Recognizing there is no single "best" LLM, AlphaSense built a system to test and deploy various models for different tasks. This allows them to optimize for performance and even stylistic preferences, using different models for their buy-side finance clients versus their corporate users.

Rather than relying on a single LLM, LexisNexis employs a "planning agent" that decomposes a complex legal query into sub-tasks. It then assigns each task (e.g., deep research, document drafting) to the specific LLM best suited for it, demonstrating a sophisticated, model-agnostic approach for enterprise AI.

The model uses a Mixture-of-Experts (MoE) architecture with over 200 billion parameters, but only activates a "sparse" 10 billion for any given task. This design provides the knowledge base of a massive model while keeping inference speed and cost comparable to much smaller models.

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.

Performance on knowledge-intensive benchmarks correlates strongly with an MoE model's total parameter count, not its active parameter count. With leading models like Kimi K2 reportedly using only ~3% active parameters, this suggests there is significant room to increase sparsity and efficiency without degrading factual recall.

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.

Enterprises will shift from relying on a single large language model to using orchestration platforms. These platforms will allow them to 'hot swap' various models—including smaller, specialized ones—for different tasks within a single system, optimizing for performance, cost, and use case without being locked into one provider.

Autoencoding models (e.g., BERT) are "readers" that fill in blanks, while autoregressive models (e.g., GPT) are "writers." For non-generative tasks like classification, a tiny autoencoding model can match the performance of a massive autoregressive one, offering huge efficiency gains.

Artificial Analysis found its knowledge-based "Amnesian's" accuracy benchmark tracks closely with an LLM's total parameter count. By plotting open-weight models on this curve, they can reasonably estimate the size of closed models, suggesting leading frontier models are in the 5-10 trillion parameter range.
