What you get

Upstage Solar LLM API; $10 free credit on signup, no card

Free models

solar-pro-3, solar-mini

Limits, in the vendor’s words

$10 signup credit (see console for validity); pay-as-you-go after. console.upstage.ai is a client-rendered docs site — 535 characters of text survive with its scripts removed — so “$10 in free credit” is read out of the payload the page ships rather than out of anything a reader sees, and it is declared as a machinery keyword to say so. Neither upstage.ai/pricing nor the Solar Pro product page carries the phrase at all (all three read 2026-09-08)
