## Where each ships

### ChatGPT-only stacks (1)

- [Indie SaaS](https://aistack.sh/stack/indie-saas) — Claude is the pair, Figma is the design surface, Vercel is the deploy target. End-to-end indie SaaS from idea to billing in a weekend.

### Mistral-only stacks (2)

- [Multilingual content factory](https://aistack.sh/stack/multilingual-content) — Most teams writing multilingual content default to one frontier LLM and accept slightly off-tone output in non-English languages. The cost: native readers spot it. The fix: route by language. Qwen handles Chinese / Japanese / Korean with depth no Western model matches; Mistral covers the European languages with EU-native nuance; Claude handles the English source.
- [Open-weight LLM stack](https://aistack.sh/stack/open-weight-llm) — Closed-weight APIs are the right default for most teams. They're not the right default for a regulated industry, a privacy-led product, or anyone whose customers ask 'where does this data go'. Llama and Mistral are open-weight families that ship near-frontier quality with the receipts. Use Claude on a small eval set to confirm the open-weight model holds up on YOUR task.
