Anthropic raises context windows to 1M, opens Projects to Free tier in Pro/Max plan revamp
Context window across Free, Pro, and Max plans increased from a flat 200k tokens to "Up to 1M, varies by model." The Free tier gained access to Projects (up to 5) for the first time.

WHY IT MATTERS
Anthropic is using its free tier as an acquisition lever while simplifying its paid-tier structure elsewhere. Watch whether the 1M-token ceiling narrows in practice by model, and whether competitors follow with their own free-tier context bumps, given how common free-plan moves are across the index right now.
BY THE NUMBERS
- 56 days since Anthropic's last change - vs. its own ~38-day average
- 5th Free-tier upgrade since Jan 2025 (after memory, web search, desktop extensions)
- Context window: 200k flat -> 'up to 1M, varies by model' across Free/Pro/Max
- Free-plan pattern moves are 5.8% of all tracked changes (322/5515) in 6 months
THEIR RATIONALE
Anthropic frames this as a broad upgrade to Pro and Max plans alongside added Free-tier value, continuing a pattern of periodically opening previously paid capabilities — like memory and web search — to lower tiers as a growth lever, even as it trims some paid-tier options in the same release.
THE SIGNAL
This is Anthropic's first pricing-page change in 56 days, well past its own roughly 38-day average cadence, suggesting a bundled release rather than incremental tweaks. Giving Free-tier users Projects and a bigger context window extends a well-established pattern: Anthropic has now expanded Free-tier entitlements five times since tracking began in January 2025, including moving cross-conversation memory to Free in March and adding web search to Free in mid-2025. But the same release quietly tightens the paid side — dropping Max's annual billing option and removing Cowork from the comparison table.
IN CONTEXT
Anthropic's free tier keeps absorbing capabilities once reserved for paid plans — this follows March's move of cross-conversation memory to Free and 2025's addition of web search to Free, now joined by Projects and a 1M-token context ceiling. The gap since Anthropic's last change is telling: 56 days, well past its own ~38-day average, suggesting this was bundled as a single coordinated release rather than incremental tweaks. Elsewhere in the index, free-plan changes are a well-worn pattern — 5.8% of all changes tracked in six months, with movers like Zoho and HubSpot doing similar — but Anthropic pairs its free-tier generosity with a quieter tightening: Max plans lose their annual billing option in the same release.
