- [Local LLM hardware calculator](https://dubir.net/tools/local-llm-hardware-calculator/): Which open LLMs fit on a given GPU, Mac or VRAM budget and goal (chat, coding, document and passport OCR with vision models), at which quantisation, with what context length and roughly what tokens/second, alongside each model's Terminal-Bench 2.1 agent score.

## Guides

Written and maintained by Evdokiia Petrovskaia, director of Dubir Group Limited. Every tax figure carries its source and the date it was last checked; every hardware figure is an estimate from published specifications.

- [Guides](https://dubir.net/guides/): Cyprus tax and payroll explained line by line, and what it takes to run open language models on your own hardware.
- [Cyprus vs Malta vs Dubai tax 2026](https://dubir.net/guides/cyprus-vs-malta-vs-dubai-tax/): The same EUR 200,000 of profit run through all three regimes. Cyprus corporate tax is 15% from 2026, Malta's 35% refunds to an effective 5% on distribution, and the UAE charges 0% to AED 375,000 then 9%.
- [Cyprus expat tax exemptions](https://dubir.net/guides/cyprus-expat-tax-exemptions/): The 50% exemption (over EUR 55,000, 17 years), the 25% repatriation exemption (over EUR 30,000, 7 years) and the 20% exemption (capped at EUR 8,550, 7 years), which the March 2026 law did not close. What each is worth on a real salary.
- [Cyprus employer contributions 2026](https://dubir.net/guides/cyprus-employer-contributions/): 15.4% on top of gross pay, broken into social insurance 8.8%, GESY 2.9%, redundancy 1.2%, industrial training 0.5% and social cohesion 2%. Which are capped at the EUR 68,904 ceiling and which are not.
- [VAT on property in Cyprus](https://dubir.net/guides/cyprus-vat-on-property/): When a home is charged 5% and when 19%, with the 130 sqm and EUR 350,000 reduced-rate limits and the 190 sqm and EUR 475,000 outer limits worked through.
- [How much VRAM do you need to run an LLM locally?](https://dubir.net/guides/how-much-vram-for-local-llm/): Weights plus KV cache plus overhead, with the arithmetic and real figures per model. Unified memory gives a model about 75% of the total; a dedicated GPU about 90%.
- [RTX 4090 vs 5090 vs Mac for local LLMs](https://dubir.net/guides/rtx-4090-vs-5090-vs-mac-for-local-llms/): The 5090 is about 1.78x the 4090, the exact ratio of their memory bandwidth. A 128GB Mac runs the 120B models neither Nvidia card can load, at roughly a third of the speed.
- [Ollama vs LM Studio vs vLLM](https://dubir.net/guides/ollama-vs-lm-studio-vs-vllm/): A desktop app, a model manager and a serving engine. They are close at one user and not comparable at twenty. vLLM has no Apple Silicon support.
- [When self-hosting an LLM is cheaper than an API](https://dubir.net/guides/when-self-hosting-an-llm-is-worth-it/): Breakeven against a frontier model is about 19M tokens a month; against a cheap hosted open-weight endpoint, about 420M, which means never in practice.

## FAQ

What does Dubir Group do? It builds software three ways: its own SaaS products, custom development for clients, and AI systems wired into how a business already works. Consulting sits alongside when a team needs a plan before the build.

Can Dubir run AI models on our own servers? Yes. When data cannot leave, Dubir deploys capable models inside the client's own infrastructure. The client keeps full control of the hardware and data, and nothing is sent to a third-party API.

Does Dubir only sell its own products, or build custom software too? Both. Hartia, Christine and Azurade AI are its own live products, but most work is custom: web and mobile apps, APIs, cloud platforms, and AI features built for one client's problem.

Where is Dubir Group based? Dubir Group Limited is registered in Cyprus (company number HE 394277) and based in Paphos. It works with clients wherever they are.

How do we start a project? Book a discovery / onboarding call at https://cal.com/delneg/dubir-15min, or email contact@dubir.net with what you are working on. A first call is enough to scope the work and say honestly whether Dubir is the right fit.
