𝜏-knowledge: benchmarking agents on real-world knowledge𝜏-Knowledge measures how well agents can work through messy, evolving knowledge bases to complete complex, multi-step tasks. While models are improving, they still struggle to reliably use this information in practice, leaving a large gap to real-world performance.2026년 5월 13일
Golden articles: Evaluating and improving search Search evaluation shouldn’t be static — it should reflect what actually helps resolve real customer issues. By measuring performance daily against production conversations and feeding those signals back into the system, we've built a continuously improving system for resolving customers’ needs. 2026년 4월 14일
Meet Linnaeus and Darwin: Search models that drive higher resolution ratesOur purpose-built retrieval and reranking models outperform off-the-shelf ones, driving up to 16 percentage point improvements in resolution rates.2026년 4월 3일
𝜏³-Bench: Advancing agent benchmarking to knowledge and voice𝜏³-Bench is here. We've expanded agent evaluation to two new frontiers: knowledge retrieval and voice.2026년 3월 18일
