Aptible LLM Gateway Alternative: 7 BAA-Eligible Providers and 71 Models on Concentrate

If you need a HIPAA AI gateway, the number that matters is how many providers and models you can actually send PHI to. Aptible's LLM Gateway covers Anthropic, OpenAI, and Bedrock-hosted models under its BAA. Concentrate covers seven BAA-eligible providers (OpenAI, Anthropic, Google Vertex AI, Azure, Fireworks AI, Fireworks on Azure, and Baseten) and 71 BAA-eligible models, with more providers coming.

Which providers does Aptible's LLM Gateway support?

Aptible's pricing page says its gateway "covers Anthropic, OpenAI, and Bedrock-hosted models under a single BAA." Its supported models docs describe three routes: Anthropic, OpenAI, or Amazon Bedrock. Google is not one of them, so Gemini is not on the list.

Which providers are BAA-eligible on Concentrate?

Today, BAA-eligible providers on Concentrate include:

As of October 2026, that adds up to 71 BAA-eligible models. See Model Fortress for the live list. We keep adding BAA providers, and one BAA with Concentrate covers each new one as it's added. No new contract, no new integration.

Why does provider count matter for healthcare teams?

More providers means more model choices and more places to fail over.

• Gemini under a BAA. Google models through Vertex AI are BAA-eligible on Concentrate.
• Open-weight models under a BAA. DeepSeek V4.1 Flash, GLM-5.3, Kimi K3, Qwen3.8 Max and MiniMax M3 are all BAA-eligible, often at a fraction of frontier prices.
• Failover across clouds. The same model on more than one provider, so a single outage doesn't take your product down.
• No lock-in. Switch models with one line of code instead of signing with a new vendor.

Is Concentrate more than a HIPAA gateway?

Yes. The same API reaches 207 models across 31 providers. Use the BAA-eligible ones for PHI and everything else for the rest of your product, with one key, one bill, and one set of controls: provider allowlisting, data redaction before a request leaves the gateway, SSO, and role-based access control.

How does Concentrate pricing compare to Aptible?

Concentrate is free to use. BAA access is a $499/month subscription, with no per-request fees and no markup on tokens. Aptible bills LLM Gateway usage at list model pricing plus a 15% markup, so its cost grows with every token you send. On Concentrate, the subscription stays the same whether you send a million tokens or a billion.

How do I get started with a BAA on Concentrate?

1. Contact us at concentrate.ai/compliance to sign a BAA ($499/month subscription; no per-request fees or token markup).
2. Enable a HIPAA organization.
3. Restrict PHI routing to providers marked BAA-eligible in Model Fortress.

Under HHS guidance, a cloud or AI service that handles ePHI for you must sign a BAA. You still own your own HIPAA obligations. For more, see our HIPAA Compliant AI Gateway overview.
