Query model scores and test AI APIs before you choose

Use the model search on the homepage or open the Model Performance leaderboard. Search by model name to find the model detail page, where LMSpeed connects benchmark signals such as AA score, coding, and math with model metadata.

LMSpeed aggregates per-token pricing from 100+ API providers. Visit any model page to see a side-by-side pricing comparison table showing input and output rates per million tokens, so you can find the cheapest provider for each model.

Many providers offer free API tiers or credits for popular models like DeepSeek, Gemini, and Llama. Check our Free LLM API directory for a complete list of models with free access, including speed benchmarks for each free provider.

LMSpeed employs a five-round continuous stress testing mechanism with standardized prompts. Token calculations are performed accurately using tiktoken, measuring output throughput (tokens per second) and first-token latency.

It sends multiple safety probes to an OpenAI-compatible endpoint to check whether the model identity matches, hidden system prompts are injected, user instructions are rewritten, streaming responses stay intact, and errors leak sensitive implementation details. The result includes a risk score and a shareable report. API keys are only used for that audit and are not written to public reports.

Use our performance leaderboards and model detail pages to visually compare API speed benchmarks across providers. The system ranks providers by throughput, latency, and health, helping you choose the fastest and most reliable API.

Provider pages and the health leaderboard already show recent health checks, probe latency, success or failure status, and stability rankings. Broader continuous monitoring and alerting will keep expanding.
