In a major expansion of its subscription lineup, OpenAI has officially launched a new $100/month ChatGPT Pro plan. This mid-range tier is designed to bridge the gap between the $20 Plus plan and the $200 top-tier Enterprise/Pro offerings, specifically targeting “vibe coders” and professional power users.
The centerpiece of this update is the broad availability of the GPT-5.4 Pro model, which represents a significant leap in reasoning, computer use, and long-form context handling.
1. The New $100 Subscription Tier
The new ChatGPT Pro ($100/month) tier focuses on agentic workflows and high-volume coding. In India, the plan is priced at ₹10,699/month.
- 5x Codex Limits: The plan offers five times the usage limits for Codex (OpenAI’s agentic coding harness) compared to the Plus plan.
- Model Access: Includes unlimited access to GPT-5.3 and high-capacity limits for GPT-5.4 Pro.
- “Cloud Tasks”: Pro users get a dedicated quota of “Cloud Tasks” (tasks run on OpenAI’s infrastructure) for long-running agentic sessions that would typically exceed local browser limits.
- Temporary Boost: OpenAI is offering a 2x usage boost for Pro subscribers through May 31, 2026, to encourage early adoption.
2. GPT-5.4 Pro: Key Capabilities
The GPT-5.4 Pro model is not just an incremental update; it is a high-compute version of the GPT-5.4 architecture that allocates significantly more “reasoning time” to each query.
- Native Computer Use: GPT-5.4 Pro is a leader in autonomous desktop navigation. It scored 75% on the OSWorld-Verified benchmark, outperforming the average human (72.4%) in using a computer via mouse and keyboard actions.
- 1.1M Token Context Window: For developers and researchers, the model can “read” over a million tokens at once, allowing it to absorb entire codebases or massive document sets in a single prompt.
- Hallucination Reduction: OpenAI reports a 33% reduction in factual errors compared to the GPT-5.2 generation.
- Reasoning Levels: The model supports adjustable “reasoning effort” (Medium, High, and xHigh) to balance speed against deep analytical depth.
3. Comparison of Individual Plans (April 2026)
| Feature | ChatGPT Plus | ChatGPT Pro (New) | ChatGPT Pro Max |
| Monthly Price | $20 | $100 | $200 |
| GPT-5.4 Pro Limits | 20–100 msgs/5hrs | 200–1,000 msgs/5hrs | 400–2,000 msgs/5hrs |
| Codex Capacity | Standard | 5x Standard | 10x Standard |
| Deep Research | Limited | Unlimited | Unlimited |
| Agent Mode | Standard | Advanced/Multi-Task | Priority Access |
4. API & Developer Costs
For developers using the model outside of the ChatGPT interface, GPT-5.4 Pro carries a premium price reflecting its high compute requirements.
- Input Cost: $30 per 1 million tokens.
- Output Cost: $180 per 1 million tokens.
- Long-Context Premium: For inputs exceeding 128k tokens, the price scales to $60/$270 respectively to account for memory overhead.
5. Why the Mid-Range Tier?
The launch of the $100 tier is seen as a strategic response to Anthropic’s rising dominance in the coding space.
- The “Vibe Coder” Market: OpenAI CEO Sam Altman noted the plan was launched “by very popular demand” from developers who felt the $20 Plus plan was too restrictive for real-world software engineering but didn’t need the $200/month enterprise-grade features.
- Codex Rebalancing: Alongside this launch, OpenAI “rebalanced” Plus limits, effectively shortening the duration of daily coding sessions for $20 users to encourage them to upgrade to the Pro tier.
