OpenAI recently transitioned its core ChatGPT subscription tiers—Go, Plus, and Pro—from fixed monthly fees to negotiated pricing. Before July 27, 2026, these plans were listed at $8, $20, and $100 per month. The ChatGPT Free tier remains at $0, though all professional and research-oriented plans now require direct sales engagement.
For API integration, the pricing structure remains token-based and highly granular. Rates are determined by the specific model version and context length, with gpt-5.4-nano representing the entry-level cost at $0.20 per 1M input tokens, while high-performance models like gpt-5.5-pro reach $180.00 per 1M output tokens.

How does the shift to "Contact Sales" affect procurement?
The removal of transparent pricing for the Go, Plus, and Pro plans suggests a move toward volume-based enterprise discounting or customized service-level agreements. For Finance and Procurement teams, this change necessitates usage-based forecasting to negotiate effective per-seat or per-org rates, as the previous $8 to $100 benchmarks no longer serve as public ceilings.
Which models offer the highest cost efficiency?
There is a significant price spread between model families. The "mini" and "nano" variants, such as gpt-5.4-mini at $0.75 per 1M input tokens, provide a lower-cost alternative for high-volume tasks compared to the standard gpt-5.5 or gpt-5.6-sol models. Organizations must weigh the cost of "Long context" models, which can double the input price, against the specific requirements of their internal applications.
To determine if these API costs translate into a positive net return, organizations must look beyond the invoice and measure the specific time saved versus manual baselines. NetLift enables Finance and AI leaders to correlate token spend with evidence of productivity gains, ensuring that the premium paid for high-output models like gpt-5.5-pro is offset by verifiable efficiency improvements.
