Model Card
GPT-6 Sol Pro is OpenAI's higher-effort configuration of GPT-6 Sol, the mid-tier model in the GPT-6 family released September 22, 2026 alongside the flagship GPT-6 Astra. Following the pattern OpenAI used for GPT-5.6 Sol Pro and GPT-6 Astra Pro, it runs the same underlying Sol model with reasoning effort set to pro rather than a separate, larger checkpoint, which is why it carries identical pricing to base Sol.
At $2 per million input tokens and $10 per million output tokens, it shares Sol's 1,050,000-token context window and 128,000 max output tokens, along with function calling and adjustable reasoning effort.
Sol Pro suits complex development work, coding, computer use, and data analysis where response quality on harder requests matters more than shaving cost or latency.

More AI Models From OpenAI
GPT Image 2.6 Flare
GPT Image 2.6 Flare is OpenAI's speed-oriented image generation and editing model, released November 4, 2026 in the GPT Image 2.6 family alongside GPT Image 2.6 Sunburst. OpenAI says both 2.6 models generate images 50% faster than before, and Flare can produce an image in as little as six seconds at low quality. OpenAI positions Flare for posters, product imagery, and other layout-focused work. The API supports image markup, so requests can mark specific areas to change, and a complexity setting that controls how much planning the model does. OpenAI recommends low complexity for most quick edits and medium or high for scenes with many elements or constraints. At low quality and 1024x1024 resolution, an image costs $0.0247.
ImageGPT Image 2.6 Sunburst
GPT Image 2.6 Sunburst is an image generation and editing model from OpenAI, released November 4, 2026 as part of the GPT Image 2.6 family alongside GPT Image 2.6 Flare. It takes text and image input and returns generated or edited images. OpenAI positions Sunburst for higher-quality generation and stronger consistency across edits, while Flare focuses on speed and layout quality. OpenAI says the 2.6 models generate images 50% faster than GPT Image 2.5. It is available through the OpenAI API and suits developers building campaign creative, product imagery, or multi-step editing workflows. At low quality and 1024x1024 resolution, an image costs $0.0247.
ChatGPT-6.1 Terra
GPT-6.1 Terra is a mid-tier OpenAI model that follows GPT-5.6 Terra in the Terra line. We found no official OpenAI announcement or published benchmarks for it, so details here come from the provider listing and press reports. It accepts text, image, and file input and returns text. It has a 1,050,000-token context window, 128,000 max output tokens, and supports tool calling. Pricing is $1 per million input tokens and $5 per million output tokens, lower than GPT-6.1 Sol's $2 and $10. The Information reports that OpenAI intends Terra to outperform GPT-6.1 Sol at a lower price, though we could not verify this. It suits cost-sensitive agentic and document workloads.
