A useful AI training program in a business runs from 1 to 5 days depending on the target outcome, with 2 days in person as the standard for operational deployment. Most awareness sessions fit into 7 hours (1 day); hands-on programs into 14 hours (2 days); rollouts with internal champions into 21 to 35 hours (3 to 5 days). Anything shorter than 3 hours is awareness only and does not lastingly change practices.

AI training for businesses in France costs between €350 and €3,300 ex. VAT per person in 2026, with up to 100% OPCO funding for SMEs under 50 employees. Since August 2, 2026, the EU AI Act requires every company using ChatGPT, Claude, or Copilot to guarantee minimum AI literacy across its teams, with sanctions up to €7.5M or 1.5% of global annual turnover. Here is how to design a truly operational, funded, and compliant program.

This article breaks down durations by objective, explains why a 2-hour conference is no longer enough since Article 4 of the EU AI Act started applying, and shares the framework GrowthPerf uses to size AI training that truly serves an SME.
For the full picture (funding, Qualiopi certification, AI Act timeline), see our complete guide to AI training for business. For the cost of each format, see AI training pricing in 2026.
The right reflex is to start from the business objective, not from a number of hours. Three variables shape AI training duration: the goal (understand, practice, deploy), the audience profile (executives, operational teams, technical staff) and the regulatory context set by Article 4 of the AI Act.
The first factor is the learning objective. Pure awareness, meant to build shared vocabulary and reduce fear, fits in 1 day. Operational uptake, where each participant leaves with 2 or 3 business use cases ready to industrialize, takes 2 days. A structured rollout with internal champions needs 3 to 5 days spread across several weeks.
The second factor is the audience profile. Executives and steering committee members benefit from short formats (4 to 7 hours) focused on strategic reading and governance. Operational teams (marketing, sales, HR, finance) need at least 14 hours to translate AI into measurable productivity gains. Technical profiles (developers, data analysts) follow paths of 35 to 75 hours, or 150 to 450-hour bootcamps for real data science upskilling.
The third factor, often overlooked, is the AI Act itself. Since 2 February 2025, Article 4 requires a sufficient level of AI literacy for any staff member dealing with an AI system. The European Commission does not set a minimum duration, but documented training effort becomes enforceable from 3 August 2026, when national market surveillance authorities will be able to inspect and sanction.
The 1-day format is the most requested by SMEs: it sets the foundations, defuses fear and builds a shared vocabulary. It targets executives, managers and teams discovering generative AI. Seven hours are enough to cover: what a large language model is, how to write a useful prompt, which tools matter (ChatGPT, Claude, Gemini, Copilot 365), and which guardrails to apply to data.
This format also meets the minimum bar of Article 4 of the AI Act for staff lightly exposed to AI. It documents a structured approach, which is exactly what the European Commission expects in case of inspection.
The limit of the 1-day format: it triggers discovery, it does not transform practices. Without a follow-up mechanism (microlearning, J+30 workshop, internal community), 50 to 70 % of the content is forgotten within the first 24 hours, in line with the Ebbinghaus forgetting curve. A 1-day program sold without follow-up is therefore a risky purchase.
Indicative cost for in-company training of up to 8 people: 1,800 to 3,200 € excl. VAT depending on the trainer and customization level.
The 2-day format is the standard for converting curiosity into productivity. Day 1 covers fundamentals; day 2 dedicates time to guided experimentation on the participants' real use cases: commercial emails, meeting note analysis, automatic minute generation, simple workflow automation, knowledge base structuring.
It is also the format that maximizes the learning to cost ratio. According to educational research, a 3-day in-person program reaches around 60 % retention versus 10 % for a one-shot conference; 2 well-designed days, with hands-on exercises every 90 minutes, capture most of that effectiveness while remaining compatible with SME schedules.
The 2-day format can be structured in several ways:
This format is typically priced between 3,500 and 6,500 € excl. VAT in company (up to 10 people). It is eligible for the French skills development plan and fundable by your OPCO, provided the training organization is Qualiopi certified.
Beyond 2 days, we no longer talk about training but about deployment programs. Three to five days spread over 1 to 3 months allow you to build a core of internal AI champions (1 per group of 10 staff), set a usage policy, and launch the first 3 to 5 automation or AI agent projects.
Typical structure of a 5-day path:
This format targets companies that have already crossed the awareness step and want to industrialize. The budget runs from 8,000 to 18,000 € excl. VAT in company, generally eligible for OPCO funding and, in certain cases, for the French FNE-Formation scheme for SMEs in transition.
To turn a non-technical employee into a data analyst capable of building AI solutions, plan for 150 to 450 hours. These programs, usually spread over 3 to 7 months, are eligible for the French CPF when they lead to a recognized certification.
These formats stay marginal at SME scale: they concern one or two profiles per company, not the whole staff. For the audiences we support (SMEs 10 to 250 employees, associations, B2B services), the priority is to first align 100 % of teams on 1 or 2 days of practical awareness, then specialize 2 or 3 champions.
Conversely, 1 to 3-hour conferences and webinars carry no measurable pedagogical value: their retention caps at 10 % and they do not cover Article 4 obligations. They can serve as a commercial hook or HR event, never as an answer to a real training need.
70 % of training content is forgotten within 2 weeks if nothing is done to anchor the learning. That is what Hermann Ebbinghaus' forgetting curve shows, confirmed by every modern cognitive science study.
Practically, a 2-day AI training without anchoring produces, 1 month later, a practice level equivalent to 25 % of what was taught. That is why we always add to in-person time 3 inexpensive mechanisms:
With these 3 mechanisms, retention rises from 25 % to 60 or 70 %. The added cost is low (500 to 1,500 € excl. VAT) and the return on investment far exceeds that of an extra day of training.
The AI Act does not set a minimum duration; it requires a documented, risk-adjusted approach. Article 4, in application since 2 February 2025, requires every AI provider and deployer to ensure a sufficient level of AI literacy for staff and for any person acting on their behalf.
Key points for SMEs:
For high-risk AI systems (Annex III of the regulation), Article 26 additionally requires training sufficient to ensure human oversight. This typically applies to AI tools used in HR (CV screening), finance (credit scoring) or security.
| Goal | Recommended duration | Target audience | Covers AI Act art. 4 |
|---|---|---|---|
| Brief an exec committee | 4 hours (half day) | Executives, managers | Yes, if documented |
| Build awareness across a team | 7 hours (1 day) | Non-technical staff | Yes |
| Make a team operational | 14 hours (2 days) | Marketing, sales, HR, finance | Yes, reinforced |
| Roll out with internal champions | 21 to 35 hours (3 to 5 days) | Extended teams, structured project | Yes, advanced |
| Train an internal AI champion | 35 to 75 hours (1 to 2 weeks) | Future facilitators | Advanced, documented |
| Data or AI career switch | 150 to 450 hours (bootcamp) | Technical profiles in transition | Expert level |
Simple rule: the higher the risk of the AI system in use, the longer and deeper the training must be. ChatGPT use for commercial emails warrants 1 day; an HR scoring tool warrants a dedicated path.
GrowthPerf, a Qualiopi certified training organization, builds every program on a 30-minute audit grid that determines the right duration, never more, never less. We cross-reference current AI maturity, in-scope functions, regulatory risk and available budget (skills development plan, OPCO, FNE).
Our standard formats: 1 day of awareness for exec committees and discovery teams, 2 in-company days to shift into business practice, and a 5-day program spread over 3 months for deployments with internal champions. All our programs include a D+30 follow-up workshop at no extra cost.
To calibrate the right duration for your team, book a free 30-minute AI training audit. You leave with a costed program and a financing plan that fits your situation.
What is the legal minimum duration of AI training in business? No minimum duration is fixed by law. Article 4 of the AI Act requires a sufficient level of AI literacy, adjusted to context and risk, but leaves the format open. In practice, below 7 hours (1 day), it becomes hard to document a serious effort if national authorities start inspecting from 3 August 2026.
Can AI training be done in 1 hour or via webinar? 1 to 3-hour webinars serve as awareness or internal marketing, but their retention caps at 10 % and they do not cover AI Act obligations. They do not replace real training but can effectively precede it.
Is it better to schedule 2 consecutive days or 2 spaced days? 2 spaced days (D and D+15) are pedagogically more effective, because participants return with questions from practice. 2 consecutive days are better when collective dynamic is the priority (new team, transformation project).
How is AI training funded depending on duration? Formats up to 35 hours fall under the skills development plan, fundable by your OPCO. Beyond that, certifying paths can mobilize the CPF. The French FNE-Formation scheme can complement funding for SMEs in economic transition.
How many hours per week should I practice after training? A daily 30-minute practice is enough to anchor the learning and to cut by around 40 % the time needed to reach an operational level. Without this practice, forgetting kicks back in by week 2.
Is a 1-day AI training enough for the AI Act? Yes, provided it is documented (program, attendance, certificate) and covers the fundamentals: understanding AI, risks, opportunities, internal legal framework. For high-risk AI systems, a longer specialized program is needed, pursuant to Article 26.
What duration for an executive or board member? A half day (4 hours) is enough for an executive already exposed to AI, with a format focused on strategic reading, governance and cross-functional use cases. For a beginner executive, plan for a full day.
