xAI open-sourced its Grok Build CLI tool after the tool was discovered uploading entire user directories—including SSH keys, password databases, and personal files—to xAI's cloud infrastructure without explicit consent. The codebase comprises 844,530 lines of Rust, with data retention now disabled by default and all previously retained user data deleted. Users can now audit the code themselves and run Grok Build locally without uploading to xAI's servers.
Thinking Machines released Inkling, an open-source multimodal language model with 1 trillion parameters that accepts images, text, and audio inputs natively. The model has 975 billion total parameters with 41 billion active at any time, supports a 1 million token context window, and was trained on 45 trillion tokens across multiple modalities. Inkling is available on Hugging Face with immediate support in transformers, SGLang, vLLM, and llama.cpp, enabling developers to build multimodal reasoning applications through fine-tuning or remote inference.
