AI development services for LLM apps, RAG systems, and workflow automation.
We help companies turn AI into usable product capability: internal assistants, customer-facing copilots, retrieval systems, and automation workflows tied to real business outcomes.
AI development means integrating large language models, retrieval systems, or workflow automation into a real product — not building a model from scratch. Codexa Soft builds LLM-powered features like copilots, RAG search, and automation workflows, typically starting around $5K for a single feature and running to $45K+ for a full multi-feature AI system.
What this service includes
The difference between an AI prototype and an AI product is system design. Our AI development services are built around context, latency, observability, fallbacks, and integration with the rest of your stack.
We start by identifying which workflows actually benefit from AI versus which just sound impressive in a pitch — the difference between a feature that gets used daily and one that gets demoed once and forgotten.
Prompt and workflow design that treats the model as one component in a system, not the whole system — with structured inputs and outputs, retries, and fallback behavior when a response doesn't meet the bar.
Retrieval pipelines that make your own content and data searchable by the model — proper chunking, embedding strategy, and freshness handling so the system answers from your actual data, not stale snapshots or hallucinated specifics.
Guardrails against bad outputs, usage analytics on what people actually ask, and production monitoring so failures get caught by a dashboard, not by a customer complaint.

Our Approach to AI Development
The gap between an AI demo and an AI product is entirely in what happens when the model gets something wrong. A prototype that works on five happy-path examples can fall apart the first time a user asks something unexpected — so we design for the failure case from the start: what the system does when retrieval comes back empty, when the model is uncertain, or when an action shouldn't be taken automatically without a human check.
We rarely build or fine-tune custom models, because for the large majority of commercial use cases it's the wrong lever to pull. Retrieval over your own content, combined with a strong existing model and well-structured prompts, gets better real-world results faster and is easier to maintain than a fine-tuned model that needs retraining every time your product or data changes. We'll say directly if your use case is one of the genuine exceptions.
Latency and cost compound in ways that aren't obvious from a single API call. A workflow that chains multiple model calls, or does retrieval before generation, needs real response-time budgets designed in from the start — otherwise a feature that felt instant in testing becomes noticeably slow once it's doing real work against real data volume.
Every AI feature we ship gets evaluation criteria before it gets a launch date — a defined way to measure whether outputs are actually good, not just plausible-sounding. Without that, teams end up shipping a feature, getting anecdotal complaints months later, and having no systematic way to know if it's actually improved or just changed. Evaluation is what turns 'the AI seems to work' into something you can actually manage.
$5K – $45K+
A single AI feature, like a support copilot or summarization tool, typically starts around $5K. A full RAG system or multi-workflow automation platform usually runs $25K–$45K+, depending on data complexity, integration depth, and evaluation/guardrail requirements.

We prioritize use cases that reduce manual work or create measurable product value.
AI features are designed with guardrails, evaluation, and fallback behavior in mind.
We integrate AI into your existing app and data stack instead of isolating it as a demo feature.

Stronger product differentiation with practical AI features users actually adopt
How we execute this work
We map where AI can realistically remove manual work or improve a decision, then rank candidate use cases by impact versus implementation risk. Most engagements start with the single highest-leverage use case rather than a broad AI roadmap that never ships.
Before committing to a production build, we define what 'good' looks like for the specific use case — accuracy thresholds, acceptable latency, and failure modes that need a fallback — and build a working prototype against those criteria, not just a demo that looks convincing once.
The prototype gets wired into your real application and real data — authentication, existing APIs, and your actual content or database, not a sandboxed dataset. This is usually where the real engineering work is, not the model call itself.
Once live, we track real usage against the evaluation criteria, tune prompts and retrieval based on actual failure cases, and revisit model or provider choice as pricing, capability, or latency tradeoffs shift over time.
Questions clients usually ask
Do you build custom AI models?
In most commercial cases we deliver more value by integrating and orchestrating strong existing models, retrieval systems, and workflow logic around your proprietary data.
Can you add AI into an existing SaaS product?
Yes. Many engagements involve adding search, summarization, support copilots, or automation features into an existing application without rebuilding the whole stack.
How do you handle hallucination risk and output quality?
We reduce risk with retrieval design, prompt structure, guardrails, workflow checks, evaluation criteria, and clear fallback behavior instead of relying on raw model output alone.
Do you work with OpenAI and other model providers?
Yes. We can work with OpenAI and other providers depending on your product needs, cost targets, compliance expectations, and deployment constraints.
How much does AI development cost?
A single AI feature typically starts around $5K. A full RAG system or multi-workflow automation platform usually runs $25K–$45K+. Data complexity and integration depth are the main cost drivers, more than the AI model itself.
Do we need a large dataset to build AI features?
Not always. Many high-value use cases (support copilots, document search, summarization) work well with retrieval over your existing content rather than requiring a large labeled training dataset.
How long does it take to go from prototype to production AI feature?
A working prototype can often be shown in 2-4 weeks. Getting to a production-ready feature with guardrails, monitoring, and evaluation typically adds another 4-8 weeks depending on integration complexity.
