Upstage boosts Solar Mini 4 discount to 70%, sunsets Solar Pro 3 and Pro 2
What happened
Between the Sep 28, 2026 and Oct 5, 2026 captures of Upstage's pricing page, Pulse recorded 2 changes: Solar Mini 4 launch discount changed from 50% off until Oct 22, 2026 (then reverting to standard pricing) to 70% off until Oct 10, 2026, followed by a continuing 50% off instead of standard pricing; Solar Pro 3, Solar Pro 2, and the legacy Solar Mini model each now show an "End of service on 2026-10-30 (KST)" notice, announcing their discontinuation in favor of Solar Pro 4 and Solar Mini 4. Pulse files it as a pricing change (plan removed, discount change) with a downward direction. Pulse's latest capture (Oct 26, 2026) lists Explore at $100, Build at $500, Scale at $5,000, Solar Pro 4 at $0.36 per 1M output tokens + $0.09 per 1M input tokens and Solar Pro 3 at $0.15 per 1M input tokens + $0.6 per 1M output tokens.
It lands the same day as Upstage's previous change, "Upstage API deepens Solar Mini 4 promo to 70% off, sunsets Solar Pro 3" (Oct 5, 2026).
