| Notes | Solar model family (Solar Pro / Solar Mini per cheahjs README; console landing page now advertises Solar Pro 3, 102B MoE). Fetched console docs pages were sparse; base URL api.upstage.ai/v1 is the widely documented OpenAI-compatible endpoint and is unconfirmed on this pass. Base URL confirmed live 2026-07-17: GET /models returned HTTP 401 (endpoint exists, auth required). Guide pass 2026-07-17: console (Playwright) demos solar-pro3; cataloged solar-pro2/solar-mini may be superseded — update candidate. Model-churn recheck 2026-07-18 (official models catalog + Solar Pro 3 page, Playwright-rendered): lineup is Solar Pro 3 (alias solar-pro3; versions solar-pro3-260323 released 2026-03-23 and solar-pro3-260126; 128K context, 102B MoE/12B active, reasoning + function calling), with Solar Pro 2 and Solar Mini STILL listed as current in the generative-intelligence catalog — no renames/retirements found, so no deprecated flags set. solar-pro3 added as a new model record. Solar Pro 3 is paid per-token ($0.15/1M in, $0.60/1M out) — free access remains via the $10/3-month trial credit. |
