How The Index is Built
Each benchmark becomes a 0-100 standing, and the index is the weighted average of those standings. A benchmark a model has not been run on counts as the field average, so scores stay comparable. Index = Terminal-Bench-Science (14%) + FrontierMath (12%) + Frontier-Bench (12%) + ArxivMath (10%) + MMMU-Pro (9%) + ARC-AGI-2 (8%) + CritPt (6%) + FinanceReasoning (5%) + Text-to-SQL (5%) + BioMysteryBench (5%) + ARC-AGI-1 (5%) + Terminal-Bench 2.1 (3%) + Agentic RAG (3%) + Terminal-Bench Hard (2%) + LegalBench (1%).

Large Multimodal Models (LMMs) vs LLMs
We evaluated the performance of Large Multimodal Models (LMMs) in financial reasoning tasks using a carefully selected dataset. By analyzing a subset of high-quality financial samples, we assess the models’ capabilities in processing and reasoning with multimodal data in the financial domain. The methodology section provides detailed insights into the dataset and evaluation framework employed.…
LLM Scaling Laws: Analysis from AI Researchers
Large language models predict the next token based on patterns learned from text data. The term LLM scaling laws refers to empirical regularities that link model performance to the amount of compute, training data, and model parameters used during training. To understand how these relationships influence modern model design in practice, we reviewed findings from…
LLM Observability Tools: Weights & Biases, Langsmith
LLM applications have expanded from single-turn chats into multi-step agents that use tools, query databases, and coordinate with other models, making their behavior harder to interpret. LLM observability provides continuous visibility into these complex workflows, helping organizations monitor quality, detect failures, troubleshoot issues, and manage performance and costs. W&B Weave is Weights & Biases‘ LLM…
Cloud LLM vs Local LLMs: Examples & Benefits
Cloud LLMs, powered by advanced models like GPT-5.5 and Claude Opus 4.7, offer scalability and accessibility. Conversely, Local LLMs, driven by open-source models such as Llama 4, DeepSeek V4, and Qwen3.6-Plus, ensure stronger privacy and customization. Explore what are cloud LLMs, strengths and weaknesses, most common case studies with real-life examples, and how they differ…
Audience Simulation: Can LLMs Predict Human Behavior?
In marketing, evaluating how accurately LLMs predict human behavior is crucial for assessing their effectiveness in anticipating audience needs and recognizing the risks of misalignment, ineffective communication, or unintended influence. Audience simulation with LLMs enables the modeling of virtual audiences, helping organizations anticipate reactions to content or products without relying on costly surveys or focus…
LLM Fine-Tuning Guide for Enterprises
Follow the links for the specific solutions to your LLM output challenges. If your LLM: The widespread adoption of large language models (LLMs) has improved our ability to process human language. However, their generic training often results in suboptimal performance for specific tasks. To overcome this limitation, fine-tuning methods are employed to tailor LLMs to…
LLM Market Share: Compare Usage & Adoption
We analyzed LLM market share by combining usage-based data and web visit estimates to show how demand for large language models is distributed across AI labs and AI applications: Read the methodology to see how we measured and calculated these results. The United States dominated web visits across all four months, consistently accounting for 85–95%.…
10+ Large Language Model Examples
We have gathered open-source benchmarks to compare leading proprietary and open-source large language models. Choose your use case to find the right model. You can evaluate large language models by examining their benchmark performance and real-world latency (available by clicking each model’s name in the table), and by reviewing their pricing to assess overall efficiency…
LLM VRAM Calculator for Self-Hosting
Self-hosting an LLM means running inference on hardware the operator controls rather than via a third-party API, which changes the cost, data control, and privacy profile. Whether a model runs at all depends on memory. The calculator estimates the VRAM or unified memory a model needs to run locally, based on the model, its precision,…
LLM Pricing: Top 15+ Providers Compared
LLM pricing spans four orders of magnitude: the cheapest models launched under $0.03 per million tokens, while frontier reasoning tiers launched at up to $262.50. The chart below tracks launch prices: each point is the average price of the models one size class launched in a calendar quarter, blended 3 parts input to 1 part…
