Claude rate limits are triggered when you send too many messages too quickly or exceed your plan's hourly/daily cap. Wait for the limit window to reset, slow down your request pace, and upgrade to Claude Pro or the API for higher thresholds.
Claude's usage limit resets on a rolling window — typically a few hours for free users. To continue: wait for the reset, upgrade to Claude Pro for a much higher cap, or use shorter messages to preserve your remaining quota.
Perplexity rate limits are triggered when you send too many searches too quickly or hit your plan's daily Pro search cap (300/day for Pro users). Wait for the throttle to clear, switch to Quick search (unlimited), or slow down your request pace.
Perplexity Pro gives you 300 Pro searches per day and unlimited Quick searches. Limits apply per model — more powerful models like GPT-4o and Claude Opus have lower caps. If you hit a limit, switch to a lighter model or wait for the daily reset at midnight UTC.
If API auth fails, verify key scope, org/project, and environment variables. Rotate the key if compromised and check rate limits.
If you hit an attachment count limit, remove older attachments, split work into multiple chats, compress files, and upgrade plan only if the limit is plan-based.
