GPT-6 Sol: price, limits and messages on every plan
OpenAI's GPT-6 Sol in llmwise: how many GPT-6 Sol messages each plan gives, what counts against them, what GPT-6 Sol reads, where your messages go, and what it costs at OpenAI's API prices.
Prices and limits checked against OpenRouter's GPT-6 Sol page. Updated .
Short answer
GPT-6 Sol isn't in llmwise's free trial; it needs a paid plan. A paid plan gives up to 62 GPT-6 Sol messages a month on Plus ($10), 125 on Pro ($20), 400 on Max ($50), 900 on Ultra ($100) and 2,000 on Studio ($200). Each GPT-6 Sol message's price is shown before you send it.
In the news: GPT-6 Sol and Luna are out: half the API price, and what they cost you ().
What OpenAI announced, sourced on its launch page:
- OpenAI trained Sol and Luna with methods like those behind GPT-6 Astra, which it released earlier in September and still calls its best model across the board.
- Sol went from $4 to $2 per million input tokens and from $20 to $10 per million output; Luna from $0.20 to $0.10 in and from $1.20 to $0.50 out. OpenAI calls that 50% cheaper than the previous generation's promotional prices.
- Sol's context window is 1,050,000 tokens and a reply can run to 128,000 tokens; prompts over 272K input tokens are billed at twice the input rate and 1.5 times the output rate.
GPT-6 Sol on every plan
What GPT-6 Sol costs in llmwise is a count, not a token bill: up to 125 a month on Pro, and it isn't in the free trial.
| Plan | Price | GPT-6 Sol messages | Each, if all go to GPT-6 Sol |
|---|---|---|---|
| Free | $0 | Not in the trial | — |
| Plus | $10 a month | Up to 62 a month | $0.16 |
| 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 Sol count is the most you get if all of it goes to GPT-6 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: Plus $3.75, 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 Sol usage limits, explained
Every limit on GPT-6 Sol in llmwise is published. Here's each one, in GPT-6 Sol messages.
GPT-6 Sol draws on the monthly allowance every model shares: 125 GPT-6 Sol messages on Pro if nothing else uses it. Each message on a smaller model leaves fewer GPT-6 Sol messages, each GPT-6 Sol message leaves fewer for them, and unused GPT-6 Sol messages don't carry over when the billing period renews.
Long GPT-6 Sol chats count more, because each GPT-6 Sol reply resends the whole conversation. Past 64k tokens a GPT-6 Sol reply counts as 2 messages, so Pro's 125 GPT-6 Sol messages become up to 62 such replies; past 128k it counts as 4 (up to 31 GPT-6 Sol replies); past 200k the GPT-6 Sol chat is full.
GPT-6 Sol's native context window is 1.05M tokens; llmwise stops a GPT-6 Sol chat at 200k tokens, so a GPT-6 Sol chat uses at most 200k of its 1.05M tokens.
A GPT-6 Sol reply can run to 8,000 tokens on Plus and Pro and 16,000 on Max, Ultra, and Studio, at the same GPT-6 Sol price however long it runs.
On a paid plan each web search or link read in a GPT-6 Sol reply counts as 1 more GPT-6 Sol message.
A $10 top-up adds up to 100 more GPT-6 Sol messages, valid 12 months, spent once the plan's own GPT-6 Sol count is gone.
GPT-6 Sol replies share every plan's soft cap of 100 replies an hour with the other models.

Where your GPT-6 Sol messages go
A GPT-6 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 Sol reply starts (an overload, a server error, a dropped connection), llmwise resends the GPT-6 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 Sol message can reach.
GPT-6 Sol's API price, and what a message costs
GPT-6 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 Sol message (4,000 tokens in, 700 out) costs about $0.0150.
In llmwise a GPT-6 Sol message isn't billed by the token: it's one of up to 125 GPT-6 Sol messages a month on Pro, however long the GPT-6 Sol reply runs.

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

How GPT-6 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’re happy to share that Crumb & Co. is opening a second shop in Leeds on 14 November. When we opened our first bakery, we hoped to make good bread and bakes for our neighbours. The support we’ve had since then has meant more than we can say. Opening another shop is a big step for our small team, and we’re grateful to everyone who has helped us get here. If you’re in Leeds on opening day, please stop by and say hello. Coffee is on us all day, and we’d love to welcome you into the new space. Thank you for making room for Crumb & Co. in your routine. We can’t wait to meet more of our neighbours.
Questions
Is GPT-6 Sol free in llmwise?
No. GPT-6 Sol isn't in llmwise's free trial, which is Claude Haiku 5.5 alone. Pro ($20 a month) gets up to 125 GPT-6 Sol messages a month.
What are GPT-6 Sol's usage limits in llmwise?
GPT-6 Sol has a published monthly count on each paid plan (up to 125 GPT-6 Sol messages a month on Pro), shared with the other models. A long GPT-6 Sol chat counts each reply as 2 GPT-6 Sol messages past 64k tokens and 4 past 128k.
What happens when my GPT-6 Sol messages run out?
Your GPT-6 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 Sol messages.
How much context does GPT-6 Sol have in llmwise?
1.05M tokens is GPT-6 Sol's native context window. A GPT-6 Sol chat in llmwise stops at 200k tokens, and past 64k each GPT-6 Sol reply counts as more than one message, so a new GPT-6 Sol chat for each new task goes further.
