Why context is critical for building effective agents

As we build the next generation of AI development platforms, we observe a pattern across countless customer implementations: the single greatest determinant of AI system effectiveness isn't model selection or parameter count—it's context.

In this post, we share what we've learned about why context matters and how it transforms AI agent capabilities from merely functional to truly exceptional.

What is context in AI?

Context represents the collective information that enables an AI agent to understand and respond appropriately to a specific situation. It's the difference between an AI that responds with generic knowledge (generic data in, generic experience out) and one that provides personalized, relevant insights tailored to the specific experience.

To date, many teams assume that context is the language model’s responsibility — leading to a common pattern of simply sending queries to a model and expecting it to somehow “know” what is relevant or not. There might be an inclusion of a few recent conversation turns but this pattern fails to curate the info the model actually needs to perform effectively.

The most successful AI implementations flip this paradigm — it is the app’s responsibility for strategically managing and providing appropriate context to the model. Rather than treating the model as a magical black box that should somehow understand what matters, apps should take ownership to strategically collect, curate, and provide precisely the context needed for each specific interaction.

When building effective agents, context falls into three critical buckets:

1. Conversational memory: The history of past interactions with users, including previous questions, responses, clarifications, and established user preferences. This creates continuity across interactions and prevents users from having to repeat themselves.
2. Organizational knowledge: Your company's proprietary information, including documents, knowledge bases, policies, product details, and institutional wisdom. This grounds the AI in your specific domain expertise rather than relying on generic model knowledge.
3. Real-time information: Dynamic data from your systems, APIs, databases, and external sources that provide up-to-the-minute information relevant to the current task or question.

Each of these context types requires different retrieval methods, update frequencies, and integration approaches — which is precisely why context management and orchestration is critical. A one-size-fits-all approach to context fails to capture the richness and specificity needed for agents, agentic flows, and AI-powered services.

Why semantic search alone is not enough

Many organizations have invested heavily in semantic search technologies, believing this approach would solve their context challenges. While semantic search represents an important advancement over keyword-based methods, it falls short of comprehensive context management for several critical reasons:

Limited understanding of relationships: Semantic search can identify conceptually similar content but struggles to understand complex relationships between entities, processes, and concepts that are critical for genuine comprehension.

Absence of reasoning capabilities: Finding relevant information is only the first step. True context management enables systems to reason about the implications of that information, apply it to specific scenarios, and generate novel insights—capabilities that go beyond what search alone can provide.

Lack of persistence and learning: Search systems treat each query as an isolated event, lacking the capacity to build cumulative understanding across interactions or refine their internal models based on outcomes and feedback.

Static rather than dynamic: Most semantic search implementations access static snapshots of information rather than continuously updating based on the evolving state of the business, conversations, and real-time data.

Missed opportunities for synthesis: Powerful AI applications often require synthesizing information across multiple documents, knowledge bases, and data sources—something that traditional search paradigms aren't designed to support.

Poor handling of ambiguity: Without broader contextual awareness, semantic search frequently misinterprets ambiguous queries or fails to recognize when clarification is needed.

True context transcends search to create a living, evolving knowledge system that adapts to user needs, learns from interactions, and continuously improves its capabilities.

Why context changes everything

When implemented correctly, robust context delivers transformative benefits that fundamentally change what's possible with AI systems:

Enhanced accuracy and relevance: AI agents with rich context deliver more precise, personalized responses. We've seen accuracy improvements when proper contextual systems are implemented. These aren't marginal gains—they're the difference between systems that customers leave in POCs and ones they push into production. For example, a customer support AI with access to a user's complete purchase history and previous support interactions can immediately understand complex issues without forcing users to repeat information.

Deeper reasoning capabilities: With proper context, AI systems can move beyond pattern matching to genuine reasoning. They can connect disparate pieces of information, identify underlying principles, and generate novel insights by traversing relationships within your contextual data. This enables the transition from simple Q&A systems to genuine thought partners for your teams.

Adaptive learning and improvement: Context-aware systems can systematically capture feedback, understand where gaps exist, and continuously improve their performance. Each interaction becomes an opportunity to refine the context model rather than treating every query as an isolated event.

Enhanced security and compliance: Robust context management allows for fine-grained control over what information is available to AI systems in different scenarios, enabling organizations to implement proper governance, maintain audit trails, and ensure compliance with regulatory requirements.

Future-proof architecture: As models evolve, a context-centric approach means you can swap underlying models without rebuilding your entire system. Your organization's valuable context becomes a durable asset independent of which AI provider or model you choose to leverage.

Why a data-first strategy is essential

Organizations today face a critical choice: continue treating AI as a series of isolated point solutions or implement a cohesive strategy that places data and context at the center of their AI initiatives. A data-first approach provides the foundation that enables sustainable AI adoption across the enterprise.

This approach recognizes that your organization's unique data assets—from customer interactions to operational knowledge—represent your true competitive advantage in AI implementation. While foundation models may become commoditized, your proprietary data is irreplaceable. A unified platform that prioritizes intelligent context management, seamless data integration, and flexible model orchestration allows teams to build on this advantage incrementally, measuring results and scaling successful approaches without constant reinvention.

By investing in a context-centric architecture, teams create an environment where each AI implementation strengthens and enriches the contextual foundations without overwhelming models with irrelevant information. Its a virtuous cycle of improvement for teams now and over time.

The path forward

Success in implementing transformative AI is recognizing context as a strategic advantage. The model landscape will continue to evolve rapidly, but your proprietary context—your data, your knowledge, your customer insights—represents your true competitive moat.

Context isn't just another component of AI system design—it's the foundation upon which all truly effective AI agents must be built.
