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

LM Studio

Strengths

  • Downloading, running and chatting with open models happens in one desktop app, with no terminal needed
  • Free for local use, including at work: no commercial licence is required
  • A local OpenAI-compatible server makes existing code work against a local model unchanged
  • Runs on Apple Silicon, Windows and Linux, with MLX used on Apple Silicon
  • Acts as an MCP client, so MCP servers can be used with local models

Limitations

  • Answer quality is bounded by the models the local hardware can run
  • The hosted open models and fuller web search need a paid plan
  • Team subscription plans are not available yet, only shared billing through an organisation
  • Cloud usage beyond a plan's allowance is billed as credits, so the monthly cost varies with use
