Browser-tools-mcp and other methods for agentic browser use

The trajectory of AI has shifted from static text generation to dynamic, agentic execution. In this new paradigm, the web browser represents one of the most important interfaces for AI agents - serving as the gateway to information, SaaS applications, and digital workflows. But integrating large language models with browser

AI contextual refinement

Understanding AI contextual refinement has become essential as technology shifts from focusing solely on prompt engineering to embracing context engineering. As AI models advance, the skill of contextual refinement becomes crucial to optimize outputs, increase accuracy, and reduce hallucinations. Effective context management in LLMs is now critical for higher efficiency

LLM-as-a-Judge: Using AI Models to Evaluate AI Outputs

Evaluating AI-generated text remains a significant challenge. Traditional metrics often fail when dealing with open-ended tasks. And while human evaluation is considered the gold standard, it's often slow, costly, and hard to scale. Enter the concept of "LLM-as-a-Judge," a novel approach where large language models (LLMs)

Capabilities, Pricing, and Integration Risks: x-ai/grok-4-fast:free

In the ever-evolving world of AI, the concept of "free" draws considerable attention, especially when it involves models like x-ai/grok-4-fast. This entry into the AI landscape offers significant AI access functionalities. Designed by xAI, and available via OpenRouter, Grok 4 Fast represents a shift towards more affordable

LLM Evaluation Fundamentals: Our Guide for Engineering Teams

Moving from the realm of traditional software testing to evaluating LLMs presents a unique set of challenges and opportunities for modern engineering teams. Below, we delve into the nuanced world of LLM evaluation, exploring the best practices, common obstacles, and effective techniques that are shaping the landscape today. Why evaluating
