Model-agnostic architecture separates your application logic from any specific LLM provider through abstraction layers, standardized interfaces, and evaluation-driven model selection. This means you can upgrade, swap, or route between providers based on cost, quality, and latency without touching business logic or user-facing code.

You are building AI features and want to avoid deep coupling to a single provider's API, pricing, or availability guarantees.
A structured delivery path—not vague promises.
Map provider-specific calls, data formats, and SDK dependencies.
Unified interface for completion, embedding, and tool-call operations.
Provider-specific adapters behind the shared interface.
Automated quality and cost comparison across providers per use case.
Balanced guidance—not one-size-fits-all answers.
Some advanced features (vision, audio, fine-tuning APIs) may require provider-specific code paths—isolate them.
Abstraction layers cost development time now but prevent costly migrations later.
Primary capability pages for this topic.
Add production-ready AI capabilities to an existing mobile app, web platform, SaaS product, or internal system without rebuilding the entire product. We integrate intelligent search, assistants, automation, recommendations, document intelligence, and AI agents with your current architecture, data, APIs, authentication, and workflows.
Choose the right AI approach for production—direct API calls, retrieval (RAG), or fine-tuning—based on data, cost, and maintenance.
SDKs help but are one piece. True agnosticism also requires evaluation, prompt management, fallback logic, and observability independent of any SDK.
For production systems expected to run long-term, yes. For throwaway prototypes, it adds unnecessary complexity.
Initial setup takes effort; afterward it speeds up provider experiments and migrations.
Isolate them in adapter extensions so core logic stays portable.
Yes—as part of AI integration or architecture review engagements.
