OpenAI's Sol Undercuts Its Own Flagship
OpenAI releases GPT-6.1 Sol, a model that approaches Astra's coding and computer-use capabilities while costing only one-fifth of Astra's token price.
#OpenAI#GPT-6#API#Pricing#Agents

š„ What happened
OpenAI shipped GPT-6.1 Sol, a mid-tier model claiming near-Astra performance on agentic coding, computer use, and professional work. Pricing: $2 input, $10 output, $0.10 cached input per million tokens. Live today in the API, ChatGPT Work, and Codex.
š” Why it matters
Cached reads now cost 5% of the uncached input rate, down from 10% ā and agents resend the same system prompt and tool schemas on every step, so that's where the real savings land. On Terminal-Bench Science, Sol costs $5.47 per task versus $23.21 for Opus 5.5 and $23.80 for Astra. Astra only wins on the hardest research.
ā” Our take
OpenAI is cannibalizing its own flagship before Anthropic or Google get the chance. Anyone still booking Astra pays 4x for a fraction of the tasks ā that's not a price, that's a statement.
