End Users on Systems We Built

Generative AI pilots do not fail on capability. They fail on the four things nobody scopes.

A demo that impresses a leadership meeting is a low bar. The pilots that stall do so because nobody defined what "good enough to ship" means, nobody modelled cost at real volume, nobody tested what happens when the model is confidently wrong, and nobody owned it after the launch email. Our generative AI development process scopes all four before the build starts.

No definition of done

Traditional software is done when the feature works. Generative AI is done when output quality clears an agreed threshold on a representative test set. We define that threshold with you in week one, then measure every release against it.

Unmodelled unit economics

Token cost scales linearly with usage, and a feature that costs cents in a pilot can cost a serious monthly line item at production volume. We model cost per request during architecture, then control it with retrieval tuning, caching, model routing, and smaller models where quality allows.

Confident wrong answers

The failure mode is not a crash, it is a plausible answer that happens to be false. Grounding in your verified sources, citation of those sources, confidence thresholds, and adversarial testing turn that from an unbounded risk into a measured one.

Our Generative AI Development Services

Pixel Web Solutions builds nine categories of generative AI system, from retrieval-grounded knowledge applications to image and code generation pipelines. Each can run as a scoped proof of concept or a full production build.

Custom Generative AI Application Development

End-to-end applications with generative capability at the core, covering architecture, model selection, retrieval, application layer, and deployment.

LLM and RAG System Development

Retrieval augmented generation systems that answer from your documents with citations and permission-aware retrieval. See our RAG development services.

AI Copilot and Assistant Development

In-product copilots that draft, analyse and suggest next actions inside the interface users already work in. See our AI copilot development services. For conversational support interfaces specifically, see our AI chatbot development services.

Fine-Tuning and Custom Model Training

Parameter-efficient and full fine-tuning on your proprietary data, delivered through our AI model development services, where tone, format, domain vocabulary, latency, or cost targets cannot be met by prompting and retrieval alone.

Content Generation Systems

Production pipelines that draft, localise, and format content at volume, with human review gates, brand voice constraints, and factual grounding.

Document Intelligence and Summarisation

Ingestion, extraction, classification, and summarisation of contracts, claims, reports, and records, with confidence scoring and a review interface for exceptions.

Image, Video and Design Generation

Diffusion model pipelines for product imagery, creative variants, and design assets, including brand-consistent generation and rights-aware model selection.

Code Generation and Developer Tooling

Internal tools that generate, review, migrate, or document code against your own codebase and standards.

Generative AI Integration, Guardrails and Evaluation

Adding generative capability to an existing product, plus the safety layer around it: Input and output filtering, prompt injection defence and audit logging, formalised through our AI governance implementation service.

Already tried a pilot that stalled?

Send us what you built and where it stopped. Most stalled generative AI pilots fail on evaluation, cost, or data access rather than on the model, and those are fixable without starting again. We will tell you which one it is, free. If you are still deciding whether to build at all, start with our generative AI consulting services.

Prompt engineering, RAG, or fine-tuning: which approach your use case needs

Four approaches exist, and cost rises sharply across them. Start at the top of this table and only move down when the approach above genuinely fails your requirement. Most business use cases are solved by retrieval augmented generation.

Approach What it does Best for Cost and effort Main limitation
Prompt engineering Instructs a hosted model without changing it Well-defined tasks, general knowledge, fast validation Lowest Cannot add knowledge the model does not have
Retrieval augmented generation (RAG) Retrieves your content and grounds the answer in it Anything needing company knowledge, documents, or current data Moderate Depends on source content quality and retrieval design
Fine-tuning Adapts a model on your examples Where a hosted model will not meet your residency, latency or cost targets, our large language model development company covers open-weight and self-hosted routes. High, plus retraining Does not reliably teach facts, and needs a curated dataset
Continued pretraining Trains on large proprietary corpora Genuinely novel domains, rare in commercial work Highest Needs very large data volume and budget

Note: Fine-tuning is the most commonly over-prescribed approach in this industry. It changes how a model responds, not what it knows, so a fine-tune will not fix a hallucination problem that retrieval would solve for a fraction of the cost. We often recommend combining retrieval with a small fine-tune, and sometimes we recommend neither.

Our generative AI development process, from use case to production

Generative AI development runs in six stages: use case and success criteria, data and content readiness, approach and model selection, prototype with evaluation harness, guardrails and hardening, then deployment with cost and quality monitoring.

Use case and success criteria

week 1 : Define the outcome, the baseline it must beat, and the measurable quality bar for shipping. Deliverable: a scoped use case with an agreed definition of done.

Data and content readiness

weeks 1 to 2 : Audit the documents, databases, and examples the system will draw on, including access rights, permissions, freshness, and gaps. Deliverable: a prepared knowledge source and a gap list.

Approach and model selection

week 2 : Benchmark candidate models and approaches against your accuracy, latency, and cost per request targets, using your own test cases rather than public leaderboards. Deliverable: a recommended architecture with modelled unit economics.

Prototype and evaluation harness

weeks 3 to 6 : Build the working system alongside a golden test set and automated scoring, so quality is a number rather than an opinion. Deliverable: a prototype on your data with measured performance.

Guardrails and hardening

weeks 6 to 8 : Input and output filtering, prompt injection defence, PII handling, refusal behaviour, fallback paths, rate limiting, and adversarial red teaming. Deliverable: a release-ready system with a documented risk assessment.

Deployment, monitoring and iteration

ongoing : Production deployment in your cloud or ours, quality and cost dashboards, drift and regression detection, feedback capture, and a scheduled improvement cycle.

Why Choose Pixel Web Solutions for Generative AI Development

Model agnostic, and provably so

We benchmark GPT, Claude, Gemini, Llama, Mistral, and open-weight models against your own test cases. No reseller relationship decides your architecture, and the system is built so a model can be swapped without a rewrite.

Evaluation before opinion

Every build ships with a golden test set and automated scoring. Quality is reported as a measured number against an agreed threshold, not as a demo that went well.

Unit economics engineered in

Cost per request is modelled during architecture and monitored in production, controlled through retrieval tuning, caching, model routing, and using the smallest model that clears the quality bar.

Your data stays yours

Enterprise API tiers and self-hosted open-weight deployment mean your data is not used to train third-party models. Private cloud and on-premise options where data cannot leave your environment.

Guardrails as a build stage, not a patch

Prompt injection defence, output filtering, PII redaction, refusal behaviour, and audit logging are scoped as their own stage with their own deliverable.

Full ownership

Source code, prompts, retrieval pipelines, fine-tuned weights, evaluation sets, and documentation transfer to you. No lock-in to a proprietary Pixel layer.

Generative AI vs traditional AI, and when each one is right

Traditional AI predicts or classifies from existing data. Generative AI produces new content. Traditional AI is the better tool for scoring, forecasting, and detection, and using a language model for those tasks is usually slower, more expensive, and less accurate.

Factor Traditional AI and machine learning Generative AI
Output A prediction, score, or label. New text, image, code, or structured content.
Best for Forecasting, fraud detection, recommendation, classification. Drafting, summarising, answering, transforming, creating.
Training data Historical labelled data, usually required. Often none needed to start, since foundation models are pretrained.
Determinism Same input gives same output. Output varies within a range.
Running cost Mostly fixed infrastructure. Variable cost per request.
How you evaluate Precision, recall, accuracy against ground truth. Graded quality against a golden set, plus human review.
Time to first version Weeks to months, gated by data. Days to weeks, gated by content readiness.

Many production systems use both. If your use case is prediction rather than generation, start with our AI development services instead, and we will point you to the cheaper approach.

Cost, data ownership and rights to generated output

What drives generative AI running cost

Four things: how many requests you serve, how much context each request sends to the model, which model tier handles it, and how much of the workload can be cached or routed to a smaller model. Cost is designed, not discovered. We model it at realistic volume before the build and monitor it after launch.

Will our data train someone else's model?

Not on enterprise API tiers, where providers contractually exclude business inputs from training. Where that assurance is not sufficient, we deploy open-weight models inside your own environment so the data never leaves it. Which route applies to you is decided during scoping, not after.

Who owns what the system generates?

You own the source code, prompts, retrieval pipelines, fine-tuned weights, and evaluation sets. Ownership of the generated output itself is governed by the model provider's terms and by copyright law in your jurisdiction. Purely machine-generated work can have weaker copyright protection than human-authored work in several jurisdictions including the US. For content where exclusivity matters commercially, we design a human-in-the-loop step so there is meaningful human authorship in the final work. This is a legal question as much as a technical one, and your counsel should confirm the position for your market. We flag it during scoping rather than after launch.

How much do generative AI development services cost?

Build cost is driven by content readiness, which approach the use case needs, integration depth, and compliance requirements. Running cost is separate and scales with usage. We quote a fixed band per milestone after the free scoping call, and we model the running cost alongside it so you see both numbers before committing.

Engagement What it covers Typical timeline
Proof of concept One use case, your data, measured against a baseline. 3 to 5 weeks.
Production build Live system, evaluation harness, guardrails, monitoring. 8 to 16 weeks.
Fine-tuning engagement Dataset curation, training, evaluation, deployment. 4 to 8 weeks.
Enterprise programme Multiple use cases, private deployment, compliance, platform layer. 4 months and up.
Optimisation retainer Quality tuning, cost reduction, model updates, new use cases. Monthly.

Budget two numbers, not one. Build cost is a project. Inference and infrastructure cost is an operating line item that scales with adoption, which is why we model it before you approve the build.

Frequently asked questions

Generative AI development services cover the design, build, evaluation, and deployment of systems that generate new content using large language or diffusion models. Typical scope includes use case definition, preparing your data and documents, choosing between prompting, retrieval, and fine-tuning, building an evaluation harness, adding guardrails, and deploying with cost and quality monitoring.

Traditional AI predicts, classifies, or scores based on historical data. Generative AI produces new text, images, code, or structured content. For forecasting, fraud detection, and recommendation, traditional machine learning is usually faster, cheaper, and more accurate. For drafting, summarising, answering, and transforming, generative AI is the right tool.

There are two costs. Build cost is driven by content readiness, the approach required, integration depth, and compliance needs, quoted as a fixed band per milestone. Running cost is separate and scales with usage, driven by request volume, context size, model tier, and how much is cached or routed to cheaper models. We model both before the build starts.

A proof of concept typically takes 3 to 5 weeks, a production build 8 to 16 weeks, and a fine-tuning engagement 4 to 8 weeks. The largest variable is content readiness. Projects with clean, accessible, well-structured documentation move roughly twice as fast as projects that need content prepared first.

Use retrieval augmented generation when the system needs to know your information, which covers most business use cases. Use fine-tuning when you need consistent tone or format, domain-specific vocabulary, lower latency, or acceptable quality from a smaller and cheaper model. Fine-tuning changes how a model responds rather than what it knows, so it does not fix a knowledge gap that retrieval would solve more cheaply. Many production systems use both.

The right model depends on your accuracy, latency, cost, and data residency requirements, and it should be chosen by benchmarking against your own test cases rather than public leaderboards. We build with a model abstraction layer so the underlying model can be swapped without rewriting the application, which matters because pricing and capability in this market change every few months.

Not always. Many generative AI applications launch on documentation, product content, policies, or public data you already have. Fine-tuning needs a curated set of example inputs and outputs, typically hundreds to thousands depending on the task. Where the data does not exist yet, we scope its creation as the first milestone. rather than stalling the project.

Through grounding, evaluation, and guardrails. Answers are retrieved from verified sources with citations. Every release is scored against a golden test set to catch regressions. Confidence thresholds route uncertain cases to a human, structured outputs are schema-validated, and adversarial testing checks prompt injection and edge cases.

Not on enterprise API tiers where providers contractually exclude business inputs from training. Where a contractual assurance is not enough, for example under strict data residency or regulatory requirements, we deploy open-weight models inside your own cloud or on-premise so data never leaves your environment.

You own the code, prompts, pipelines, fine-tuned weights, and evaluation sets outright. Rights to generated content itself depend on the model provider's terms and on copyright law in your jurisdiction. Purely machine-generated work receives weaker protection than human-authored work in several jurisdictions including the US. Where exclusivity matters commercially, we design meaningful human review and editing into the workflow. Confirm the position with your own legal counsel.

By agreeing a quality bar before the build and measuring against it. We create a golden test set of representative inputs with expected outputs, score every release automatically, track human review and escalation rates, and monitor latency and cost per request. A release ships when it clears the agreed threshold. not when a demo goes well.

Model updates and deprecations, content and knowledge base refreshes, prompt and retrieval tuning, cost optimisation, regression testing against the golden set, and monitoring for quality drift. Most clients run this as a monthly retainer, though everything needed to run it in-house is documented and handed over.
