Track the latest models, compare frontier and open-source LLMs, and download open-weight models — then run any of them on Semifly with tokens, GPU servers, and AI Foundry.
Every major lab grouped by camp — US vs China, proprietary vs open — with each family’s key versions and years. The China open-weight branch is by far the busiest.
Key versions per lab, hand-curated as of 2026-06. Refreshed as new flagships ship.
Every model placed by quality (Artificial Analysis Intelligence Index) and input price — top-left is the value sweet spot. As of 2026-06-18.
LMArena Elo of the #1 proprietary model (blue) vs the #1 open-weight model (orange), 2023–2026. Open-weight nearly drew level in early 2025; since then the open #1 has been almost entirely Chinese — DeepSeek, Qwen, GLM, Kimi.
