Upstage ends Solar Pro 4 free promo — rates rise to 90%-off list
What happened
Between the Aug 10, 2026 and Aug 17, 2026 captures of Upstage's pricing page, Pulse recorded one change: Solar Pro 4's fully free launch promo ended 2026-08-10 and was replaced by a 90%-off promo, so effective rates rose from $0 to Input $0.03, Cached $0.006 and Output $0.12 per 1M tokens. List prices are unchanged at $0.30 / $0.06 / $1.20 per 1M tokens; standard pricing resumes 2026-09-11 (UTC). Pulse files it as a pricing change (price increase) with an upward 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 ends Solar Pro 4 free period — now 90% off until Sep 10, full rates from Sep 11" (Aug 17, 2026). Before that Pulse recorded "Upstage API: File Search pricing dropped to Free + Embed trial/EOL extended" (Jul 28, 2026), "Upstage: Embed 2 post-promo rate cut ($0.10→$0.02/1M tokens)" (Jul 13, 2026) and "Upstage API: Embed 2 post-promo rate cut ($0.10→$0.02/1M tokens)" (Jul 13, 2026). Upstage has been tracked since 2026-04-29.
In the same window Together AI, Mistral AI, OpenAI, Anthropic and Google also changed their AI & Machine Learning pricing pages. Those moves are listed further down, and the Pulse Agent can compare them side by side.
