[FLARE](https://github.com/jzbjyb/FLARE) reports 669 GitHub stars, 62 forks, and 17 open issues, last pushed Nov 20, 2023. [filco](https://arxiv.org/pdf/2311.08377.pdf) has 198 stars, 20 forks, and 2 open issues, last pushed Apr 6, 2024. Figures are from public GitHub metadata via [FLARE's repository](https://github.com/jzbjyb/FLARE) and [filco's repository](https://github.com/zorazrw/filco). | | [FLARE](/tools/jzbjyb-flare.md) | [filco](/tools/zorazrw-filco.md) | | --- | --- | --- | | Tagline | Forward-Looking Active REtrieval-augmented generation | [Preprint] Learning to Filter Context for Retrieval-Augmented Generaton | | Stars | 669 | 198 | | Forks | 62 | 20 | | Open issues | 17 | 2 | | Language | Python | Python | | Adopt for | FLARE is a retrieval-augmented generation tool written in Python, aimed at enhancing specific use cases through active learning and forward-looking approaches.

It operates under the MIT license. ## Choose when ### Choose FLARE if… - License: FLARE is MIT, filco is CC-BY-SA-4.0. - Tags unique to FLARE: conda environment, python dependencies. - - Use FLARE specifically when you need an active-learning approach to retrieval that takes into account future relevance for the generated content. ### Choose filco if… - License: filco is CC-BY-SA-4.0, FLARE is MIT. - Tags unique to filco: dialog-generation, fact-verification, flan-t5, llama2. - Also covers Evaluation & Observability. ## When NOT to use FLARE - - Avoid FLARE if your project requires more generalized or passive retrieval methods that don't integrate active learning and forward-looking insights. - - If you're working in an environment without Conda support, you may face dependency management challenges that could complicate the setup process with `setup.sh`. ## When NOT to use filco - Last GitHub push was 826 days ago (dormant maintenance, Apr 6, 2024). Validate activity before betting a new project on filco. - Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough. - Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers. ## Common questions ### What is the difference between FLARE and filco? FLARE: Forward-Looking Active REtrieval-augmented generation. filco: [Preprint] Learning to Filter Context for Retrieval-Augmented Generaton.

FLARE has more GitHub stars (669 vs 198). Stars measure visibility, not whether either tool fits your constraints. ### Are FLARE and filco open source? Yes - both are open-source projects on GitHub (FLARE: MIT, filco: CC-BY-SA-4.0). ### Where can I find alternatives to FLARE or filco? GraphCanon lists graph-backed alternatives at [FLARE alternatives](/tools/jzbjyb-flare/alternatives) and [filco alternatives](/tools/zorazrw-filco/alternatives) ([FLARE markdown twin](/tools/jzbjyb-flare/alternatives.md), [filco markdown twin](/tools/zorazrw-filco/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/jzbjyb-flare-vs-zorazrw-filco.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, FLARE or filco? FLARE: Dormant. filco: Dormant. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for FLARE and filco? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [FLARE trust report](/tools/jzbjyb-flare/trust); [filco trust report](/tools/zorazrw-filco/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=jzbjyb-flare`](/api/graphcanon/graph?tool=jzbjyb-flare) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
