Pros and cons

ChatGPT

Chatbots · freemium

Pros

  • Free tier runs a current-generation model (GPT-5.6 Luna) with the Think button, not a downgraded legacy one
  • Reasoning-effort slider on Plus and Pro puts per-message thinking depth under your control instead of a hidden router's
  • Codex mobile lets you start, steer and approve coding agent runs from your phone — and it is on every plan, including Free
  • Broadest single-app surface: full-duplex GPT-Live voice, native image generation, inline Runway video, Deep Research, agent mode and file analysis
  • Lockdown Mode is a real architectural cutoff against prompt-injection exfiltration, not a policy promise

Cons

  • ×OpenAI's headline figures — 68% fewer factual errors, Sol's Terminal-Bench result — are self-measured on evaluation sets the company has not published
  • ×Not the leader on any single axis anymore: Claude is better for long-form writing and agentic coding, Gemini 3.5 Pro for ecosystem reach and context length
  • ×The most interesting features land on the $200/mo Pro tier first — the finance mode shipped Pro-only and stayed there
  • ×Video generation leans on a Runway partnership rather than a deeply integrated Sora, and Go-tier price and availability differ by country

Pros

  • Octave builds a usable voice from a written character description, so no source audio or cloning consent is needed
  • Per-line acting instructions give directable delivery instead of global voice-setting sliders
  • EVI works as a voice layer over an external LLM, so it drops into an existing agent stack without a model switch
  • Expression Measurement is a genuine analysis product, covering voice, face and language, not just a sentiment score
  • Peer-reviewed affective-science grounding rather than marketing claims about emotional AI

Cons

  • ×Realtime conversational voice is commodity infrastructure in 2026 (OpenAI Realtime, Gemini Live, ElevenLabs Agents), which narrows Hume's edge to the emotion layer specifically
  • ×The EU AI Act bans emotion recognition in workplace and education settings, closing off a large slice of enterprise use
  • ×Emotion inference from voice is scientifically contested and accuracy varies across accents and cultural context
  • ×Developer-only platform with a smaller ecosystem, integration count and community than ElevenLabs or the major model vendors
