with interest: sticker prices tell you what a token costs, and almost nothing about what your *work* costs. Sonnet 5 is the sharpest version of that gap I’ve seen a lab ship. The per-token rate went down. The per-task cost, at the settings most teams will inherit without noticing, went up past the flagship.\n\nHere’s the claim, early, so you can disagree efficiently: **which model you pick is now the secondary cost decision. The effort dial is the primary one — and if you**…", "url": "https://wpnews.pro/news/the-effort-dial-audit-pricing-sonnet-5-by-the-task-not-the-token", "canonical_source": "https://pub.towardsai.net/the-effort-dial-audit-pricing-sonnet-5-by-the-task-not-the-token-94bdbb8589aa?source=rss----98111c9905da---4", "published_at": "2026-07-07 05:58:58+00:00", "updated_at": "2026-07-07 06:04:36.709983+00:00", "lang": "en", "topics": ["large-language-models", "ai-products", "ai-infrastructure"], "entities": ["Anthropic", "Sonnet 5", "Opus 4.8", "Artificial Analysis", "Sonnet 4.6"], "alternates": {"html": "https://wpnews.pro/news/the-effort-dial-audit-pricing-sonnet-5-by-the-task-not-the-token", "markdown": "https://wpnews.pro/news/the-effort-dial-audit-pricing-sonnet-5-by-the-task-not-the-token.md", "text": "https://wpnews.pro/news/the-effort-dial-audit-pricing-sonnet-5-by-the-task-not-the-token.txt", "jsonld": "https://wpnews.pro/news/the-effort-dial-audit-pricing-sonnet-5-by-the-task-not-the-token.jsonld"}}
