SaaSpark The frontier-model landscape moves fast. **Anthropic's Claude** is the most-adopted alternative for code-heavy and long-context workloads, plus its native Model Context Protocol support is a real differentiator. **Google Gemini** is the multimodal-first option with the most generous free tier. The third option, **Vercel AI SDK**, isn't a model — it's the abstraction layer that lets you swap between providers without rewriting your app code.
