GPT-6.1 Sol: price, limits and messages on every plan
OpenAI's GPT-6.1 Sol in llmwise: how many GPT-6.1 Sol messages each plan gives, what counts against them, what GPT-6.1 Sol reads, where your messages go, and what it costs at OpenAI's API prices.
Prices and limits checked against OpenRouter's GPT-6.1 Sol page. Updated .
Short answer
GPT-6.1 Sol is in llmwise's one-time free trial of 5 messages. A paid plan gives 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). Each GPT-6.1 Sol message's price is shown before you send it.
In the news: OpenAI DevDay 2026: GPT-6.1 Sol and what else OpenAI announced ().
What OpenAI announced, sourced on its launch page:
- OpenAI calls DevDay 2026 its biggest yet, with more than 20 major announcements across ChatGPT, Codex, its models and new ways of working with AI.
- OpenAI says GPT-6.1 Sol nearly matches GPT-6 Astra on agentic coding, computer use and professional work, at one-fifth of Astra's standard input and output token prices.
- GPT-6.1 Sol's standard API prices are $2 per million input tokens, $0.10 per million cached input tokens and $10 per million output tokens; in OpenAI's API it's gpt-6.1-sol.
GPT-6.1 Sol on every plan
What GPT-6.1 Sol costs in llmwise is a count, not a token bill: up to 125 a month on Pro, and it's one of the models in the 5-message free trial.
| Plan | Price | GPT-6.1 Sol messages | Each, if all go to GPT-6.1 Sol |
|---|---|---|---|
| Free | $0 | In the one-time trial of 5 messages | — |
| Pro | $20 a month | Up to 125 a month | $0.16 |
| Max | $50 a month | Up to 400 a month | $0.13 |
| Ultra | $100 a month | Up to 900 a month | $0.11 |
| Studio | $200 a month | Up to 2,000 a month | $0.10 |
Prices don't include tax, which is added where it applies and shown before you pay. A paid plan's month is one allowance every model shares, so each GPT-6.1 Sol count is the most you get if all of it goes to GPT-6.1 Sol, and "each" is the plan's price divided by that count. How pricing works.
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.
GPT-6.1 Sol usage limits, explained
Every limit on GPT-6.1 Sol in llmwise is published. Here's each one, in GPT-6.1 Sol messages.
GPT-6.1 Sol draws on the monthly allowance every model shares: 125 GPT-6.1 Sol messages on Pro if nothing else uses it. Each message on a smaller model leaves fewer GPT-6.1 Sol messages, each GPT-6.1 Sol message leaves fewer for them, and unused GPT-6.1 Sol messages don't carry over when the billing period renews.
Long GPT-6.1 Sol chats count more, because each GPT-6.1 Sol reply resends the whole conversation. Past 64k tokens a GPT-6.1 Sol reply counts as 2 messages, so Pro's 125 GPT-6.1 Sol messages become up to 62 such replies; past 128k it counts as 4 (up to 31 GPT-6.1 Sol replies); past 200k the GPT-6.1 Sol chat is full.
GPT-6.1 Sol's native context window is 1.05M tokens; llmwise stops a GPT-6.1 Sol chat at 200k tokens, so a GPT-6.1 Sol chat uses at most 200k of its 1.05M tokens.
A GPT-6.1 Sol reply can run to 8,000 tokens on Pro and 16,000 on Max, Ultra, and Studio, at the same GPT-6.1 Sol price however long it runs.
On a paid plan each web search or link read in a GPT-6.1 Sol reply counts as 1 more GPT-6.1 Sol message.
A $10 top-up adds up to 100 more GPT-6.1 Sol messages, valid 12 months, spent once the plan's own GPT-6.1 Sol count is gone.
GPT-6.1 Sol replies share every plan's soft cap of 100 replies an hour with the other models.

Where your GPT-6.1 Sol messages go
A GPT-6.1 Sol message goes to OpenAI directly when llmwise can reach OpenAI, or through OpenRouter when it can't.
If OpenAI fails before a GPT-6.1 Sol reply starts (an overload, a server error, a dropped connection), llmwise resends the GPT-6.1 Sol request through OpenRouter, to endpoints that, according to OpenRouter, don't store prompts for their own use or train on them.
The Privacy Policy lists every company a GPT-6.1 Sol message can reach.
GPT-6.1 Sol's API price, and what a message costs
GPT-6.1 Sol's API price is $2.00 per million tokens in and $10.00 out: OpenAI's list price. At that price a typical GPT-6.1 Sol message (4,000 tokens in, 700 out) costs about $0.0150.
In llmwise a GPT-6.1 Sol message isn't billed by the token: it's one of up to 125 GPT-6.1 Sol messages a month on Pro, however long the GPT-6.1 Sol reply runs.

When to use GPT-6.1 Sol, and when a cheaper model will do
llmwise's catalog describes GPT-6.1 Sol as “Newest Sol, near-Astra for coding and agentic work”. No benchmark scores here: ask GPT-6.1 Sol your own question, then switch the picker to another model in the same chat, which sees GPT-6.1 Sol's answer too.
When a question doesn't need GPT-6.1 Sol, these read the same attachments, whole PDFs included, and leave more of the month for GPT-6.1 Sol:
GPT-6 Luna (OpenAI): 60 a day on Pro, against GPT-6.1 Sol's 125.
Claude Haiku 4.5 (Anthropic): up to 250 a month on Pro, against GPT-6.1 Sol's 125.
Gemini 3.8 Flash (Google): up to 250 a month on Pro, against GPT-6.1 Sol's 125.
Grok 4.7 (xAI): up to 250 a month on Pro, against GPT-6.1 Sol's 125.
Same count as GPT-6.1 Sol on every plan: Claude Sonnet 5.5, Claude Sonnet 5, GPT-6 Sol, Gemini 3.1 Pro and Kimi K3.

How GPT-6.1 Sol began its reply to our first writing prompt, “Write a LinkedIn post of 100 to 150 words announcing that our small bakery, Crumb & Co., opens a second shop in Leeds on 14 November. Mention the free coffee…”:
We’ve got some lovely news to share: Crumb & Co. is opening a second shop in Leeds on 14 November. As a small bakery, this is a big step for us, and we’re grateful to everyone who has helped us get here. Every visit, kind word and recommendation has meant a lot. We’re looking forward to welcoming familiar faces and meeting new neighbours, with the same care and love for baking that we bring to our first shop. To celebrate, we’ll be offering free coffee on opening day. Come in, say hello and help us mark the start of this next chapter. We can’t wait to welcome you. See you on 14 November!
Questions
Is GPT-6.1 Sol free in llmwise?
GPT-6.1 Sol is in llmwise's one-time free trial of 5 messages, with no card. After that it needs a paid plan: Pro ($20 a month) gets up to 125 GPT-6.1 Sol messages a month.
What are GPT-6.1 Sol's usage limits in llmwise?
GPT-6.1 Sol has a published monthly count on each paid plan (up to 125 GPT-6.1 Sol messages a month on Pro), shared with the other models. A long GPT-6.1 Sol chat counts each reply as 2 GPT-6.1 Sol messages past 64k tokens and 4 past 128k.
What happens when my GPT-6.1 Sol messages run out?
Your GPT-6.1 Sol count resets when your billing period renews. Until then, the everyday models keep answering on their own daily count, and a $10 top-up adds up to 100 more GPT-6.1 Sol messages.
How much context does GPT-6.1 Sol have in llmwise?
1.05M tokens is GPT-6.1 Sol's native context window. A GPT-6.1 Sol chat in llmwise stops at 200k tokens, and past 64k each GPT-6.1 Sol reply counts as more than one message, so a new GPT-6.1 Sol chat for each new task goes further.
