GPT-6 Luna: price, limits and messages on every plan
OpenAI's GPT-6 Luna in llmwise: how many GPT-6 Luna messages each plan gives, what counts against them, what GPT-6 Luna reads, where your messages go, and what it costs at OpenAI's API prices.
Prices and limits checked against OpenRouter's GPT-6 Luna page. Updated .
Short answer
GPT-6 Luna isn't in llmwise's free trial; it needs a paid plan. As an everyday model it has a daily count: 30 GPT-6 Luna messages a day on Plus ($10), 60 on Pro ($20), 120 on Max ($50), 200 on Ultra ($100) and 200 on Studio ($200), refilled every day at 00:00 UTC. Each GPT-6 Luna message's price is shown before you send it.
In the news: OpenAI DevDay 2026: GPT-6.1 Sol and what else OpenAI announced (); 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 Luna on every plan
What GPT-6 Luna costs in llmwise is a count, not a token bill: 60 a day on Pro, and it isn't in the free trial.
| Plan | Price | GPT-6 Luna messages |
|---|---|---|
| Free | $0 | Not in the trial |
| Plus | $10 a month | 30 a day |
| Pro | $20 a month | 60 a day |
| Max | $50 a month | 120 a day |
| Ultra | $100 a month | 200 a day |
| Studio | $200 a month | 200 a day |
Prices don't include tax, which is added where it applies and shown before you pay. GPT-6 Luna is an everyday model: its count is a day's, refilled at 00:00 UTC, and it doesn't touch the monthly allowance the other models share. 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 Luna usage limits, explained
Every limit on GPT-6 Luna in llmwise is published. Here's each one, in GPT-6 Luna messages.
GPT-6 Luna has a daily count on every paid plan: 30 GPT-6 Luna messages on Plus, 60 GPT-6 Luna messages on Pro, 120 GPT-6 Luna messages on Max, 200 GPT-6 Luna messages on Ultra, 200 GPT-6 Luna messages on Studio. The GPT-6 Luna count refills at 00:00 UTC, and yesterday's unused GPT-6 Luna messages don't carry over.
Long GPT-6 Luna chats count more, because each GPT-6 Luna reply resends the whole conversation. Past 64k tokens a GPT-6 Luna reply counts as 2 messages, so Pro's 60 GPT-6 Luna messages become up to 30 such replies; past 128k it counts as 4 (up to 15 GPT-6 Luna replies); past 200k the GPT-6 Luna chat is full.
GPT-6 Luna's native context window is 1.05M tokens; llmwise stops a GPT-6 Luna chat at 200k tokens, so a GPT-6 Luna chat uses at most 200k of its 1.05M tokens.
A GPT-6 Luna reply can run to 8,000 tokens on Plus and Pro and 16,000 on Max, Ultra, and Studio, at the same GPT-6 Luna price however long it runs.
On a paid plan each web search or link read in a GPT-6 Luna reply counts as 1 Claude Haiku 4.5 message.
A $10 top-up adds to the monthly allowance, not to GPT-6 Luna's daily count of 60 on Pro.
GPT-6 Luna replies share every plan's soft cap of 100 replies an hour with the other models.

Where your GPT-6 Luna messages go
A GPT-6 Luna message goes to OpenAI directly when llmwise can reach OpenAI, or through OpenRouter when it can't.
If OpenAI fails before a GPT-6 Luna reply starts (an overload, a server error, a dropped connection), llmwise resends the GPT-6 Luna 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 Luna message can reach.
GPT-6 Luna's API price, and what a message costs
GPT-6 Luna's API price is $0.10 per million tokens in and $0.50 out: OpenAI's list price. At that price a typical GPT-6 Luna message (4,000 tokens in, 700 out) costs about $0.0008.
In llmwise a GPT-6 Luna message isn't billed by the token: it's one of 60 GPT-6 Luna messages a day on Pro, however long the GPT-6 Luna reply runs.

When to use GPT-6 Luna, and when a cheaper model will do
llmwise's catalog describes GPT-6 Luna as “Small, fast, and inexpensive”. No benchmark scores here: ask GPT-6 Luna your own question, then switch the picker to another model in the same chat, which sees GPT-6 Luna's answer too.
GPT-6 Luna is an everyday model, so nothing in llmwise costs less: its 60 messages a day on Pro come on top of the monthly allowance.
Same count as GPT-6 Luna on every plan: Claude Haiku 5.5, DeepSeek V4.1 Flash and GLM 5.3 Flash.

How GPT-6 Luna 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 delighted to share that Crumb & Co. is opening a second shop in Leeds on 14 November! What began as one small bakery has grown thanks to the lovely people who’ve stopped by, shared a loaf, and made us feel part of the community. We’re excited to bring our freshly baked bread, pastries, and warm welcomes to a new neighbourhood. To celebrate opening day, we’ll be giving away free coffee. Pop in, say hello, and enjoy a cup with us—we’d love to meet you. Thank you to everyone who has supported Crumb & Co. so far. We can’t wait to open the doors and start this next chapter together. See you in Leeds on 14 November!
Questions
Is GPT-6 Luna free in llmwise?
No. GPT-6 Luna isn't in llmwise's free trial, which is Claude Haiku 5.5 alone. Pro ($20 a month) gets 60 GPT-6 Luna messages a day.
What are GPT-6 Luna's usage limits in llmwise?
GPT-6 Luna has a published daily count on each paid plan (60 GPT-6 Luna messages a day on Pro), refilled at 00:00 UTC. A long GPT-6 Luna chat counts each reply as 2 GPT-6 Luna messages past 64k tokens and 4 past 128k.
What happens when my GPT-6 Luna messages run out?
Your 60 GPT-6 Luna messages come back at 00:00 UTC. Until then, the models on the monthly allowance keep answering.
How much context does GPT-6 Luna have in llmwise?
1.05M tokens is GPT-6 Luna's native context window. A GPT-6 Luna chat in llmwise stops at 200k tokens, and past 64k each GPT-6 Luna reply counts as more than one message, so a new GPT-6 Luna chat for each new task goes further.
