{\tau}-bench-LILT: Evaluating Conversational Agents on Realistic Multilingual Tool-Use Tasks

The paper introduces ${ au}$-bench-LILT, a multilingual extension of the ${ au^3}$-bench benchmark that evaluates conversational agents on realistic tool‑use tasks in German, Korean, Turkish, and Farsi across airline, retail, telecom, and banking domains. It localizes every layer of the benchmark, including culturally appropriate customer databases, native‑language user‑simulator prompts refined by contrastive annotation, and tasks tailored to realistic regional scenarios. Evaluation of eight agent models reveals the most significant performance drops in the Korean and Farsi retail domains, with reductions of up to 61 points in pass^4.

Sell More, Play Less: Benchmarking LLM Realistic Selling Skill

The paper introduces SalesLLM, a bilingual (Chinese/English) benchmark for evaluating large language models (LLMs) in realistic sales dialogues. It comprises 30,074 scripted configurations and 1,805 curated multi‑turn scenarios from Financial Services and Consumer Goods, with controllable difficulty and personas. An automatic evaluation pipeline uses an LLM judge for sales‑process progress and fine‑tuned BERT classifiers for end‑of‑dialogue buying intent, while a user model, CustomerLM, is trained to improve simulation fidelity. SalesLLM scores correlate strongly with human ratings (Pearson r = 0.86) and reveal that top Chinese LLMs match junior‑to‑intermediate human salespeople but not experts, with cross‑lingual consistency remaining poor.

Compass-v3: Scaling Domain-Specific LLMs for Multilingual E-Commerce in Southeast Asia

Compass‑v3 is a 245B‑parameter Mixture‑of‑Experts language model tailored for Southeast Asian e‑commerce, featuring 71B active parameters per token and hardware‑efficient expert parallelism. It is trained on 12 trillion multilingual tokens and synthetic e‑commerce instructions, and incorporates Optimal‑Transport Direct Preference Optimization to improve instruction adherence. Benchmarks show it outperforms GPT‑4, DeepSeek‑V3.1, and Qwen3‑235B, and it is already deployed at scale on Shopee, handling over 70% of the platform’s LLM traffic.
