This is that report — ten days of pushing Anthropic’s most powerful model on real, long, multi-step coding work, right through the window where it’s been included in paid subscriptions.\n\nThe timing of this piece matters more than usual, so let me put it first: **included Fable 5 access on Pro, Max, Team, and premium Enterprise plans ends July 12 at 11:59:59 PM PT** — extended once already from the original July 7 cutoff. From July 13, using it means prepaid usage credits at full API rates: $10 per million input tokens, $50 per million output — exactly double Opus 4.8, and the most expensive pricing Anthropic has ever listed for a generally available model.\n\nSo here’s what ten days of heavy use actually taught me — about the model, and about the two walls I did and didn’t hit.", "url": "https://wpnews.pro/news/i-pushed-claude-fable-5-hard-for-ten-days", "canonical_source": "https://pub.towardsai.net/i-pushed-claude-fable-5-hard-for-ten-days-49dffa13dacc?source=rss----98111c9905da---4", "published_at": "2026-07-17 14:31:02+00:00", "updated_at": "2026-07-17 14:57:19.880619+00:00", "lang": "en", "topics": ["large-language-models", "ai-products", "ai-policy"], "entities": ["Anthropic", "Claude Fable 5", "Opus 4.8"], "alternates": {"html": "https://wpnews.pro/news/i-pushed-claude-fable-5-hard-for-ten-days", "markdown": "https://wpnews.pro/news/i-pushed-claude-fable-5-hard-for-ten-days.md", "text": "https://wpnews.pro/news/i-pushed-claude-fable-5-hard-for-ten-days.txt", "jsonld": "https://wpnews.pro/news/i-pushed-claude-fable-5-hard-for-ten-days.jsonld"}}
