function-calling-sharegptThis is a dataset for finetuning models on function calling based on glaiveai/glaive-function-calling-v2.
The dataset includes 86,864 examples of chats that include function calling as part of the conversation. The system prompt includes either 0, 1, or 2 functions that the assistant can use, and instructions on how the agent can use it.
Changes include:
Using ShareGPT format for chats
Adding "function_response" as a role
Removing code examples

Narrative Function Calling v1
Welcome to Narrative Function Calling v1! This dataset is purpose-built for training (or fine-tuning) models that produce consistent, structured function calls in conversation-like settings. The dataset integrates and normalizes data from both Glaive Function Calling v2 (Apache License 2.0) and Salesforce XLAM function calling data (CC-BY-4.0)[^liu2024apigen]. It provides a clean, rich, and comprehensive set of examples that guide large language models… See the full description on the dataset page: https://huggingface.co/datasets/narrative-io/narrative-function-calling-v1.function-calling-ja-trial

🛑 Most Function-Calling Failures Are Not Schema Failures. They Are State Failures.
The model believes the world is still valid — when reality has already changed.
It calls the right tool with stale beliefs, gets "success", and moves on. That is how agents silently corrupt production state.
This dataset trains argument-level correctness under changing state: multi-turn tool use, error recovery, and explicit verification steps — not just happy-path calls.

OpenAI Function Calling Format (5K)
Synthetic function-calling conversations in the OpenAI messages format (tool_calls / tool role).
Why This Dataset
Compatible with GPT-4, Mistral, Llama-3.1, Qwen2.5, and any model trained on the OpenAI chat format. Most existing function-calling datasets use abstract schemas — this uses the exact wire format models see in production.
Dataset Description
5,000 conversations across 10 tool types:

GLM-5.3-Flash Function Calling (multi-turn agentic, Coding/DevOps)
Synthetic multi-turn agentic function-calling conversations generated with
zai-org/GLM-5.3-Flash via HF Inference Providers.
Format: OpenAI chat messages with a tools array of JSON-schema function definitions.
Assistant turns carry tool_calls; tool outputs are model-simulated (role: "tool").

function-calling-pt-pt
English function-calling conversations translated into European Portuguese (pt-PT). Only the natural-language turns are translated. Tool definitions, calls and tool results stay in English, exactly as in the source, so a model learns to take a request in Portuguese and call an English API with the right arguments.
