Hi, wanted to ask the community here if there is a combination you find works well together of a Agentic Code CLI and a Model from Workers AI specifically. If your familiar with Claude Code, that's what I'm trying to determine if I could build a lower cost cloudflare based version of. Ideas?

Paul•11/13/25, 4:25 PM

For example I tried combining Aider CLI with Amazon Nova (Not on cloudflare, just an example), and now I'm wonder if I can do the same with Cloudflare hotsed models? - BTW the Aider/Nova combination isn't working too well for me so far

IME the cloudflare hosted models tend to be a bit more expensive then other providers. If you want low latency/edge usage, it's great, but if pure cost is your benchmark then other providers will get you a bit better pricing

Paul•11/13/25, 4:25 PM

Ok, thanks for the insight. I guess I didn't do a cost analysis, for some reason I sort of assumed they would be cheaper on cloudflare

like most stuff

PhoenixSpace•11/13/25, 4:28 PM

If you need to scale and run AI stuff globally/on the edge, their pricing is fantastic. If it’s just a single user internal tool, there are slightly cheaper options

Paul•11/13/25, 4:29 PM

I need to get my head around "Neurons" pricing - so I can comapre apples to apples with other solutions.

PhoenixSpace•11/13/25, 4:30 PM

The model pages usually have price per M tokens

Hey! so According to chat gpt I can use worker AIs to make my self a AI api, but it says there is limit, it said something about 10,00 neurons per day, now I wanted a better source so is this true? and if so how many neurons per task?

boke0•11/15/25, 12:45 AM

Hi there, I could use some help.
A few days ago, my product, which is built on Cloudflare Workers and integrates with Workers AI (GPT-OSS-120b) through bindings, broke because the interface changed (prompt_tokensprompt_tokens and completion_tokenscompletion_tokens were replaced with input_tokensinput_tokens and output_tokensoutput_tokens).
And today, I ran into another issue: the instructionsinstructions parameter stopped working when the input was in an OpenAI-like format (like [{role: "assistant", content: "foobar" }, ...][{role: "assistant", content: "foobar" }, ...]).

Where can I check for these kinds of interface changes in advance so I can update my product before it breaks?

Google vertex and Amazon bedrock running the same model is usually a bit cheaper, same with fireworks AI and deepinfra

Similar in pricing is groq (not to be confused with grok!) but faster output

This is why I’m stoked about Replicate, I think this is gonna be huge

Hello everyone, my Workers AI returned Error 1101, and the reason in the statistics is Uncaught Exception. How should I troubleshoot this?

Catkin038•11/22/25, 10:39 AM

I found the problem, 5028: This model was deprecated on 2025-10-01. Please use an alternative model.

Catkin038•11/22/25, 10:42 AM

I need to confirm whether @cf/qwen/qwen2.5-coder-32b-instruct still accepts support.

Why did he deceive me? Even if I mistakenly joined that server, I should have been able to realize it was fake quickly.

Hello everyone, I've noticed that my Workers AI sometimes encounters the 5028 issue, but querying @cf/qwen/qwen2.5-coder-32b-instruct is still supported. After receiving an email in September, I updated the model referenced in my code. Is it possible that some of Cloudflare's data centers are not using the latest code?

Hi, I'm using the OpenAI api for embeddings and getting a lot of 500 errors with the qwen3-embedding-0.6b model. Around 100 requests per minute, 20 inputs per batch, small chunks. Seems ok for 5 minutes then the errors start to pile up. My app handles 3 retries.

blah•11/24/25, 3:50 PM

Hey Cloudflare AI team / #workers-ai,
We're hitting a wall with high Time-to-First-Token (TTFT) latency on one of our streaming applications using Workers AI. Need some insight if this is expected for the model we're using.

The Problem:
Our application is experiencing an approx 4.0 second delay before the LLM starts streaming any output.

Our Setup:
Model: @cf/meta/llama-3.1-8b-instruct-fp8
Worker Region: MIA (Miami)
Prompt Size: approx 1,144 input characters (RAG context).Worker Performance:Total Wall Time: 4,474 ms
Worker CPU Time: 16 ms
(Conclusion: Almost all time is spent waiting on the model to start generation, not our code.)

Questions:
Is a 4.0+ second TTFT common for the llama-3.1-8b-instruct model at this prompt length?
Are there specific provisioning tips, or is the *-fast variant recommended solely for reducing this TTFT?

Any advice on further optimizing TTFT on Workers AI is appreciated!

Thanks!

acusti•11/24/25, 4:04 PM
