xAI Launches Grok 4 Fast: Powerful, Affordable Reasoning AI

xAI has launched Grok 4 Fast, a cost-efficient reasoning model that matches Grok 4’s performance while using 40% fewer tokens and cutting costs by up to 98%. It features a 2M token context window, unified reasoning and non-reasoning modes, and advanced web/X search capabilities for real-time data. Benchmarks show Grok 4 Fast outperforming Grok 3 Mini and rivaling much larger models, while topping LMArena’s Search Arena. Available for free on OpenRouter, Vercel AI Gateway, grok.com, iOS, and Android, it offers developers flexible access through the xAI API in both reasoning and non-reasoning versions. The model introduces state-of-the-art price-to-intelligence efficiency, making high-quality reasoning more accessible than ever. With frontier agentic search capabilities, it can browse, hop links, and process media at speed. Validated by Artificial Analysis, Grok 4 Fast holds one of the best efficiency scores in the AI landscape. This launch marks a major step toward democratizing advanced reasoning AI for everyone—from enterprises to everyday users.

Mistral Adds Vision & Performance Upgrades to Magistral

Mistral has rolled out Magistral Small 1.2 and Magistral Medium 1.2, refreshed upgrades to the earlier 1.1 series, now bringing stronger multimodal intelligence with a vision encoder that allows seamless processing of both text and images. These versions deliver a 15% uplift across demanding math and coding benchmarks such as AIME 24/25 and LiveCodeBench v5/v6, making them more capable for advanced problem-solving. Tool use has also been refined, with better integration for web search, code interpretation, and image generation, making workflows smoother and faster. Beyond technical gains, the updates focus on experience—responses are now clearer, more naturally written, and easier to follow, with improved tone and formatting. Developers can access Magistral Small 1.2 directly on Hugging Face, while both models are live on Le Chat and available via Mistral’s API using the endpoints magistral-small-2509 and magistral-medium-2509

SWE-Bench Pro: AI Benchmark for Complex Software Tasks

The Social Work Education Assessment Project (SWEAP) offers a comprehensive package of six assessment instruments designed to help undergraduate and graduate social work programs track student progress from admission through alumni status. Originally developed as BEAP in 1999 and rebranded as SWEAP in 2013, it aligns with the Council on Social Work Education (CSWE) accreditation standards, helping programs evaluate student competencies and program effectiveness. SWEAP tools measure key professional skills and knowledge, providing both quantitative evaluation and qualitative feedback, making it a trusted resource for over 500 programs nationally to meet accreditation and improve educational outcomes.

Paper of The Day

The paper introduces Reasoning Core, a scalable reinforcement learning environment for improving symbolic reasoning in large language models (LLMs). It focuses on core formal domains such as PDDL planning, first-order logic, grammar parsing, causal reasoning, and system equation solving, using procedural generation of problems with continuous difficulty control. Verification is done via external specialized tools, ensuring robust and verifiable training data. Initial evaluations show that even state-of-the-art models like GPT-5 find these tasks challenging, positioning Reasoning Core as a valuable resource to advance the reasoning capabilities of future LLMs.
