Zero-Shot/ Few-Shot PROMPTING

Zero-shot and few-shot prompting enable LLMs to understand and respond to tasks without prior examples (zero-shot) or with very few examples (few-shot), demonstrating versatile, adaptable learning.

Chain of Thought (COT) PROMPTING

Chain of thought prompting guides LLMs through a step-by-step reasoning process, using intermediate steps to reach a final answer, enhancing problem-solving accuracy and transparency.

Multi-modal (text + image) PROMPTING

Multi-modal COT (Chain of Thought) prompting combines text and images in AI interactions, enhancing understanding and responses by integrating visual cues with descriptive narratives for richer analysis.

Tree-of-Thought (thot) PROMPTING

Tree of Thoughts (ToT) extends chain-of-thought prompting, using a tree structure for systematic problem-solving in language models. It combines thought generation, self-evaluation, and search algorithms for deeper reasoning and exploration in AI decision-making processes.

Self Consistency PROMPTING

Self-consistency in prompt engineering samples diverse reasoning paths to find the most consistent answer, enhancing chain-of-thought performance in tasks involving arithmetic and common-sense reasoning.

General Knowledge PROMPTING

General knowledge prompting guides language models to leverage their broad information base, enabling them to generate responses using wide-ranging, factual content across various subjects and topics.

ReAct PROMPTING

ReAct prompting enables LLMs to generate reasoning traces and take task-specific actions, interfacing with external sources for enhanced, reliable responses and improved performance in language and decision-making tasks.

Directional Stimulus PROMPTING

Directional Stimulus Prompting in language models involves creating targeted prompts or stimuli, often using a tunable policy optimized through Reinforcement Learning. This approach steers the model’s responses towards desired outcomes, enhancing relevance and accuracy in the generated content.

Graph PROMPTING

Graph prompting structures prompts for large language models in a graphical, node-and-edge format. It represents concepts as nodes and their relationships as edges, facilitating more sophisticated, relational reasoning and interconnected output generation, beyond what simple text prompting offers. This method models complex webs of ideas, enhancing the model’s relational processing capabilities.

Change Fatigue vs Automation Fatigue: What Ops Leaders Must Know

In the high-stakes world of finance operations, where regulatory shifts, tech integrations, and market volatility demand constant adaptation, leaders face a dual threat: change fatigue and automation fatigue. Change fatigue arises from relentless organizational transformations, eroding team morale and productivity, while automation fatigue stems from over reliance on AI and automated systems, leading to disengagement and oversight errors.

AI Spend Like a Product: How Finance Teams Take Control

In the rapidly evolving landscape of financial services, AI adoption is accelerating, but so are the associated costs. Finance teams are increasingly treating AI expenditures as they would any core product—scrutinizing, optimizing, and aligning them with business outcomes through FinOps practices.

Model Portability Without the Rewrite Risk

In the multifaceted realm of cross-industry platform operations in 2026, model portability has emerged as a critical imperative, enabling the seamless migration of AI/ML models across diverse clouds, frameworks, or hybrid environments without the burdensome need for extensive code rewrites. This capability is no longer a luxury but a necessity in an era where vendor lock-in, regulatory shifts, and rapid technological evolution can cripple operational agility. At its core, model portability mitigates integration risks—such as compatibility issues, data inconsistencies, or performance degradation—that often plague migrations, ensuring models retain their efficacy and accuracy regardless of the underlying infrastructure. This pillar post delves deeply into sophisticated architectural strategies designed to address these challenges head-on, providing ops teams with the tools to build robust, future-proof systems that prioritize resilience and efficiency.

Token Sprawl → Outcome Metrics: Measuring Decision Throughput

In the rapidly evolving FinOps landscape of the finance sector in 2026, token sprawl represents a insidious challenge: the uncontrolled expansion of large language model (LLM) token usage within AI-powered workflows. This phenomenon silently erodes operational budgets, frequently driving up costs by 40-60% through inefficient token consumption that fails to deliver proportional business value. Often stemming from over-reliance on verbose prompts, redundant queries, and unoptimized model chaining, token sprawl can transform promising AI initiatives into financial liabilities, particularly in high-stakes areas like credit underwriting, treasury management, and claims adjudication.

How Boards Should Think About AI Risk (2026 update: regs & economics)
