Want to add AI to your product without the hype? StackSolution integrates LLMs (OpenAI and Anthropic Claude) into real software — assistants and chatbots your users trust, RAG search over your own docs and data, and workflow automation that clears the busywork. We keep the team small and senior, so one engineer owns the build from prompt design to production. Everything ships with evals and guardrails so answers stay grounded, plus latency and cost controls so the bill and the response times both stay sane.
In 2026, a basic chatbot or single AI feature typically runs $5,000–$15,000, a RAG assistant over your own docs $15,000–$40,000, and multi-step agents or automation $40,000+. Ongoing API usage is usually $100–$2,000/month depending on traffic and model. We quote fixed-scope, and design for caching and cheaper models where they fit, so the running cost stays predictable.
A focused chatbot or single LLM feature usually ships in 2–4 weeks; a RAG assistant grounded in your documents in 4–8 weeks; a multi-tool agent workflow in 8–12 weeks. We deliver in weekly milestones with a working demo, so you can test answer quality on your real data early instead of waiting for a final handover.
RAG (retrieval-augmented generation) feeds the model your own docs at query time, so answers cite current, private data without retraining — it's cheaper, faster to update, and far less prone to hallucination than fine-tuning for most use cases. In 2026 we reach for RAG first, and only fine-tune when you need a fixed tone or format at high volume. We build the embeddings, vector store, and retrieval end to end.
We ground responses in your data with RAG, add guardrails and input/output validation, and defend against prompt injection. Before launch we build an eval set — typically 50–200 graded test cases — so every prompt change is measured, not guessed. Agents get tool restrictions, retries, and human-in-the-loop checkpoints on risky actions, so the system fails safe rather than confidently wrong.
Both are excellent in 2026 — Claude tends to shine on long documents, careful reasoning, and safety-sensitive work, while OpenAI has a broad tooling and ecosystem. We build on both and pick per use case, and we structure the code behind a model-agnostic layer so you can switch or route between them as prices and capabilities shift, with no lock-in.
Send us the rough idea, even if it's messy. We'll come back with how we'd build it and roughly how long it'd take, usually within a day.
