GPT-6.1 Sol supersedes GPT-6 Sol in just a week, offering near‑Astra intelligence

GPT-6.1 Sol replaces GPT-6 Sol after just a week, offering near‑Astra intelligence.
OpenAI has quietly retired its GPT‑6 Sol model, replacing it with GPT‑6.1 Sol just seven days after the former’s launch. The new version is billed as “near‑Astra” intelligence, scoring only one point shy of the flagship GPT‑6 Astra on OpenAI’s internal Intelligence Index while costing less than a quarter of the “Cost per Task” metric.
Pricing for GPT‑6.1 Sol mirrors GPT‑6 Sol at $2 per million input tokens and $10 per million output tokens, but the cache‑read discount has been nudged up from 90 % to 95 %. According to OpenAI’s product page, the upgrade delivers comparable performance for coding, computer use and professional workloads at roughly one‑fifth of Astra’s standard API token prices.
The rapid turnover underscores a shift in how AI providers signal value: rather than relying solely on headline benchmark scores, the industry is increasingly foregrounding total task cost. For rev‑ops teams, technical architects and other business users, the move suggests that today’s “best” model may be superseded within weeks, prompting continuous reassessment of model selection and budgeting strategies.
What to watch next is whether OpenAI will sustain this cadence of incremental releases and how competitors respond. Analysts will be looking for any hidden trade‑offs in the “near‑Astra” claim, such as latency or feature limitations, and for signals that the pricing structure might evolve further. The development also adds a new layer to the broader AI race, where speed of iteration and cost efficiency are becoming as decisive as raw capability.
