GPT-6.1 Sol pricing: API price, cost per message and plans
What GPT-6.1 Sol costs, three ways: OpenAI's API price per token, what GPT-6.1 Sol's replies actually cost in our test runs, and how many GPT-6.1 Sol messages each llmwise plan includes. Every limit on GPT-6.1 Sol is on its model page.
API prices checked against OpenRouter's GPT-6.1 Sol page. Updated .
Short answer
GPT-6.1 Sol's API price is $2.00 per million input tokens and $10.00 per million output tokens (OpenAI's list price, September 2026). In our 50 test runs a GPT-6.1 Sol reply cost $0.0012 on average (median $0.0010), from $0.00073 a reply on agents and tool use to $0.0023 on coding. In llmwise you pay per message instead: up to 125 GPT-6.1 Sol messages a month on Pro ($20), 400 on Max ($50), 900 on Ultra ($100) and 2,000 on Studio ($200).

Across all 50 GPT-6.1 Sol replies: $0.0012 on average, $0.0010 at the median, $0.00059 for the cheapest and $0.0038 for the dearest. The GPT-6.1 Sol replies averaged 495 tokens in and 140 out, against the typical message's 4,000 in and 700 out: each test prompt starts a new chat, while a reply deep in a long chat rereads all of it.
GPT-6.1 Sol on each llmwise plan
In llmwise a GPT-6.1 Sol message is one of a published count, however long the reply runs, and you see what's left before you send.
Free: GPT-6.1 Sol is in the one-time trial of 5 messages, no card needed.
Pro, $20 a month: up to 125 GPT-6.1 Sol messages a month, which is $0.16 a GPT-6.1 Sol message if every message goes to GPT-6.1 Sol.
Max, $50 a month: up to 400 GPT-6.1 Sol messages a month, which is $0.13 a GPT-6.1 Sol message if every message goes to GPT-6.1 Sol.
Ultra, $100 a month: up to 900 GPT-6.1 Sol messages a month, which is $0.11 a GPT-6.1 Sol message if every message goes to GPT-6.1 Sol.
Studio, $200 a month: up to 2,000 GPT-6.1 Sol messages a month, which is $0.10 a GPT-6.1 Sol message if every message goes to GPT-6.1 Sol.
A $10 top-up adds up to 100 GPT-6.1 Sol messages, valid 12 months.
Every limit is published. Paid plans also have a monthly fair-use limit on AI cost: Pro $7.50, Max $20, Ultra $42, Studio $85. Using every message on your plan at typical sizes stays under it; very large messages and heavy research use it faster. Every limit, explained.
