 This model was converted to GGUF format from [`katanemo/Arch-Function-1.5B`](https://huggingface.co/katanemo/Arch-Function-1.5B) using llama.cpp via the ggml.ai's [GGUF-my-repo](https://huggingface.co/spaces/ggml-org/gguf-my-repo) space.
 Refer to the [original model card](https://huggingface.co/katanemo/Arch-Function-1.5B) for more details on the model.

+Model details
+The Katanemo Arch-Function collection of large language models (LLMs) is a collection state-of-the-art (SOTA) LLMs specifically designed for function calling tasks. The models are designed to understand complex function signatures, identify required parameters, and produce accurate function call outputs based on natural language prompts. Achieving performance on par with GPT-4, these models set a new benchmark in the domain of function-oriented tasks, making them suitable for scenarios where automated API interaction and function execution is crucial.
+
+In summary, the Katanemo Arch-Function collection demonstrates:
+
+    State-of-the-art performance in function calling
+    Accurate parameter identification and suggestion, even in ambiguous or incomplete inputs
+    High generalization across multiple function calling use cases, from API interactions to automated backend tasks.
+    Optimized low-latency, high-throughput performance, making it suitable for real-time, production environments.
+
+Arch-Function is the core LLM used in then open source Arch Gateway to seamlessly integrate user prompts with developers APIs
+Key Features
+Functionality 	Definition
+Single Function Calling 	Call only one function per user query
+Parallel Function Calling 	Call the same function multiple times but with different set of parameter values
+Multiple Function Calling 	Call different functions per user query
+Parallel & Multiple 	Perform both parallel and multiple function calling
+Training Details
+
+Katanemo Arch-Function collection is built on top of the Qwen 2.5. A blog with technical details leading to our models will be published soon.

+How to use

+We use the following example to illustrate how to use our model to perform function calling tasks. Please note that, our model works best with our provided prompt format. It allows us to extract JSON output that is similar to the function-calling mode of ChatGPT.
+Single Turn Example

+
+model_name = "katanemo/Arch-Function-1.5B"

+Multi Turn Example
+-
+Upon getting results from functions, you can add it to the messages list as a user message and pass it to the model to get responses for users.
+
+# Suppose we receive the following result from the function:

+execution_results = [get_weather_api_result]

+    messages.append({"role": "user", "content": content})
+    return messages
+
+messages = add_execution_results(messages, execution_results)
+
+inputs = tokenizer.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt").to(model.device)
+
+outputs = model.generate(
+    inputs,
+    max_new_tokens=512,
+    do_sample=False,

+    eos_token_id=tokenizer.eos_token_id,
+)
+
+response = tokenizer.decode(outputs[0][len(inputs[0]) :], skip_special_tokens=True)
+print(response)
+
+Then you should be able to see the following output:
+
+The current temperature in Seattle is 62 degrees in Fahrenheit.
