OpenAI Launches GPT-6.1 Sol with Lower Prices and High Performance
OpenAI has launched GPT-6.1 Sol, a new mid-range AI model designed for complex agent workflows, offering high performance at lower token prices.
What happened?
OpenAI has launched GPT-6.1 Sol, a mid-range AI model intended for complex agent-based workflows. The model delivers performance comparable to top-tier models but at a significantly lower price. The standard API pricing is set at 2 dollars per million input tokens and 10 dollars per million output tokens. Furthermore, the model reached a 75.2 percent pass rate on the DeepSWE v1.1 benchmark during high-reasoning tasks.
Key facts

| Cachad indata | 0,10 USD per miljon tokens |
| DeepSWE v1.1 resultat | 75,2 % godkännandegrad |
Why it matters
Reduced pricing for complex reasoning and coding makes it significantly cheaper to run large-scale agent workflows in production. With features such as prompt caching—where cached input costs 0.10 dollars per million tokens, representing a 95 percent reduction compared to the standard price—computational costs are significantly lowered for recurring instructions.
Who is affected?
The model primarily impacts software developers, AI engineers, and companies building autonomous agent workflows or using tools such as Codex and ChatGPT Work. Swedish tech companies integrating OpenAI's API will also gain access to more cost-effective computational capacity.
Impact on the EU
The GPT-6.1 Sol model is available via OpenAI's standard API, ChatGPT Work, and Codex, making it accessible to developers and companies in the EU. No specific geographical restrictions for the EU region have been announced at launch.
What else you should know
The launch of GPT-6.1 Sol demonstrates a continuing trend where AI providers are pushing to lower costs for advanced agent-based coding and problem-solving without compromising performance in complex workflows.
