What it does
Test ~100 AI models against YOUR specific prompts. Get deterministic scores, real API costs, and stability metrics. Built this after discovering the "best" model for my RAG pipeline was a model that performed better AND cost 10x less. No LLM-as-judge. No voting. Just reproducible results for your actual use case. • 18 scoring modes • Real cost/efficiency calculations from API pricing • Vision & document support • Beginner-friendly yet capable of deep, complex use. Free tier available
Compare AI model pricing and performance. Benchmark 100+ LLMs including GPT, Claude, Gemini on your actual task. Deterministic scoring, real API costs.
OpenMark helps you evaluate AI models with custom benchmarks. Here's the flow: An AI model's ranking on popular leaderboards tells you little about how it'll handle your specific needs. The only way to know is to test your actual use case. AI providers update models silently. A model that worked perfectly last month might behave differently today. Regular benchmarking catches drift before it becomes a production issue. When a shiny new model drops, don't assume it's an upgrade for your task. New models often excel in some areas while regressing in others. Test before you switch. Premium "reasoning" models shine on complex tasks, but simpler models often win on straightforward ones, at a…from openmark.ai

- EFEcho – Fable-level results at 1/3 the cost using open-weight modelsJul 2026 · ▲484
I’ve been building Echo (https://echo.tracerml.ai/), an experiment in making one AI system out of a pool of open-weight models rather than choosing a single model and using it for every task. It started with a simple experiment. I took a group of models, including GLM-5.2, Kimi K2.7 and others, and ran them on the same evaluations. Then I measured what would happen if, for each problem, you somehow knew in advance which models would be useful and how their outputs should be combined. That hypothetical system performed substantially better than any individual model in the pool.…
LLM StatsOct 2025 · llm-stats.com · ▲293I was overspending on GPT-4o. It was really hard to compare different models I could switch to, so I built this LLM comparison tool. It shows leaderboards, pricing, and performance data across 100+ LLMs (including all major providers and open-source models). Key features: - Live pricing comparisons - Benchmark Scores (MMLU, HumanEval, GPQA, etc.) - Context length vs cost analysis - Speed/throughput tests across providers - Quality vs price visualizations - Open source (all data verifiable) Try it out: https://llmstats.com I'd like to know your opinion :) Tech stack: Next.js,…
- ATA tool to benchmark LLM APIs (OpenAI, Claude, local/self-hosted)2025 · llmapitest.com · ▲55
I recently built a small open-source tool to benchmark different LLM API endpoints — including OpenAI, Claude, and self-hosted models (like llama.cpp). It runs a configurable number of test requests and reports two key metrics: • First-token latency (ms): How long it takes for the first token to appear • Output speed (tokens/sec): Overall output fluency Demo: https://llmapitest.com/ Code: https://github.com/qjr87/llm-api-test The goal is to provide a simple, visual, and reproducible way to evaluate performance across different LLM providers, including…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
