- Work on projects in language modelling and related areas such as evaluation, multimodal models and optimisation
- Share results through publications, datasets and code
- Contribute to research with practical applications in Cohere’s products
Research internships at AI labs let PhD students work on real training runs and datasets far larger than most universities can offer, and often lead to publications or full-time offers. Cohere’s teams span base model training, retrieval-augmented generation, data and evaluation, safety and fine-tuning.

- Currently pursuing a PhD in machine learning, NLP, AI or a related discipline; the posting also says it will consider exceptional non-PhD candidates
- Work authorisation in the country of employment at hire and throughout the internship
- Experience with large-scale distributed training, data annotation and evaluation pipelines, or implementing state-of-the-art models
- Familiarity with Transformers, strong communication and problem-solving, Python (or C, C++, Lua) and JAX, PyTorch or TensorFlow
Nice to have
- Publications at top venues in machine learning, NLP, AI, computer vision, optimisation, statistics or related fields
- Strong quantitative problem solving and experience with complex, high-dimensional data
Pay and location
Cohere’s posting does not state intern pay. The internship is full-time for 4–6 months in Canada. Note that the posting both says interns must currently be pursuing a PhD and that exceptional non-PhD candidates will be considered.
