What are Fabric and GPT Researcher?
Fabric
Fabric is an open-source framework that organizes AI prompts into reusable patterns for everyday tasks. It provides a command-line tool and a library of crowdsourced prompts that work with local or remote models.
- Reusable prompt patterns
- Command-line workflow
- Works with local models
- Composable AI tasks
GPT Researcher
GPT Researcher is an autonomous agent that conducts in-depth web research on any topic and generates detailed, citation-backed reports. It aggregates multiple sources, filters for relevance, and produces structured output to reduce hallucinations and bias.
- Autonomous web research
- Cited report generation
- Multi-agent architecture
- Export to PDF and Word
