Welcome to NeurIPS 2026 It is lovely to meet you at NeurIPS! Cohere is hiring across a number of pre-training areas, so we are interested in connecting with professionals working in this space. At Cohere, you can make an impact to our advanced frontier models by joining one of our growing teams: Pre-training Data - developing the data pipeline that underpins Cohere’s advanced language models, conducting data ablations to evaluate data quality and constructing pre-training data mixtures to enhance model performance. Pre-training Evaluations - developing better ways to measure base model progress by implementing new/better evaluations for base model capabilities, finding ways to reduce noise in our current model evaluations, or developing evaluation benchmarks that measure model progress at all model scales. Performance Engineering - optimizing the performance of our advanced language models and systems by improving key model training metrics, such as training throughput or ensuring high accelerator utilization. Model Efficiency - building reliable ML systems and pushing the boundaries of LLM inference (and audio inference serving) efficiency, by developing techniques that improve how models execute in production, driving lower latency, higher throughput, and consistent quality across diverse workloads. Multimodal AI - designing and developing cutting-edge multimodal AI systems, integrating various modalities such as text, speech, and vision.
