What is Grok 4.1 Fast?

Grok 4.1 Fast is xAI’s state-of-the-art tool-calling model built to meet the needs of modern enterprise agents that require long-context reasoning, fast inference, and reliable real-world performance. It supports an expansive 2-million-token context, allowing it to maintain coherence during extended conversations, research tasks, or multi-step workflows without losing accuracy. xAI trained the model using real-world simulated environments and broad tool exposure, resulting in extremely strong benchmark performance across telecom, customer support, and autonomy-driven evaluations. When integrated with the Agent Tools API, Grok can combine web search, X search, document retrieval, and code execution to produce final answers grounded in real-time data. The model automatically determines when to call tools, how to plan tasks, and which steps to execute, making it capable of acting as a fully autonomous agent. Its tool-calling precision has been validated through multiple independent evaluations, including the Berkeley Function Calling v4 benchmark. Long-horizon reinforcement learning allows it to maintain performance even across millions of tokens, which is a major improvement over previous generations. These strengths make Grok 4.1 Fast especially valuable for enterprises that rely on automation, knowledge retrieval, or multi-step reasoning. Its low operational cost and strong factual correctness give developers a practical way to deploy high-performance agents at scale. With robust documentation, free introductory access, and native integration with the X ecosystem, Grok 4.1 Fast enables a new class of powerful AI-driven applications.

What is GPT-6 Luna?

GPT-6 Luna is OpenAI’s efficiency-focused GPT-6 model for developers and users who need capable reasoning, coding, computer use, and agentic workflows at very low inference cost. It is positioned below GPT-6 Sol and GPT-6 Astra in the model family while bringing many of the GPT-6 generation’s improvements to applications that prioritize scale and affordability. The model supports configurable reasoning effort so developers can allocate additional computation to complex tasks while keeping simpler interactions fast and economical. GPT-6 Luna can power business automation across applications used for sales, marketing, finance, operations, customer support, and human resources. Its coding capabilities support work on real software repositories, including multi-step engineering tasks that require analysis, modification, testing, and iteration. Luna can also operate in computer-use environments, allowing agents to navigate graphical interfaces and complete extended workflows across software applications. OpenAI reports that GPT-6 Luna substantially improves factual reliability compared with GPT-5.6 Luna and can approach the capabilities of more expensive models on some tasks when used at higher reasoning levels. The model also benefits from GPT-6’s improved collaboration style, with clearer technical communication, less unnecessary jargon, and fewer low-value details. Enhanced prompt caching allows applications to reuse previously processed context at a discount while preserving cache reuse when reasoning effort or available tools change. These efficiency improvements make Luna suitable for high-volume agents, coding assistants, automated workflows, customer-facing applications, and other systems where per-request cost is important. GPT-6 Luna is available through the OpenAI API as gpt-6-luna, as well as through ChatGPT Work, Codex, and supported ChatGPT desktop experiences.
