GPT-6.1 Sol vs GPT-6 Sol
GPT-6.1 Sol and GPT-6 Sol are both in llmwise. What each gets on every plan, what it reads, how it's served and what happens when its provider fails, from the catalog and the code that runs them.
Model prices and specs checked against OpenRouter's GPT-6.1 Sol page, OpenRouter's GPT-6 Sol page. Updated .
Short answer
They cost the same in llmwise: up to 125 messages a month on Pro on either. Beyond that, they read the same files and neither is easier to try. In our test runs, GPT-6.1 Sol passed 46 of the 50 prompts both answered and GPT-6 Sol 45; 3 prompts split them, most on summarization (5 to 4).
GPT-6.1 Sol vs GPT-6 Sol, prompt by prompt
Every prompt GPT-6.1 Sol and GPT-6 Sol both answered, compared directly, their biggest differences first. One run each, through OpenRouter: a wait depends on the provider and the load that day, so a lead under 10% counts as close.
Of the 50 prompts both answered, both passed 44, only GPT-6.1 Sol passed 2, only GPT-6 Sol passed 1, and neither passed 3. GPT-6.1 Sol answered sooner on 19 of the 50 and GPT-6 Sol on 16; the rest were within 10% of each other. The 50 replies cost $0.0597 on GPT-6.1 Sol and $0.1297 on GPT-6 Sol: 2.2× less on GPT-6.1 Sol.
The 3 prompts only one of GPT-6.1 Sol and GPT-6 Sol passed
An article in three bullets (summarization): GPT-6.1 Sol passed and GPT-6 Sol didn't. GPT-6.1 Sol: Graded 4.7 of 5 on average (lowest 4). GPT-6 Sol: Graded 4.0 of 5 on average (lowest 3); but 66 words, over the 60 allowed.
A refund request outside the window (customer support): GPT-6 Sol passed and GPT-6.1 Sol didn't. GPT-6.1 Sol: Graded 3.7 of 5 on average (lowest 3). GPT-6 Sol: Graded 4.3 of 5 on average (lowest 4).
Idioms into natural Japanese (translation): GPT-6.1 Sol passed and GPT-6 Sol didn't. GPT-6.1 Sol: Back-translation chrF 0.44 (pass at 0.4). GPT-6 Sol: Back-translation chrF 0.40 (pass at 0.4); reads back too far from the original.

GPT-6.1 Sol and GPT-6 Sol on every plan
Whether the one-time free trial reaches each model, then each paid plan's messages on it.
| Plan | Price | GPT-6.1 Sol | GPT-6 Sol |
|---|---|---|---|
| Free | $0 | In the one-time trial of 5 messages | In the one-time trial of 5 messages |
| Pro | $20 a month | Up to 125 a month | Up to 125 a month |
| Max | $50 a month | Up to 400 a month | Up to 400 a month |
| Ultra | $100 a month | Up to 900 a month | Up to 900 a month |
| Studio | $200 a month | Up to 2,000 a month | Up to 2,000 a month |
Prices don't include tax, which is added where it applies and shown before you pay. A paid plan's month is one allowance shared by every model, so each monthly count is the most you get if all of it goes to that model. It renews each billing period; everyday models refill daily at 00:00 UTC. Long chats count more per reply. 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.
What differs
Messages on Pro
They cost the same in llmwise: up to 125 messages a month on Pro on either.
Context window
Both take up to 1.05M tokens of context. A chat in llmwise holds up to 200k tokens, which fits in either, so the difference shows only through each maker's own API.
Images and PDFs
Both read images. Both take a PDF as the whole file, pages and all.
On Free
Both are in the free trial.
Where messages go
Both are GPT models, served the same way. Sent to OpenAI directly.
