Omni API vs going direct
If you use models from several AI vendors, one aggregated API like Omni saves accounts, integration work and money: one key, one balance, and prices below list. If you depend on one vendor’s newest beta features, need a direct contract or capacity guarantees, or have negotiated your own high-volume rate, going direct is the better choice.
Side by side
| Consideration | Omni API | Separate vendor accounts |
|---|---|---|
| Accounts and keys | One account and one key for every model | One account, key and billing setup per vendor |
| Billing | One prepaid balance; every call shows its charge | A separate bill or credit balance with each vendor |
| Price | About 25% below list for language models; image, video and audio often far lower (see table) | The vendor's list price, or a negotiated rate at high volume |
| Integration | OpenAI and Anthropic request formats; one task model for media | Each vendor's own SDK, formats and async conventions |
| New vendor features | Standard features straight away; unusual or beta options may arrive later or need the passthrough endpoint | Available first, directly from the vendor |
| Contracts and support | Support from Omni (Radiant Crest Inc.) | Direct contract, support and enterprise terms with the vendor |
| Data handling | Requests pass through Omni and an inference provider to the model; Omni does not store prompts or outputs | Requests go straight to the vendor under its own terms |

Vendor prices are their public list prices, checked 15 Oct 2026; the Suno figure is its Pro plan ($10 for about 500 songs). Omni prices are what you are charged today. Image, video and audio calls are billed on the exact work each job does, so prices marked ≈ are typical and a job can cost less. Taxes not included.
How we compared
Vendor prices are their public list prices as published on 15 October 2026: OpenAI’s API pricing page, ElevenLabs’ API pricing page, Suno’s Pro plan, and the official prices of Google, Anthropic, ByteDance, Kling and MiniMax models. Omni prices are what the API charges today, including its margin. Image, video and audio jobs are billed on the exact work each job does, so figures marked ≈ are typical rather than fixed. We do not compare against other aggregators’ prices here because they change often and we could not verify them all.
Trade-offs to know
- An extra hop. Requests pass through Omni and an inference provider, which can add a little latency compared with calling the vendor directly.
- Feature timing. Standard request formats work at once; brand-new vendor-specific options may arrive later.
- Who you contract with. Your agreement is with Radiant Crest Inc., not with each model vendor.
