OpenAI releases GPT-6.1 Sol, priced one-fifth of GPT-6 Astra
OpenAI announced the release of GPT‑6.1 Sol, an updated version of GPT‑6 Sol that aims to match the performance of GPT‑6 Astra in agentic coding and professional work. The company highlighted that the standard API text pricing for GPT‑6 Astra is $10 per 1 million tokens for input, $1 for cached input, and $50 for output, while GPT‑6.1 Sol is priced at $2 for input, $0.10 for cached input, and…
Key points
- OpenAI releases GPT‑6.1 Sol, priced one‑fifth of GPT‑6 Astra for standard input and output
- GPT‑6.1 Sol costs $2 input, $0.10 cached input, $10 output per 1 million tokens
- Total cost depends on error rates, rework, and decision‑making delays, not just unit price
The article cautions that unit price alone does not determine total cost. It notes that factors such as error identification, rework, and decision‑making delays can affect overall expense. OpenAI recommends evaluating tasks based on four criteria—instruction vagueness, loss significance, task repetition, and verification time—to decide whether to use Sol, Astra, or Luna for routine work.
The release is positioned as a cost‑effective option for daily tasks while reserving the higher‑performance Astra for high‑stakes scenarios. Users are advised to review the official OpenAI terms and pricing pages before adopting the new model.
