+## [2.1.0] - 2026-09-15
+### Added
+- **`OpenAiSpeaker`** and **`OpenAiReasoner`** — new optional fields on `OpenAiModel` for configuring the GPT-Live speaker (instructions, personality packs) and its delegated reasoning model (model, effort, instructions).
+- **`AnthropicBedrockModelFallbackModelsItem`** — new enum and optional `fallbackModels` field on `AnthropicBedrockModel` for specifying a same-provider Bedrock fallback model tried when the primary fails.
+- **New Rime AI voice models and IDs** — `coda` and `mistv3` added to `RimeAiVoiceModel` and `FallbackRimeAiVoiceModel`; seven new voice IDs (Clementine, Walnut, Eyre, Bancroft, Hesse, Beatty, Godfrey) added to `RimeAiVoiceIdEnum` and `FallbackRimeAiVoiceIdEnum`.
+- **`HipaaSpecial`** (`"hipaa-special"`) added to `InviteUserDtoRoleZero` and `UpdateUserRoleDtoRoleZero` for HIPAA-specific user role assignment.
+- **`ModelCost.seconds`** and **`ModelCost.usageComplete`** — new optional fields reporting provider-billed duration and whether reported usage is complete.
