The economics of intelligence

Which AI model gives you the most brain for the money?

66 models in our dated snapshot, charted by how smart they are against what they cost: per token, per task, and what the same work would cost billed by usage.

Capability snapshot: 2026-11-01. 6 of 66 models have task measurements. OpenAI task measurements are pending.

Projected API-equivalent per week

Recorded work scaled to a full weekly meter; not measured full-week capacity.

$2,061.95–$3,436.59 · meter rounding only.

How this estimate works

20 Oct 2026 UTC sample, repriced at 4 Nov standard short-context API rates. Scaled from logged usage and a rounded meter, assuming all meter movement belongs to the logged work and the same workload remains repeatable. Outside usage and meter weighting are unverified. Not measured full-week capacity or current-plan value. Range covers rounding only.

Mixed Opus/Haiku and cache-heavy work; recovered known gap usage, but browser/cloud and other-project usage may be missing. Historical Max 20x only.

Oct 20, 2026, 01:27 UTC to Oct 20, 2026, 02:28 UTC.

Logged work priced at approximately $103.10 using the 4 November tariff. Meter: 3 → 7 (4 percentage points).

The $200.00 monthly fee is the historical test-plan assumption, not a verified invoice.

API-equivalent use is the cost of the same work at usage-based prices, not cash credits or a guaranteed allowance.

Fee shown is the historical test-plan price. API tariffs checked 2026-11-04. How we compare.

Public-data coverage: 66 model-level Epoch ECI scores; 6 Claude task cohorts. Grok task results are withheld pending source clearance. No effort-specific capability scores or current subscription allowances are verified. The private reference curves are excluded. Sources and method.

GPT-6 Astra scores highest, but GPT-6.1 Terra lands within 1 point for 10x less per token.

Claude Sonnet 5.5 lands within 2 points of Claude Opus 5.5 for half the cost per task.
