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 BLIP
let r = await client.chat.completions.create({
  model: "salesforce/blip",
  messages: [{ role: "user", content: "Hello" }],
});

// After — switched to Depth Anything v2
r = await client.chat.completions.create({
  model: "chenxwh/depth-anything-v2",
  messages: [{ role: "user", content: "Hello" }],
});
Python
from openai import OpenAI

client = OpenAI(
