FastAPI server for streaming promptuna run / evaluate / optimize jobs
Project description
promptuna-server
Server surface for the
promptunaevaluation harness. See the main project README for the full overview, library API, and usage surfaces.
HTTP + SSE transport for promptuna jobs (run, evaluate, optimize).
This package is transport only. It does not define evaluation logic — that lives in the core promptuna library. On-disk projects are resolved via promptuna.projects; user projects do not belong in this directory.
Development
From the repository root:
just server
Uses bundled samples/ by default. Override the projects root:
PROMPTUNA_PROJECTS_ROOT=/path/to/projects just server
API listens on port 6969. Job progress streams at GET /jobs/{job_id}/events (SSE).
Completed jobs are persisted under <projects_root>/jobs/<job_id>/ as manifest.json, append-only events.jsonl, and a terminal summary.json.
GET /catalog lists project and artifact names under the active projects root so clients can build job selectors. The response includes projects_root plus, for each project, name lists for programs, metrics, prompts, and datasets.
A future promptuna serve command will wrap uvicorn and accept --projects-root explicitly.
