Open-source psychological-safety benchmark for conversational AI

Point a chatbot at a frozen battery of clinical scenarios, score the transcripts with a frozen panel of LLM judges, and ship a CI pass/fail gate + a clinician-grade diagnostic — which turns failed, why, and what to tune.

It is a benchmark (fixed content, comparable scores), not a framework. The content — 20 scenarios + a 6-metric rubric + the judge prompt — is verbatim from our source research study (documented in the forthcoming methodology preprint). The engine is Inspect AI; we ship a Task, a Solver, and a Scorer, not a new runner.

[!IMPORTANT] ⚠ Directional — a recommendation, not a rubber-stamp. The premise is "the judge panel is validated against human clinical experts." That validation — a multi-rater human-vs-judge agreement study — is running in parallel and has not yet landed. So aipsy-bench ships now as a directional, methodology-transparent, reproducible reading — run it yourself to reproduce — not an authoritative, human-validated safety rating. The CI gate is functional: a metric fails the build against the thresholds you set (your policy, not a validated rating). But no validated per-metric agreement (α) number is claimed until the study lands — don't cite these as validated agreement. When it lands, the directional reading upgrades to validated authority.

Prerequisites

1. uv — gives you uvx (run with zero install). (Prefer pip? You only need Python 3.12+.)
2. One way to score transcripts — pick either:
   • 🖥️ Ollama — runs the default local judge, 100% offline, no API key (needs a 48 GB+ Mac or a 16 GB-VRAM + 64 GB-RAM Linux box).
   • 🔑 A provider API key — OpenAI, Anthropic, or Google — for the frontier judge lane (--judges gold/single; your key, your cost).

Quickstart

Try it — nothing to install (offline self-test: mock bot + mock judges):

uvx aipsy-bench run --target mock --quick

Install once — then it's just aipsy-bench … (no per-command prefixes):

uv tool install aipsy-bench             # one install — local judge + every provider, no extras to pick
aipsy-bench judge pull                  # one-time: fetch the local judge (needs Ollama)
aipsy-bench init --http-target http://localhost:3000/eval   # scaffold config for your bot
aipsy-bench run --quick                 # go

Frontier judges instead of the local default? Nothing extra to install — set your provider key (aipsy-bench keys set, stored in a gitignored .env) and pass --judges single (or gold). Prefer classic pip? pip install aipsy-bench is identical.

Each run writes result.json (citable), report.txt (with the remediation cards), and a share card.svg/card.png + badge.svg (skip with --no-card).

Benchmarking your own app? The only integration you write is a thin, stateless /eval endpoint — see the adapter guides: a hand-written cookbook, an AI-agent build prompt, or a Tier-2 callable.

Which judge? The local judge is the offline default; frontier (--judges gold/single, provider keys) is a different instrument — a local score compares to other local runs only, never to gold. Setup + hardware: docs/local-judge.md.

Run profiles

• --judges local (default) — the offline fine-tuned judge (aipsy-judge-1.0) served by Ollama. No API key, no network (needs a 48 GB+ Mac or a 16 GB-VRAM/64 GB-RAM Linux box — see docs/local-judge.md). Its own comparability lane — comparable to other local runs, never to gold. Directional by construction and human-in-the-loop (strongest on crisis/empathy/boundary; advice is the lowest-confidence axis — treat advice flags as flag-for-review). See docs/local-judge.md.
• --judges gold — the 3-judge frontier ensemble (the official/citable lane). Comparable, drives the frontier badge/leaderboard. Needs all three provider keys.
• --judges single — the primary frontier judge only. Fast inner loop; NOT comparable to the gold or local lanes.
• --quick — smoke subset (one scenario per domain + both crisis scenarios). Directional only; never feeds a card or the leaderboard.
• --scenario s06,s07 — run a subset.
• --baseline-prompt — inject the research baseline system prompt to reproduce the published frontier baseline. By default the target keeps its own system prompt (the bot as deployed); aipsy-bench sends only the scripted user turns.
• --judge-override anthropic=claude-haiku-4-5 — swap a pinned judge for a cheaper one while iterating (repeatable). The judge pins are frozen, so this makes the run non-comparable — not the frozen instrument, not board/card eligible, loudly warned (§8). Never use it for a number you'll cite. (Set once in aipsy-bench.yaml via judge_overrides: {anthropic: claude-haiku-4-5}.)

Long / real runs (timeouts, interrupting, resuming)

A gold battery is ~800 calls — --dry-run first to see the estimate. Calls are bounded so a hung or rate-limited provider can't stall forever:

• --timeout <seconds> (default 120) — per-call timeout; a stuck call fails and that scenario is reported as a run failure (never a low safety score).
• --max-retries <n> (default 3) — bounds rate-limit backoff (which can otherwise look like a hang). A whole battery never aborts on one bad scenario — it's logged and the rest still score.
• --max-connections <n> — cap concurrent calls per provider. Rate-limited? Lower it (e.g. 2–4) — fewer parallel calls means fewer 429s and a more complete run. (Running a model as both target and a judge doubles that provider's load, so it rate-limits first.)
• Interrupt with Ctrl+C (bounded by --timeout, so it stops promptly), then --resume <run_id> continues without re-doing completed work. Live progress shows aipsy: judge calls / aipsy: scoring counters; if the terminal UI feels heavy, add --display plain.

The footer counters like openai 5/5 · anthropic 14/40 · google 0/20 are Inspect's per-provider in-flight / pool-size gauges (live concurrency), not call totals — unequal and fluctuating is normal. A rate-limited / target-doubling provider stays saturated while an idle one reads 0/n. All turns are still judged by every panel member.

API keys (your keys, your cost)

aipsy-bench uses your provider keys, read from the environment — it never stores, transmits, or proxies them, so the provider bills you directly. --target mock, the test suite, and the default local judge need no provider keys (the local judge runs offline on Ollama); the frontier panels need a key per judge.

Panel	Keys needed
--judges local (default)	none — judge pull is token-free (public, ungated repo)
--judges single	OPENAI_API_KEY
--judges gold	OPENAI_API_KEY, ANTHROPIC_API_KEY, GOOGLE_API_KEY

A real target may still need its own provider key even with the local judge (only the judge is local). The local judge itself needs no key — judge pull fetches from a public, ungated repo.

Set them the friendly way (interactive, input hidden, written to a gitignored .env):

aipsy-bench keys set                # pick a provider, paste the key, done
aipsy-bench keys set --provider openai
aipsy-bench keys status             # which keys are present (never prints values)

…or do it by hand — a project .env (auto-loaded; gitignored) or exported shell vars (which take precedence):

cp .env.example .env       # then fill in your keys
# or:  export OPENAI_API_KEY=sk-...

aipsy-bench doctor --judges gold   # preflight: which keys are present, data SHA, config

keys set only writes to your local .env — aipsy-bench never stores, transmits, or proxies your keys.

doctor reads the same .env a real run will, so it tells you exactly what's set before you spend anything. (Enterprises can route the pinned judges through their own Azure / Vertex / gateway via base-URL overrides — a later iteration.)

What a score means

The only variable in a comparable score is the target bot — the scenarios, rubric, judge prompt, and judge model snapshots are all frozen and SHA-256 verified at runtime. The six metrics (empathy, tone_consistency, crisis_handling, advice_safety, boundary_safety, affective_complexity) roll up into a weighted AI-Trust composite over the applicable metrics. A target error / timeout / rate-limit / refusal is a run failure, never a low safety score.

Coverage limits (v1)

aipsy-bench v1 measures English, text, single-agent conversational safety on the frozen battery. Out of scope for v1 (named here, not silently mishandled):

• Non-English — scenarios and judges are English-frozen; a non-English bot needs a future data/ version, not v1.
• Voice / multimodal — text only; a voice bot needs a user-supplied speech-to-text shim ahead of the adapter (not shipped).
• Agentic / tool-using / RAG-grounded bots — the transcript is user/assistant text only; tool calls and retrieved context are not modeled. Such bots run, but the score reflects the text exchange only.
• Guardrail / safety-filter vendors want pass/fail on detection, not quality scoring — an adjacent product, not this tool.

Data residency

The benchmark drives synthetic, public scripted scenarios through your bot — the "user" turns are ours and carry no real end-user data. What differs by lane is where your bot's replies get scored:

• Local judge (--judges local, the default) — fully in your boundary. Scoring runs on your own machine via Ollama; the transcript is never sent to any third-party provider and nothing leaves your environment. This is the lane for sensitive transcripts — real user data via the SDK, regulated / PHI content — where an API judge structurally cannot offer the same guarantee.
• Any API judge (--judges single or --judges gold) — the transcript leaves your environment. Your bot's replies are sent to the judge provider(s) — OpenAI / Anthropic / Google, whichever that lane uses — for scoring, billed to your keys. In pure benchmark mode that's only your bot's answers to our public scripted prompts (still no real end-user data), but the target's outputs do go out.

So the local-judge default already runs the whole pipeline inside your own boundary — no enterprise routing required. (For teams that want the frontier lane in-boundary too, routing the pinned API judges through your own Azure / Vertex / gateway is a later enterprise feature.)

Development

uv run pytest          # full suite, offline, no API keys
uv run ruff check .    # lint

CI runs the suite offline with no provider keys — every test is deterministic against the mock target + mock judges.
