Qwen3.8 Max (0902) vs Solar Mini 4
Qwen3.8 Max (0902) leads Solar Mini 4 on the Artificial Analysis Intelligence Index, 45.4 to 24.1, and Solar Mini 4 costs 30.0x less per output token ($0.20 vs $6.00 per million). Updated October 22, 2026; 7 benchmarks have a result for both.
Qwen3.8 Max (0902) or Solar Mini 4: which to pick
Only Qwen3.8 Max (0902) has a coding score, 62.4 on the Vibe Coding Index; Solar Mini 4 has none, so the two cannot be ranked on coding.
Pick Solar Mini 4 for output tokens 30.0x cheaper ($0.20 vs $6.00 per million) and work measured by Long context reasoning (AA-LCR), where it leads.
