Prediction markets put the probability at 87%: Will the next model released by OpenAI debut at a score of at least 1450. Currently, markets see this as likely (87% YES). Meta's AI chief, Alexandr Wang, says its coming Watermelon AI model now matches OpenAI's GPT-5.5.
Whether the next model released by OpenAI debut at a score of at least 1450 hinges on the lab's accelerating release cadence. OpenAI previewed GPT-5.6 Sol last week, described as its most agentic model yet, following the flagship GPT-5.5 currently deployed. The company also rolled out its Sol, Terra, and Luna tier last month, signaling a rapid sequence of incremental upgrades rather than a single monolithic launch. Each successive release has posted higher benchmark figures, and reaching a 1450 debut score would extend a trajectory the lab has maintained across its 5.x generation. [The Neuron, Jun 28]
Competitive pressure is intensifying. Meta's AI chief Alexandr Wang told an internal town hall on July 2, 2026 that the company's upcoming model, codenamed Watermelon, has "caught up" with GPT-5.5, adding that Watermelon uses "an order of magnitude more compute" than its predecessor Avocado. Anthropic, meanwhile, released Claude Sonnet 5 on June 30 as a cheaper agentic option and cleared Mythos 5 for vetted US organizations. The clustering of top-tier launches raises the bar OpenAI faces, and factors into whether the next model released by OpenAI debut at a score of at least 1450 when it ships. [Business Insider, Jul 2]
The stakes extend beyond benchmarks. OpenAI is reportedly delaying its IPO to 2027 despite filing a confidential S-1 and launching ChatGPT ads, while Washington asserts tighter oversight of frontier labs. A strong debut for the next model — clearing the 1450 threshold — would reinforce OpenAI's positioning as one of the two labs defining AI's next phase. The immediate question is timing: with Sol still in preview and rivals shipping monthly, the next model released by OpenAI debut at a score of at least 1450 depends on when the full version exits preview and how it benchmarks against Watermelon and Mythos 5.
