OpenAI Makes Free ChatGPT Unlimited

9AUG
1B USERS A WEEKFREE CHATTHINKING

The cheapest AI just got cheaper. OpenAI made text chat unlimited for ChatGPT's free tier, with a Think button for harder questions. Paid tiers now sell reasoning, not access.

ChatGPT serves 1 billion people a week. Free and Go users now default to GPT-5.6 Luna with no cap on text chats. Limits stay on file uploads, images, and voice.

Paid users get an updated GPT-5.6 Sol and a slider for how hard it thinks. OpenAI says factual errors dropped 68% against GPT-5.5 Instant. One model now handles quick and deep.

The paywall moved. It no longer sits between you and a chatbot. It sits between you and how much the chatbot thinks.

full brief & sources

⚡ Why this matters

  • Free unlimited chat resets what a paid AI subscription has to be worth.
  • Every competitor selling basic chat access now has a pricing problem.
  • The marginal cost of a text answer is close enough to zero to give away.

🔍 What happened

  • OpenAI updated the default ChatGPT model experience across all tiers.
  • Free and Go users move to GPT-5.6 Luna as default, with unlimited text chats rolling out the week after.
  • A new Think button gives free users extended reasoning on harder questions.
  • Plus and Pro get an updated GPT-5.6 Sol plus a slider controlling reasoning depth.
  • In internal evals on financial, medical and legal prompts, responses with at least one factual error fell 68% versus GPT-5.5 Instant.
  • Caps remain on file uploads, image generation, and voice.

💬 Smart takes

  • OpenAI: "This is a concrete step toward more abundant intelligence."
  • Hiroki Miyano, AI newsletter writer: if free-tier volume jumps, the experiences competitors only offer behind a paywall lose relative value.
  • Skeptic: unlimited text costs OpenAI little because text is the cheapest thing it serves. The expensive parts, video and voice and file work, are still capped.

🧭 Where this goes

  1. LikelyGoogle and Anthropic loosen their free-tier limits within 90 days.
  2. Likelyconsumer AI pricing shifts from access tiers to reasoning-depth tiers.
  3. Possiblefree-tier volume pushes OpenAI to route more traffic to its cheapest models by default.
  4. Wild Carda major competitor drops its consumer paid tier entirely and monetizes only through API and enterprise.

🥄 The Spoon Take

Access stopped being the product. Every consumer AI now has to answer a harder question: what exactly are you charging for? OpenAI's answer is thinking time. Will be interesting to see whether anyone can sell something else.

🤔 Pushback

Unlimited text is cheap to give away. The costly features are still capped, so the paywall moved rather than fell.
