Bbosuutap How many requests can do with 10k neurons?

Depend on model and input/output token

10K neurons ~ 0,11$

If you uses gpt-oss-120bgpt-oss-120b,
If each request use ~10K input tokens and ~1K output tokens (avg of most AI agent)
=> 10000/1000000*0.35 + 1000/1000000*0.75 = $0.00425/request10000/1000000*0.35 + 1000/1000000*0.75 = $0.00425/request
=> $0.11 / $0.00425 = ~25 requests

If you just chat, each request spends ~100 input token and ~100 output token
=> 100/1000000*0.35 + 100/1000000*0.75 = $0.00011/request100/1000000*0.35 + 100/1000000*0.75 = $0.00011/request
=> $0.11 / $0.00011 = ~1000 request

Both my dev and deploy version for AI worker used to work perfectly fine. But last few days, the deploy version Ai worker stop working. Have been trying troubleshoot for the last two days. The dev version still working fine. Anyone know why?

Hey @koalaspider . Can you expand a little on what has stopped working, e.g. is it the inference requests? something else?

This appears to happen intermittently, I have had this occur in the past, and it eventually resolves itself.

Yes, these generally don't last long. But the problem is that when they occur they basically break my app. So I need some kind of a fallback so that my users can continue to be served.

Hi @samjs, the AI does not respond on the deploy version but the dev version works fine. I rebuilt everything on the deploy version yesterday. The built process was completed and no error. But when it comes to wrangler deploy, it said "A request to the Cloudflare API failed.
Authentication error [code: 10000]"

If it's wrangler deploy that's failing it might be worth asking in #wrangler or even #general-help -- those folks might be able to provide more help in debugging this.

Types for workers AI feel mostly abandoned at this point sadly. I’ve raised it again and again, both publicly and privately, and there’s never any real conclusion:

- https://github.com/cloudflare/workerd/issues/5080
- https://github.com/cloudflare/workerd/issues/2418
- https://github.com/cloudflare/workerd/issues/2181

If you want good DX, with a maintained platform, sdk, and reliable inference, I’d personally recommend using vercel’s ai sdk and OpenAI directly at this point unfortunately.

So, the method that I used above works but it's kind of finicky. The response is kind of inconsistent at it throws a lot of internal errors. So, I'm currently using the direct WebSocket connection according to Deepgram's website https://developers.deepgram.com/docs/flux/quickstart (works well). I'll try Cloudflare's implementation later.

Getting Started with Flux | Deepgram's Docs

Flux is the first conversational speech recognition model built specifically for voice agents. Unlike traditional STT that just transcribes words, Flux understands conversational flow and automatically handles turn-taking.

Wow, that's really unfortunate. No indication that they'll work to improve workers AI? I'm a bit new to CF's inference, but what do you mean by (not) "reliable inference"? Is the latency all over?

samjs•10/23/25, 3:10 PM

Hey @James , @carter and others. Apologies for the slow progress here, and I understand and share the frustration.

We are absolutely working on fixing these issues, and we hope to have an update soon. We've got a little backed up on some work here, but should be getting around to it soon. To give you an idea of the kinds of things we've been working on:

- Improved platform stability and performance: we've recently rolled out a lot of "invisible" changes to make the platform more stable to things like high load and more consistently return successful responses. While there will still be occasions that people will see 3040 errors due to limited capacity, these should be much less often than before
- For the gpt-oss models, we've been waiting for some vLLM changes to land before pushing out more updates. In hindsight we shouldn't have let ourselves be blocked on this, and we're working to address this by seeing if we can build this ourselves internally. That's going to bring streaming, chat/completions support, and support for async requests. Along with a number of bug fixes.
- Support for realtime audio models like deepgram/flux, and websocket support for those.

On the DX front -- all the feedback that gets shared here/in GitHub is absolutely heard internally. e.g. you have @Kevin and I both core member of the Workers AI team checking this regularly.

James

James•10/23/25, 3:33 PM

Thanks Sam, excited for updates. I'd love to see DX around types with model releases a clear focus, so that models aren't added to the platform with an immediately negative DX. Other platforms have types available with great DX on day one or two, especially for platforms they advertise as a "partner", but some models on Cloudflare end up weeks, or even months out of date, if not missing entirely.

samjs

S

samjs•10/23/25, 3:37 PM

Agreed. We have a process and tooling problem we need to fix here. On the former, as you say we've been way to slow to update types along with model releases. And on the latter, currently updating types is a somewhat manual process for us (which obviously feeds into the former).

Hey @Razmjoo , thanks for reporting! And thank you Zegevlier for jumping on it.

With respect to the timeouts: I'm not seeing any indications of an outage. I can see the spike in inference times that would have caused the timeouts, but there's no correlation with location/server or anything like that to suggest there's a bug. And no other accounts were experiencing any spikes. Were the inputs particularly long? E.g. using reasoning high as well?
