How to compare
Add models to the comparison dock
From the result grid, click the Compare button on any model card. A floating dock appears at the bottom of the page showing the selected models as chips —
claude-3-7-sonnet, claude-opus-4-6, gemini-2.5-flash-lite, etc.You can add up to 3 models per comparison. Remove one by clicking the × on its chip.Open the comparison view
Click the orange Compare button in the dock. A full-screen modal opens with every model’s specs in aligned columns.
Review side-by-side
The modal compares each model across every attribute that matters when choosing one:
- Provider and Model ID
- Billing Type (pay-as-you-go vs. flat)
- Input Price and Output Price per 1M tokens
- Flat Price (for media models)
- Context Window (in tokens)
- Endpoint (e.g.,
/v1/chat/completions) - Capabilities + sub-capabilities
- Cost estimates for three request sizes: 1K in + 1K out, 10K in + 2K out, 100K in + 10K out
Share the comparison
Three share options appear at the top of the modal:
- Share Link — copies a URL (e.g.,
aisa.one/models?compare=13,20,27). Anyone who opens it lands on the same comparison. - Copy as Image — renders the comparison as a PNG for dropping into Slack, decks, or docs.
- Twitter — posts the comparison card straight to X.
