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 — using Consistent Character
let r = await client.chat.completions.create({
  model: "fofr/consistent-character",
  messages: [{ role: "user", content: "Hello" }],

Frequently asked questions

Which is cheaper, Consistent Character or FLUX 1.1 Pro?
Consistent Character and FLUX 1.1 Pro 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, Consistent Character or FLUX 1.1 Pro?
Consistent Character and FLUX 1.1 Pro have similar context windows (— vs —).
Is Consistent Character better than FLUX 1.1 Pro for coding?
For coding-heavy workloads we lean toward Consistent Character on this comparison — 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 Consistent Character and FLUX 1.1 Pro via Railwail?
Yes. Both Consistent Character and FLUX 1.1 Pro 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 — no SDK swap, no separate billing.
How do I switch from Consistent Character to FLUX 1.1 Pro?
Replace the model identifier "fofr/consistent-character" with "black-forest-labs/flux-1.1-pro" in your request payload. Everything else — API key, base URL, request shape — stays the same. See the code example on this page for the exact one-line change.
