# Pioneer

> Pioneer is an agentic fine-tuning platform that automatically trains, evaluates, and deploys optimized open-source language models using live inference data.

Pioneer is an AI platform by Fastino that enables developers to fine-tune and deploy open-source language models in minutes using a single prompt. The platform features Adaptive Inference, which continuously monitors live traffic, generates training data, and promotes improved model checkpoints automatically — no manual retraining required. Pioneer supports leading OSS models including Llama 3, Qwen, DeepSeek, and GLiNER, and claims 2x price efficiency versus GPT-4o with 99.99% API uptime.

- **Adaptive Inference** — *Select a baseline OSS model and Pioneer automatically retrains it on live inference data, improving accuracy over time without manual intervention.*
- **One-Shot Fine-Tuning** — *Update models with a single prompt through Pioneer's agentic fine-tuning pipeline, dramatically reducing the complexity of model customization.*
- **Continuous Evaluation & Training** — *Pioneer automatically evaluates model behavior, generates synthetic training data, and promotes improved checkpoints to production.*
- **High-Performance Inference API** — *Deploy models via a production-grade API with 99.99% uptime and high-throughput serving for real-world workloads.*
- **Downloadable Model Weights** — *Pro and Research plan users can download fine-tuned model weights for local or custom deployment.*
- **Multi-Model Support** — *Choose from Llama 3, Qwen, DeepSeek, GLiNER, and other state-of-the-art open-source models, with Day 0 support for the latest releases.*
- **Deep Research Agent Mode** — *Available on the Research plan, enabling multi-hour experiment tracking and advanced Adaptive Inference workflows.*
- **Team Collaboration** — *Invite team members to share inference and fine-tuning resources under a single account on Pro and above.*
- **Usage-Based Model Pricing** — *Pay per million tokens for base model inference, with transparent per-model pricing listed on the pricing page.*
