SynthTraces
A minimal codebase to generate synthetic coding agent session traces using Pi.
Each session pairs two models working inside one of the project codebases:
a remotely hosted open model (e.g. deepseek-ai/DeepSeek-V4-Pro, openai/gpt-oss-120b, Qwen/Qwen3.6-27B) backs the coding agent, equipped with the default Pi tools — read, write, edit, and bash;
a local model running in llama.cpp plays the user, opening with one of the starting questions and driving the… See the full description on the dataset page: https://huggingface.co/datasets/julien-c/synthtraces.africa-synth-aid-flows-medical-multimodal-fracture-all

MachineLearningLM Pretraining Corpus
This repository contains the pretraining corpus for MachineLearningLM, a framework designed to equip large language models (LLMs) with robust in-context machine learning (ML) capabilities. The dataset consists of ML tasks synthesized from millions of structural causal models (SCMs), spanning various shot counts up to 1,024. It is designed to enable LLMs to learn from many in-context examples on standard ML tasks purely via in-context learning… See the full description on the dataset page: https://huggingface.co/datasets/MachineLearningLM/machinelearninglm-scm-synthetic-tabularml.2026-09-15-da-lowstakes-refresh-synth

Coding agent session traces for aaaaliou/pi-synthetic
This dataset contains redacted coding agent session traces collected while working on git@github.com:aliou/pi-synthetic.git. The traces were exported with pi-share-hf from a local pi workspace and filtered to keep only sessions that passed deterministic redaction and LLM review.

Abstract
Modern T2V/I2V generators synthesize people increasingly hard to distinguish from authentic footage, while current evaluation suites lag: legacy benchmarks target manipulation-based forgeries, and recent synthetic-video benchmarks prioritize scale over realistic human depiction.

Raw experimental outputs from the Synthetic Social Networks study:
59,776 in-character LLM-agent posts from 528 production trials, and
64,562 posts total when the original pipeline-verification runs are

trial includes peer-vote traces from in-character voting by other agents.… See the full description on the dataset page: https://huggingface.co/datasets/ranausmans/synthetic-social-networks.typed-decisions-synth
Typed Decisions Synth
This is the synthetic dataset I made for Hmm, a small open model that answers questions about your data with probabilities instead of text.
It has 7,414 cases with 25,859 questions across 149 domains and workflows. Every question has an answer and a soft label (a probability for every option), so you can train a model to be unsure when it should be.

A vintage finetuning dataset (~416k rows, eleven task routes). Sourced by taking excerpts
from pre-1930's texts, turning these into verbatim answers, and then using deepseek-chat to
generate period-appropriate questions of those answers. Any model tuned on this dataset should,
theoretically, never update its weights on anachronistic text, since questions are masked in the
finetuning stages. Features composition, verse, narrative, reasoning, multiturn dialogue, and
calibrated uncertainty… See the full description on the dataset page: https://huggingface.co/datasets/zachnorton03/synthetic-pre1930-sft.FacturaRD-Synth

Dataset Card for SynthPAI
SynthPAI was created to provide a dataset that can be used to investigate the personal attribute inference (PAI) capabilities of LLM on online texts. Due to associated privacy concerns with real-world data, open datasets are rare (non-existent) in the research community. SynthPAI is a synthetic dataset that aims to fill this gap.
