Command A vs Solar Mini 4
Updated October 21, 2026. 4 benchmarks have a result for both. Coding is ranked on the Vibe Coding Index; every other board is shown as published.
Decision reading
Neither model has a coding score yet, so the two cannot be ranked on coding.
Command A has the edge where what matters is SciCode or AA Intelligence Index, 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
50K input + 3K output tokens
Solar Mini 4 costs less
Agent loop
200K input + 10K output tokens
Solar Mini 4 costs less
Listed OpenRouter rates, without cache or batch discounts. A workload that does not fit a model's context window would need splitting.

Questions
Is Command A better than Solar Mini 4 for coding?
Neither model has a coding score yet, so the two cannot be ranked on coding. Command A has the edge where what matters is SciCode or AA Intelligence Index, where it leads.
Which is cheaper, Command A or Solar Mini 4?
Command A costs $2.50 per million input tokens and $10.00 per million output tokens; Solar Mini 4 costs $0.05 and $0.20. Cost per solved task is known for Command A only.
Which has the bigger context window, Command A or Solar Mini 4?
Solar Mini 4, with 524K tokens against 256K.
How many benchmarks is the Command A vs Solar Mini 4 comparison based on?
4 benchmarks have a result for both models as of October 21, 2026. Command A's coding index rests on 1 independent benchmark and Solar Mini 4's on 0. Where only one model has a result, the page says so instead of naming a winner.
