What ChatGPT Go is and why it was created

ChatGPT Go is OpenAI's answer to the demand for a more affordable subscription for everyday users. OpenAI decided to fill the gap between the free tier and ChatGPT Plus ($20/month, roughly 480 CZK in Czechia) with a plan that costs about a fifth of the Plus price — yet still offers most of the key features.

According to OpenAI's official pricing page (openai.com/pricing), Go includes everything the Free tier has, plus it adds extended access to the GPT-5.5 Instant model, more messages, higher file upload limits, faster image generation, and longer context memory. A new addition is the ability to create and share custom GPT assistants — a feature previously exclusive to Plus and higher tiers.

An interesting detail is that the Go plan may include ads. OpenAI confirms this on its website with the note "This plan may include ads." This marks the first time an ad-supported model appears directly in ChatGPT — until now, the company earned revenue solely from subscriptions and its API.

How much ChatGPT Go costs and where it's available

The first rollout targeted 16 Asian countries, including Vietnam, Indonesia, the Philippines, Thailand, and Malaysia, where ChatGPT Go launched in October 2025. In Vietnam, it came to 132,000 VND per month including VAT (approximately 120 CZK). For comparison: ChatGPT Plus costs 522,500 VND there (about 480 CZK) and ChatGPT Pro goes for 5,225,000 VND (about 4,800 CZK).

At the time of writing (May 2026), ChatGPT Go appears on OpenAI's official pricing page alongside Free, Plus, Pro, and Business, suggesting global availability — or at the very least, an imminent broader rollout. However, OpenAI has yet to officially confirm a launch for European users, including Czechia. The Go plan is listed on openai.com/pricing, but without a specific price in euros or Czech crowns.

What ChatGPT Go offers compared to the Free tier

The differences between the plans are clearly visible on OpenAI's comparison table:

• Model: Go runs on GPT-5.5 Instant — the same model as the Free tier, but with less restrictive limits. The Plus tier adds GPT-5.5 Thinking (advanced reasoning) and Pro further adds GPT-5.5 Pro.
• Context window: The Free tier offers 27K tokens, while Go doubles that to 54K tokens. That means roughly 40 pages of text can fit into a conversation instead of 12.
• Deep Research: Limited access to deep research, similar to the Free tier. Full access remains with Plus and Pro.
• Images: More generation capacity and faster response compared to Free. However, advanced generation with "thinking" remains exclusive to Plus.
• Codex: Limited access to the AI coding assistant — enough for basic tasks, but developers will want Plus.
• Custom GPTs: For the first time in a low-end plan — you can create and share your own assistants.

Competition: Google AI Plus and others

In Asian countries, ChatGPT Go directly competes with Google AI Plus, which costs 122,000 VND (about 112 CZK) in Vietnam and offers Gemini 2.5 Pro, Deep Research, video generation via Veo 3 Fast, NotebookLM, and 200 GB of shared storage across Google services. It's an interesting comparison: Google gives you more for similar money — including video and cloud storage.

In Europe, the situation is different. Google One AI Premium (the European equivalent of Google AI Plus) costs €21.99 per month (about 550 CZK) and includes Gemini 2.5 Pro, 2 TB of storage, and integration with Google Workspace. ChatGPT Plus comes in at $20 (about 480 CZK). Between these two tiers and the free version, there remains a significant pricing gap that ChatGPT Go could fill — if OpenAI were to set a European price around €5–6 (roughly 120–150 CZK).

What this means for Czech users

For Czech users, the key question is: will we get ChatGPT Go at a similarly low price? Experience with other OpenAI plans isn't exactly encouraging — ChatGPT Plus costs $20 in the US, but in Czechia you pay the equivalent in crowns (excluding VAT), which works out to more than 480 CZK. If Go were to arrive at €5–6 (about 130–160 CZK with VAT), it could be an attractive option for students, freelancers, and casual users who don't want to pay the full Plus price.

It's also worth noting that ChatGPT supports Czech at a very solid level — the GPT-5.5 models handle Czech grammar, context, and specialized terminology without major issues. This holds true across all plans, including the Free tier.

Why OpenAI needs a cheaper plan

ChatGPT faces increasingly strong competition. Google Gemini offers a solid free tier and a richer ecosystem, Anthropic Claude is winning over enterprise customers, DeepSeek from China is driving prices down, and Meta AI is available for free across platforms. In Asia, moreover, according to a 2025 Decision Lab survey, 81% of AI users use ChatGPT, followed by Gemini (51%) and Meta AI (36%) — competition is fierce even where ChatGPT dominates.

A lower-priced, ad-supported plan gives OpenAI a new monetization model that can reach millions of users in developing markets. For a company that, according to available reports, is still operating at a loss, this makes economic sense.

Whether ChatGPT Go will appear in Czechia is not yet certain. But the fact that it's listed on OpenAI's main pricing page alongside global plans suggests it's more a question of "when" rather than "if." We recommend keeping an eye on developments directly on the official OpenAI pricing page.
