Solar Pro 22B

Solar Pro 22B is a 22-billion-parameter dense language model from Korean AI company Upstage, released in October 2024. It targets single-GPU production deployments — fitting on one A100 or H100 under int8 quantization — with particular strength in document understanding and Korean-English bilingual tasks, making it a practical choice for teams processing mixed-language enterprise documents without multi-GPU overhead. The 4K context window is a real constraint for long-document pipelines, so evaluate it against your chunking strategy before committing. Upstage released it under CC-BY-4.0, which is unusually permissive for a model at this scale: attribution only, no share-alike, no commercial restrictions. For teams that need a compact, commercially deployable bilingual model with clean licensing, Solar Pro 22B is worth benchmarking.
