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.

Thanks, I'll check it them out. I've currently been using fal.ai but it doesn't have all the models that I'm looking for.

Laurence•10/22/25, 8:56 PM

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.

J

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.

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).

S

samjs•10/23/25, 3:38 PM

Kevin and I have been discussing a bunch how we want to improve it. We'll get better

samjs•10/25/25, 2:45 PM

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?

@samjs input were a bit long (maybe around 50,60 kb) but the reasoning was default;

i mean total message (system + user + json schema) were in total around 50-60kb

worker paid vs. free
isn't 300000 per month equals to 10000 per day ??

Z

zegevlier•10/28/25, 12:12 PM

Pretty much, yea. The difference is that with the 300k/month, you can (I think) use all of them up in a single day, then nothing for the rest of the month. With 10k/day, you cannot use any more than those 10k that day

Looking for input from folks testing Cloudflare Workers AI!
I’m using llama-3.1-8b-instruct-fast (free tier) — works fine until prompts go past ~9K tokens, then it starts ignoring system instructions and hallucinating (even though it’s supposed to support 128K context).
Anyone found free-tier models on Cloudflare that handle large contexts more reliably, or just work best for chat systems?
I’m testing a bunch and trying to build a list of the top free-tier models — any pointers would be awesome!

what could be the reason? I don't find the internal code

Ashkan•10/30/25, 8:51 AM

Maybe this is your answer: "Batch processing is useful for large workloads such as summarization or embeddings when there is no human interaction. Using the batch API will guarantee that your requests are fulfilled eventually, rather than erroring out if Cloudflare does have enough capacity at a given time" https://developers.cloudflare.com/workers-ai/features/batch-api/

Cloudflare Docs

Asynchronous Batch API

Asynchronous batch processing lets you send a collection (batch) of inference requests in a single call. Instead of expecting immediate responses for every request, the system queues them for processing and returns the results later.
