🧮 How your tokens are used

Your balance works across all available models.

Each model has its own multiplier. The number of tokens actually available depends on which model you use.

If the full 1,000,000-token balance is used on one model:

* ×2.5 — GPT-5.6 Luna → 400,000 tokens
* ×4 — Claude Sonnet 4.6 → 250,000 tokens
* ×5 — Claude Sonnet 5 → 200,000 tokens
* ×6 — GPT-5.6 Terra → ~166,666 tokens
* ×8 — GPT-5.6 Sol → 125,000 tokens
* ×10 — Claude Opus 5 → 100,000 tokens
* ×16 — GPT-6 Astra → 62,500 tokens
* ×20 — Claude Fable 5.1 → 50,000 tokens

If the full 5,000,000-token balance is used on one model:

* ×2.5 — GPT-5.6 Luna → 2,000,000 tokens
* ×4 — Claude Sonnet 4.6 → 1,250,000 tokens
* ×5 — Claude Sonnet 5 → 1,000,000 tokens
* ×6 — GPT-5.6 Terra → ~833,333 tokens
* ×8 — GPT-5.6 Sol → 625,000 tokens
* ×10 — Claude Opus 5 → 500,000 tokens
* ×16 — GPT-6 Astra → 312,500 tokens
* ×20 — Claude Fable 5.1 → 250,000 tokens

Lower-multiplier models make your balance last longer. Higher-end models consume the balance faster.
