Skill / MCP: use leaderboard data in your agent

Agent skill (SKILL.md)

Save this file as SKILL.md inside a skills folder and your agent will know how to read the leaderboards and the model capability comparison through the public API.

name: pandanpc-leaderboard
description: Look up current AI model leaderboards and the top-10 model capability comparison from PandaNpc's public API. Use when the user asks which AI model is best, how models rank on chat, coding, image, video, speech or agent tasks, or how top models compare on benchmarks.

# PandaNpc leaderboard

Public, read-only JSON API. No account and no API key. Base URL: https://api.pandanpc.com/api/public/leaderboard

## Boards

GET https://api.pandanpc.com/api/public/leaderboard
GET https://api.pandanpc.com/api/public/leaderboard?category=<board key>

Response: { boards: [{ key, source, metric, meta, rows }], vendorIcons }
- With ?category=<key> the response still contains every board, but only the requested one has rows; boards with an empty rows array are shells. Always pick a board by key (for example jq '.boards[] | select(.key=="llm_chat")'), never by index.
- key: llm_chat, image_gen, code, image_edit, video, agent, vision, search, document, image_to_video, video_edit, text_to_speech, speech_to_text, speech_to_speech, or_usage, aa_intelligence
- source: arena | artificial_analysis | openrouter
- meta: { source_url, last_updated, synced_at }
- rows: [{ rank, model, vendor, score, ci, votes, ...price fields }]

Scores are comparable only inside one board. Arena boards are Elo from human blind votes; read the rank together with ci. Lower is better for speech-to-text (word error rate).

## Capability comparison

GET https://api.pandanpc.com/api/public/leaderboard/capabilities

Response: { dimensions, models, sources, fetched_at }
- models: top 10 by Epoch Capabilities Index: { rank, model, model_key, vendor, eci }
- sources: [{ source, label, license, url, updated, fetched_at, boards }] including epoch, vals, aa, google_card, browserbase, browser_use, coarena and ale
- boards: [{ key, name, capability, comparison_key, updated, fetched_at, scores }] where scores is keyed by model_key: { score, score_raw, scale, effort, harness, cost_per_task, model_version, evaluation_metadata }

Preserve every published configuration. Compare only within one source and comparison_key. Read scale: percent is 0-100, rating (Coarena) is not a percentage. Coarena is mixed-task blind human preference; show its 95% interval. ALE allows GUI/CLI tools; keep its full/max configuration, harness and run-task / split-task counts, and separate pass rate from partial score. updated is the upstream date when published; fetched_at is PandaNpc's fetch time, never a substitute source date.

## Attribution (required)

Name the source next to any number you show:
- Epoch AI, CC BY 4.0 (epoch.ai)
- Vals.ai (vals.ai)
- Artificial Analysis (artificialanalysis.ai)
- Coarena (coarena.ai) and Agents’ Last Exam, CC BY 4.0 (agents-last-exam.org), for their matching sources
- arena.ai and OpenRouter for the matching boards

Data refreshes about once a day. Cache for at least an hour.

MCP server

Add the PandaNpc MCP server to your client with this configuration, or run the command below.

{
  "mcpServers": {
    "pandanpc": {
      "command": "npx",
      "args": ["-y", "@pandanpc/mcp-server"]
    }
  }
}

claude mcp add pandanpc -- npx -y @pandanpc/mcp-server

The MCP server does not expose leaderboard tools yet. For leaderboard data use the skill above or the REST API below.

curl examples

# All boards (Arena, Artificial Analysis, OpenRouter) in one response
curl -s https://api.pandanpc.com/api/public/leaderboard

# One board: add ?category=<board key>, e.g. llm_chat, code, image_gen, aa_intelligence
# The response still lists every board, but only the requested one has rows (the others are empty shells)
curl -s "https://api.pandanpc.com/api/public/leaderboard?category=llm_chat"

# Top 5 models of the chat board: select the board by its key, never by position
curl -s "https://api.pandanpc.com/api/public/leaderboard?category=llm_chat" | jq '.boards[] | select(.key=="llm_chat") | .rows[:5] | map({rank, model, vendor, score})'

# Capability comparison: top 10 models by Epoch Capabilities Index x benchmarks
curl -s https://api.pandanpc.com/api/public/leaderboard/capabilities

# GPQA Diamond score of every model (Epoch AI)
curl -s https://api.pandanpc.com/api/public/leaderboard/capabilities | jq '.sources[] | select(.source=="epoch") | .boards[] | select(.key=="gpqa_diamond") | .scores'
