Provider: xAI (founded by Elon Musk)
License: Apache 2.0 (fully open-source and commercially usable)
Access: Available on Hugging Face, released March 2024
Architecture: Decoder-only Transformer
Parameters: ~314 billion (dense model)
🔍 Overview
Grok-1 is the first open large language model released by xAI, Elon Musk’s AI company. It is a decoder-only transformer trained from scratch without reinforcement learning from human feedback (RLHF). The model was released in its raw checkpoint form, without fine-tuning or chat optimization, to support transparency and research reproducibility.
Key characteristics:
- 🔓 Truly Open: Apache 2.0 license with raw weights and training metadata
- 🧪 Research-Focused: Not instruction-tuned or chat-optimized — provided as-is
- 📊 High Scale: Competes with top-tier 2023 models in benchmarks like MMLU and HumanEval
⚙️ Technical Details

- Parameters: ~314B (trained on custom cluster)
- Tokenizer: SentencePiece
- Training: No RLHF or post-alignment; trained from scratch
- Context Length: Likely 8K tokens (not explicitly confirmed)
🚀 Deployment
- Hugging Face Repo: xai-org/grok-1
- Supported Use Cases: Research, benchmarking, scaling law studies, academic adaptation
- Notable Constraints: Not chat-optimized out-of-the-box; expect raw generative outputs
