Frequently asked questions

GPT-6.1 Terra and Qwen1.5 don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Only GPT-6.1 Terra has a verified first-party API price: $1.00 per million input tokens and $5.00 per million output tokens. No pay-as-you-go API rate is tracked for Qwen1.5. Qwen1.5 shipped 995 days before GPT-6.1 Terra, so benchmark comparisons should account for the intervening progress.

Context windows are 1.05M (GPT-6.1 Terra) vs 32k (Qwen1.5). GPT-6.1 Terra is closed, while Qwen1.5 is open weight.
