### 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](/docs/cowork/state) and [GET /v1/cowork/me](/docs/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](/docs/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](/docs/cowork/state) on the international version, the values dropped ×100 and now match the price actually charged on activation. No code changes are required.
