We are excited to announce that we are looking for PhD students for two projects funded by the EPSRC Doctoral Landscape Award! Both projects explore how we can make LLMs more reliable and trustworthy with respect to writing better code or supporting safe clinical decisions. 🧵

Key takeaway: Fine-tuning a 3B LLM yields more effective relevance judgments than few-shot prompting with a 70B LLM, showing that fine-tuning not only improves quality but also saves more query latency.
