Our Legend tier: 500M tokens for $15/mo — 2.5× more, 1/13th the price.
"Claude Pro gives you ~10M tokens for $20/mo."
Our $1 Supporter tier gives you 15M tokens — 1.5× more for 1/20th the price.
Your tokens are yours. No surprise cutoffs.
Other providers charge $200/mo and still cut you off mid-prompt. You can't finish your thought, your refactor dies halfway, your context vanishes. We don't do that. Every token in your plan is yours to use — no invisible walls, no degraded responses, no "please upgrade" mid-conversation. You finish what you started.
That's 550× more value per dollar.
Every tier unlocks real work. Here's what your tokens actually get you.
Every request uses tokens. Bigger models use more. Here's what to expect.
| Operation | Avg tokens | On Supporter (15M) | On Legend (500M) | On Core (1B) |
|---|---|---|---|---|
| Explain a function | ~2K | 7,500× | 250,000× | 500,000× |
| Generate a component | ~5K | 3,000× | 100,000× | 200,000× |
| Refactor a file | ~10K | 1,500× | 50,000× | 100,000× |
| Long coding session (w/ context) | ~100K | 150× | 5,000× | 10,000× |
| Full codebase review | ~500K | 30× | 1,000× | 2,000× |
Heavier models cost more tokens per request. Here's what the top models cost.
