description: Report cumulative GAIA API spend and project cost for planned configurations
argument-hint: "[--level=1] [--limit=53] [--models=haiku,sonnet] [--voting=1]"

/gaia cost

Show cumulative API spend across all stored GAIA runs and project the cost for a planned configuration before you commit to running it.

Usage

/gaia cost
/gaia cost --level=1 --limit=53 --models=claude-sonnet-4-6
/gaia cost --level=1 --limit=300 --models=sonnet,haiku --voting=3

Options

| Flag | Default | Description | |------|---------|-------------| | `--level` | `1` | Level for projection | | `--limit` | `53` | Number of questions for projection | | `--models` | `claude-haiku-4-5` | Comma-separated models for projection | | `--voting` | `1` | Self-consistency attempts multiplier | | `--hardness-routing` | off | Include hardness-router model-mix estimate |

Pricing reference

| Model | Input ($/M tokens) | Output ($/M tokens) | |-------|--------------------|---------------------| | claude-haiku-4-5 | $0.25 | $1.25 | | claude-sonnet-4-6 | $3.00 | $15.00 | | claude-opus-4-5 | $15.00 | $75.00 |

Estimates assume 1,500 input tokens / turn and 512 output tokens / turn, 4.2 mean turns per question (measured baseline).

Example output

Cumulative spend (all stored runs)
------------------------------------
Total runs:    3
Total Q's:    159
Total spend:  $0.97
  Haiku:      $0.09  (53 Q × 1 attempt)
  Sonnet:     $0.88  (106 Q × 1 attempt)

Projection for: L1, 53 Q, sonnet × 3 voting
----------------------------------------------
Questions:        53
Attempts/Q:        3
Effective Q's:   159
Est. input tok:  238,500
Est. output tok:  81,600
Est. cost:        $1.94

  Above $5 threshold: NO — proceed without confirmation

Cost confirmation gate

When a projected run exceeds $5, the `/gaia run` command will display this cost estimate and require explicit confirmation before proceeding.

Steps Claude should follow

1. Load history: `npx @claude-flow/cli@latest memory list --namespace gaia-runs` 2. Sum `est_cost_usd` across all stored runs to produce cumulative spend. 3. Compute projection for the requested configuration:

• `effective_questions = limit × voting`
• Per question: assume 4.2 turns (measured), 1500 input tokens/turn, 512 output tokens/turn
• Multiply by model pricing

4. Display the cumulative table and the projection side by side. 5. Flag with a warning banner if projected cost exceeds $5.
