# Overview

> Train models using reinforcement learning in minutes

Fireworks RFT helps you train frontier models like DeepSeek V3 and Kimi K2 to **outperform closed models for your product use case, using reinforcement learning.** Fireworks RFT is powerful and easy to use for developers and enterprises:

* **No infrastructure:** Train frontier models without managing GPUs or RL infra
* **Production-ready:** Built-in tracing, monitoring, security & one-click deploy
* **Fast iteration:** From evaluator setup to deployed model in hours, not weeks

<Tip>
  See how [Genspark](https://fireworks.ai/blog/genspark) and [Vercel](https://fireworks.ai/blog/vercel) used Fireworks RFT to train open models for agentic use cases, outperforming leading closed models.

## Quickstart: Pick Your Training Approach

<CardGroup cols={3}>
  <Card title="Single-Turn Training" icon="laptop-code" href="/fine-tuning/quickstart-math">
    **⏱️ 15 minutes**

    **Best for:** Testing locally, simple task training

    **How it works:** Iterate on your evaluator and use it to train a small model on Fireworks.
  </Card>

  <Card title="Remote Agents" icon="server" href="/fine-tuning/quickstart-svg-agent">
    **⏱️ 1-2 hours**

    **Best for:** Agents, multi-turn workflows, existing services

    **How it works:** Rollouts happen in your environment. Connect via HTTP with tracing.
  </Card>

  <Card title="Secure Training (BYOB)" icon="shield-check" href="/fine-tuning/secure-fine-tuning">
    **⏱️ 2-4 hours**

    **Best for:** Sensitive data, compliance, enterprise

    **How it works:** Training data never leaves your GCS/S3 bucket. Full data isolation.
