  1. 1
    Intelligence Score—

    50% AA agentic + 40% AA coding + 10% AA speed.

  2. 2
    Estimated monthly tokens6M

    Normalized from the plan's observed usage limits — an estimate, not a guarantee.

  3. 3
    Model-adjusted tokens—

    Tokens scaled for the model's relative efficiency.

  4. 4
    Intelligence-adjusted capacity—

    Tokens × (Intelligence Score / 100).

  5. 5
    Per dollar$20/mo

    Intelligence-adjusted capacity ÷ monthly price = raw value.

  6. 6
    Raw value—

    Intelligence-adjusted capacity per dollar before normalization.

  7. 7
    Normalized Value per Intelligence per Task—

    Scaled to 0–100 against a reference of 1M quality-adjusted tokens at $20/mo.

Caveats
  • •No AA data available
  • •No cost-per-task data — efficiency neutral
