ChatGPT — AI Tool Review, Features & Pricing

About ChatGPT

OpenAI's flagship conversational AI. As of September 2026 the top model is GPT-6 Astra (released September 3, 2026), built for the hardest end-to-end work across reasoning, coding, computer use, research and document creation, with a 1.05M-token context. GPT-6 Sol and GPT-6 Luna followed on September 22, 2026 — Sol for complex coding and agentic workflows, Luna for focused high-volume tasks — but inside ChatGPT they run in Work and Codex, not in the regular Chat. GPT-6.1 Sol followed on September 29, 2026 with near-Astra performance at a lower cost; it also runs in Work and Codex rather than Chat, on Plus and higher plans. The GPT-5.6 family stays selectable during that rollout — Sol for complex professional work, Terra as the balanced everyday model, Luna as the fast low-cost option. Natively omnimodal with autonomous computer use and agentic task execution. The previous-generation GPT-5.5 retired from Codex for ChatGPT sign-ins on October 14, 2026, and stays on the API; it scored 82.7% on Terminal-Bench 2.0 and 78.7% on OSWorld-Verified when it led the line in April 2026. Image generation runs on GPT Image 2.5 Sunburst and Flare, released September 8, 2026. Coding work runs through Codex, which is a surface of ChatGPT rather than a separate product — it shares this model lineup and plan ladder and runs inside the ChatGPT desktop and web apps as well as its own CLI and IDE extension.

It belongs to the text category (subcategory: general-writing) within the AI Workflows tool directory.

ChatGPT offers a freemium model with a free tier and paid upgrades.

Editorial Review: ChatGPT scores 9.0/10

Our editors scored ChatGPT 9.0 out of 10 overall (4.5 out of 5 stars), averaged across 5 independently rated dimensions.

Pros of ChatGPT

• Largest plugin and connector ecosystem of any AI assistant in 2026
• Best general-purpose model for non-technical users — minimal prompt fluency required
• Free tier is genuinely useful — real frontier-model access with daily limits, not a crippled demo

Cons of ChatGPT

• Hallucinates on niche or post-cutoff topics without web search enabled
• Memory feature still less reliable than Claude's in 2026
• Voice mode and advanced features are gated behind Plus / Pro tiers

When to use ChatGPT

• First-stop tool for brainstorming, drafting, and quick research
• Daily team assistant when you need broad capability over depth
• Multimodal tasks involving image input, charts, and code interpretation

The editor's take on ChatGPT

ChatGPT in 2026 is the default general-purpose AI for the same reason Google was for search: ubiquity. GPT-6 Astra, OpenAI's top model since September 2026, handles the hardest end-to-end work, while GPT-5.6 Terra covers 90% of everyday knowledge work — drafting, brainstorming, code review, vision tasks — without you having to think about model choice. It loses to Claude on long-context reasoning and to Perplexity on real-time research, but as a daily driver it remains hard to beat.

Pricing & Plans

• Pricing model: Freemium
• Plan details: Plan ladder as of October 2026: Free at $0, Go at $8/month, Plus at $20/month, Pro from $100/month (with $200 and $500 per month plans above it), Business at $20 per user per month, plus unpriced Enterprise and Edu plans. Paid tiers carry GPT-6 Astra and the GPT-5.6 family including Sol, Terra and Luna, with Luna raising usage limits on lighter, high-volume work. In Work and Codex, Plus and higher plans also get GPT-6.1 Sol, GPT-6 Sol and GPT-6 Luna, while Free and Go get GPT-6 Luna in the desktop app as it rolls out. OpenAI does not publish which model the free tier's Chat serves, so we do not state one.
