BC-0719-1: Cowork/Code: tier lineup renamed — Free / Pro / Max / Ultra, Ultra price reduced

Old format supported until: 18.07.2026

Before

The tier field in GET /v1/cowork/state and GET /v1/cowork/me responses (as well as recommendation.upgrade.nextTier and the tiers[] catalog) took the values FREE, START, PRO, MAX. The MAX tier (×20) cost 40,000 Ꝟ/mo.

After

The lineup is renamed with a shift: START → PRO, PRO → MAX, MAX → ULTRA; the value set is now FREE, PRO, MAX, ULTRA. Tier multipliers are unchanged: PRO ×1 (base), MAX ×5, ULTRA ×20; FREE is 5% of PRO. The ULTRA price (former MAX, ×20 volume) dropped from 40,000 to 20,000 Ꝟ/mo. Window volumes were recalibrated against real usage: the five-hour window doubled on every tier while monthly volumes were reduced; limits of an already-paid period do not change — the new values apply from the next renewal. The rename applies atomically at release time: the START value is no longer returned, and the ULTRA value was added. Clients branching on the string values of tier / nextTier must update their mapping and mind the meaning shift (PRO is now the base tier, MAX the middle one); clients that render the server-provided multiplier / feeVibes as-is keep working unchanged.

FIX-0719-2: Cowork/Code tier prices on the international version now use the dollar scale

Before

On the international version the tier catalog in GET /v1/cowork/state returned prices on the Russian-version scale: feeVibes 2000 / 10000 / 20000 for Pro / Max / Ultra. At 1 Vibe credit = 1 US dollar this read as 2000–20000 dollars per month.

After

The tier catalog on the international version returns the dollar grid: Pro — feeVibes: 20, Max — 100, Ultra — 200 per month; the three quota windows are scaled consistently, so tier capacity in requests is unchanged. The Russian version is not affected.

Impact on integrators

If your client reads tiers[].feeVibes from GET /v1/cowork/state on the international version, the values dropped ×100 and now match the price actually charged on activation. No code changes are required.
