DeepShift — DeepSeek Peak/Off-Peak Timer

Know when your AI costs less. Live countdown to DeepSeek V4 pricing windows inside VS Code, Cursor, Windsurf and any VS Code fork.

Peak is 09:00–12:00 & 14:00–18:00 Beijing (01:00–04:00 & 06:00–10:00 UTC); everything else — including all weekend — is off-peak at 50% off. DeepShift converts that to your local timezone.

What you see

• Status bar (bottom-right): 🟢 DS OFF · 2h 07m 42s ticks every second, or 🔴 DS PEAK · 2h 07m 42s. Weekend shows 🟢 DS OFF · Weekend · 2h 07m 42s. No background fill — emoji dot + PEAK/OFF text keeps it readable on light/dark themes.
• Hover tooltip: DeepSeek V4 state, Window ends in 2h 07m, Pricing USD per 1M output — Flash: peak $1.32 · off-peak $0.66 / Pro: peak $3.96 · off-peak $1.98 on separate rows, plus 🇵🇰 Local vs 🇨🇳 Beijing times with country flags. Minute-stable so hover doesn't jitter while the bar ticks.
• Click → panel: Current state, Next / Then, Best off-peak window (today→tomorrow), Today's schedule in your TZ (Asia/Karachi → 06–09 Peak), Should I run now?, and pricing. Copy current status / Copy today's schedule included.
• Alerts: deepshift.notifyBeforePeakStarts and deepshift.notifyBeforeOffPeakStarts (default 10 min each), once per transition. Diagnostics via DeepShift: Diagnose Timezone.

Works via standard StatusBarItem/ThemeColor/MarkdownString/QuickPick APIs — no webviews, no runtime deps.
