Model Training

General AI

Model training is the process of shaping AI behavior through structured data and controlled optimization. While prompt engineering adjusts surface behavior, true fine-tuning alters internal understanding.

Modern techniques like LoRA (Low-Rank Adaptation) allow efficient training by modifying small matrices instead of entire networks, making adaptation faster and cheaper.

Theta Tech applies these techniques with surgical precision. From dataset curation to parameter tuning, we craft models that align with your objectives: LLMs, computer vision systems, or time-series predictors alike.

Understanding the Concept

When a model fails to behave as expected, most teams adjust prompts.

Sometimes, that isn’t enough. Without targeted fine-tuning, systems remain generic and misaligned.

Theta Tech ensures your models think in your language, not someone else’s.

Why This Matters

Refining Intelligence Through Data and Design

When a model fails to behave as expected, most teams adjust prompts.

Sometimes, that isn’t enough. Without targeted fine-tuning, systems remain generic and misaligned.

Theta Tech ensures your models think in your language, not someone else’s.
