Which Language Model
Should You Use?
Compare GPT-4, Claude, Llama, Mistral, and other LLMs across standard benchmarks. From language understanding (MMLU) to mathematical reasoning (GSM8K, MATH) to code generation (HumanEval).
LLM Leaderboards Coming Soon
We're building comprehensive LLM benchmark tracking with verified results across MMLU, GSM8K, MATH, HumanEval, and more. Unlike marketing claims, we'll show you real performance with consistent evaluation protocols.
What Makes a Good Language Model?
LLMs are evaluated across multiple dimensions. No single benchmark tells the full story. Here's what we track:
General Knowledge
How well does the model understand the world? Tested via MMLU (57 academic subjects), ARC (science), and HellaSwag (common sense).
Reasoning Ability
Can the model think through complex problems? Measured via GSM8K (grade-school math), MATH (competition problems), and GPQA (expert reasoning).
Code Generation
Programming proficiency via HumanEval (function synthesis), MBPP (Python basics), and SWE-bench (real-world debugging).
Multimodal Understanding
Vision capabilities tested via MMMU (college-level reasoning), MathVista (visual math), and ChartQA (data interpretation).

Leaderboards Coming Soon
We're building detailed comparison tables showing how these models perform across MMLU, GSM8K, HumanEval, and other standard benchmarks. Unlike vendor-reported scores, we'll verify results from published papers and official leaderboards.
Understanding the Metrics
MMLU (Massive Multitask Language Understanding)
Multiple-choice questions across 57 subjects from elementary math to professional law. The most comprehensive test of general knowledge.
GSM8K (Grade School Math 8K)
8,500 grade-school level math word problems requiring multi-step reasoning. Tests basic mathematical reasoning ability.
HumanEval
164 Python programming problems. Model must generate a function that passes unit tests. The standard for measuring code generation ability.
GPQA (Graduate-Level Google-Proof Q&A)
Expert-written questions in biology, physics, and chemistry designed to be difficult even for domain experts. Tests deep reasoning.

Why Our LLM Benchmarks Will Be Different
Verified Results Only
No marketing claims. We cite published papers, official leaderboards, and third-party evaluations. Every number is traceable.
Consistent Methodology
Same evaluation protocol for all models. We note when vendors use different prompting strategies or few-shot examples.
Regular Updates
New models release weekly. We track the latest results as papers publish and maintain historical trends.
Frequently Asked Questions
What's the difference between GPT-4 and GPT-4o?
GPT-4o is the "omni" version with native multimodal capabilities (vision, audio). It's faster and cheaper than GPT-4 while maintaining similar benchmark scores on text tasks. GPT-4o is now the default model at OpenAI.
Are open-source LLMs competitive with GPT-4?
For many tasks, yes. Llama 3.3 70B achieves ~86% on MMLU and 85%+ on HumanEval, competitive with GPT-4. The gap is narrowing, especially in reasoning tasks. Trade-off: you host it yourself vs API convenience.
Why do benchmark scores vary across sources?
Different evaluation setups: 0-shot vs few-shot prompting, exact wording of system prompts, temperature settings, and whether chain-of-thought is used. We'll document these differences when we launch full leaderboards.
Which benchmark best predicts real-world performance?
Depends on your use case. For coding assistants, check SWE-bench. For tutoring/QA, MMLU matters. For math/analysis, GSM8K and MATH. No single metric captures everything. That's why we track multiple benchmarks.
Want updates when we launch LLM leaderboards?
