hey - this new model is amazing ... it's SOTA on SWE Bench for a 32b model, scoring 37% which is SHOCKING for a model this small ... would love to see this on Workers AI https://huggingface.co/all-hands/openhands-lm-32b-v0.1

IIsaac McFadyen And what models does this occur on?

Brandon Studio•4/1/25, 2:12 AM

I see the two models (

@hf/nousresearch/hermes-2-pro-mistral-7b

@hf/nousresearch/hermes-2-pro-mistral-7b

and

@cf/meta/llama-3.3-70b-instruct-fp8-fast

@cf/meta/llama-3.3-70b-instruct-fp8-fast

) behaves differently.
Response of hermes does not handle

<tool_call>

<tool_call>

label in stream mode, as shown in Image 1.
Response of llama 3.3 does not distinguish text content and tool call, as shown in Image 2.

Brandon Studio•4/1/25, 2:14 AM

I expect the tool call response to present in

tool_calls

tool_calls

field rather than

response

response

field, just like non-stream mode

Hello. Does anybody have experience using a custom lora on Workers AI? I uploaded the lora files and the finetune is listed via "wrangler ai finetune list", but when I try and do inference via curl with the finetune ID reported by wrangler, it says finetune not found. The adapter works on huggingface with the same files, and I can do inference on the base model (mistral 7b instruct v0.2) via curl fine. Does anybody know the right way to do this?

This is the error I'm getting (all redacted fields filled in properly):

I've heard it's a powerful programming language, but I'm not exactly sure how it all fits together. Let me start by breaking down what I know and what I need to figure out.\n\nFirst, I know that C++ is an extension of C. So, it includes everything from C but adds more features. But what exactly are those features? I remember something about classes and objects, which makes me think it's object-oriented. That must mean it's good for building large applications where you can structure code more cleanly.\n\nThe assistant mentioned that C++ is compiled, which I think means it's faster because it's converted directly into machine code. But I'm not entirely sure how that process works compared to interpreted languages. Maybe I should look into the compilation steps, like preprocessing, compiling, assembling, and linking. Understanding that could help me see why C++ is efficient.\n\nI'm also a bit confused about the Standard Template Library (STL). I know it's part of C++, but how does it help? It sounds like it provides a lot of useful data structures and algorithms, which would save time when coding.

it's certainly possible to put a language detection model in front, but that defeats the cost and latency benefit from using the serverless models on workers ai, especially since other whisper providers (openai, fireworks, groq) already provides it
