IONOS GPT vs. DeepSeek. How do they compare?

IONOS GPT and DeepSeek are two AI platforms that offer a wide range of cap­ab­il­it­ies. However, they differ in terms of structure, data sov­er­eignty and target audiences.

What are IONOS GPT and DeepSeek?

IONOS GPT provides four AI as­sist­ants that are easy to use and built to protect user data. The platform supports text, design, code and general tasks. DeepSeek, in contrast, develops large language models that spe­cial­ise in handling long and complex inputs, and is par­tic­u­larly well suited for pro­gram­ming tasks and lengthy documents. DeepSeek is developed by a company based in China.

What are the main features of IONOS GPT?

IONOS GPT is an AI platform built around European re­quire­ments, with data pro­tec­tion, trans­par­ency and ease of use, along with dedicated features for specific tasks, at its core. It’s this com­bin­a­tion that sets IONOS GPT apart from many in­ter­na­tion­al com­pet­it­ors.

Four spe­cial­ised AI as­sist­ants

IONOS GPT is divided into four AI as­sist­ants. Each assistant takes on a specific task: text gen­er­a­tion, image ideas, pro­gram­ming as­sist­ance or general questions. This clear sep­ar­a­tion reduces com­plex­ity. Users can quickly find the right tool without lengthy prompting or ex­per­i­ment­ing.

Data pro­tec­tion on a European level

IONOS GPT’s com­pli­ance with GDPR is one of the platform’s key features. It stores all data in ISO-certified data centres in the EU, which ensures users retain full control. The platform does not use data for model training either, making it par­tic­u­larly suitable for data-sensitive sectors like ad­min­is­tra­tion, education, health­care or law.

Open tech­no­logy and trans­par­ency

IONOS GPT uses the open-source Llama model, which is fully doc­u­mented and available through the IONOS Model Hub. Users can see where the tech­no­logy comes from and how it works, unlike many closed platforms developed by companies that do not disclose how their tech­no­logy works.

Easy for beginners and teams

The platform runs directly in the browser, with no in­stall­a­tion required. The interface is clear, available in several languages and designed so that even users without technical knowledge can use it almost straight away. This makes it es­pe­cially practical for small busi­nesses or in­di­vidu­al de­part­ments.

In­teg­ra­tion of own data and documents

IONOS GPT supports uploading documents in PDF or DOCX format, allowing the AI to process this content and answer questions in context. This feature is par­tic­u­larly useful for building internal knowledge bases, managing customer in­form­a­tion or preparing training materials. All files are processed within the EU and never leave it. Your content remains under your control at all times.

Reasoning Mode

IONOS GPT includes a Reasoning Mode for trickier tasks. Rather than jumping straight to an answer, the AI works through complex queries step by step, checking its progress along the way and cor­rect­ing any errors before giving you a final response. This makes it well suited to financial planning, contract analysis, technical ar­chi­tec­ture design and complex logic problems.

Web search

The built-in web search function lets IONOS GPT pull in up-to-date in­form­a­tion from across the web. So rather than solely relying on its trained knowledge, it can draw on sources and data that are refreshed daily.

Dif­fer­ences from DeepSeek

Both platforms rely on open AI models, but their focus is different. DeepSeek provides larger context windows and is aimed primarily at de­velopers and re­search­ers. IONOS GPT, by contrast, focuses on everyday business tasks where security and com­pli­ance are essential. Its interface is easier to navigate, and it performs sig­ni­fic­antly better when it comes to data pro­tec­tion.

What are the key features of DeepSeek?

DeepSeek AI offers large language models tailored to technical and research en­vir­on­ments. The platform provides flexible in­ter­faces, open model weights and strong per­form­ance with large-scale inputs.

Models with mix of experts design

The DeepSeek R1 and V3 models use a mix of experts ar­chi­tec­ture, where only specific parts of the model are activated for each request. This design saves resources without no­tice­ably reducing quality. As a result, the models perform well in areas such as math­em­at­ics, pro­gram­ming and complex text analysis.

Large context windows for document pro­cessing

DeepSeek can handle inputs of up to 128,000 tokens, making it suitable for long documents and technical data. Users can upload PDFs or text files and have them analysed in chat. Responses are based directly on the provided material and often include useful summaries or insights.

Pro­gram­ming In­ter­faces

DeepSeek is available via an API, allowing de­velopers to integrate the models into their own ap­plic­a­tions. Pricing is usage-based and depends on the number of input and output tokens.

Open weights with MIT licence

The model weights are published under the MIT licence, which gives de­velopers flex­ib­il­ity to reuse them in their own projects. However, other elements, such as the training data and in­fra­struc­ture, are not disclosed.

Comparing DeepSeek with IONOS GPT

DeepSeek is a versatile tool for technical tasks, pro­gram­ming and research, backed by powerful models and an open, flexible setup. For data-sensitive use cases or or­gan­isa­tions without deep technical expertise, IONOS GPT offers more control, clarity and data pro­tec­tion. DeepSeek tends to suit ex­per­i­enced users with technical know-how, while IONOS GPT makes it easy to get started without com­prom­ising on security or func­tion­al­ity.

IONOS GPT vs. DeepSeek – which uses are they best for?

The choice between IONOS GPT and DeepSeek depends on the specific use case. Both platforms can support in­di­vidu­als and or­gan­isa­tions, but they differ in com­plex­ity, ease of use and data pro­tec­tion. The following scenarios highlight where each solution works best.

IONOS GPT

• Text creation in or­gan­isa­tions: Editorial teams, marketing de­part­ments and internal com­mu­nic­a­tions teams can use IONOS GPT to draft press releases, news­let­ters or legally sensitive content without data leaving the company. Or­gan­isa­tions that must meet strict data pro­tec­tion or reg­u­lat­ory re­quire­ments benefit from GDPR-compliant hosting in European data centres.
• De­vel­op­ing secure software projects: Software de­velopers can use IONOS GPT to generate code modules, examples or ex­plan­a­tions. In projects where data security is crucial – such as public sector IT services or medical tech­no­logy – the platform provides a con­trolled and secure en­vir­on­ment.
• Knowledge man­age­ment in companies: Busi­nesses can build their own knowledge bases by uploading PDFs, guidelines or internal doc­u­ment­a­tion. The AI can then deliver con­tex­tu­al responses, turning company in­form­a­tion into a struc­tured, ac­cess­ible resource.
• Regulated in­dus­tries: IONOS GPT is suitable for public au­thor­it­ies, schools, uni­ver­sit­ies and health­care or­gan­isa­tions that handle con­fid­en­tial data. By complying with European security standards and pro­cessing in­form­a­tion locally, the platform supports safe AI use even where data pro­tec­tion and trans­par­ency are top pri­or­it­ies – for citizen enquiries, teaching materials or medical reports for example.
• Small busi­nesses and agencies: Freel­an­cers, agencies and SMEs can use IONOS GPT for recurring tasks. The intuitive interface reduces training time, while the modular design makes it easy to apply the AI to different workflows, boosting ef­fi­ciency in day-to-day work.

DeepSeek

• Research and large-scale data analysis: DeepSeek is well suited to sci­entif­ic research, technical studies and lengthy reports, thanks to models that can handle very long text inputs.
• Software de­vel­op­ment: De­velopers can integrate DeepSeek into their systems via the API. The platform can generate code, suggest im­prove­ments to existing scripts and analyse pro­gram­ming logic.
• Math­em­at­ic­al and logical problem-solving: DeepSeek is reliable and precise when it comes to maths and logic tasks, from algebra to stat­ist­ics and op­tim­isa­tion.
• Custom AI in­teg­ra­tion: With its open-weight models, DeepSeek can be embedded into existing technical ar­chi­tec­tures. Companies building their own AI ap­plic­a­tions or spe­cial­ised workflows benefit from the ability to adapt the models at code level, making DeepSeek a strong fit for embedded projects or cloud-based services with a technical focus.
