What We Do ?

What Our Generative AI Development Services Include

We turn foundation models into products that work with your data, your systems, and your users. Every build covers the full path: use case, data, model choice, integration, evaluation, and deployment.

Custom LLM Development

Fine-tune open-weight or hosted models on your domain data when prompting and retrieval are not enough for the accuracy or format you need.

Knowledge Assistants with RAG

Assistants that answer from your documents, policies, and databases through retrieval-augmented generation, with sources shown for each answer.

Multimodal Applications

Products that work across text, images, voice, and documents, such as document analysis or image generation features inside your app.

AI Agents and Copilots

Assistants inside your product or tools that take actions, not just answer questions. See our AI agent development services.

Content and Document Tools

Drafting, summarization, and extraction tools that follow your brand and review rules, with a human approval step where needed.

Enterprise Chatbots

Secure chat interfaces connected to your company’s data and knowledge base, for employees or customers. See AI chatbot development.

Data Privacy and Governance

Access controls on what the model can retrieve, data anonymization where needed, and private deployment options that keep data inside your environment.

Deployment and LLMOps

Hosting, monitoring, evaluation, and model updates, so your generative AI product keeps working after launch.

Innovation Stack

Our Generative AI Development Capabilities

Beyond calling a model API, we build the engineering around it: data pipelines, retrieval, evaluation, and deployment.

Custom LLM Training and Fine-Tuning

Adapt models to your domain data and output formats when off-the-shelf models fall short. Not sure which approach fits? Read RAG vs fine-tuning.

Prompt Engineering and Optimization

Design prompts, templates, and guardrails that make model behavior more consistent and testable.

RAG Systems

Combine generative models with search across your documents and data for answers grounded in sources.

Multimodal Input and Output

Systems that understand and generate text, images, audio, and documents.

Conversational AI and Chat Interfaces

Chatbots, assistants, and AI copilots with memory and connections to your tools.

Open-Source Model Deployment

Run open-weight models such as Llama or Mistral in environments you control.

Cloud and On-Premise Hosting

Deploy on AWS, Azure, Google Cloud, or your own infrastructure, sized for your latency and usage. Compare the options in our private LLM deployment guide.

Model Evaluation and Safety Testing

Test for hallucinations, bias, and prompt injection with automated evaluation and human review.

Data Pipelines and Preprocessing

Clean, structure, and enrich internal data so retrieval and fine-tuning start from reliable inputs.

LLMOps and CI/CD

Version, deploy, roll back, and monitor models and prompts through automated pipelines.

How It Works

How We Build Generative AI Solutions

Six steps from use case to a monitored production system.

  • 01

    Discovery and Use-Case Selection

    We map your goals, workflows, and data to find use cases where generative AI adds clear value, and we tell you when it does not.

  • 02

    Data Assessment and Model Selection

    We review your data and choose the model and approach (prompting, retrieval, fine-tuning, or a mix), from GPT, Claude, Llama, and others.

  • 03

    Prototype

    We build a working prototype on real examples so you can judge output quality early.

  • 04

    Development and Integration

    We build the full application: back end, user interface, retrieval, and integration with your systems.

  • 05

    Testing, Safety, and Evaluation

    We test against evaluation sets, run adversarial and edge-case tests, and add guardrails before launch.

  • 06

    Deployment and Monitoring

    We launch with monitoring and usage analytics, and keep improving prompts, data, and models over time.

Why Rain Infotech?

A technical partner that builds for production, not demos.

Founded in 2015, we combine AI and Blockchain engineering with hands-on technical leadership on every project.

Building Since 2015

Founded in 2015 in Surat, India, we have built web, mobile, blockchain, and AI systems for startups, SMEs, and enterprises.

AI and Blockchain Under One Roof

We build AI systems, blockchain platforms, and solutions that combine them, such as agents that work with smart contracts and on-chain data.

Custom & White-Label Solutions

Build from scratch, or start from a white-label product when a faster launch fits your plans.

Architecture and Security Before Code

We design data flows, integrations, permissions, and failure paths before writing code, so security is part of the first version.

Founder and CTO Involvement

Our technical leadership takes part in solution planning, so architecture decisions are made by people who build.

Transparent Communication

You see progress, open questions, and trade-offs as the project moves, from discovery to launch.

FAQs

FAQs About Generative AI Development

It builds applications on large language models and other generative models, such as chat and search over company data, content and document tools, assistants, and agents, along with the integration, evaluation, and deployment work needed to run them in production.

Internal knowledge assistants, customer-facing chatbots, document analysis and summarization, content generation tools, AI copilots inside your product, and agents that complete multi-step tasks.

Usually not. Most projects start with a pre-trained model plus retrieval over your existing documents. Fine-tuning needs a curated set of high-quality examples and is worth it when you need consistent behavior or format. See RAG vs fine-tuning.

Most products use both: a hosted or open-weight model, plus custom code for retrieval, integrations, guardrails, and the user interface. A fully custom model is rarely needed. When data cannot leave your environment, open-weight models can run on private infrastructure.

Timelines typically range from 3 to 10 weeks, depending on complexity, integrations, and whether fine-tuning is involved.

It can be, with the right design: access controls on what the model can retrieve, model providers whose terms do not allow training on your data, input and output filtering, activity logging, and private deployment where required.

Yes. We connect generative AI features to your CRM, SaaS product, website, or internal tools through APIs, SDKs, or custom interfaces.

We test outputs against evaluation sets, check for hallucinations and prompt injection, ground answers in your data with retrieval, and keep a human review step where errors are costly.
