Claude Pro/Max plans meter Claude Code inside rolling windows (a 5-hour session window, plus weekly caps). Heavy agentic sessions — big repos, long context, many tool calls — hit the window early; it unblocks automatically when the window resets.
Agentic loops are what burn the window: every tool result re-enters context. The same task done with smaller context lasts several times longer before hitting the cap.
Since August 2026 you CAN point Claude Code at a different endpoint: Standard Compute serves the Anthropic Messages API (/v1/messages) with Claude 5-family models on a flat monthly price — set ANTHROPIC_BASE_URL to https://api.stdcmpt.com and Claude Code runs with no 5-hour window and no weekly cap. Alternatively, open agents like OpenCode, Cline and Aider run on the same flat-rate endpoint via the OpenAI-compatible base URL.
The session window is rolling (~5 hours from when usage started), and the error message shows the exact reset time. Weekly caps reset on their own schedule.
Yes — since August 2026. Claude Code talks the Anthropic Messages API, and providers that serve that format work via the ANTHROPIC_BASE_URL environment variable. Standard Compute serves Claude 5-family models this way on a flat monthly price with no session windows. Anthropic API billing (pay-per-token) also removes the plan window, but the bill scales with usage.
