BWhat changed
Released the Grok-1 base checkpoint and JAX reference implementation with explicit sparse-expert, grouped-KV and tokenizer specifications, enabling public model-level research.
Scientific scope
Released the Grok-1 base checkpoint and JAX reference implementation with explicit sparse-expert, grouped-KV and tokenizer specifications, enabling public model-level research. Open resource/system contribution, not invention of MoE, RoPE or grouped KV. October2023 pretraining differs from March2024 open release; checkpoint is not dialogue-tuned Grok service or later Grok3. Reference MoE implementation expressly prioritizes straightforward correctness over efficiency.
