Switch in one line

Both models live behind Railwail's OpenAI-compatible endpoint. Replace the model string and you are done.

JavaScript / TypeScript
import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.RAILWAIL_API_KEY,
  baseURL: "https://railwail.com/v1",
});

// Before β€” using AuraFlow v0.3
let r = await client.chat.completions.create({
  model: "fofr/aura-flow",
  messages: [{ role: "user", content: "Hello" }],
});

// After β€” switched to InstantID
r = await client.chat.completions.create({
  model: "zsxkib/instant-id",
  messages: [{ role: "user", content: "Hello" }],
});

Frequently asked questions

Which is cheaper, AuraFlow v0.3 or InstantID?
AuraFlow v0.3 and InstantID cannot be compared on per-token price: at least one of them has no per-token price listed (it is priced per run or not yet priced). See each model page for its current price.
Which has more context, AuraFlow v0.3 or InstantID?
AuraFlow v0.3 and InstantID have similar context windows (β€” vs β€”).
Is AuraFlow v0.3 better than InstantID for coding?
For coding-heavy workloads we lean toward AuraFlow v0.3 on this comparison β€” it scores higher on the relevant heuristics (category, tags, or context window). Both models are usable for code via Railwail's OpenAI-compatible endpoint, so the safest path is to A/B test on your own prompts.
Can I use both AuraFlow v0.3 and InstantID via Railwail?
Yes. Both AuraFlow v0.3 and InstantID are accessible through a single Railwail API key and the OpenAI-compatible /v1/chat/completions endpoint. You only change the "model" parameter to switch between them β€” no SDK swap, no separate billing.
How do I switch from AuraFlow v0.3 to InstantID?
Replace the model identifier "fofr/aura-flow" with "zsxkib/instant-id" in your request payload. Everything else β€” API key, base URL, request shape β€” stays the same. See the code example on this page for the exact one-line change.
