⬤ OpenAI's Polaris-Alpha model—believed to be GPT-5.1—is turning heads with strong early test performance and unusually high rate limits. The emphasis on efficiency makes sense given compute constraints remain the company's biggest challenge. As OpenAI buys compute wherever available, building more efficient models becomes the logical path forward.
⬤ Benchmark screenshots place Polaris-Alpha at the top of Creative Writing v3 and among leaders in Longform Creative Writing. A model-tree visualization clusters it close to GPT-5-series outputs, confirming the system competes well on writing tasks while maintaining those high rate limits.
⬤ According to Sam Paech writing evaluations, a "stealthed" OpenRouter model named Polaris-Alpha outputs cluster nearest to GPT-5 with very high rate limits—pointing to this likely being GPT-5.1.
⬤ The focus on efficiency and rate limits matters because it determines how quickly advanced models can scale under tight compute conditions. While release details remain unclear, OpenAI continues pushing toward strong performance with better efficiency—a shift that could reshape platform usage, costs, and competitive dynamics across AI.
