The verdict in three sentences
Embedding generative AI in your workflows happens in two steps in Berlin in 2026: a POC at EUR 8,000-16,000, then production at EUR 20,000-55,000. The variable token cost (EUR 250 to 1,800/month) stays marginal against the target gain of -30% time on writing and extraction tasks. The real risk is not price; it is skipping the POC and the GDPR guardrails.
POC then production: two budgets to keep separate
A POC validates one use case on a narrow scope. Production adds guardrails, integration with business tools, human oversight and compliance. Conflating the two leads to disappointment.
| Phase | 2026 price (EUR) | Timeline | Typical content |
|---|---|---|---|
| Scoping and use case | 3,000 - 5,000 | 1 week | Prioritisation, target ROI measure |
| POC on 1 use case | 8,000 - 16,000 | 2-4 weeks | Prototype, prompts, quality evaluation |
| Production | 20,000 - 55,000 | 6-12 weeks | Tool integration, guardrails, oversight |
| Multi-use-case extension | +10,000 - 24,000 | +4-6 weeks | New processes, governance |
Running cost is tokens (model API) plus oversight. Budget for both.
| Recurring item | 2026 range | Note |
|---|---|---|
| Token / model API cost | EUR 250 - 1,800/month | By volume and model |
| Oversight and improvement | EUR 500 - 1,200/month | Prompt and quality review |
| AI integrator day rate | EUR 600 - 950 | Per task |
| GDPR / guardrails audit | EUR 2,000 - 5,000 | One-off |
Berlin vs Lyon: 2026 order of magnitude
In Lyon, production starts lower given day rates. 2026 estimates for a comparable scope.
| Item | Berlin (EUR) | Lyon (EUR) |
|---|---|---|
| POC | 8,000 - 16,000 | 5,000 - 12,000 |
| Production | 20,000 - 55,000 | 15,000 - 45,000 |
| AI integrator day rate | 600 - 950 | 480 - 780 |
| Monthly token cost | 250 - 1,800 | 200 - 1,500 |
Mini case study
Sabine, COO of a B2B services SME in Berlin (60 staff), wants to automate meeting minutes and contract-data extraction. She runs a POC at EUR 12,000, confirms -35% time, then goes to production for EUR 34,000 with EUR 800/month of tokens and oversight.
Calculation: 8 employees spend 6 hours/week on these tasks, totalling 48 hours/week. A 30% gain means 14.4 hours/week saved, about 62 hours/month. Valued at EUR 40/hour loaded, that is ~EUR 2,480/month of capacity recovered, quality aside. The total investment (EUR 46,000 + run) pays back in about 16 months, but the freed capacity is reallocated to billable work from month one.

FAQ
Do I really need a POC before production?
Yes. The POC (EUR 8,000-16,000) validates quality and real ROI before committing EUR 20,000-55,000. Skipping it multiplies failure risk.
Does my data go to the model vendor?
Not necessarily. You can choose non-retention offers with EU hosting. The GDPR audit (EUR 2,000-5,000) sets the contractual and technical frame.
What do tokens actually cost?
EUR 250 to 1,800/month for an SME. Cost depends on the volume of text processed and the model; caching and lighter models optimise it.
Which processes are the most profitable to automate?
Repetitive writing, document summaries and structured extraction. These are where the 30% gain materialises fastest.
Should a human stay in the loop?
Yes for any content with legal or client impact. Oversight (EUR 500-1,200/month) ensures quality and covers liability.
