Hy3 vs Solar Mini 4
Solar Mini 4 costs 2.6x less per output token than Hy3 ($0.20 vs $0.528 per million). Updated October 22, 2026; 6 benchmarks have a result for both.
Hy3 or Solar Mini 4: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick Hy3 for work measured by Long context reasoning (AA-LCR), where it leads.

What each workload costs
Three fixed token mixes at each model's listed price, so per-token rates become a bill.
Chat turn
1K input + 500 output tokens
Solar Mini 4 costs less
Repository review
