---# 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/`.

- **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
- 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.
- **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 |
- 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)
- [ai_team_org_evolution.md](references/ai_team_org_evolution.md) — Stage-to-role map + role definitions (AI engineer ≠ ML engineer ≠ scientist) + anti-patterns

**Version:** 1.0.0
**Status:** Production Ready
**Disclaimer:** AI regulation is evolving rapidly. This skill surfaces decisions and tradeoffs as of 2026 but cannot replace qualified AI counsel for binding compliance decisions, especially under EU AI Act conformity assessments.
