@lineai/voice-models

Voice model catalog for the Line AI phone platform: model → tier mapping, explicit intra-tier ordering, and upgrade detection.

Voice agents pin a concrete model ID (gpt-realtime-1.5, gpt-realtime-2.1-mini, …); this package derives the sellable tier (standard | pro | max) from that pin — the inverse of the chat/task tier system, which stores the tier and resolves the model late. Pinned models never change out from under a customer; availableUpgrade() only detects that a newer same-tier model exists.

No prices live here. The service-api rate card (and its Firestore overrides) remains the sole pricing authority; this catalog only tells pricing code which tier a model belongs to and whether it is a reasoning model.

API

import {
  VOICE_MODELS, VOICE_TIERS, DEFAULT_VOICE_MODEL,
  normalizeModelId,   // strips '-2025-10-06' style date suffixes
  modelInfo, tierOf, isReasoningModel,
  currentModelForTier, modelsForTier,
  availableUpgrade,   // highest-rank non-deprecated same-tier model above the pin, or null
} from '@lineai/voice-models';

status semantics:

• current — what a newly created agent in this tier gets.
• available — catalogued and upgradable, but not the default (staging state).
• deprecated — never offered as an upgrade target; existing pins keep working.
