Can DeepSeek accurately scale political text? @glemens.bsky.social just replicated the analyses of our joint Political Analysis paper with DeepSeek and with the newest version of Llama (Llama 3.3 70B). Overall, DeepSeekV3 performs at a level similar to Llama 3.3, but definitely not better. 1/5

📢 Our new paper in Political Analysis explains how to use LLMs like GPT-4o, Llama or Mistral to estimate the ideological and policy position of political texts. Our approach is fast, reliable, cost-effective and reproducible and works with texts written in different languages 1/7 cup.org/4axBEXo
