About ChatGPT

ChatGPT is OpenAI's flagship conversational AI, the product that ignited the mainstream AI revolution. Its model has turned over four times in 2026 — GPT-5.5 in April, the GPT-5.6 range over the summer, GPT-6 Astra from September 3, 2026, which OpenAI is rolling out to Plus, Pro, Business and Enterprise in stages with cybersecurity tasks restricted, and GPT-6 Sol and GPT-6 Luna from September 22 at half the GPT-5.6 rates, in ChatGPT Work and Codex for paid plans and, for Luna, the desktop app on Free and Go. Around the model sit the features that make it one tool for everything: DALL-E 3 image generation, Code Interpreter for data analysis, web browsing with citations, file uploads, Voice Mode and custom GPTs. Per OpenAI's plan page (September 8, 2026, which shows model allocation but localises prices): Free gives unlimited text chats with GPT-5.6 Luna; Plus adds advanced reasoning with GPT-6 Astra and GPT-5.6, expanded uploads, image creation, deep research, projects and custom GPTs; Pro, now sold in 5x and 20x usage tiers, adds Pro reasoning powered by GPT-6 Astra, maximum Codex tasks and unlimited, faster image creation. Our ChatGPT Plus & Pro review priced Plus at $20 and Pro at $200 a month and covers the September 2026 lineup. Best for: general-purpose AI assistance, image creation, data analysis, and the broadest plugin ecosystem.

GPT-6 Sol Review: Half the Cost per Task, Barely Smarter

4.2

GPT-6 Sol halves GPT-5.6 Sol’s per-token price, and on the independent Artificial Analysis index it nearly halves the bill per task too: $1.06 against $1.99, for a score of 48 against 47. No model scoring 48 or more finishes a task for less. It is barely smarter than the model it replaces, and Claude Opus 5.5 at high scores 54 for $1.82. In our own build tests Sol was fast, and each of its three builds had a fault you could see.

Pros:
  • +Cheapest per task of any model scoring 48 or more on the Artificial Analysis index at $1.06
  • +One index point above GPT-5.6 Sol for 53% of its cost per task
  • +$2/$10 per million tokens — rates OpenAI says are permanent
Cons:
  • -One index point above GPT-5.6 Sol — the step is in price rather than capability
  • -Claude Opus 5.5 at high scores 54 for $1.82 a task — six points more
  • -OpenAI’s head-to-heads pit it against last-generation Claude and GPT-6 Astra at low effort

GPT-6 Astra Review: Frontier Intelligence, Half the Cost

4.5

Astra launched to a brutal independent read: intelligence level with the model it replaces, at 2.5x the price. That framing measured cost per token. Measured per finished task — the number you actually pay — Astra completes the Artificial Analysis Intelligence Index for $4,064 where Claude Fable 5.1 needs $10,816, and scores two points behind it. Our own testing found the same speed advantage, and one repeated weakness no benchmark catches.

Pros:
  • +Finishes the Artificial Analysis Intelligence Index for 37% of what Claude Fable 5.1 spends
  • +Uses 49M output tokens where Fable 5.1 needs 160M and Opus 5 needs 120M
  • +Third overall on Intelligence Index v4.2 at 55 — a point above Claude Opus 5
Cons:
  • -Not the smartest available — Claude Fable 5.1 scores 57 to Astra’s 55
  • -Costs more per finished task than the GPT-5.6 Sol it replaces
  • -322 seconds to first token at max effort — slowest of the frontier group

ChatGPT Plus & Pro Review 2026: Is It Worth $20?

4.7

ChatGPT Plus is still the best $20 in AI and Pro is still a $200 question — now with GPT-6 Astra, Sol and Luna rolling out to both tiers. What changed since our GPT-5.5 hands-on, where Claude still wins, and who actually needs Pro.

Pros:
  • +Frontier models reach Plus
  • +not just Pro
  • +Truly agentic — plans and executes multi-step workflows
Cons:
  • -Pro at $200/mo is steep
  • -Astra rollout is staged and cyber tasks are restricted
  • -Computer Use mode still rough on edge cases
