Upstage has released Solar Open 2, an open-source LLM optimized for AI agent tasks, requiring only two NVIDIA H200 GPUs versus 16 B200s for competing models, and outperforming DeepSeek V4 Flash and Mistral Medium 3.5 on agent benchmarks. The model, developed through South Korea's sovereign AI foundation project, will be deployed across Daum (10M+ weekly users), local government services, and industry-specific applications in finance, law, and healthcare.
This Wire brief sits within Fusion42's coverage of AI Frontier Models and AI Agents. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.
◆ The Wire takeaway
If you're building AI agents, you just lost the compute cost excuse. Solar Open 2 runs on two GPUs instead of sixteen; that's now your baseline for licensing decisions and customer pricing models.
