ToolOrchestra: Elevating Intelligence via Efficient Model and Tool Orchestration

ICML 2026poster

Large language models are powerful generalists, yet solving deep and complex problems such as those of the Humanity’s Last Exam (HLE) remains both conceptually challenging and computationally expensive. We show that small orchestrators managing other models and a variety of tools are able to both pu…

VideoAgentTrek: Computer-Use Pretraining from Unlabeled Videos

ICLR 2026poster

Training computer-use agents requires massive amounts of GUI interaction data, but manually annotating action trajectories at scale is prohibitively expensive. We present VideoAgentTrek, a scalable pipeline that automatically mines training data from publicly available screen-recorded videos, elimin…

BRIGHT: A Realistic and Challenging Benchmark for Reasoning-Intensive Retrieval

ICLR 2025spotlight

Existing retrieval benchmarks primarily consist of information-seeking queries (e.g., aggregated questions from search engines) where keyword or semantic-based retrieval is usually sufficient. However, many complex real-world queries require in-depth reasoning to identify relevant documents that go…

Generative Representational Instruction Tuning

ICLR 2025poster

All text-based language problems can be reduced to either generation or embedding. Current models only perform well at one or the other. We introduce generative representational instruction tuning (GRIT) whereby a large language model is trained to handle both generative and embedding tasks by disti…

Learn-by-interact: A Data-Centric Framework For Self-Adaptive Agents in Realistic Environments

ICLR 2025poster

Autonomous agents powered by large language models (LLMs) have the potential to enhance human capabilities, assisting with digital tasks from sending emails to performing data analysis. The abilities of existing LLMs at such tasks are often hindered by the lack of high-quality agent data from the…

Spider 2.0: Evaluating Language Models on Real-World Enterprise Text-to-SQL Workflows

ICLR 2025oral

Real-world enterprise text-to-SQL workflows often involve complex cloud or local data across various database systems, multiple SQL queries in various dialects, and diverse operations from data transformation to analytics. We introduce Spider 2.0, an evaluation framework comprising $632$ real-world…

EvoR: Evolving Retrieval for Code Generation

EMNLP 2024finding

Recently the retrieval-augmented generation (RAG) has been successfully applied in code generation. However, existing pipelines for retrieval-augmented code generation (RACG) employ static knowledge bases with a single source, limiting the adaptation capabilities of Large Language Models (LLMs) to d…

Lemur: Harmonizing Natural Language and Code for Language Agents

ICLR 2024spotlight

We introduce Lemur and Lemur-Chat, openly accessible language models optimized for both natural language and coding capabilities to serve as the backbone of versatile language agents. The evolution from language chat models to functional language agents demands that models not only master human inte…

One Embedder, Any Task: Instruction-Finetuned Text Embeddings

ACL 2023findings

We introduce INSTRUCTOR, a new method for computing text embeddings given task instructions: every text input is embedded together with instructions explaining the use case (e.g., task and domain descriptions). Unlike encoders from prior work that are more specialized, INSTRUCTOR is a single embedde…

Selective Annotation Makes Language Models Better Few-Shot Learners

ICLR 2023poster

Many recent approaches to natural language tasks are built on the remarkable abilities of large language models. Large language models can perform in-context learning, where they learn a new task from a few task demonstrations, without any parameter updates. This work examines the implications of in…

Taming Pre-trained Language Models with N-gram Representations for Low-Resource Domain Adaptation

ACL 2021long

Large pre-trained models such as BERT are known to improve different downstream NLP tasks, even when such a model is trained on a generic domain. Moreover, recent studies have shown that when large domain-specific corpora are available, continued pre-training on domain-specific data can further impr…
