Frequently Asked Questions
Xsai vs Temporal AI: which should you choose?
If you need a featherweight AI SDK for browser/edge apps that talks to OpenAI-compatible APIs, Xsai is the clear winner. But if you're building reliable, crash-proof AI agents or multi-step workflows that require retries, Saga patterns, and human-in-the-loop, Temporal is the battle-tested choice, despite its heavier footprint.
Can Xsai be used for AI agent orchestration like Temporal?
No, Xsai is focused on making individual AI API calls lightweight; it has no workflow engine, retry logic, or state persistence.
Does Temporal support browser runtime?
Temporal's SDKs are designed for server-side runtimes (Node.js, Python, Go, etc.) and do not run in the browser.
Is Xsai compatible with non-OpenAI providers?
It only supports OpenAI-compatible APIs; providers like Anthropic or Google work only via their OpenAI-compatible endpoints.
What does 'usage-based billing' mean for Temporal Cloud?
You pay per billable action (e.g., workflow start, activity, timer). The June 2026 update improved cost transparency with a Billable Action Count metric.
Can I self-host Temporal for free?
Yes, Temporal Server is open-source and free to self-host, but you miss out on Cloud features like automatic scaling and SLA.
Does Xsai have any official support or enterprise plans?
No, Xsai is community-maintained open-source; no enterprise support or SLAs.
Which tool has better integration with the OpenAI Agents SDK?
Temporal has a direct integration with the OpenAI Agents SDK announced at Replay 2026.
Is Temporal overkill for simple text generation?
Yes, if you just need to call an LLM once, Temporal adds unnecessary complexity; Xsai is a simpler choice.
