Model Detail
xAI: Grok Code Fast 1
—xAI: Grok Code Fast 1 is a large language model released by xAI. And supports text->text inputs.
xAI: Grok Code Fast 1 is priced at $0.2/M input tokens and $1.5/M output tokens. Operationally the model offers a 256K-token context window, which matters when sizing it for prompt-heavy or latency-sensitive workloads. At this input rate the model sits in the commodity tier and is suitable for high-volume workloads where per-call cost dominates the decision.
The published knowledge cutoff is 2025-09-30, so newer events will not be reflected in zero-shot answers without retrieval.
xAI: Grok Code Fast 1 is best fit for general-purpose chat and instruction-following workloads, high-volume batch jobs where per-call cost dominates the budget, and long-context tasks such as full-codebase analysis or book-length summarization (256K tokens). Treat this as a starting matrix rather than a benchmark verdict — the right deployment usually depends on the specific evaluation suite that mirrors your workload.

Structured Features Overfit Where Random Features Grok
arXiv:2609.15047v1 Announce Type: new Abstract: Xu, Vardi and Safran (ICML 2026) prove that over-parameterized ridge regression over an unstructured random Gaussian feature map groks, with the delay between memorization and generalization growing as $1/\lambda$ in the weight decay. We show that on a
ChatGPT, Grok, and Claude all went down at the same time
OpenAI's ChatGPT, xAI's Grok, and Anthropic's Claude are back online after they all began experiencing issues around the same time on Thursday. At about 11AM ET, ChatGPT started returning error messages for users trying to use the chatbot, with its status page saying there were "elevated errors acro
The Pentagon now has its own version of ChatGPT and Grok

To Grok Grokking: Provable Grokking in Ridge Regression
arXiv:2601.19791v4 Announce Type: replace Abstract: We study grokking, the onset of generalization long after overfitting, in a classical ridge regression setting. We prove end-to-end grokking results for learning over-parameterized linear regression models using gradient descent with weight decay.
