According to DeepLearning.AI, the new 'Pretraining LLMs' course developed with Upstage highlights that while prompting or fine-tuning large language models (LLMs) is effective for general NLP tasks, pretraining is critical for building models tailored to specialized domains or underrepresented languages. This has direct trading implications for crypto projects seeking to develop proprietary AI models for blockchain analytics or DeFi platforms, where domain-specific data and terminology are not covered by mainstream LLMs. Traders and developers should note that investing in pretraining can deliver a competitive edge in crypto-focused AI applications, as verified by DeepLearning.AI's official Twitter announcement (source: @DeepLearningAI, May 2, 2025).
