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 WizardCoder 33B
let r = await client.chat.completions.create({
  model: "lucataco/wizardcoder-33b-v1.1-gguf",
  messages: [{ role: "user", content: "Hello" }],
});

// After — switched to Code Llama 13B Instruct
r = await client.chat.completions.create({
  model: "meta/codellama-13b-instruct",
  messages: [{ role: "user", content: "Hello" }],
});

Frequently asked questions

Which is cheaper, WizardCoder 33B or Code Llama 13B Instruct?
WizardCoder 33B and Code Llama 13B Instruct 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, WizardCoder 33B or Code Llama 13B Instruct?
WizardCoder 33B and Code Llama 13B Instruct have similar context windows (16K tokens vs 16K tokens).
Is WizardCoder 33B better than Code Llama 13B Instruct for coding?
For coding-heavy workloads we lean toward WizardCoder 33B 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 WizardCoder 33B and Code Llama 13B Instruct via Railwail?
Yes. Both WizardCoder 33B and Code Llama 13B Instruct 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 WizardCoder 33B to Code Llama 13B Instruct?
Replace the model identifier "lucataco/wizardcoder-33b-v1.1-gguf" with "meta/codellama-13b-instruct" 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.
