Official still from cdn.openai.com — how ChatGPT presents the interface in share previews, not a stock substitute.
Independent review
ChatGPT — chat, code, images, and voice in one workspace
I walked through chatgpt.com and the pricing page: below is how Free, Go, Plus, and Pro differ, what GPT-5.6 Luna, Sol, and Sol Pro are for, and when it makes sense to open the product versus browsing the model catalog here.
Overview
What is ChatGPT
ChatGPT is OpenAI's product for everyday work with text, code, images, and voice. The chatgpt.com homepage invites you to start a conversation; the pricing page lists Free, Go, Plus, and Pro with different limits on models, uploads, image creation, voice, deep research, and Codex.
For me it is a workspace, not a magic oracle: draft an email, unpack a PDF, ask Codex to tighten an API helper, generate a slide illustration, or read a draft aloud. Current limits and prices live on the official ChatGPT website — I capture how the product matrix is organized, not copy the price list word for word.
Free advertises unlimited text chats with GPT-5.6 Luna, but caps uploads, images, voice, deep research, memory, Codex, and ChatGPT Work. Go adds more tool messages and uploads; Plus unlocks GPT-5.6 Sol, expanded limits, and projects; Pro multiplies usage and adds GPT-5.6 Sol Pro. Business and Enterprise on pricing target teams with admin tools and SSO.

Showcase
What ChatGPT can do today
Only domains confirmed on pricing: text, code, images, and voice. Stills come from OpenAI's CDN; snippets are editorial examples of the work format.
Second frame from the same official set — useful to see brand tone before you enter the chat.
const res = await fetch("/api/invoices/42");
if (!res.ok) throw new Error(`Invoice HTTP ${res.status}`);
const data = (await res.json()) as Partial<Invoice>;
return { id: data.id, total: data.total, currency: data.currency ?? "USD" };Typical Codex ask: remove loose typing in an API response when the repo is already connected.
Brief. Client email moving a deadline to Thursday, 10:00. Calm tone. Attach a 25-minute agenda and a link to the updated spreadsheet.
Task framing before wording — how I start a working thread instead of "write something."
Voice. Read a post draft aloud, shorten the intro, and add one concrete example from the case study without marketing clichés.
Plus and Pro widen voice limits; Free includes the mode but with caps visible in the plan compare table.

Why move from Free to a paid plan
GPT-5.6 Sol
Plus turns on advanced reasoning — noticeable on long documents and multi-step tasks.
Codex
Expanded Codex on Plus/Pro — less friction when refactoring across files.
Images
Plus promises more complex image creation; Pro adds speed and higher fair-use headroom.
Memory and projects
Longer context, projects, and scheduled tasks — easier to run parallel workstreams.
Audience
Who ChatGPT fits
- Writers and editors — drafts, tone edits, long-form structure; Go/Plus raise message ceilings.
- Developers — Codex, repo-aware edits, data analysis; Pro maximizes Codex tasks.
- Researchers — deep research and uploads; Free is trimmed, Plus/Pro widen the window.
- Teams — Business/Enterprise with SSO, admin console, and unified billing when you need a shared workspace.
FAQ
Common questions
Yes — Free includes unlimited text chats with GPT-5.6 Luna, but limits uploads, images, voice, research, memory, and Codex. Go, Plus, and Pro expand those caps; details are on pricing.
Luna is the Free default for everyday chats. Sol is the advanced reasoning tier on Plus and above — better for multi-step work and heavier documents. Sol Pro on Pro adds even higher usage headroom.
I do not see a standalone text-to-video product inside chatgpt.com on the pricing compare table. Voice, vision, and images are listed; video generation as a ChatGPT feature is not called out there.
Codex is the coding block: edits, repo context, and higher limits on Plus/Pro. Free access is limited — pricing marks it as a separate row with different checkmarks per plan.
Product homepage — chatgpt.com. Plans — chatgpt.com/pricing. This review does not replace signing in to OpenAI.
Pricing lists Business and Enterprise with SAML SSO, admin console, unified billing, and granular GPT controls. Solo work often stops at Plus or Pro; companies should read corporate plans on the official site.

Plus covers long drafts and spreadsheet edits — memory feels noticeably longer than on Free.

Codex with the repo connected saves typing in the API layer, though I still review merges myself.
Alina S.
4 out of 5
Slides come together faster with images, but Free limits show up when I iterate many variants in a row.
Paul D.
5 out of 5
Voice is handy for walking through a post draft; on Plus the response feels steadier than I expected.
Elena R.
5 out of 5
Deep research helped me sketch a market overview in an evening — I still verify numbers, but the outline saves hours.
