OpenAI Launches GPT-6 Models, Deepening AI Price War
How low will the OpenAI GPT 5.5 output token price get in 2026?
Kalshi prices this $15/MTok or below at 58%. The reporting broadly agrees.
OpenAI has launched its new GPT-6 Sol and GPT-6 Luna models, which boast lower costs and improved performance, intensifying the ongoing price war in the artificial intelligence sector. Multiple outlets report that these new models come with a 50% reduction in API pricing, a move that follows closely on the heels of Anthropic's release of a cheaper flagship model. This rapid succession of releases and price cuts suggests a fierce competition among leading AI developers, all vying for market share by offering more cost-effective solutions. The market, which has seen its odds climb over the tracking period, currently places the probability of OpenAI GPT 5.5 output token price reaching $15/MTok or below in 2026 at 58%, reflecting a strong expectation of continued price compression.
Background
The competition among AI developers, particularly between OpenAI and Anthropic, has been characterized by a series of aggressive price reductions and new model introductions. Earlier this year, OpenAI had already cut prices by 50% on its mid-tier models on the same day Anthropic shipped a cheaper flagship, highlighting a rivalry where pricing adjustments are measured in minutes. The market tracks whether the output token price of OpenAI GPT 5.5 will reach or fall below $15 per megatoken in 2026, a threshold that would signify a substantial cost reduction for users of the technology.
