DeepSeek V3 vs o1
DeepSeek V3 costs 62.5x less per output token than o1 ($0.9594 vs $60.00 per million). Updated October 22, 2026; 5 benchmarks have a result for both.
DeepSeek V3 or o1: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick DeepSeek V3 for output tokens 62.5x cheaper ($0.9594 vs $60.00 per million) and work measured by GPQA Diamond (Epoch AI run) or OTIS Mock AIME, 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.

Questions
Is DeepSeek V3 better than o1 for coding?
Neither model has a coding score yet, so the two cannot be ranked on coding. Pick DeepSeek V3 for output tokens 62.5x cheaper ($0.9594 vs $60.00 per million) and work measured by GPQA Diamond (Epoch AI run) or OTIS Mock AIME, where it leads.
Which is cheaper, DeepSeek V3 or o1?
DeepSeek V3 costs $0.2887 per million input tokens and $0.9594 per million output tokens; o1 costs $15.00 and $60.00. Cost per solved task is known for neither of them.
Which has the bigger context window, DeepSeek V3 or o1?
o1, with 200K tokens against 164K.
How many benchmarks is the DeepSeek V3 vs o1 comparison based on?
5 benchmarks have a result for both models as of October 22, 2026. DeepSeek V3's coding index rests on 0 independent benchmarks and o1's on 0. Where only one model has a result, the page says so instead of naming a winner.
