OpenAI Launches GPT-6.1 Sol with Lower Prices and High Performance
OpenAI has launched GPT-6.1 Sol – a new mid-tier AI model for complex agent workflows that offers high performance at lower token prices.
What happened?
OpenAI has launched GPT-6.1 Sol, a mid-tier AI model designed for complex agent-based workflows. The model delivers performance comparable to flagship models but at a significantly lower price. The standard API price is set at 2 dollars per million input tokens and 10 dollars per million output tokens. Furthermore, the model achieved 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 for recurring instructions are substantially lowered.
Who is affected?
The model primarily targets software developers, AI engineers, and companies building autonomous agent workflows or using tools such as Codex and ChatGPT Work. Swedish tech companies integrating the OpenAI API will also gain access to more cost-effective computing power.
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 within the EU. No specific geographical restrictions for the EU region have been announced at launch.
What else you should know
The release of GPT-6.1 Sol reflects a continued trend where AI providers seek to push down prices for advanced agent-based coding and problem-solving without compromising performance in complex workflows.
