Super happy to see #solarpro2 is positioned among the top models in artificial analysis. Check it out at chat.upstage.ai. Artificial Analysis (@ArtificialAnlys) 🇰🇷 South Korean AI Lab Upstage AI has just launched their first reasoning model – Solar Pro 2! The 31B parameter model demonstrates impressive performance for its size, with intelligence approaching Claude 4 Sonnet in 'Thinking' mode and is priced very competitively Key details: ➤ Hybrid reasoning: The model offers optionality between 'reasoning' mode and standard non-reasoning mode ➤ Korean-language ability & Sovereign AI: Based in Korea, Upstage announced superior performance in Korean language evaluations. This release aligns with countries' interests to develop sovereign AI capabilities ➤ Pricing: Competitively priced at $0.5/1M tokens (input & output), significantly cheaper than comparable models including Claude 4 Sonnet Thinking ($3/$15/M input/output tokens) and Magistral Small ($0.5/$1.5/M input/output tokens) ➤ Proprietary: @upstageai has not released the model weights, though they have open-sourced previous Solar Pro models. Whether they will release Solar Pro 2's weights remains unclear as it wasn't mentioned in their announcement — https://nitter.net/ArtificialAnlys/status/1945961441888231709#m
