Ping major LLM providers in parallel and compare real API latency. Run with /ping

LLM Speedtest

Ping major LLM providers in parallel and compare real API latency (TTFT).

When to Use

• User types /ping or asks about model latency/speed
• Comparing provider response times
• Checking if a specific provider is slow or down

How It Works

Runs scripts/ping.sh which:

1. Retrieves API keys from pass shared/ (users may need to adapt key sourcing for their setup)
2. Fires parallel curl requests to each provider with a minimal prompt ("hi", max_tokens=1)
3. Measures total round-trip time per provider
4. Sorts results by latency and displays with color badges

Output Format

Results are sorted fastest-to-slowest with color badges:

• 🟢 < 2s — Fast
• 🟡 2–5s — Normal
• 🔴 5–30s — Slow
• ⚫ 30s — Timeout

Example:

⚡ Model Latency — 14:32

🟢 `Gemini       412ms`
🟢 `GPT-4o       623ms`
🟢 `Sonnet       891ms`
🟡 `Grok        2104ms`
🟡 `MiniMax     3210ms`
🟡 `Opus        4102ms`

Models Tested

Provider	Model
Anthropic	Claude Sonnet 4
Anthropic	Claude Opus 4
OpenAI	GPT-4o-mini
Google	Gemini 2.5 Flash
MiniMax	MiniMax-M1
xAI	Grok 3 Mini Fast

Cost

~$0.0001 per run (1 token per model, cheapest tiers).

Note

This skill uses pass shared/ for API key retrieval. If you don't use pass, you'll need to adapt scripts/ping.sh to source keys from environment variables or another secret manager.
