Cataleo does not name a winner. Both statements come from the vendors themselves.

Full Comparison

Criterion DeepSeek Ollama
Starting price Free web and app; paid API The API is billed per token. Free for local models; Pro from $20 / month Local models cost nothing. Pro is $20 per month or $200 per year and includes $60 of cloud usage credits a month with three concurrent requests; Max is $100 per month with $300 of credits and ten concurrent requests; Team is $500 per month with $1,000 of shared credits and unlimited users; Enterprise is quoted. Extra credits can be bought on every paid plan.
Free trial Free web and mobile app Free plan with local models, starter cloud credits and one concurrent request
Commercial use Yes Not stated
Output Chat, reasoning, math and code Not stated
API Yes Yes, one REST API for local and cloud models, with Python and JavaScript libraries and a separate web search API
Hosting Not stated Runs locally on macOS, Windows and Linux; cloud models run on Ollama's servers in the United States, Europe and Singapore
Ecosystem Open-weight models, free web and mobile apps, and a very low-cost API; few office integrations Desktop app and command line for macOS, Windows and Linux, with integrations for VS Code Chat, Claude Code, OpenCode and n8n
Live web search and sources Yes, web search with cited sources Yes, through a separate web search API returning a title, URL and content snippet per result; it needs a free account and an API key, and is also reachable over MCP
Files and long documents Yes, document uploads (PDF, DOCX, TXT and code) and image reading Yes, the desktop app takes files by drag and drop so a model can reason over text or PDFs, and code files can be passed in for understanding; for large documents the context length is raised in the settings, which the vendor notes costs more memory
Images, voice and video Reads images; no image, audio or video generation Images for vision-capable models, passed as a file path, URL or base64 through the API and the libraries
Coding help Yes, strong at coding and math Coding models in the library, plus integrations with terminal coding agents such as Claude Code and OpenCode and with VS Code Chat
Model choice Yes, DeepSeek-V4 models (Flash and Pro) with a DeepThink thinking toggle Yes, and it is the point: any model from the library or an imported custom one, run locally or offloaded to the cloud through the same call
MCP-ready No stated Yes
Deployment Cloud (SaaS), Browser-based Cloud (SaaS), On-premise
Support Not stated Email helpdesk, Community forum
Onboarding Not stated Documentation and knowledge base
Company size Freelancers, Small and mid-sized, Enterprise Freelancers, Small and mid-sized, Enterprise
Integrations Not stated VS Code, JetBrains, Zed, Xcode, Claude Code, Claude Desktop, OpenCode, Cline, Roo Code, Codex CLI, Goose, n8n, marimo

The trade-offs

Strengths and Limitations

DeepSeek

Strengths

  • Free to use in the web and mobile app
  • Strong at reasoning, math and code
  • Open-weight models and very low API pricing

Limitations

  • Fewer office and ecosystem integrations than the big incumbents
  • No native image generation

Ollama

Strengths

  • Models run on your own machine, so on the free plan nothing is sent anywhere
  • The same API covers local and cloud models, so a model can be swapped without changing code
  • Chat, coding, vision, embedding and reasoning models in one library, plus imported custom models
  • Cloud use can be switched off entirely for a fully local setup

Limitations

  • Large models need capable local hardware; otherwise they run in the cloud on a paid plan
  • Cloud models and the web search API need an account and usage credits
  • Paid plans are metered in usage credits rather than seats, so the monthly cost varies with how hard it is used

Plans
