Fine-tuned models deliver better results for specialized work - they're faster, cheaper, and easier to train than general-purpose AI. On MLStack, engineers can share these fine-tuned models, so you can find one for your use case and get started in minutes instead of weeks.
Lightweight fine-tuned models for specialized tasks
Skill modules that plug into a compatible LLM, adding specialized capabilities without retraining the entire model.
1000× smaller than full models (10-100MB), train in minutes or hours instead of days, and can be instantly swapped for different abilities.
Domain writing styles, technical docs, customer support, data extraction, and task-specific instruction following.

Define structured JSON outputs for LLMs
JSON Schema definitions that force LLMs to return data in the format you specify. No more unpredictable outputs.
Eliminate unreliable output formats and parsing errors. Get validated, type-safe data every single time.
Document extraction (invoices, resumes), API responses, database records, and multi-step AI workflows.
Specialized models powering agents that connect to your external services and APIs
Build agents that can use tools and execute multi-step workflows. Perfect for customer support, data analysis, and automation.
Connect your agents to external APIs - from CRMs and payment processors to databases and custom endpoints. Give your LLMs real-world superpowers.
