Pros and cons

DeepSeek

Pros

  • Web chat and mobile apps are free
  • API output costs from $0.60 per 1M tokens (Flash, off-peak), well below most frontier providers
  • Open weights for V4 and earlier models on Hugging Face
  • 1M-token context and 384K max output on both API models
  • API works with both OpenAI and Anthropic SDKs and several coding agents

Cons

  • Peak-hour API rates are double the off-peak rates on weekday mornings UTC
  • deepseek-v4-pro does not support vision input
  • No image generation
  • Data is processed by a company based in China, which some organizations cannot accept

Kimi

Pros

  • International USD plans start at $19/month and include Kimi Code and Agent Swarm.
  • Broad agent toolset: deep research, slides, documents, spreadsheets, website building and scheduled tasks.
  • A separate pay-per-token API with a 1M-token context window on K3.
  • Rated 4.7 out of 5 from 5.3K ratings on the US App Store.
  • Earlier K2-family models were reported to have downloadable weights, which suits self-hosting teams.

Cons

  • Free-tier limits are not clearly published on the help pages.
  • Plan structure is changing: legacy plan names (Moderato, Allegretto, Allegro, Vivace) coexist with Plus, Pro, Max and Ultra, which can confuse buyers.
  • Credits do not roll over, and one shared pool covers chat, agents and Kimi Code.
  • The site interface and several help pages default to Chinese; I found no confirmed Android or Windows client.
