While public benchmarks show general model improvement, they are almost orthogonal to enterprise adoption. Enterprises don't care about general capabilities; they need near-perfect precision on highly specific, internal workflows. This requires extensive fine-tuning and validation, not chasing leaderboard scores.

For specialized, high-stakes tasks like insurance underwriting, enterprises will favor smaller, on-prem models fine-tuned on proprietary data. These models can be faster, more accurate, and more secure than general-purpose frontier models, creating a lasting market for custom AI solutions.

Instead of expensive, static pre-training on proprietary data, enterprises prefer RAG. This approach is cheaper, allows for easy updates as data changes, and benefits from continuous improvements in foundation models, making it a more practical and dynamic solution.

Instead of relying solely on massive, expensive, general-purpose LLMs, the trend is toward creating smaller, focused models trained on specific business data. These "niche" models are more cost-effective to run, less likely to hallucinate, and far more effective at performing specific, defined tasks for the enterprise.

The primary driver for fine-tuning isn't cost but necessity. When applications like real-time voice demand low latency, developers are forced to use smaller models. These models often lack quality for specific tasks, making fine-tuning a necessary step to achieve production-level performance.

The "agentic revolution" will be powered by small, specialized models. Businesses and public sector agencies don't need a cloud-based AI that can do 1,000 tasks; they need an on-premise model fine-tuned for 10-20 specific use cases, driven by cost, privacy, and control requirements.

Basic supervised fine-tuning (SFT) only adjusts a model's style. The real unlock for enterprises is reinforcement fine-tuning (RFT), which leverages proprietary datasets to create state-of-the-art models for specific, high-value tasks, moving beyond mere 'tone improvements.'

For use cases demanding strict fidelity to a complex knowledge domain like Catholic theology, fine-tuning existing models proves inadequate over the long tail of user queries. This necessitates the more expensive path of training a model from scratch.

Despite base models improving, they only achieve ~90% accuracy for specific subjects. Enterprises require the 99% pixel-perfect accuracy that LoRAs provide for brand and character consistency, making it an essential, long-term feature, not a stopgap solution.
