Need Flux enabled for project - /v1/listen returns HTTP 400

[rjtdesign]

Hi Deepgram team,

Can you please enable Deepgram Flux streaming STT for my project, or confirm the exact model slug?

Project ID:
bb5b3a14-cb4f-43c5-a5a2-be9332a03f4e

Nova-3 works with the same API key, but Flux does not work.

Tested on /v1/listen websocket:

• flux-general-en
• flux-general-multi
• flux
• flux-general
• flux-general-en-us

All return HTTP 400.

Also, /v1/models returns no Flux models for this API key.

Nova-3 opens successfully, and conversationalai opens successfully.

Example request IDs:
019ed175-208e-7fe0-a058-4374cece59b8
019ed175-21a4-7320-ae46-b0401563931e
019ed175-2f67-77b3-b4fd-4b82d5d57715

We need Flux for a production voice-agent use case. Please confirm whether Flux is available for this project and what exact streaming model slug to use.

It looks like we're missing some important information to help debug your issue. Would you mind providing us with the following details in a reply?

• The programming language you are working in (e.g. JavaScript, Python).

[rjtdesign]

Thanks. Here are the details:

Programming language:
Python and Node.js

Use case:
Production realtime voice agent using LiveKit Agents Python worker with Deepgram streaming STT.

Endpoint:
wss://api.deepgram.com/v1/listen

Project ID:
bb5b3a14-cb4f-43c5-a5a2-be9332a03f4e

Working model:
nova-3 works successfully with the same API key.

Also working:
conversationalai opens successfully.

Failing Flux model slugs:

• flux-general-en
• flux-general-multi
• flux
• flux-general
• flux-general-en-us
• flux-general-en-US

All Flux slugs return HTTP 400 during websocket handshake.

Minimal failing request:
wss://api.deepgram.com/v1/listen?model=flux-general-en&encoding=linear16&sample_rate=16000&channels=1

LiveKit failing request:
wss://api.deepgram.com/v1/listen?model=flux-general-en&punctuate=true&smart_format=false&no_delay=true&interim_results=true&encoding=linear16&vad_events=true&sample_rate=16000&channels=1&endpointing=25&filler_words=true&profanity_filter=false&numerals=false&mip_opt_out=false&language=en

Example request IDs:
019ed175-208e-7fe0-a058-4374cece59b8
019ed175-21a4-7320-ae46-b0401563931e
019ed175-2f67-77b3-b4fd-4b82d5d57715

We also called /v1/models with this API key. It returns 408 STT models but zero models containing "flux".

Question:
Is Flux enabled for this project? If yes, what exact streaming model slug should we use? If not, can you enable Flux for this project?
