Pioneer is designed to make fine-tuning small language models (SLMs) as simple as possible. The entire process takes four steps:
  1. Create a dataset — Upload your own data or generate synthetic examples with Felix, Pioneer’s built-in synthetic data tool. See Datasets.
  2. Start a training job — Pick a base model, point it at your dataset, and submit. All hyperparameters have sensible defaults so you don’t need to tune anything to get started. See Training.
  3. Wait for completion — Your job moves through pending → running → complete. Small datasets typically finish in a few minutes.
  4. Run inference — Use your job ID as the model identifier. Encoder models accept a text and schema; decoder models are OpenAI-compatible. See Inference.
For a full walkthrough, check out the NER fine-tuning guide or the LLM fine-tuning guide.
No. Storage is free for all datasets on every plan. You won’t be charged for the datasets you create or upload to Pioneer.
Describe your domain and the labels you want to train for, and Pioneer’s Felix pipeline generates realistic labeled examples at scale. This lets you bootstrap a training dataset without any manual annotation — useful when you’re starting from scratch or need to expand coverage for edge cases.  
Pioneer gives you access to a broad catalog of decoder models, including Kimi-K2, Qwen3, DeepSeek-V3, Llama, Gemma, and more, all callable through a single unified API.
Swap the model name for any supported decoder,deepseek-ai/DeepSeek-V3.1, Qwen/Qwen3-32B,meta-llama/Llama-3.3-70B-Instruct, and others. OpenAI-compatible and Anthropic-compatible formats are also supported. To see the full live catalog, call GET /base-models. See Inference for full details.
Yes, by default Pioneer may use your data to improve models. However, you can opt out on the Pro and Custom plans. Custom plans also let you run fine-tuning privately inside your own VPC so your data never leaves your infrastructure.Contact the team to learn more about Custom plan options.
Teams in Pioneer are used for shared billing — each member still has their own private workspace. Model sharing between teammates is not built into Teams directly.If you need to share models with your team, get in touch and the team can walk you through the best approach for your use case.
Encoder models (like GLiNER) are trained to understand and extract structured information from text, they’re ideal for NER, classification, and JSON extraction tasks. They’re fast, efficient, and run on CPU, making them cheap to serve at scale. Decoder models (like Llama or Qwen) are generative, they produce text, making them suited for summarization, Q&A, chat, and instruction-following tasks.Pioneer supports both. If your task has a defined output structure (extract these entity types, classify into these categories), use an encoder. If your task requires generating free-form text, use a decoder. When in doubt, start with an encoder, they train faster, cost less, and are easier to evaluate.
Pioneer runs evaluations automatically after training and reports F1, precision, and recall on your held-out validation set.If your score is lower than expected, run a manual evaluation against a separate dataset for a cleaner signal. You can also inspect per-example predictions to identify where the model is failing, then use those gaps to generate targeted synthetic data. See Evaluations and Synthetic Data.
GLiNER is an open-source encoder model architecture designed specifically for named entity recognition and structured extraction. Unlike decoder models that generate text token by token, GLiNER classifies spans of text directly, making it significantly faster and more accurate for extraction tasks.Use GLiNER when you need to extract specific entity types (people, organizations, products, dates), classify text into predefined categories, or run high-volume inference where latency and cost matter. Pioneer’s fine-tuning pipeline is built around GLiNER. You can go from a domain description to a production-ready extraction model in minutes, with no GPU required on your end.
As part of ongoing US export control policy on AI, including directives issued in June 2026, each model provider has updated their availability policies to comply.
Users located in countries subject to US sanctions and export restrictions (including China, Russia, Iran, North Korea, Cuba, Syria, and Belarus) are not able to access models on Pioneer.
For the full and current list of supported countries, refer directly to each provider: OpenAI, Anthropic, Google Gemini, and Meta Llama 4.
These policies are actively evolving. If you believe your access has been incorrectly restricted, please contact our Support team.
