ChatGPT Pricing Timeline: From Free Launch to 6 Plans
In just over three years, ChatGPT has evolved from a single free product to a six-tier platform with consumer subscriptions, team plans, enterprise deals, and a comprehensive API. Meanwhile, API costs have plummeted by over 90%. This timeline traces every significant pricing event from the November 2022 launch through today.

Complete Timeline
ChatGPT launches
OpenAI releases ChatGPT as a free research preview using GPT-3.5. It reaches 1 million users in 5 days and 100 million in 2 months, becoming the fastest-growing consumer application in history. No paid option exists at launch.
ChatGPT Plus launches at $20/mo
The first paid tier arrives at $20 per month, offering priority access during peak times, faster response speeds, and first access to new features. At launch, it provides GPT-4 access while free users remain on GPT-3.5. This price has never changed.
GPT-4 API launches
GPT-4 API launches at $30 per million input tokens and $60 per million output tokens. These prices seem astronomical compared to current rates but represented the state of the art at the time. Only select developers get initial access.
GPT-4 API price cut (25%)
OpenAI reduces GPT-4 API pricing by approximately 25% as inference costs decrease. This begins a pattern of consistent API price reductions that continues through 2026.
GPT-4 Turbo launches
GPT-4 Turbo launches with a 128K context window at $10 per million input tokens and $30 per million output, roughly 3x cheaper than the original GPT-4 API. Custom GPTs launch for Plus subscribers.
Team plan launches at $25/user/mo
OpenAI launches ChatGPT Team for businesses at $25 per user per month on annual billing, $30 on monthly. Minimum 2 users. Includes admin console, higher message limits, and data privacy protections.
GPT-4o launches (50% cheaper)
GPT-4o is released at $5 per million input tokens and $15 per million output - 50% cheaper than GPT-4 Turbo with improved performance. GPT-4o-mini follows at $0.15 per million input, making AI accessible at unprecedented low costs.
O1 reasoning models launch
OpenAI launches the O1 model family (O1, O1-mini, O1-preview), introducing a new category of reasoning models that think before responding. O1 is priced at $15 per million input and $60 per million output.
ChatGPT Pro launches at $200/mo
The premium Pro tier arrives at $200 per month, offering unlimited access to the most capable models and 250 Deep Research runs per month. It targets researchers, analysts, and power users who need maximum capability.
O3-mini releases
O3-mini launches as a more affordable reasoning model, bringing reasoning capabilities to a wider audience of developers at significantly lower costs than the full O3 model.
Student promotion ends
The limited-time promotion offering free ChatGPT Plus to US and Canadian college students expires. OpenAI does not announce a replacement program, directing students to the free tier or upcoming Go plan.
Team renamed to Business
ChatGPT Team is rebranded as ChatGPT Business with the same $25 per user per month pricing. The rebrand comes with 60+ app integrations (Slack, Google Drive, SharePoint, GitHub) and enhanced admin controls.
ChatGPT Go launches at $8/mo
The new budget tier launches globally at $8 per month, offering unlimited GPT-5.2 Instant access, 10x file upload limits, and extended memory. Go fills the gap between Free and Plus, targeting budget-conscious users and international markets.
Ads introduced on Free and Go
OpenAI introduces contextual advertisements on the Free and Go tiers in the United States. This represents a significant monetisation shift, creating a new revenue stream beyond subscriptions and API fees. Plus and Pro remain ad-free.
GPT-5.4 launches
GPT-5.4, the latest iteration in the GPT-5 model family, is released. The GPT-5.4 Pro variant is exclusive to Pro subscribers. API pricing for GPT-5 remains at $1.25 per million input and $10 per million output, representing a major cost reduction from earlier model generations.
What the Trends Tell Us
Consumer Prices: Remarkably Stable
ChatGPT Plus has been $20/month for over three years without a single price increase. Instead of raising prices, OpenAI has added value by expanding the feature set (Deep Research, image gen, Agent Mode, Sora). The Business plan has similarly stayed at $25/user/month since the Team launch. This stability suggests OpenAI views these price points as strategically correct for market positioning, especially given competition from Claude at $20 and Gemini at $19.99.
API Prices: Rapid Deflation
API pricing has followed a steep deflationary curve. GPT-4 output tokens cost $60/1M at launch in March 2023. The equivalent GPT-5-mini output costs $2/1M in 2026, a 97% reduction. Even comparing flagship-to-flagship, GPT-5 at $10/1M output is an 83% reduction from GPT-4. This trend benefits developers enormously and is driven by hardware efficiency gains, model distillation, and competitive pressure from Google and Anthropic.
Tier Expansion: More Options
OpenAI has consistently expanded its product line rather than adjusting prices. From a single free product in 2022 to six tiers in 2026 (Free, Go, Plus, Pro, Business, Enterprise), each launch has addressed a specific market gap. Go addresses budget users, Pro addresses power users, and Business addresses team governance needs. This segmentation strategy is likely to continue with potential additions like student-specific tiers or usage-based plans.
Predictions for 2026-2027
Based on current trends, API prices will likely continue falling as GPT-5 derivatives become more efficient. Consumer subscription prices are expected to remain stable at current levels. OpenAI may introduce a permanent student discount or seasonal promotions. The ad-supported model on Free and Go could expand to more markets. A new tier between Plus and Pro (perhaps at $50-100/month) is plausible given the large gap between them. Enterprise pricing may face downward pressure from Claude and Gemini enterprise offerings.
