What sets them apart

Starting from an open-weight base model, community and independent teams fine-tune specialized variants for narrower tasks — legal drafting, roleplay, coding in a specific language — often outperforming the general base model on that narrow task.

How they're built

Fine-tuning adjusts a pretrained model's weights slightly using a smaller, task-specific dataset, which is far cheaper than training a model from scratch.

Where they fit

Best when a narrow, well-defined task needs to run cheaply and quickly, and a general-purpose frontier model would be overkill for that specific job.

Choosing the right model for your agent? Model selection and integration is part of every build we do — let's talk through your use case.
