Grok 3: Another Win For The Bitter Lesson

xAI's Grok 3 demonstrates unprecedented performance, matching or exceeding models from established labs like OpenAI and Google DeepMind. The success reinforces the 'Bitter Lesson' principle that scaling compute power consistently outperforms algorithmic optimization in AI development. The paradigm shift from pre-training to post-training has leveled the playing field for newcomers while highlighting the critical importance of GPU access.
