## Which one, for what

### Fireworks AI Inference (BB)

Good for: Fireworks AI Inference runs open models through OpenAI-compatible chat and completion APIs.

Ahead on:
- Reliability, 70 against 45
- Schema & documentation, 93 against 59
- Agent ergonomics, 80 against 71
- Security & auth, 85 against 62
- Maintenance & community, 65 against 44
- Transparency & trust, 66 against 38

Also in its favour:
- Agent-ready, a grade of BB or better

Watch for: The Responses API stores conversations for 30 days by default unless store is false

### RouterPlus (D)

Good for: Teams that call Claude and GPT models from one key and want the cost of every call in the response, with their own provider keys where they have them.

Watch for: No terms of service, privacy policy, status page, changelog or security.txt found for the gateway

## Verdicts

**Fireworks AI Inference.** Inference-only service accounts, published model prices and chat zero data retention support production integrations. Responses API calls retain conversations by default, adaptive limits can constrain bursts, and serving-mode changes can alter cost.

**RouterPlus.** The docs are written for agents, every model price is public, and each response carries its own cost. No terms of service, privacy policy, status page or changelog were found. Signup adds no free credit, and the chat catalogue is Claude and GPT only.

## Before you call either

### Fireworks AI Inference

1. Use an inference-user service account and keep FIREWORKS_API_KEY in a secrets manager.
2. Use https://api.fireworks.ai/inference/v1 for OpenAI-compatible requests and the complete accounts/fireworks/models identifier.
3. Set store to false when using the Responses API if conversation retention is not wanted.
4. Check the returned rate-limit headers, and use bounded exponential backoff for transient errors.
5. Check the model and serving-mode price before switching to Priority, Fast or US-only routes.

### RouterPlus

1. Send `max_tokens` on every request. Without it the balance hold assumes up to 32,768 output tokens and can return `insufficient_quota` on a small balance
2. Switch on `error_type`. Retry `rate_limit` after `retry-after`, and stop on `insufficient_quota`, which needs a person to add credit or raise a cap
3. Don't add a retry loop on top of the SDK's. There is no idempotency key, so a retry that reaches a provider is billed again
4. Copy model ids from `GET /v1/models` or /api/models.json. An unknown id is a 404 and the gateway never substitutes one
5. Use `/v1/messages` for Claude when you need `thinking` or server tools, and `/v1/chat/completions` with `response_format` only for GPT ids
