Only benchmarks that tested both models count toward a pick; a result only one model has is shown but not compared.

Which one for your work

Each card is decided by one number both models carry. Where only one has it, the card says so and makes no call.

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 o1-pro better than Inkling for coding?

Only Inkling has a coding score, 31.5 on the Vibe Coding Index; o1-pro has none, so the two cannot be ranked on coding. Compare them on price, context and the boards below.

Which is cheaper, o1-pro or Inkling?

o1-pro costs $150.00 per million input tokens and $600.00 per million output tokens; Inkling costs $0.975 and $4.05. Cost per solved task is known for Inkling only.

Which has the bigger context window, o1-pro or Inkling?

Inkling, with 524K tokens against 200K.

How many benchmarks is the o1-pro vs Inkling comparison based on?

2 benchmarks have a result for both models as of October 21, 2026. o1-pro's coding index rests on 0 independent benchmarks and Inkling's on 6. Where only one model has a result, the page says so instead of naming a winner.
