Upstage cuts Solar Pro 4 promo to 50% off; Solar Mini 4 discount ends
What happened
Between the Oct 5, 2026 and Oct 26, 2026 captures of Upstage's pricing page, Pulse recorded 2 changes: Solar Pro 4 launch promo cut from 70% to 50% off, now until further notice (promo input $0.09→$0.15/1M, output $0.36→$0.60; list unchanged). Solar Mini 4 launch promo ended — back to list $0.10 input / $0.40 output per 1M tokens (was $0.03 / $0.12). In detail: Solar Pro 4 launch promo cut from 70% to 50% off and extended from Oct 10 to until further notice: promo input $0.09->$0.15/1M, cached $0.018->$0.03, output $0.36->$0.60 (list $0.30/$0.06/$1.20 unchanged); Solar Mini 4 launch promo ended: card no longer shows the discount and is back to list $0.10 input / $0.01 cached / $0.40 output per 1M tokens (was $0.03/$0.003/$0.12 at 70% off, scheduled 50% off through Oct 22). Site banner still advertises the expired 50%-off-through-Oct-22 promo. Pulse files it as a pricing change (discount change, discount removed) with a neutral direction. The current page 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.
