Generative AI Development Company
NextSolves is a generative AI development company that turns LLM capabilities into production-grade software products. We build AI agents, retrieval-augmented generation pipelines, custom chatbots, and AI-assisted workflows using OpenAI GPT-5.6, Claude, and open-source models.
Outcomes
What you get with this service
Model-Agnostic Engineering
We work across OpenAI, Anthropic Claude, Mistral, and open-source models. We recommend the right model for each use case based on latency, cost, and capability — not vendor loyalty.
Production AI Agents
We build multi-step AI agents with tool use, memory, and error recovery — not just single-shot prompts. Agents that can browse, call APIs, write code, and route decisions through structured logic.
RAG Systems That Actually Work
Retrieval-augmented generation is only as good as its chunking strategy, embeddings choice, and retrieval logic. We design RAG pipelines that return accurate, grounded answers — not hallucinated ones.
Secure Data Handling
We build AI systems that respect data boundaries. Sensitive documents never leave your infrastructure unless you choose to send them. We implement access controls and audit logging from the start.
Evaluation-Driven Development
LLM outputs are non-deterministic. We build evaluation frameworks alongside features so you can measure quality degradation, catch regressions, and make model or prompt changes with confidence.
Integrated into Your Product Stack
AI features ship as part of your existing product — not bolted on via a third-party widget. We integrate AI capabilities into Next.js frontends, REST APIs, and backend services you already own.
Audience
Who this is for
Senior engineering for teams that need ownership and speed — not agency theatre.

Process
How we deliver
A clear path from idea to production — scoped early, demoed often, handed over cleanly.
- 01
Use Case Validation & Feasibility
We start by stress-testing your AI use case against real LLM behaviour. Many ideas that sound straightforward hit model limitations, latency constraints, or accuracy problems in practice. We identify these early and design around them before committing to a build.
- 02
Prompt Architecture & Data Pipeline Design
We design the system prompt structure, tool schemas, retrieval pipeline, and context management strategy. For RAG systems, this includes chunking design, embedding model selection, vector store configuration, and re-ranking logic.
- 03
Iterative Build with Eval Benchmarks
We build in cycles, with an evaluation dataset growing in parallel with features. Every significant change to prompts, retrieval logic, or model configuration is measured against the benchmark before shipping.
- 04
Deployment, Monitoring & Handover
We deploy AI systems with structured logging, cost tracking, and latency monitoring. You get observability into what your AI is doing and spending — not a black box. We document the system thoroughly so your team can maintain and extend it.

FAQ
Questions teams ask before starting
Still unsure? Book a discovery call and we'll map the right approach.
What does a generative AI development company actually build?+
We build software products and features powered by large language models. That includes custom AI chatbots, AI agents that take multi-step actions, document intelligence tools, AI-assisted search, code generation tools, and workflow automation systems. Everything we build is production-grade — deployed, monitored, and maintainable.
How is NextSolves different from using a no-code AI tool or a generic automation platform?+
No-code tools work until your use case outgrows them. We build custom AI systems that fit your exact data, workflow, and user experience requirements. That means custom retrieval pipelines, fine-tuned prompts, domain-specific tool integrations, and output schemas designed around your product — not a generic template.
Can you build AI agents for specific business workflows?+
Yes. AI agent development is one of our core capabilities. We build agents that can call external APIs, query databases, process documents, send structured outputs, and make conditional decisions — all orchestrated through frameworks like LangGraph or the OpenAI Assistants API. We design for reliability and observability, not just demo-ability.
Which AI models do you work with?+
We work primarily with OpenAI GPT-5.6 and Anthropic Claude, and select the model based on your use case's accuracy, latency, and cost requirements. For applications where data privacy or cost is a constraint, we also work with open-source models deployed on your own infrastructure.
How do you handle accuracy and hallucination in AI outputs?+
We treat accuracy as an engineering problem, not a model problem. Our approach includes grounding outputs in retrieved source documents (RAG), using structured outputs and function calling to constrain response shape, building evaluation datasets to benchmark quality, and adding human review checkpoints for high-stakes decisions. We don't ship AI features without a plan for measuring and improving accuracy.
What does an AI development project cost and how long does it take?+
A focused AI feature — a chatbot with RAG over a specific document corpus, for example — typically runs four to eight weeks. A multi-agent workflow system or AI-native SaaS product can take three to five months. We scope every project individually because LLM complexity varies widely, and we'd rather give you an honest estimate than a low number that grows in production.
