How Long Does a Generative AI Project Take? A Realistic Timeline from Discovery to Production
Most focused generative AI projects take 6 to 12 weeks from discovery to production. More complex builds usually need 12 to 24 weeks. These ranges assume your data and decision-makers are available when needed. Data preparation, integration, and testing take up most of the time. Building the model is often the quickest part. If your project is regulated or customer-facing, expect extra review time.
If you’re comparing vendors, you’ve probably seen a wide range of timelines. So what does a realistic generative AI project schedule look like? Here’s a breakdown of each phase, what can slow things down, and how to keep your project moving.
These ranges match our published delivery estimates. We’ll flag which numbers are based on our own experience, so you know what’s published and what’s our judgment.
A focused generative AI project, such as a customer support chatbot or document intelligence tool, usually takes 6 to 12 weeks from discovery to production. More complex builds, like enterprise LLM fine-tuning, large RAG systems, or multi-agent workflows, often take 12 to 24 weeks.
Regulated or customer-facing projects need extra time for legal and security reviews. These can push the timeline past 24 weeks. Use the table below as a starting point, and adjust for your own risk level.
Project type | Typical timeline, discovery to production | Where the number comes from |
|---|---|---|
Focused application, such as a support chatbot or document intelligence | 6 to 12 weeks | Cynoteck delivery range |
AI agent built on a platform you already use, such as Salesforce | 4 to 6 weeks | Two Cynoteck case studies |
Complex RAG system, LLM fine-tuning, or multi-agent platform | 12 to 24 weeks | Cynoteck delivery range |
Customer-facing or regulated, high-stakes use | Often more than 24 weeks | Our estimate |
Working prototype | 3 to 4 weeks | Cynoteck agile delivery |
Table 1. Generative AI project durations by project type. Ranges assume timely access to data, systems, and decision-makers.
We deliver prototypes early on purpose. With agile delivery, you review real outputs within three or four weeks instead of waiting for a big reveal at the end.
A generative AI project moves through six phases: discovery, planning, data and model work, integration, testing, and deployment. Some phases overlap, which helps shorten the schedule.
Phase | Focused build | Complex build | What happens |
|---|---|---|---|
1. Discovery and AI readiness assessment | 1 to 2 weeks | 2 to 3 weeks | We review goals, data, and current systems |
2. Use case planning and architecture | About 1 week | About 2 weeks | We pick the AI approach and plan pipelines and integrations |
3. Data preparation and model development | 2 to 3 weeks | 4 to 7 weeks | We clean data and build prompts, retrieval (RAG), or fine-tuning, plus the first prototype |
4. Integration and implementation | 1 to 2 weeks | 3 to 5 weeks | We connect the AI to your systems through secure APIs |
5. Testing, validation, and QA | 1 to 2 weeks | 2 to 4 weeks | We test accuracy, edge cases, and security |
6. Deployment and monitoring | About 1 week | 1 to 2 weeks | We go live and start tracking performance |
Total, with overlap | 6 to 12 weeks | 12 to 24 weeks | Matches the ranges in Table 1 |
Table 2. Planning ranges for each phase. The phase names follow our six-step process. The durations are our planning estimates, and the totals match our published ranges.
Discovery: First, we check if the use case is worth building. We review your goals, data, and systems, and agree on how to measure success. Skipping discovery rarely saves time, since unclear goals often lead to rework later.
Planning and architecture: Here, we pick the right AI approach and design the data pipelines and integrations. Early validation helps avoid building something that doesn’t fit your needs.
Data preparation and model development: Data quality drives system performance. In this phase, we collect, clean, and organize your data, then build and refine the model, prompts, or retrieval layer. You’ll see the first working prototype here.
Integration: The AI solution must fit into your existing workflows, or you won’t use it. We connect it with secure APIs and scalable infrastructure. Well-documented APIs speed things up, while older or fragile systems can slow the process.
Testing and validation: Before launch, we test performance, accuracy, and edge cases. We also check for prompt injection, model poisoning, and model hijacking. Because generative systems can sound convincing but still be wrong, this phase builds trust in the results.
Deployment and monitoring: After go-live, we monitor performance and make adjustments as needed. Models need regular updates to stay accurate, so this phase continues after launch.
In a 10-week focused build, you’ll see the first prototype by week four and go live in week ten. Your own schedule will depend on your data and systems.
Weeks | Milestone | What you’ll see |
|---|---|---|
1 | Discovery kickoff and data access | Questions, sample data requests, and a stakeholder map |
2 | Readiness findings and success metrics | A short findings summary and an agreed baseline |
3 | Architecture and plan approved | The design, integration list, and risks |
3 to 5 | Data preparation and first prototype | A working demo by week four, on your real data |
6 to 7 | Integration with your systems | The AI running inside your workflow |
8 to 9 | Testing, security checks, and fixes | Accuracy results and edge-case handling |
10 | Go-live and monitoring | A live system, with performance tracking switched on |
Table 3. Illustrative week-by-week plan for a focused build. It fits within the 6- to 12-week range in Table 1.
Some phases overlap in this schedule, which helps shorten the project. How well that works depends on how quickly you can provide access to data.
The biggest delays in generative AI projects come from data readiness, integration challenges, review cycles, and slow decisions. These depend on your environment, so even similar projects can finish weeks apart.
Factor | Speeds you up | Slows you down |
|---|---|---|
Data | Organized, current, and already accessible | Scattered files, old scans, and unclear permissions |
Integrations | Documented APIs and test accounts | Legacy systems and missing access |
Quality bar | Internal assistant with human review | Customer-facing answers with liability |
Security and compliance | Legal and security join at discovery | Review starts after the build |
Decisions | One accountable owner with quick approvals | Committees and slow sign-off |
Scope | One use case at a time | Many use cases bundled together |
Table 4. What speeds up or slows down a generative AI project. This reflects our delivery judgment.
Independent research backs this up. In July 2024, Gartner predicted that teams would abandon at least 30% of generative AI projects after proof of concept by the end of 2025. They pointed to weak data, thin risk controls, rising costs, and unclear business value. These issues match what we see in practice.
A proof of concept shows the idea works. A pilot proves it works for real users. Production means it works reliably every day. Some teams skip the pilot, but that step catches problems before they reach more users. Mixing up these stages is a common reason projects run late.
Stage | What it proves | Data | Users |
|---|---|---|---|
Proof of concept or prototype | The approach can produce useful outputs | Real samples from your business | A small test group |
Pilot | The system holds up in daily work | Live data with limits | A defined group of real users |
Production | The system is reliable, secure, and monitored | Full data with access controls | Everyone it’s built for |
Table 5. Three stages of a generative AI project.
Design your prototype for production from the start. Use real data, set a clear success metric, and build a test set early. Otherwise, you risk ending up with a demo that looks good but needs a major rebuild. That gap is where many projects stall.
For example, our case studies show agents going live on Salesforce in four to six weeks. Here are three projects and their reported results.
Project | Timeline | Reported result |
|---|---|---|
Concept to live in four weeks | Repetitive queries automated, with smart escalation to human agents | |
Concept to live in six weeks | Human-agent calls fell by 80% | |
96% accuracy in the first month after go-live | Manual review effort fell by 80% |

Both agents ran on Salesforce. In the six-week project, the team built on the client’s existing setup, which kept integration short. Your schedule will depend on your own systems, so use these examples as proof that fast delivery is possible, but expect your numbers to vary.
The time needed for compliance and security review depends on your use case, so plan for it from the start. For many projects, legal and security work takes a few weeks and can run alongside development. In regulated or customer-facing projects, this review can become the longest part of the schedule.
Two rules shape the work for teams that serve people in the EU. First, the AI Act’s transparency rules took effect in August 2026. They require chatbots to tell people they’re talking to a machine, and they require AI-generated content to be identifiable. Second, the European Commission says stricter rules for high-risk uses, such as employment and education, start on December 2, 2027.
On the security side, we start with early design choices. Our projects use encryption, role-based access, and private model deployments to keep your data out of outside providers’ training sets. Healthcare projects also get a HIPAA-compliant architecture. Bringing your legal and security contacts into discovery helps avoid late surprises that can delay projects.
We need six things from your team, and most take little time up front. Missing any of them won’t stop the project, but it will likely push your date back. Use these as a quick readiness check.
One accountable owner: Someone who can approve scope and decide on trade-offs when they come up.
Early access to data and systems: Sample documents, API access, and test accounts in the first week.
A few subject-matter experts: They judge outputs and help build the test set.
A security and legal contact: One person who can review the design early.
A success metric with today’s baseline: Otherwise nobody can say whether the system works.
Quick approvals: Agree on response times before kickoff.
Not sure how ready your team is? Use an AI readiness checklist to spot gaps before you start. If you find major gaps, a short consulting phase may be the better first step.
Answer six yes-or-no questions and count your “no” answers. Each “no” is a risk that could add time to your project. This is just a rule of thumb, so use it as a rough guide.
Question | Why it matters |
|---|---|
Is the data you need in one place, and can we access it now? | Scattered data is the most common source of delay |
Do the systems we must connect have documented APIs? | Legacy systems add integration time |
Does the project cover one use case? | Bundled use cases stretch every phase |
Will only your own staff use it at first? | Customer-facing launches need more review |
Is a security or legal contact named? | Late review adds weeks |
Can your owner approve decisions within a couple of days? | Slow sign-off stalls the whole plan |
Table 7. Six-question schedule self-check. A rule of thumb from our delivery judgment.
If you answer “no” zero or one times, expect your project to land at the low end of the range; with two or three, plan for the middle. With four or more, expect the high end or even longer. The most accurate estimate comes after discovery, once we review your data.
You can shorten your schedule by focusing on a single use case, reusing existing systems, and starting early work in parallel. Never skip testing or security review to save time. Here are the tactics that work.
Start with one use case: A focused build fits the 6- to 12-week range. Bundled use cases don’t.
Build on what you already run: For example, a six-week project used the client’s existing Salesforce setup.
Work in parallel: Start data access and security review during discovery, so both are ready when the build begins.
Build the test set in week one: Early testing reveals problems while they’re still easy and inexpensive to fix.
Demo progress every one or two weeks: Seeing real outputs helps keep decisions moving.
Roll out in phases: Start with a pilot group, then widen access once the results hold up.
If a plan gets shorter because someone skipped testing, you haven’t really saved anything. The risk just shifts to your customers.
Be cautious of any proposal that skips discovery, skips testing, or promises a delivery date before reviewing your data. Reliable plans have clear phases and dependencies. Watch for these warning signs in an estimate.
No discovery or readiness phase. The vendor jumps straight to building.
No testing or evaluation phase. Nobody plans to measure accuracy.
A fixed date before seeing your data. The date can’t be reliable yet.
“Production in two weeks” for a complex build. Integration and review take longer than that.
No mention of security or compliance. It will show up later as a delay.
No prototype until the end. You can’t judge progress.
No post-launch plan. Models need monitoring and updates.

A longer schedule usually costs more, since more weeks mean more team effort. Scope drives both cost and schedule, so a narrow first release helps you control both.
We build the plan around your data, systems, and risk level, and confirm it as the project progresses. The generative AI development process has six steps: discovery and readiness assessment, use case planning and architecture, data preparation and model development, integration, testing and validation, and deployment with ongoing optimization.
With agile delivery, you see working prototypes within the first three or four weeks. This way, you evaluate real outputs throughout the project instead of waiting on slide decks. Testing covers prompt injection, model poisoning, and model hijacking before anything goes live.
Every project is different, so a general range only goes so far. A short conversation about your data, systems, and risk level gives you a much clearer answer. You’ll see what a realistic schedule looks like and where you can safely save time.

In our delivery approach, you’ll see a working prototype within the first three to four weeks. Quotes elsewhere vary, so check that any prototype runs on your real data.
A focused chatbot, like a customer support assistant, usually takes 6 to 12 weeks from discovery to production. However, integrations and your quality standards can extend that range.
It depends on your data. A focused document intelligence build can fit within 6 to 12 weeks, while complex RAG knowledge systems usually take 12 to 24 weeks.
Enterprise-grade LLM fine-tuning projects usually take 12 to 24 weeks, including data preparation, testing, and deployment.
It varies by project, but data preparation and integration usually take the longest. Both depend on your environment, so early access to data and systems helps the most.
Most delays come from data readiness, integration issues, slow approvals, or late security review. Gartner’s research on abandoned projects also points to weak data and thin risk controls as common causes.
No. The estimate ends at production. Monitoring and optimization continue after go-live, since models need regular updates to stay accurate.
Sometimes. Two of our Salesforce-based agents went live in four and six weeks. Platform tools can limit flexibility, so balance speed with your long-term needs.
If you serve people in the EU, chatbots must tell users they’re talking to an AI. These rules took effect in August 2026. High-risk uses face stricter rules starting December 2, 2027. Add time for legal review to your plan.
