Happy to see #SolarPro2 has achieved a top-18 ranking in the @yupp_ai among frontier models, earning recognition as the ultimate in user satisfaction. This ranking reflects direct user feedback and votes, widely regarded as the most objective evaluation method for large language models. Meet SolarPro2 at lnkd.in/gETGZyF6. Upstage is preparing SolarPro3 to secure a top 10 position very soon. @pankaj, thanks for the wonderful service.

Upstage AI launches Solar Pro 2 reasoning model at competitive pricing
By

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

Upstage Launches Solar-Pro2 Frontier Model with Advanced Reasoning
By

Finally, @upstageai is proud to announce the launch of its #Frontier model #SolarPro2. We sincerely thank everyone who used our solar-pro2-preview and provided valuable feedback. Leveraging your input, we have incorporated newly developed learning methodologies, enhanced data curation techniques for improved data quality, general reasoning data synthesis methods, and verifiable reward technologies to create this advanced model. The Solar-Pro2 model demonstrates exceptional performance on high-difficulty reasoning benchmarks, including MMLU-Pro, Math500, AIME, and SWE-Bench. Moreover, it excels in Arena-Hard-Auto, a rigorous evaluation framework adapted from LMSYS’s LLMArena, which focuses exclusively on extremely challenging problems. Arena-Hard-Auto is not a simple multiple-choice test—it evaluates answers against those generated by top-tier models, akin to lengthy essay or subjective exams. This benchmark is so demanding that non-Frontier models often score only 10–20%, making it nearly impossible to publish results. Solar-Pro2 (reasoning) achieves a 46% score on Arena-Hard-Auto and 71% on Ko-Arena-Hard-v0.1, surpassing even the highest-quality Korean answers. Solar-Pro2 is now available for immediate use at chat.upstage.ai/ and via API (model name: solapr-pro2). To encourage broader adoption, we offer a TRY-SOLAR-PRO2 $50 credit code (valid until August 31).
