GPT-6.1 Sol vs Astra and Opus 5.5: cost and speed on the same task
In a same-task comparison, GPT-6.1 Sol took 10 minutes and cost $1.50, Astra took 25 minutes and $11, and Opus 5.5 took 45 minutes and $13.50, with the author calling Sol the best value but less capable than Opus.
GPT 6.1 sol is the cheapest frontier model it’s performing way better than i expected, coming close to astra at a friction of a cost tested 6.1 sol, sonnet, opus and astra but results came out different > 6.1 sol took 10 mins and cost $1.50 > sonnet 5.5 took about 50 mins and cost $9.21 > astra took 25 mins and cost $11 > opus 5.5 took 45 mins and cost $13.50 openai cooked harder with this model it doesn’t come close to opus 5.5, but price and speed wise 6.1 sol wins
