A hard prompt: “Argue both sides of free buses”, in full.
GPT-6 Sol
Passed: Graded 4.3 of 5 on average (lowest 4).
A city should make its buses free because a fare can keep people from jobs, classes, and medical appointments. Removing it would make every trip easier, especially for residents with the least money. Boarding would be faster without payment, and some drivers might leave their cars at home, easing traffic and pollution. Funding buses through taxes treats mobility as a public service: everyone benefits when more people can reach what they need. But free fares are not free service. Fare revenue helps pay for frequent, reliable buses; lose it without secure replacement funding, and riders may face longer waits and crowded routes. Even with new taxes, a city could spend that money on more drivers and better coverage instead. A zero-dollar fare does little for someone whose bus rarely comes. Targeted discounts for low-income riders would protect access while preserving resources to make the service worth taking.

Grok 4.7
Failed: Graded 4.7 of 5 on average (lowest 4); but a paragraph of 100 words, over the 90 allowed.
A city should make its buses free because fare collection costs money, slows boarding, and keeps poorer riders off the system. Zero fares would cut those overheads, fill empty seats, and turn transit into a genuine public service rather than a paywall. Riders who switch from cars would ease congestion and pollution, while workers, students, and elderly residents would gain reliable mobility without budgeting for every trip. The social return—fewer missed shifts, wider access to jobs and clinics, a more livable street—outweighs the lost ticket revenue if the city funds the gap from parking fees or a modest local tax. Free buses fail when they are treated as a gift rather than a service that must still run on time. Without fares, demand surges while revenue collapses, so agencies cut frequency, defer maintenance, and pack vehicles until riding becomes slower and less safe than driving. Crowding and disorder drive away the very commuters whose fares once subsidized off-peak routes, and taxpayers who never ride absorb a growing bill with no accountability for performance. A cheap fare, paired with faster boarding and more buses, keeps the system solvent and trustworthy; abolishing the price does not create capacity, and a free bus that does not come is worthless.

GPT-6 Sol and Grok 4.7 on every plan
Whether the one-time free trial reaches each model, then each paid plan's messages on it.
| Plan | Price | GPT-6 Sol | Grok 4.7 |
|---|---|---|---|
| Free | $0 | Not in the trial | Not in the trial |
| Plus | $10 a month | Up to 62 a month | Up to 125 a month |
| Pro | $20 a month | Up to 125 a month | Up to 250 a month |
| Max | $50 a month | Up to 400 a month | Up to 800 a month |
| Ultra | $100 a month | Up to 900 a month | Up to 1,800 a month |
| Studio | $200 a month | Up to 2,000 a month | Up to 4,000 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: 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.
What differs
Messages on Pro
Grok 4.7 gets twice as many messages: up to 250 messages a month on Pro, against up to 125 messages a month for GPT-6 Sol.
Context window
GPT-6 Sol takes up to 1.05M tokens; Grok 4.7 up to 500K tokens. 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
Neither is in the free trial: both need a paid plan, from Plus.
Where messages go
GPT-6 Sol: Sent to OpenAI directly. Grok 4.7: Served through OpenRouter by xAI alone, on an endpoint that doesn't store or train on prompts.
