SWE-2 pricing: real cost per million tokens

What Cognition's SWE-2 really costs across 1 plan from 1 provider: monthly fees, usable allowances and real per-token prices, against the official API list price and independent leaderboards.

Data updated · How real prices are computed

As of 2026-10-08, SWE-2 is unmetered on every channel we track (real cost ≈$0).

SWE-2 plans and real prices

Real price = monthly fee ÷ tokens you can actually use in a month. “vs API” shows how many times cheaper than the official API list price (standard workload mix) the plan is. “Evidence” opens the full calculation and sources for that row.

Behind each number

For every plan: the data date, the exact calculation, the quota basis, how leaderboard scores were mapped, and the original adoption evidence with its sources.

Adoption evidence · source and rationale (translated from the Chinese record)

Official post 2026-09-10: SWE-2 free for all Pro, Max & Teams subscribers for the next month; in the maintainer's panel the same-segment swe-2 45.5M tokens drew no quota; docs.devin.ai/admin/billing/usage shows no concurrency cap; devin-swe2-round1-2026-09-12.json

Added ≈$0/MTok (recorded as 0): during the SWE-2 promo it draws no quota and is not billed for Pro/Max/Teams, with no concurrency cap → unbounded denominator; the ruled it enters the frontier at the promo price and changes the frontier, ending 2026-10-31 (specified; the official post says only 'for the next month'); the cheapest available tier Pro $20 is used — Max has the same Y, is pricier, and is not drawn twice; after the promo ends the billing weight must be re-checked — the pricing page's permanent-free basis is SWE 1.7, not SWE-2
