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 Codestral
let r = await client.chat.completions.create({
  model: "codestral-latest",
  messages: [{ role: "user", content: "Hello" }],
});

// After — switched to Code Llama 34B Instruct
r = await client.chat.completions.create({
  model: "meta/codellama-34b-instruct",
  messages: [{ role: "user", content: "Hello" }],

Frequently asked questions

Which is cheaper, Codestral or Code Llama 34B Instruct?
Codestral and Code Llama 34B 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, Codestral or Code Llama 34B Instruct?
Codestral has the larger context window at 256K tokens, compared to 16K tokens for Code Llama 34B Instruct.
Is Codestral better than Code Llama 34B Instruct for coding?
For coding-heavy workloads we lean toward Codestral 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 Codestral and Code Llama 34B Instruct via Railwail?
Yes. Both Codestral and Code Llama 34B 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 Codestral to Code Llama 34B Instruct?
Replace the model identifier "codestral-latest" with "meta/codellama-34b-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.
