Vertex AI Alternative — One API, 220+ Routes, No GCP Lock-In
Use Vertex AI just for Gemini? TrustedRouter is an OpenAI-compatible API: 220+ model routes, Gemini included, one key, automatic fallback, verifiable privacy.
If Vertex AI is only your Gemini endpoint, you are maintaining a cloud platform to make an API call.
Vertex AI's standard path runs through a GCP project, IAM roles, service accounts, and region selection. TrustedRouter asks you to change one line. The API is OpenAI-compatible: point base_url at the gateway, keep your SDK and code, and get 220+ model routes across 30+ providers, Gemini included, with a single key.
First, a filter. If you want managed training pipelines, feature stores, and deployment tooling, Vertex is a real MLOps platform and a router will not replace it. If Vertex is the endpoint you call Gemini through, this page is for you.
from openai import OpenAI
client = OpenAI(
base_url="https://api.trustedrouter.com/v1",
api_key="YOUR_TRUSTEDROUTER_KEY",
)
resp = client.chat.completions.create(
model="trustedrouter/auto", # or any of 220+ routes
messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)Every model behind one endpoint
Gemini sits next to Claude, GPT, DeepSeek V4, Kimi K2.7, Qwen 3.5, GLM-5, MiniMax M3, Llama, and Mistral. Use the smart-cheap-fast chooser at /choose. Switching models means changing a string.
Providers fail. Requests should not.
When a provider goes down, TrustedRouter rolls the request over to another automatically. Meta-routes go further: trustedrouter/auto picks the best fit per request, trustedrouter/cheap finds the cheapest capable route in a TEE, and trustedrouter/fast optimizes for speed. Latency numbers come from real routed requests at the benchmarks page.
Privacy you can check
The prompt path runs inside a hardware-attested confidential-compute gateway. The source is open, the image digest is published, and attestation is checkable live against your own TLS session. TrustedRouter does not store prompt or output content by default. Details at /security.
Attestation beats a privacy policy.
One curl against the attestation endpoint returns a JWT signed by the CPU vendor's root key, with an image digest matching the published open-source artifact and a binding to your live TLS session, so it cannot be replayed. For compliance review, TrustedRouter provides verifiable architecture plus readiness documentation your compliance team can assess: SOC 2 readiness, HIPAA readiness, DPA, BAA, and subprocessors. Teams routing in Europe can use the EU gateway.
This runs at production scale. A document-processing company scaled from zero to over a billion tokens per week through the attested gateway within three weeks of onboarding.

Questions
Does TrustedRouter serve Gemini?
Yes. Gemini routes are part of a catalog of 220+ model routes across 30+ providers, alongside Claude, GPT, DeepSeek, Kimi, Qwen, GLM, and others. The API is OpenAI-compatible, so you change base_url, keep your SDK and code, and switch models by changing the model id. Meta-routes like trustedrouter/auto pick the best fit per request, and measured latency data from real routed requests is published on the site.
Can TrustedRouter replace Vertex AI's training and MLOps features?
No. TrustedRouter is an inference API, and it does not offer training pipelines, feature stores, or model deployment tooling. If your team uses Vertex as a full MLOps platform, keep it for that work. If Vertex is only the endpoint you call Gemini through, TrustedRouter covers that with one key, automatic provider fallback, and a catalog of 220+ routes across 30+ providers, Gemini included.
How does TrustedRouter handle prompt privacy?
The prompt path runs inside a hardware-attested confidential-compute gateway. The source is open, the image digest is published, and anyone can fetch an attestation JWT signed by the CPU vendor's root key, bound to the live TLS session. TrustedRouter does not store prompt or output content by default, and routes carry privacy tiers: Open, Zero-Data-Retention, or TEE, where even the serving provider cannot read the prompt.
Is TrustedRouter SOC 2 or HIPAA certified?
No certification claims are made. TrustedRouter publishes SOC 2 readiness and HIPAA readiness documentation, a DPA, a BAA, and a subprocessor list: verifiable architecture plus readiness documentation your compliance team can assess. The underlying architecture can be checked live through attestation rather than taken on trust.
