Quick answer
How do you add ChatGPT or another LLM to an existing product?
You call the model from your own server through its API, send it the right context and instructions, validate its output, and show the result inside your app with authentication, rate limits, caching and monitoring around it. Limbani Softwares integrates LLMs into existing web apps, SaaS platforms and CRMs, compares models on your data and keeps costs predictable.
RAG vs fine-tuning vs prompt engineering: when to use each
Start with prompt engineering, add retrieval when answers must come from your own documents, and fine-tune only for a narrow, repetitive task where style or format matters more than fresh knowledge.
| Prompt engineering | RAG (retrieval) | Fine-tuning | |
|---|---|---|---|
| Adds your knowledge | Only what fits in the prompt | Yes, from documents at query time | Partly; bakes patterns in, not facts |
| Keeps answers current | Manual updates | Yes, update the documents | No, retrain needed |
| Citations | No | Yes | No |
| Data needed | Examples in the prompt | Your documents | Hundreds to thousands of labelled examples |
| Cost to set up | Lowest | From $1000, priced on scope | Higher; training and evaluation |
| Best for | Fixed tasks, quick wins | Assistants over your content | Consistent style, narrow formats |
Engagement models and pricing for LLM development
Every project starts from $1000 and is priced on scope after a discovery call. Pick the model that matches how well the scope is known.
| Model | Best for | How it is priced | Typical timeline |
|---|---|---|---|
| Fixed scope | Small, well-defined work such as a proof of concept, an MVP slice or a redesign | A fixed price for a written scope, from $1000, priced on scope | 2 to 12 weeks per phase |
| Time and materials | Products whose requirements change as you learn from users | Monthly, for the hours actually worked, with a budget cap you set | Ongoing in two-week sprints |
| Dedicated team | A long roadmap that needs steady capacity next to your own team | A fixed monthly rate per person; scale up or down with notice | 3 months and longer |
Most clients start with a fixed-scope discovery or first release, then move to time and materials or a dedicated team.

Yes. We integrate OpenAI's models and other large language models into existing web apps, SaaS products, mobile apps and internal tools through secure server-side APIs, so features like summaries, drafting, smart search or chat work inside the product your users already know.
It depends on quality needs, latency, cost, data residency and context length. We usually prototype the same feature with two or three models, measure accuracy, speed and cost on your real data, then recommend one with a fallback model for resilience.
We choose the smallest model that meets the quality bar, cache repeated requests, trim prompts and context, batch background work, set per-user limits and monitor token spend per feature so costs stay predictable as usage grows.
It can be. We call models from your server, never expose keys in the browser, remove or mask sensitive data where possible, use provider settings that exclude your data from training, and add protections against prompt injection.
An LLM development company builds features and products on large language models: assistants that answer from your data, drafting and summarisation inside your app, document extraction, and agents that complete tasks. Limbani Softwares handles model selection, retrieval, prompts and tools, evaluation, security and the product engineering around the model.
When prompts or documents contain data that cannot leave your environment, when regulations require data residency, or when usage is high enough that a self-hosted open-source model costs less than API calls. We deploy open-source models in your cloud or use enterprise API tiers with training disabled, and we tell you which is cheaper for your volume.
Use retrieval-augmented generation when the model needs to answer from your documents and the content changes; it is cheaper to update and keeps citations. Fine-tune when you need a consistent style or format on a narrow, repetitive task. Many products use RAG first and fine-tune later, if at all.
