gemini-2.5-flash-lite model works when I use @google/generative-ai. So problem solved, i think now i can't use own cf-metadata.

HTTP 525 issue with Anthropic models with AI Gateway it seems?

S

SmallShen•9/23/25, 5:24 AM

I think there is a performance issue for ai gateway ui dashboard, if the streaming response is large, clicking(expand) the log would lag for a sec.

There is also a ui bug in dynamic routes dashboard, the background color is incorrect when in dark theme.

noway5566•9/27/25, 2:49 PM

When I test the AI Gateway with stream: true, the response is not delivered in a real-time streaming fashion. Instead, the output only appears all at once after the upstream service finishes processing. In other words, even though I set "stream": true and use Accept: text/event-stream, the gateway buffers the response and returns it all at once instead of streaming it incrementally.

Here’s the sample code I used for testing:

curl -N -X POST https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/compat/chat/completions \
  --header 'Authorization: Bearer {GOOGLE_GENERATIVE_AI_API_KEY}' \
  --header 'Content-Type: application/json' \
  --header 'Accept: text/event-stream' \
  --header 'Cache-Control: no-cache' \

      }
    ],
    "stream": true,
    "temperature": 0.7,
    "max_tokens": 1000
  }' | while IFS= read -r line; do
    echo "[$(date '+%H:%M:%S.%3N')] $line"
  done

        "content": "What is Cloudflare?"
      }
    ],
    "stream": true,
    "temperature": 0.7,
    "max_tokens": 1000

Could you confirm if AI Gateway currently supports real-time streaming passthrough, or if it’s expected behavior that the response is buffered and only returned once the upstream completes?

Acterion•9/27/25, 5:32 PM

New to AI gateway
Trying to set it up with direct connection with OpenWeb-UI hosted on my subdomain (using CF tunnel to my own infra) and constatnly getting CORS errors when sending OPTIONS request to /completions endpoint. Seems like CF either dropping Allow-Cross-Origin headers or/and not working correctly with OPTIONS requests.
Did anyone had success configuring OpenWebUI to work with Gateway before?

hey does anyone know if the AI gateway supports sending audio files in a multi-part form request for STT models like whisper?

I was testing out the groq endpoint but consistently got 400s for valid audio files. URL input seems to work correctly.

misterPaul•9/29/25, 11:26 AM

have you set up "Authenticated Gateway" on the settings page and passed the token in the cf-aig-authorization header as a bearer token

M

misterPaul•9/29/25, 11:38 AM

Go to your AI Search instance > Settings > Models. Is the Gateway field pointing to the correct AI Gateway where you stored the key?
In that specific AI Gateway, under "Provider Keys", is the OpenAI key definitely there and valid?

Those are the two obvious things to check, after that check the "Authenticated Gateway" setting I mentioned

L

Leszek•9/29/25, 11:46 AM

ave you set up "Authenticated Gateway" on the settings page

yes

and passed the token in the cf-aig-authorization header as a bearer token

no. I found no place for that.

I checked again right now and everything works.... So I guess it was an issue on the Cloudflare side.

Thank you for your help!

AI Gateway BYOK Issue: Google Vertex AI Imagen Authentication Fails
Problem
Cloudflare AI Gateway's BYOK (Provider Keys) feature successfully authenticates third-party Vertex AI models (Mistral) but fails to authenticate Google's native models (Imagen), despite using the same service account configuration.

---

What Works

Mistral OCR via AI Gateway BYOK:

await env.AI.gateway("my-gateway").run({
provider: "google-vertex-ai",
endpoint: "v1/projects/my-project/locations/us-central1/publishers/mistralai/models/mistral-ocr-2505:rawPredict",
query: { model: "mistral-ocr-2505", document: {...} }
})
//

200 OK - Works perfectly

---

What Fails

Imagen 4 via AI Gateway BYOK:

await env.AI.gateway("my-gateway").run({
provider: "google-vertex-ai",
endpoint: "v1/projects/my-project/locations/us-central1/publishers/google/models/imagen-4.0-generate-001:predict",
query: {
instances: [{ prompt: "test image" }],
parameters: { sampleCount: 1 }
}
})
//

401 from Google: "CREDENTIALS_MISSING"

---

Configurations Tried

Service account has Vertex AI User IAM role

Added "region": "us-central1" to service account JSON

Tested both :predict and :rawPredict endpoints - both fail

Verified credentials work when calling Vertex AI directly
---

Observation
Third-party publishers (publishers/mistralai/): BYOK authentication works
Google publishers (publishers/google/): BYOK authentication fails

The AI Gateway appears to not generate or pass OAuth2 credentials correctly for Google's native Vertex AI models.

---

Question: Is this a known limitation of BYOK with Google Vertex AI native models, or should this be working?

Marco Ancona•10/8/25, 9:53 PM

Not only Vertex. In the last 4 hours, we saw that all requests to Google AI Studio BYOK via AI Gateway are failing with the error "400 API key not valid. Please pass a valid API key."

We tried to generate a new key and tested the key locally, confirming it works. Still, the error occurs when running via AI Gateway.

Calls to OpenAI via AI Gateway work.

S

stephen•10/9/25, 3:08 PM

My workaround:

Initial attempt (failed):

Provider: google-vertex-ai
Issue: Cloudflare AI Gateway BYOK doesn't support Vertex AI's Imagen endpoints (:predict or :rawPredict on
publishers/google/models/*)
Only Mistral models work with BYOK on Vertex AI (:rawPredict on publishers/mistralai/models/*)Working solution:
Provider: google-ai-studio
Model: imagen-4.0-generate-001:predict
Why it works: Google AI Studio is a separate provider that Cloudflare AI Gateway supports with BYOK, and Imagen 4 isavailable through itKey insight: Even though both Vertex AI and Google AI Studio host the same Imagen 4 model, AI Gateway's BYOK only works with Google AI Studio for Imagen, not Vertex AI. This is likely because they use different authentication mechanisms (Vertex uses service account JSON, AI Studio uses simple API keys).
