GPT-6 Astra: price, limits and messages on every plan
OpenAI's GPT-6 Astra in llmwise: how many GPT-6 Astra messages each plan gives, what counts against them, what GPT-6 Astra reads, where your messages go, and what it costs at OpenAI's API prices.
Prices and limits checked against OpenRouter's GPT-6 Astra page. Updated .
Short answer
GPT-6 Astra isn't in llmwise's free trial; it needs a paid plan. A paid plan gives up to 31 GPT-6 Astra messages a month on Pro ($20), 100 on Max ($50), 225 on Ultra ($100) and 500 on Studio ($200). Each GPT-6 Astra message's price is shown before you send it.
GPT-6 Astra on every plan
What GPT-6 Astra costs in llmwise is a count, not a token bill: up to 31 a month on Pro, and it isn't in the free trial.
| Plan | Price | GPT-6 Astra messages | Each, if all go to GPT-6 Astra |
|---|---|---|---|
| Free | $0 | Not in the trial | — |
| Pro | $20 a month | Up to 31 a month | $0.65 |
| Max | $50 a month | Up to 100 a month | $0.50 |
| Ultra | $100 a month | Up to 225 a month | $0.44 |
| Studio | $200 a month | Up to 500 a month | $0.40 |
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 Astra count is the most you get if all of it goes to GPT-6 Astra, 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 Astra usage limits, explained
Every limit on GPT-6 Astra in llmwise is published. Here's each one, in GPT-6 Astra messages.
GPT-6 Astra draws on the monthly allowance every model shares: 31 GPT-6 Astra messages on Pro if nothing else uses it. Each message on a smaller model leaves fewer GPT-6 Astra messages, each GPT-6 Astra message leaves fewer for them, and unused GPT-6 Astra messages don't carry over when the billing period renews.
Long GPT-6 Astra chats count more, because each GPT-6 Astra reply resends the whole conversation. Past 64k tokens a GPT-6 Astra reply counts as 2 messages, so Pro's 31 GPT-6 Astra messages become up to 15 such replies; past 128k it counts as 4 (up to 7 GPT-6 Astra replies); past 200k the GPT-6 Astra chat is full.
GPT-6 Astra's native context window is 1.05M tokens; llmwise stops a GPT-6 Astra chat at 200k tokens, so a GPT-6 Astra chat uses at most 200k of its 1.05M tokens.
A GPT-6 Astra reply can run to 8,000 tokens on Pro and 16,000 on Max, Ultra, and Studio, at the same GPT-6 Astra price however long it runs.
On a paid plan each web search or link read in a GPT-6 Astra reply counts as 1 more GPT-6 Astra message.
A $10 top-up adds up to 25 more GPT-6 Astra messages, valid 12 months, spent once the plan's own GPT-6 Astra count is gone.
GPT-6 Astra replies share every plan's soft cap of 100 replies an hour with the other models.

Where your GPT-6 Astra messages go
A GPT-6 Astra message goes to OpenAI directly when llmwise can reach OpenAI, or through OpenRouter when it can't.
If OpenAI fails before a GPT-6 Astra reply starts (an overload, a server error, a dropped connection), llmwise resends the GPT-6 Astra 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 Astra message can reach.
GPT-6 Astra's API price, and what a message costs
GPT-6 Astra's API price is $10.00 per million tokens in and $50.00 out: OpenAI's list price. At that price a typical GPT-6 Astra message (4,000 tokens in, 700 out) costs about $0.0750.
In llmwise a GPT-6 Astra message isn't billed by the token: it's one of up to 31 GPT-6 Astra messages a month on Pro, however long the GPT-6 Astra reply runs.
When to use GPT-6 Astra, and when a cheaper model will do
llmwise's catalog describes GPT-6 Astra as “OpenAI's flagship model”. No benchmark scores here: ask GPT-6 Astra your own question, then switch the picker to another model in the same chat, which sees GPT-6 Astra's answer too.
When a question doesn't need GPT-6 Astra, these read the same attachments, whole PDFs included, and leave more of the month for GPT-6 Astra:
GPT-6 Sol (OpenAI): up to 125 a month on Pro, against GPT-6 Astra's 31.
GPT-6 Luna (OpenAI): 60 a day on Pro, against GPT-6 Astra's 31.
Claude Opus 5.5 (Anthropic): up to 62 a month on Pro, against GPT-6 Astra's 31.
Claude Sonnet 5 (Anthropic): up to 125 a month on Pro, against GPT-6 Astra's 31.
Same count as GPT-6 Astra on every plan: Claude Fable 5.1.
