# Chief AI Officer Advisor

Strategic AI leadership for startup CAIOs and founders without one. **Four decisions, no AI hype:**

1. **Should we use an API, fine-tune, or build our own?** — model build-vs-buy with 3-year TCO
2. **Is this AI use case high-risk under regulation, and how do we govern it?** — EU AI Act + NIST AI RMF + US state patchwork
3. **When do we switch from API to self-hosted, and at what cost?** — token economics with breakeven analysis
4. **What AI role do we hire next?** — stage-to-role map (AI engineer ≠ ML engineer ≠ research scientist)

This skill does **not** cover tactical AI/ML engineering. For RAG implementation, agent design, prompt engineering, eval infrastructure, model deployment, or cost optimization, see `engineering/rag-architect/`, `engineering/agent-designer/`, `engineering/prompt-governance/`, `engineering/self-eval/`, `engineering/llm-cost-optimizer/`.

## Quick Start

```bash
# Decision A: API vs fine-tune vs build
python scripts/model_buildvsbuy_calculator.py                          # embedded customer-support sample
python scripts/model_buildvsbuy_calculator.py path/to/use_case.json

# Decision B: Risk classification under EU AI Act + US state laws
python scripts/ai_risk_classifier.py                                   # embedded hiring-AI sample
python scripts/ai_risk_classifier.py path/to/use_case.json

# Decision C: API vs self-hosted economics
python scripts/ai_cost_economics.py                                    # embedded 5M tokens/day sample
python scripts/ai_cost_economics.py path/to/workload.json
```

## Key Questions (ask these first)

- **What does this AI need to be good at, and how would you measure it?** (If no eval set, no ship.)
- **What's the SLO on hallucination / error rate?** (Without one, "AI quality" is a vibe.)
- **What happens when the model is wrong?** (Fallback behavior, human-in-the-loop, blast radius.)
- **What's the risk tier under EU AI Act, and is conformity assessment required?** (Determines product launch timeline.)
- **At what monthly token volume does self-hosting beat API?** (Almost never below 100M tokens/month at frontier quality.)
- **Are we hiring an AI engineer or an ML research scientist?** (Different jobs; founders confuse them.)

## Core Responsibilities

### 1. Model Build-vs-Buy

The decision is not "use AI or not" — it's **API vs fine-tune vs in-house** for each use case. Each path has a different TCO curve, latency profile, and capability ceiling.

**Default path: API (frontier model)**
- Use when: well-served by frontier (Claude, GPT, Gemini), QPS < 100, latency budget > 1s, cost < $50K/month
- Why: frontier APIs are 10-100x more capable than what most teams can fine-tune in-house
- Failure mode: API rate limits at scale, vendor lock-in, capability drift between model versions

**Fine-tune a smaller model**
- Use when: domain-specific behavior the API can't be prompted into (medical coding, legal redlining), high volume reducing API cost, latency budget < 500ms, specific style/format consistency required
- Approaches: full fine-tune (rare), LoRA/QLoRA (common), RLHF/DPO (when alignment matters)
- Failure mode: fine-tuned model lags frontier capability within 6-12 months; ongoing retraining cost

**Build from scratch / pre-train**
- Use when: almost never. You're a foundation-model company, OR you have a unique data corpus, $50M+ funding, and 18+ month patience.
- Failure mode: by the time you ship, frontier models have caught up and your sunk cost is unrecoverable

**Run** `model_buildvsbuy_calculator.py` for a use-case-specific recommendation with 3-year TCO. See `references/model_buildvsbuy_strategy.md` for full decision tree.

### 2. AI Risk Classification & Governance

The 2026 question every founder is facing: **does this AI use case trigger high-risk regulatory obligations?**

**EU AI Act (in force 2026) tiers:**

| Tier | Examples | Obligations |
|---|---|---|
| **Prohibited** | Social scoring, real-time biometric surveillance, manipulative AI | Cannot deploy in EU |
| **High-risk** | Employment screening, credit scoring, education access, critical infrastructure, law enforcement, biometric ID | Conformity assessment, registration, post-market monitoring, transparency, human oversight |
| **Limited-risk** | Chatbots, deepfakes, emotion recognition | Transparency: user must know they're interacting with AI |
| **Minimal-risk** | Recommendation systems, spam filters, most B2B SaaS internals | No specific obligations |

**Run** `ai_risk_classifier.py` to classify a use case and get the required-controls list.

**US state patchwork (non-exhaustive):**

- NYC LL 144 — Automated Employment Decision Tools (AEDTs) require annual bias audit + candidate notice
- Colorado AI Act / SB 21-169 — AI in consumer decisions (credit, insurance, employment, housing)
- Illinois HB 53 — AI in interview/hiring
- California SB 1001 — Bot disclosure
- Texas TCPA — Biometric identifier capture
- Federal NIST AI RMF — voluntary; increasingly referenced in contracts

**Industry-specific overlays:**

- Healthcare: FDA AI/ML guidance (2023), MDR (EU) for medical-device AI, 510(k) pathway for AI/ML-enabled medical devices
- Financial: NYDFS Reg 23, FTC Section 5, ECOA for credit decisions
- Insurance: NAIC model bulletin, state insurance commissioner rules

See `references/ai_risk_governance.md` for the full regulatory landscape + governance program checklist.

### 3. AI Cost Economics

**The breakeven question:** at what monthly token volume does self-hosted inference beat API costs?

**Key components:**

- **API cost** — variable, per-token. Frontier models 2026: Claude Sonnet 4.6 ~$3/$15 per M tokens (input/output), GPT-4o ~$2.50/$10, Gemini 2.5 ~$1.25/$5
- **Self-hosted cost** — fixed (GPU commitment) + variable (electricity). H100 spot ~$2-5/hour, A100 spot ~$1-3/hour. Llama 3.1 70B / Qwen 2.5 72B: ~$0.50-2.00 per million output tokens at 70% utilization
- **Hidden costs of self-hosting** — ops on-call, monitoring, model updates, scaling overhead, idle time penalty
- **Hidden costs of API** — rate limits requiring multi-vendor failover, vendor lock-in, capability drift between versions, data residency

**Typical breakeven (frontier-quality):** 100M–500M tokens/month, depending on model size and acceptable quality tradeoff. Below this, API wins. Above this, run the calculator.

**Run** `ai_cost_economics.py` with workload characteristics for a breakeven point + sensitivity to GPU rates and model size.

See `references/ai_cost_economics.md` for the full economics model and operational considerations.

### 4. AI Team Org Evolution

**The wrong question:** "Should we hire an ML engineer or a research scientist?"
**The right question:** "What's the next AI capability we need to ship, and what role unblocks that?"

Stage-to-role map:

| Stage | First AI hire | Then | Then |
|---|---|---|---|
| Pre-PMF | Founder + 1 ML-curious engineer playing with prompts | — | — |
| Series A | **AI engineer** (applied, full-stack; owns prompts/evals/deployment) | Second AI engineer for evals/quality | — |
| Series B | AI/ML platform engineer (inference, evals, observability) | Third AI engineer for production reliability | Data scientist if model is core IP |
| Series C | Manager of AI | ML research scientist (only if model IS the product) | AI safety / red team (if customer-facing AI) |
| Late-stage | Head of AI → CAIO | Multiple research scientists, platform team, safety/red team | Federated AI leads per business unit |

**Critical distinctions:**

- **AI engineer** ≠ **ML engineer** ≠ **research scientist**
  - AI engineer: full-stack + prompts + evals + deployment. Most startups need this, not the others.
  - ML engineer: production deployment, monitoring, retraining infrastructure. Hire after data engineer.
  - Research scientist: model invention, novel architectures. Only at Series C+ if model is core IP.

**Centralize-vs-embed for AI:** AI starts centralized (one team) and stays there longer than data team, because the surface area is smaller. Embed only when AI is being deployed in 4+ product surfaces.

See `references/ai_team_org_evolution.md`.

## Workflows

### Workflow 1: Model Selection Decision (1 hour)
**Goal:** Decide whether a specific use case should use API, fine-tune, or build.

```bash
# 1. Define use_case.json (volume, latency, accuracy, team size, budget)
python scripts/model_buildvsbuy_calculator.py use_case.json
# 2. Review 3-year TCO + breakeven
# 3. Cross-check with cs-cfo-advisor on budget commitment
# 4. Cross-check with cs-cto-advisor on engineering capacity (esp. for fine-tune)
# 5. Log via /cs:decide; consider /cs:freeze 60 on multi-year vendor commitment
```

### Workflow 2: AI Risk Classification (2-4 hours)
**Goal:** Classify a use case under EU AI Act + US state laws, identify required controls.

```bash
# 1. Define use_case.json (decisions affected, users, geography, sector)
python scripts/ai_risk_classifier.py use_case.json
# 2. For HIGH-RISK: budget conformity assessment + registration
# 3. For LIMITED-RISK: implement transparency requirements
# 4. Cross-check with cs-general-counsel-advisor on contractual implications
# 5. Cross-check with cs-ciso-advisor on technical safeguards
# 6. Log via /cs:decide
```

### Workflow 3: API-to-Self-Hosted Breakeven (1 day)
**Goal:** Decide when (and whether) to migrate from API to self-hosted inference.

```bash
# 1. Build workload.json (tokens/day, model size, latency, quality tolerance)
python scripts/ai_cost_economics.py workload.json
# 2. Run sensitivity scenarios (low/mid/high GPU rates)
# 3. Estimate migration cost (engineering time + risk)
# 4. Cross-check with cs-cfo-advisor on capex commitment
# 5. Cross-check with cs-cto-advisor on platform readiness
# 6. Log via /cs:decide; pair with /cs:freeze if signing GPU commitment
```

### Workflow 4: AI Team Roadmap (1 week)
**Goal:** Sequence next 18 months of AI hires aligned to capabilities to ship.

1. List top 5 AI capabilities the product needs in 12 months
2. Map each capability to the role that ships it (see `ai_team_org_evolution.md`)
3. Sequence hires (one role at a time, ramp before next)
4. Cross-check with cs-chro-advisor on comp + leveling
5. Identify the centralize-vs-embed trigger
