Anthropic boosts context window to 1M across all Claude plans
What happened
Between the Sep 14, 2026 and Sep 21, 2026 captures of Anthropic's pricing page, Pulse recorded 3 changes: Context window in the Individual comparison table jumped from 200k to Up to 1M (varies by model) across Free, Pro, Max 5x, and Max 20x plans; Free plan gained Projects access (Up to 5, was none); Max 5x and Max 20x lost the annual billing option and are now Monthly-only, while Pro keeps Monthly and annual; Claude Cowork dropped as a gated feature: removed from Pro's feature list and comparison t. In detail: Claude Cowork dropped as a gated feature: removed from Pro's feature list and comparison table; Pro now shows 'Hand off and schedule tasks', with a banner noting Cowork is now built into Claude. Pulse files it as a packaging change (package change, feature change, limit increase) with an upward direction. Pulse's latest capture (Oct 12, 2026) lists Pro at $17, Enterprise (self-serve) at $20, Team (Standard seat) at $20, Max 5x at $100 and Team (Premium seat) at $100.
It lands 4 days after Anthropic's previous change, "Anthropic raises context windows up to 1M, revamps Pro and Max plans" (Sep 17, 2026). Before that Pulse recorded "Anthropic: Fable model + context window disclosed in comparison table" (Jul 23, 2026), "Anthropic launches Sonnet 5, cuts price to $2/$10 per MTok through Aug 31" (Jul 6, 2026) and "Anthropic adds Claude AI to all consumer plan tiers" (Jun 29, 2026). Anthropic has been tracked since 2024-11-17.
