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

# 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 recognitio
