LILT Launches AURORA: First AI Leaderboard to Score Frontier Models on Non-English Agentic Tasks
LILT launched AURORA on September 30, a leaderboard that scores frontier AI models on agentic, multimodal, and socio-cultural tasks delivered in languages other than English. Nearly every published measure of frontier model progress has relied on English-centric or machine-translated benchmarks. AURORA uses tasks designed and verified by native-language domain experts.
Four Evaluation Tracks
- Multilingual Terminal-bench: Coding tasks in software written for native-language users
- Multilingual τ³-bench: Multi-turn customer support across airline, telecom, retail, and banking in target languages
- Multilingual MultiChallenge: Long-context instruction-following, memory, and self-coherence
- Multilingual GAIA-v2-LILT: Agentic reasoning and tool use
Rankings Split by Language
LILT’s initial analysis shows the rankings are not stable across languages. In coding tasks specifically: GPT-5.5 leads in Spanish, Claude Opus 5.5 wins in Japanese, and Muse Spark 1.3 tops in Serbian. Model quality can differ substantially between languages: the model that leads on an English leaderboard may not lead in the target language an enterprise ships to.
The Commercial Argument
Enterprise agent deployments are no longer English-only experiments. Agents now take real actions in customer-facing workflows across dozens of languages, and wrong decisions surface in user complaints, not lab benchmarks. LILT’s CEO Spence Green framed it directly: “The industry is choosing models on a scoreboard that stops at English. That gap used to cost you an awkward translation. Now that agents are taking real actions in the real world, it costs you a wrong decision, and you find out from your users.”
AURORA is developed by LILT’s Applied AI practice, a PhD-led team with ten-plus years in multilingual AI. LILT’s enterprise client list includes NVIDIA, Intel, and L’Oréal. The leaderboard is live at aurora.lilt.com. Private custom benchmarks are available to enterprise teams on request.
