GPT-6 Sol Pro or o3 Mini: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick GPT-6 Sol Pro for a larger context window (1.05M against 200K tokens).
No benchmark has tested both yet. GPT-6 Sol Pro has none yet; o3 Mini on Aider polyglot, SWE-bench Verified and SWE-bench Lite. Compare them on price and context instead.

Benchmark by benchmark
Every board either model has a result on, a category to a fold; bars are each result on a 0 to 100 scale. Only one model is measured on each, so no row names a leader.

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
o3 Mini costs less
Repository review
50K input + 3K output tokens
o3 Mini costs less
Agent loop
200K input + 10K output tokens
o3 Mini costs less
Listed OpenRouter rates, without cache or batch discounts. A workload that does not fit a model's context window would need splitting.
