Free trial Free tier, without memory and with limited images Free plan with local models, starter cloud credits and one concurrent request
Commercial use Yes Not stated
Output All-in-one chat, files, images, voice and agent tasks 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 Large ecosystem with many 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 citations 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, file uploads 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 Yes, image generation and voice Images for vision-capable models, passed as a file path, URL or base64 through the API and the libraries
Coding help Yes, also Codex for software engineering 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, model picker for faster or deeper responses 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

The trade-offs

Strengths and Limitations

ChatGPT

Strengths

  • Most versatile all-rounder
  • Largest ecosystem and integrations
  • Image, voice and agent features built in

Limitations

  • Not best-in-class at any single niche
  • Free tier limited, no memory and limited images

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
