Devin SWE-2 free window ends mid-Oct: budget the $3/$15 meter

What happened

What happened (verified 2026-10-11 on Cognition docs): SWE-2 stays free for self-serve Devin Desktop/CLI plans through October 15, 2026 (docs). Marketing/pricing copy still says through October 16. After the free window, list rates apply: $3.00/1M input, $15.00/1M output, $0.30/1M cache input. Enterprise ACU plans keep SWE-2 at 75% off list through December 31, 2026 — that discount does not apply to self-serve seats. Voice-mode live calls use a separate agent model and do not get free or discounted SWE-2. Tool impact: teams treating SWE-2 as an unlimited free frontier habit will feel a sudden agent-meter cliff on top of Pro ($20) / Max ($200) / Teams seats; Windsurf→Devin Desktop rename and Cascade→Devin Local already stand.

Switch or not?

Try: if Devin Desktop/CLI is already your primary agent surface and SWE-2 is your default, burn the free window on real multi-file tickets this week (budget Oct 15 docs / Oct 16 marketing). Measure tokens + finished PRs so you know what list rates will cost. Avoid: adding Devin as a third seat beside Cursor + Copilot just to "use the free SWE-2" — the free window ends mid-Oct and the $3/$15 list meter is not a free forever seat. Don't assume Enterprise ACU 75% off through Dec 31 applies to self-serve. Next: (1) budget as if Oct 15; (2) after the cliff, stay on cheaper models inside quota, pay list on SWE-2, or keep one primary agent elsewhere; (3) re-verify https://docs.devin.ai/desktop/models and https://devin.ai/pricing before you renew. last-verified 2026-10-12.

Money / risk

Date mismatch is material: docs end free self-serve on Oct 15; pricing marketing often says Oct 16 — budget the earlier day. Post-cliff SWE-2 list ($3/$15/$0.30 cache) turns unlimited free frontier habits into a metered agent bill on top of seats. Voice live calls never get the free/discounted SWE-2 promo. Enterprise 75% off through Dec 31 is ACU-only — self-serve buyers who assume that discount over-budget.
