Anthropic Doubles Claude Usage Limits During Off-Peak Hours Until March 27

Anthropic has announced a limited-time offer: from March 13 to 27, 2026, usage limits for all Claude models are doubled outside of peak hours — across all subscription tiers except Enterprise.

What Does This Mean in Practice?

Claude users on Pro, Team, and other plans get double capacity on their five-hour usage limits, but only during off-peak hours. The exact hours aren't specified, but typically include nighttime and early morning periods.

Context: The Pentagon Ban

The timing is notable. This announcement comes shortly after Anthropic was blocked from the Pentagon contract that had made Claude the first frontier AI model cleared for classified use in the US military. Time Magazine recently published a major feature on Anthropic as "the world's most disruptive company" — covering the dramatic rise and fall of the Pentagon relationship.

Claude 1M Token Context Now Standard

In parallel, Anthropic has confirmed that the 1 million token context window for Claude Opus 4.6 and Claude Sonnet 4.6 is now generally available with standard pricing — eliminating the previous premium surcharges for long-context prompts.

For Developers and Enterprises

Double capacity during off-peak hours is a practical advantage for batch jobs, overnight analysis, and large document processing tasks. Combine with the 1M token context window for maximum impact on large datasets.

The offer runs until March 27, 2026.
