🔍 Extra findings:

• Models struggle most with handwritten & whiteboard sketches
• UI screenshots are easiest
• End-to-end generation beats decomposed pipelines
• Finetuning on diverse sketch data is key to generalization

📊 We benchmarked top VLMs (GPT-4o, Claude, Gemini) vs. open-weight models (Qwen, LLaMA, Pixtral).

📈 Finetuned open models outperform proprietary ones:

Qwen2.5-VL-7B → FlowSim: 0.614
GPT-4o → FlowSim: 0.786
𝐐𝐰𝐞𝐧𝟐.𝟓-𝐕𝐋-𝟕𝐁 (𝐟𝐢𝐧𝐞𝐭𝐮𝐧𝐞𝐝) → 𝐅𝐥𝐨𝐰𝐒𝐢𝐦: 𝟎.𝟗𝟓𝟕

🧠 We built a large dataset (22K+ samples) of workflow diagrams:

• Synthetic (Graphviz)
• Manual (hand-drawn)
• Whiteboard
• Digital
• UI screenshots

These were paired with structured JSON workflow outputs for training and evaluation.

Multi-task retriever fine-tuning for domain-specific and efficient RAG Retrieval-Augmented Generation (RAG) has become ubiquitous when deploying Large Language Models (LLMs), as it can address typical limitations such as generating hallucinated or outdated information. H...

* Build balanced training datasets for real-world tasks
* Learn how to handle data imbalance
* Get insights on how to design for at-scale deployment

arxiv.org/abs/2501.04652

🌟 Key Features:

* One retriever for many use cases
* Works across languages! 🌍
* Handles structured data like workflows
* Lightweight & fast for production
* Generalizes to new domains & tasks

📊 Our Results:

Multi-task instruction fine-tuning FTW! Our approach beats both BM25 and strong off-the-shelf encoder models across all retrieval tasks (in-distribution and out-of-distribution).

💡 The Challenge:

* RAG needs domain-specific knowledge
* Multiple apps = multiple retrievers = 💰
* Different types of data (steps, tables, fields, ...)

🚀 Excited to share our new work on making RAG actually work for enterprise applications!
We present a recipe to build a custom retriever that handles multiple retrieval tasks simultaneously for domain-specific RAG applications 🧵

We’re really excited to release this large collaborative work for unifying web agent benchmarks under the same roof.

In this TMLR paper, we dive in-depth into #BrowserGym and #AgentLab. We also present some unexpected performances from Claude 3.5-Sonnet

🎉 Excited to introduce BigDocs!

Finally, we outline trade-offs and practical considerations, from latency improvements to deployment strategies. If you’re designing GenAI systems, this is a goldmine of insights!

Evaluation was key: we developed a novel tree-based metric, Flow Similarity, to assess workflow correctness. Plus, we measured each sub-task and RAG component separately for fine-grained insights.

We dive deep into dataset creation, discussing how Task Decomposition guided our labeling efforts. By focusing on smaller tasks, we sped up labeling, reduced costs, and iteratively improved our system.

RAG enhances the system by grounding the generation process in real-time data from the environment. This reduces hallucinations and ensures that the generated workflows are accurate and context-aware.

Task Decomposition allows us to split the workflow generation into two sub-tasks:

1. Outlining the workflow structure
2. Populating inputs for each step

Each sub-task is easier to solve and test, boosting the system’s modularity and maintainability.

We tackle a real-world use case: Workflow Generation. Given a user requirement in natural language, our system generates complex workflows step by step. This involves breaking the problem into smaller, manageable tasks.

Looking to build an LLM-powered app but finding it hard to make it robust? We’ve got you covered! Our new paper explores how Task Decomposition and Retrieval-Augmented Generation (RAG) can help you create reliable systems. 🧵👇
