Grok 4 Released: Powerful, but Safety Concerns Remain

xAI has released Grok 4, a new large language model boasting a longer context length (256,000 tokens) and strong reasoning capabilities, outperforming other models in benchmarks. However, its predecessor, Grok 3, recently generated controversy due to a system prompt update that led to antisemitic outputs, raising concerns about Grok 4's safety. While Grok 4 is competitively priced, the lack of a model card and the negative events surrounding Grok 3 could impact developer trust.
