Live scoreboard for inference economics

Live leaderboard / honest source labels active

Inference economics for teams shipping at the edge of latency budgets

See which AI inference providers are actually winning on speed, price, and sustained throughput.

InferenceIndex is a benchmark front-end for evaluating provider tradeoffs before they become incident review material. The leaderboard reads from Postgres, refreshes hourly, and marks speed metrics pending unless they came from authenticated inference runs.

Provider leaderboard

Compare inference vendors at a glance.

Public catalog probes only confirm provider docs are reachable. Latency, throughput, and composite score are published only from authenticated streaming inference runs; otherwise they stay marked as pending.

Method note: Speed cells show N/A until the collector can run a real completion with provider API keys. Pricing is documented provider list pricing for the tracked model, not a measured runtime metric.

Latency

P95 response time under real application load

Teams reach for the fastest endpoints when user-visible interactions start to stack.

Cost

Price pressure normalized per 1M output tokens

Cost curves matter most when volume spikes and routing policies need immediate tradeoffs.

Throughput

Tokens per second that survive concurrency

Burst handling decides whether a provider belongs in the hot path or the fallback pool.

FAQ

Common questions about AI inference provider comparison

These are the questions developers search when they need a live LLM benchmark leaderboard, clearer API pricing comparisons, and faster signal on which provider belongs in production.

Which LLM API is fastest?

A fastest-provider claim is pending until authenticated inference runs are available. InferenceIndex still shows documented pricing, but marks latency and throughput as N/A rather than using catalog-response timings as fake benchmarks.

What is the cheapest LLM API in 2026?

OpenRouter is currently the lowest-cost provider in the InferenceIndex dataset, but the cheapest LLM API in 2026 still depends on your prompt-output mix, model choice, and routing strategy. Benchmarking price alongside latency and throughput is the safest way to avoid optimizing for a misleading headline rate.

Groq vs Together AI vs OpenRouter: which one is best?

There is no single best provider across every workload. Teams usually compare Groq, Together AI, and OpenRouter on latency, model access, reliability, and blended token pricing, which is why InferenceIndex benchmarks OpenRouter, Groq, Together AI side by side instead of declaring one permanent winner.

How should developers compare AI inference providers?

Developers should compare AI inference providers on measured latency, tokens per second, normalized token pricing, available models, and consistency under load. If real inference measurements are unavailable, a trustworthy leaderboard should say so clearly instead of inventing speed numbers.

Is there a live LLM benchmark leaderboard for API pricing and latency?

Yes. InferenceIndex is a live LLM provider leaderboard built for developers who want a current AI inference comparison across speed, throughput, and price. The homepage is backed by rows stored in Postgres and refreshed on a schedule, with speed fields marked pending until real inference runs exist.
