peakstone 0.1.4

A public, reproducible benchmark platform tracking the capability frontier of open models (coding, agentic, planning).

Peakstone

A public, reproducible benchmark platform for the capabilities of open models — from solving simple verifiable assignments to (eventually) iterating their way through complex, multi-machine projects. Community-run, community-authored, independently reproducible.

Tsunami "high-water-mark" stones record how far the wave reached. Peakstone records how far the open-model capability frontier has reached — permanent, reproducible markers ("set in stone") of a moving peak.

See PLAN.md for the full vision, architecture, and roadmap.

Status

Early. P1 (reproducible coding leaderboard) is in progress. What exists today:

• engine/ — the test harness: serves a model over an OpenAI-compatible API, runs a suite of verifiable challenges (deterministic tests), scores them, and (soon) emits a signed result bundle. Also supports LLM-judge grading, self-repair (--retries), a global-rules output contract (--agents-md), tool-calling/agentic/injection modes, and a planner eval. Ships the result-bundle JSON Schema (the reproducibility contract) + capability taxonomy as packaged data in engine/schema/, so a bare pip install can produce and validate bundles.

• challenges/ — the challenge corpus (spec.md + tests/ + reference/ per challenge). Part of the repo workspace, not the PyPI wheel; running the suite needs a checkout (set PEAKSTONE_REPO if the package and corpus live apart).

• serve/ — local model-serving helpers (run your own GGUF models to test).

• gateway/ — peakstone serve: a standing, llama-swap-style OpenAI-compatible gateway on one port. It picks (and hot-swaps) the backend llama-server from the model field of each request, so it doubles as a local OpenAI endpoint for everyday use — not just benchmarking. It also owns the benchmark job queue (sqlite-persisted), so the TUI/CLI are thin clients: runs survive quitting the dashboard.

• api/ — the submission/leaderboard API (FastAPI + Postgres) that runs on peakstone.ai. Validates signed result bundles, serves faceted leaderboards, and moderates the open challenge corpus. Deployed from this repo via Docker (see Running the server below); not part of the PyPI client.

• web/ — the Next.js leaderboard frontend.

Quickstart — run the engine against a local model

# 0. Sanity-check the suite itself (no model needed): reference solutions must all pass
python -m peakstone.engine.runner --reference --models reference

# 1. Serve a model over an OpenAI-compatible API (any engine works; helper for llama.cpp GGUFs):
./serve/serve.sh <model-name>          # see serve/models.toml for the local registry
# …or run the model gateway, which hot-swaps models per request (see "Model gateway" below):
peakstone serve                        # then add `--gateway http://localhost:12434` to step 2

# 2. Evaluate it
export PATH="$HOME/opt/node/bin:$PATH"   # JS/TS test runners need this Node
python -m peakstone.engine.runner --models <model-name>
python -m peakstone.engine.runner --models <model-name> --retries 2 --agents-md   # self-repair + output contract

Scoring: final = pass_rate for tests challenges; 0.7*pass_rate + 0.3*judge for both. Each run records full per-challenge transcripts and the model/environment metadata needed to reproduce it. See peakstone/engine/runner.py --help for filters (--lang, --type, --difficulty, --ids) and modes (judge, retries, agents-md, planner eval).

Offline test sandbox (Linux)

Each test runs offline, in a throwaway network namespace (loopback only). This keeps a solution that does real network I/O — e.g. a BigCodeBench task that wget/HTTP/FTPs past the test's mocks — from hanging to the per-challenge timeout: the call fails fast instead.

It uses unprivileged user namespaces, which Ubuntu's AppArmor disables by default. Enable them:

sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0          # this boot
echo 'kernel.apparmor_restrict_unprivileged_userns=0' | sudo tee /etc/sysctl.d/99-peakstone.conf   # persist
# older kernels: kernel.unprivileged_userns_clone=1

Without it the harness still works — it just falls back to a plain subprocess (no network isolation), so a runaway network call can burn the full challenge timeout. Verify it's active: unshare -rn -- true should exit 0. (No-op on macOS, which mocks-or-Docker-isolates instead.)

Running on macOS (Apple Silicon)

The harness, dashboard, and serving all run on macOS. The engine auto-detects the platform — hardware stats come from sysctl/ioreg/vm_stat (the dashboard shows the unified-memory GPU live), and it uses GNU time only when present. One-time toolchain setup:

# Work in an isolated venv — don't install into system / conda-base Python:
python -m venv ~/.peakstone/venv && source ~/.peakstone/venv/bin/activate

# Python: engine deps + the optional library-challenge references + the dashboard TUI
pip install jsonschema cryptography pytest numpy pandas pydantic networkx more-itertools \
            python-dateutil sortedcontainers "textual>=0.60" "huggingface_hub>=0.20"

# JS/TS challenges: install the jsenv libs, plus tsx + typescript on PATH (the TS runner needs them)
( cd peakstone/engine/jsenv && npm install )
npm install -g tsx typescript

# Serving (optional — only to run a model): a Metal build of llama.cpp
brew install llama.cpp        # serve.sh finds `llama-server` on PATH automatically

On Apple Silicon, memory is unified (weights + KV share system RAM), so pick a model that fits your RAM with headroom — on a 16 GB Mac, vibethinker-3b (3.3 GB) or phi-4-mini (~9 GB) rather than the 22 GB roster tuned for a 24 GB NVIDIA card.

For the multi-machine agentic env challenges, the local provider works everywhere, and the docker provider gives full isolation plus network shaping (tc latency / iptables link partitions) on macOS too — those run inside Docker Desktop's Linux VM, so start Docker Desktop and use --env-provider docker. Only firecracker is genuinely Linux-only (it needs /dev/kvm, which Apple Silicon does not provide).

Dashboard (TUI)

A Textual terminal UI shows your local GPU/CPU/RAM live, next to the leaderboard filtered to what fits your hardware — so you can see how models that actually run on your machine compare:

Install into an isolated environment so Peakstone's dependencies never touch your system or conda-base Python (they'd otherwise clobber whatever requests/urllib3/etc. you already have):

pipx install peakstone                        # recommended — pipx gives it its own venv + a PATH shim
# …or a plain venv:
python -m venv ~/.peakstone/venv && ~/.peakstone/venv/bin/pip install peakstone

peakstone                                     # talks to the public API (https://peakstone.ai/api) by default
peakstone login                               # link your signing key to GitHub (one browser round-trip)
# self-hosting? point at your own server with --api http://localhost:8000 (or $PEAKSTONE_API_URL)

peakstone corpus sync                         # fetch the challenge corpus from GitHub (native + HumanEval + BigCodeBench + GSM8K)
peakstone-bench --level standard --models <your-model>   # run the official self-contained suite

The standard suite is fully self-contained (permissively-licensed content only). The heavier deep/max levels additionally reference copyright-encumbered imports (Codeforces/LiveCodeBench/ AIME/SWE-bench) that you regenerate locally via python -m peakstone.engine.importers.<name> and use under the upstream terms — they are never committed or published.

peakstone login binds your local ed25519 signing key to a GitHub handle: it opens the OAuth consent page, catches the redirect on a loopback callback, and proves key ownership by signing a server nonce — the private key never leaves your machine. Optional, but it attributes your runs and lets your reproductions count toward the community-verified (ranked) tier.

The published package is the client: the engine and the dashboard, nothing server-side. The submission API (api/) is the server and is deployed from this repo, never installed from PyPI — see Running the server below.

See peakstone/dashboard/README.md.

Model gateway (peakstone serve)

A standing, llama-swap-style OpenAI-compatible gateway on a single port (default :12434). The model field of each request selects the backend — the gateway loads/swaps the right llama-server on demand — so it's a drop-in local OpenAI endpoint for editors, scripts, and agents, and the serving layer the benchmark harness runs on.

peakstone serve                              # foreground; or `peakstone serve --detach`
# point any OpenAI client at it:
curl http://localhost:12434/v1/chat/completions \
  -d '{"model": "<model-name>", "messages": [{"role":"user","content":"hi"}]}'

Browser chat UI. The gateway also serves a single-file chat app at http://localhost:12434/chat (root / redirects there). It's a multi-conversation UI with editable system prompts, image input, streaming + reasoning, and a model selector populated live from GET /v1/models — picking a model just puts its name in the request body, so the gateway loads/swaps it into VRAM on demand. Because it's served from the gateway origin it shares /v1 (no CORS) and is reachable on the LAN at the gateway's host:port. On a trusted network, peakstone serve --host 0.0.0.0 --open drops auth so any device can use it tokenlessly; otherwise paste the token into the chat's ⚙ Settings (see auth below).

The gateway also owns the benchmark job queue (persisted to results/jobs.db), so the TUI/CLI are thin clients over it — runs keep going after you quit the dashboard, and reconnecting shows their state. Drive it headless with the jobs CLI:

peakstone jobs add <model-name> --level standard   # queue a run on the daemon
peakstone jobs list                                # queued / running / done
peakstone jobs logs <id>                            # stream a job's log
peakstone jobs cancel <id>

peakstone (the TUI) auto-spawns the gateway detached on startup; disable with --no-gateway or PEAKSTONE_NO_GATEWAY=1. Config lives under [gateway] in peakstone/engine/config.toml (host/port/idle_timeout_s — unload the model and free VRAM after a quiet spell; 0 = never).

Use it from another machine (auth). Loopback requests (127.0.0.1) need no token, so the TUI, the CLI, and anything on the box just work. To reach it over a LAN — e.g. an editor on your laptop driving the GPU box — bind it publicly and present the token; non-loopback requests without a valid one get 401:

peakstone serve --host 0.0.0.0          # prints the token; also saved to ~/.peakstone/gateway_token (0600)
# from the laptop — OpenAI base URL http://<gpu-box>:12434/v1, API key = that token:
curl http://<gpu-box>:12434/v1/chat/completions \
  -H "Authorization: Bearer $TOKEN" \
  -d '{"model": "<model-name>", "messages": [{"role":"user","content":"hi"}]}'

The token is generated on first run; override it with PEAKSTONE_GATEWAY_TOKEN. On a trusted LAN you can skip tokens entirely with peakstone serve --host 0.0.0.0 --open (auth disabled — any reachable device can drive the GPU, so use it only at home).

Sharing one GPU. Only one model is resident at a time. While a benchmark job runs it pins the GPU to that model: chat requests for the same model are served, but a request for a different model gets 503 busy rather than evicting the run mid-flight. With no job running, any model loads/swaps on demand.

Running the server (peakstone.ai)

The website + leaderboard API + Postgres + automatic-HTTPS proxy run as one Docker stack (infra/). Caddy serves the Next.js site at / and the API under /api/* on the same domain (so https://<domain>/ is the leaderboard and https://<domain>/api/... is the API). On a Linux box reachable on a public IP:

git clone https://github.com/peakstone-ai/peakstone && cd peakstone
cp infra/.env.example infra/.env        # set PEAKSTONE_DOMAIN + a strong POSTGRES_PASSWORD
./infra/deploy.sh                        # build, migrate (alembic), start db + api + web + caddy

Caddy provisions and renews the TLS cert for PEAKSTONE_DOMAIN automatically — point its DNS A record at the box and open ports 80 + 443; there's no certbot to manage. To update: git pull && ./infra/deploy.sh. Migrations (alembic upgrade head) run on every deploy before the app starts. Postgres is internal-only (not published to the host); only the proxy is exposed. For a local self-signed smoke test, leave PEAKSTONE_DOMAIN=localhost and run docker compose -f infra/docker-compose.yml up --build.

Running the API directly (dev / LAN). Outside Docker, python -m peakstone.api starts uvicorn with host/port from the [api] block in engine/config.toml. It's local-only by default; to reach it from your phone or another machine on the LAN, expose it without editing the tracked config by dropping this in ~/.peakstone/config.toml (or pass --host 0.0.0.0, or set PEAKSTONE_API_HOST=0.0.0.0):

[api]
host = "0.0.0.0"

Ingest is signature-verified, but account/admin endpoints are reachable too — only bind 0.0.0.0 on a trusted network.

Add a challenge

Create challenges/<lang-or-category>/NN-slug/ with meta.toml, spec.md, tests/, and a reference/ solution, then verify it passes its own tests:

python -m peakstone.engine.runner --reference --models reference --ids <id>

See CONTRIBUTING.md for the challenge schema, the corpus → admin-canonized suite lifecycle, and the DCO sign-off. Several challenges test library fluency with offline-safe libs (Python: numpy/pandas/pydantic/networkx/...; JS/TS: lodash/date-fns/zod/mathjs in peakstone/engine/jsenv).
