Petabyte CLI & Dashboard

CLI

Installed from PyPI, the petabyte command is a thin client (only needs httpx — it just talks to the API over HTTPS, so it never pulls in the server):

pip install petabyte-client                          # the command it installs is `petabyte`
export PETABYTE_API_URL=https://petabyte.market     # default; or pass --api / omit for localhost
petabyte register -u alice -p secret
petabyte login    -u alice -p secret
petabyte deposit 100
petabyte specs                                       # a readable, cheapest-first GPU table
petabyte launch ollama --hours 2                     # one-click app: cheapest verified GPU, started
petabyte run hello.ipynb --gpu H100 --hours 1        # run a notebook/.py on a rented GPU
petabyte ask "explain attention" --model llama3.2    # pay-per-token Inference API (OpenAI-compatible)
petabyte wallet

petabyte ask uses an inference-scoped API key — pass --key, set PETABYTE_API_KEY, or save it as api_key in your CLI config; the answer prints to stdout (the token/cost line to stderr). Model management is included — petabyte pull <publisher/model>, petabyte model list/inspect/remove, and petabyte run <model-id> work straight from the pip install (the model hub is pure standard library, so it adds no dependency beyond httpx):

petabyte pull Qwen/Qwen3-8B          # verified, resumable download into ~/.petabyte
petabyte model list                  # what's in your local cache
petabyte run Qwen/Qwen3-8B           # start a model runtime

The package is built from the repo-root pyproject.toml (name = "petabyte-client"; the command stays petabyte), which bundles this CLI module plus the modelhub package. From a source checkout you can also run it directly with python cli/petabyte.py <cmd>, or pip install . from the repo root. run books the cheapest matching GPU, escrows funds, dispatches the notebook, polls, and prints the result. .ipynb (code cells) and .py files are supported.

Output & config

• Human output: semantic colour (green=ok, yellow=pending, red=error, cyan=info) with aligned tables. Colour turns off automatically when stdout is not a TTY or NO_COLOR is set — safe for scripts and CI. The buyer petabyte client uses its own small inline colour helpers (no dependency beyond httpx); it does not import cli_ui.py.
• PETABYTE_API_URL (or --api) selects the API; PETABYTE_CONFIG=/path/cli.json isolates the saved token/API (handy in CI or tests).

Note: a stable --json/PETABYTE_JSON machine-readable mode and a doctor health-gate command exist in the seller agent CLI (lumaris_agent/agent_cli.py), not in this buyer client. The shared cli_ui.py presentation layer is likewise used by the agent and desktop app, not by petabyte.py.

Dashboard

Served by the API at / (same-origin, no CORS setup). Start the API and open http://localhost:8000/ — live nodes/jobs/GMV stats, wallet + deposit, the GPU inventory with a live $/hr-vs-AWS savings column, and one-click job runs.

Both need an attested, online seller node (run the agent) to actually execute jobs.
