What is GPT-6 Sol?
GPT-6 Sol is the middle model of OpenAI’s GPT-6 family, released on 22 September 2026 alongside GPT-6 Luna. OpenAI positions it as the faster, more affordable option below GPT-6 Astra for difficult everyday work, and says it makes about half as many factual mistakes as GPT-5.6 Sol on its internal factuality evaluation.
API pricing is $2 per million input tokens and $10 output — half GPT-5.6 Sol’s $4 / $20 — with cached input at $0.20. Per OpenAI’s developer documentation it accepts text and images, has a 1,050,000-token context window and up to 128,000 output tokens, a knowledge cutoff of 20 April 2026, and reasoning effort settings from none to max. In ChatGPT it is available in ChatGPT Work and Codex for Plus, Pro, Business, Enterprise and Edu users.

Preguntas frecuentes
How much does GPT-6 Sol cost per 1M tokens?
GPT-6 Sol costs $2.00 per 1M input tokens and $10.00 per 1M output tokens. At a typical 4:1 input-to-output mix that blends to about $3.60 per 1M tokens.
How much does GPT-6 Sol cost per month?
A small-team workload of 20M input and 5M output tokens a month costs about $90 on GPT-6 Sol. A side project (1M in / 0.25M out) costs roughly $4.50.
What is a cheaper alternative to GPT-6 Sol?
Mistral 7B is the strongest cheaper option in our database at $0.0220 per 1M blended — about 99% less than GPT-6 Sol. It is also open-weight, so self-hosting is an option.
Can I run GPT-6 Sol locally?
No. GPT-6 Sol is a closed, API-only model — the weights are not released, so it cannot be self-hosted.
Why does GPT-6 Sol charge more for output than input?
Output tokens are generated one at a time and cannot be batched the way a prompt can, so they cost the provider more to serve. GPT-6 Sol charges 5× more for output, which is why prompt-heavy workloads are far cheaper to run than generation-heavy ones.
