Four-panel chart of time to first token versus input context up to 900,000 tokens for GPT-5.6 Sol, GPT-6 Astra, GPT-6 Sol and GPT-6.1 Sol, with Student-t fits. GPT-6.1 Sol starts higher but rises more slowly, reaching about 15 seconds at the longest context versus about 17 seconds for GPT-5.6 Sol and GPT-6 Sol.

TLDR

Epoch AI Research says OpenAI halved GPT-6.1 Sol's cached-input price compared with GPT-6 Sol. Its measurements also show faster handling of long prompts. The group asks whether GPT-6.1 Sol has a new architecture.
