o1 vs Solar Pro 3
Updated October 21, 2026. 8 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.
o1 has the edge where the context window is larger, 200K against 131K tokens, and where what matters is τ²-Bench Telecom or Humanity's Last Exam (Artificial Analysis run), where it leads.

Benchmark by benchmark
First the score: boards each model leads, per category, where both have a result. Then every board, a category to a fold; bars are each result on a 0 to 100 scale, so compare the two in a row, not one row with another.

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 Pro 3 costs less
Repository review
50K input + 3K output tokens
Solar Pro 3 costs less
Agent loop
200K input + 10K output tokens
Solar Pro 3 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 o1 better than Solar Pro 3 for coding?
Neither model has a coding score yet, so the two cannot be ranked on coding. o1 has the edge where the context window is larger, 200K against 131K tokens, and where what matters is τ²-Bench Telecom or Humanity's Last Exam (Artificial Analysis run), where it leads.
Which is cheaper, o1 or Solar Pro 3?
o1 costs $15.00 per million input tokens and $60.00 per million output tokens; Solar Pro 3 costs $0.15 and $0.60. Cost per solved task is known for neither of them.
Which has the bigger context window, o1 or Solar Pro 3?
o1, with 200K tokens against 131K.
How many benchmarks is the o1 vs Solar Pro 3 comparison based on?
8 benchmarks have a result for both models as of October 21, 2026. o1's coding index rests on 0 independent benchmarks and Solar Pro 3's on 0. Where only one model has a result, the page says so instead of naming a winner.
