OpenAI Introduces GPT-6.1 Sol, Bringing Near-Astra Performance at Lower Cost — OpenAI’s GPT-6.1 Sol improves coding, document analysis, computer use, and business automation, approaching GPT-6 Astra’s performance on several evaluations at one-fifth of its standard token prices. OpenAI also reports gains in factual accuracy and safety, while Astra remains stronger for the hardest scientific tasks. The model is available in ChatGPT Work, Codex, and the API, with a faster Ultrafast version planned. OpenAI ↗

My takeaway: I didn't expect GPT-6.1 Sol to be released just a week after GPT-6 Sol. That feels like a very fast pace. Unfortunately, if model releases every week or even more frequently become the norm, we'll have less time to evaluate each model (I hope not). According to benchmark data from Artificial Analysis, GPT-6.1 Sol performs nearly as well as GPT-6 Astra at a much lower cost, though its output speed is slightly slower than GPT-6 Sol's.

OpenAI DevDay Summary:

• Dots: Always-on agents that learn your priorities and handle ongoing work.
• GPT-6.1 Sol: Near-Astra performance on selected tasks at one-fifth of Astra’s standard token prices.
• Ultrafast: Up to 8× faster token generation in Codex and 6× in the API.
• Private Intelligence: Stronger business data protections, with confidential computing coming in a preview.

My takeaway: Just FYI, Dots is OpenAI's new personal assistant agent. You can think of it as similar to Meta's Muse or xAI's Grok bot. For Pro 500, I saw a post from a user who said they had used up their entire usage allowance within 30 minutes. That's just one reported experience, but it's a reminder to keep an eye on your usage when running tasks with Ultrafast.
