huh i can get function calling to work but for llama instruct it sometimes just hangs without giving a response

Z

zsueo•9/3/25, 11:58 PM

id say it works around 30% of the time

zsueo•9/3/25, 11:59 PM

it also likes to leak the function call into plain text

im super excited about workers ai https://blog.cloudflare.com/workers-ai/

and curious what's the latest status on it? im primarily looking into deploying my custom python script + model with compilation graph cache and see if cloudflare is able to run it at global scale serverless. with great cold start time.

for models im mean tasks like

1) upscaling

3) ad-hoc AI processing
4) or even large diffusion transformer models that could take minimum of H100 to run if that's on the roadmap

I'm testing aura-1 text2speech. There is no mentioning of Text input limit, but it seems to have 2k symbols limit (as I understand Deepgram have this limit). When the text is bigger - there is no proper error message, please fix (and add to doc)

maj•9/5/25, 5:52 AM

I'm trying to use AutoRAG to spell check names. I have a list of names in a R2 bucket (split in ~3MB chunks). AutoRAG claims it finished processing them. I then use

c.env.AI.autorag('my-rag-name').aiSearch()

c.env.AI.autorag('my-rag-name').aiSearch()

c.env.AI.autorag('my-rag-name').aiSearch()

c.env.AI.autorag('my-rag-name').aiSearch() to ask it basically "give me the correct version of the given name". Hoping it would fix the spelling of "Suma Covjek" to "Šuma Čovjek", as listed in one of the files. But results are underwhelming. When I looked at the AI Gateway and what the

aiSearch()

aiSearch()

aiSearch()

aiSearch() used for the default system message, I see "...no relevant documents were retrieved for the user's query...". For each and all of them. If I do a search in the playground it would sometimes return a file, but often not the right or relevant one, even if the exact correct spelling is given. What am I missing? How come

aiSearch()

aiSearch() would not find my content?

Hi friends, has someone been able to add workers-ai to vs code extension cline or similar? I've been trying for months with no success. I tried the openai-compat providor route but kept getting errors. I've already connected in cline groq, mistral, cerebus, openrouter, gemini, and it was quite straight forward. Workers-ai in cline would be awesome. Btw I got curl test to work easily with and without ai gateway.
