# Amazon Bedrock models

> Exact default model identifiers and metering boundaries.

## How Harmonia uses it

Strands cognition uses native Bedrock model IDs. The host selects a role policy, reserves the configured cost, dispatches the request and records the actual model and usage. There is no implicit provider fallback.

| Default model ID                              | Roles                                                            |
| --------------------------------------------- | ---------------------------------------------------------------- |
| `us.anthropic.claude-haiku-4-5-20251001-v1:0` | Intent routing, context assembly, Maya and Nova liaison          |
| `us.anthropic.claude-sonnet-4-6`              | Ryan, Temi, Noni, Dara and Dream synthesis                       |
| `us.amazon.nova-2-lite-v1:0`                  | Nimi evidence analysis                                           |
| `amazon.nova-canvas-v1:0`                     | Native image generation outside the agent tool loop              |
| `amazon.nova-reel-v1:1`                       | Native asynchronous video generation outside the agent tool loop |

Amazon Transcribe owns timed speech transcription; it is not a Bedrock text-model call. ElevenLabs owns instrumental music. See [generated media](/platform/media/generated-media).

## Policy and pricing

`role_models.py` defines role-specific token limits, sampling and deadlines. Model overrides use the corresponding role environment variable. `BEDROCK_TEXT_PRICING_JSON` supplies rates keyed by exact model ID, in USD per million input/output tokens. Missing rates fail closed; no guessed rate is substituted.

`HARMONIA_ALLOW_PAID_AWS` defaults false. Generated images, video and music also require `GENERATIVE_MEDIA_ENABLED`. A true configuration flag does not prove provider readiness or an authenticated invocation.

## Evidence status

`agent/harmonia_agent/role_models.py`, `model_catalog.py`, `usage.py` and `team_runtime.py`. Local contract verification is separate from billed usage reconciliation and live provider proof, which remain pending for this AWS edition.
