# Local AI Hardware — DGX Spark
> Fonte: `1p0HXLv_5wM` (DGX Spark $3k), transcript `1p0HXLv_5wM.pt.dedup.txt:130-180`
Transição cloud → edge: DGX Spark na mesa, 100% grátis/offline, hoje nicho (heavy users), tendência baratear para notebooks.
## Quando usar
- Heavy user/empresa, custo cloud > $500/mês
- Precisa offline, privacidade, latência zero
- Comparar DGX Spark vs `ito-compute` (aluguel) vs Apple Silicon
## Decisão Buy vs Rent
| Critério | Comprar (DGX Spark) | Alugar (ito-compute) |
|---|---|---|
| Custo inicial | $3k | $0 |
| Custo/mês | $0 (energia) | $50-300 |
| Offline | Sim | Não |
| Upgrade | Manual | Instant |
TCO = `hardware + energia*meses` vs `tokens/mês * $/token` (`cost-aware-llm-pipeline`).
## Workflow
1. Estime tokens/mês + custo cloud (`roteamento-modelos-baratos`)
2. Calcule TCO 12 meses
3. Se buy: `DGX Spark` → `vLLM` local → benchmark `local-llm-efficiency`
4. Se rent: use `ito-compute`
## Referências
## Exemplo
```text
Cloud $600/mês em tokens → TCO 12m: $7,2k cloud vs $3k DGX + energia
Buy: DGX Spark → vLLM local → benchmark (tokens/s, qualidade vs cloud)
Rent: segue no ito-compute (upgrade instant, zero capex)
Decide pelo número, não pelo hype do "100% offline"
```
