A widely shared chart plots the hype cycles of dozens of LLMs from June 2025 to November 2026, with each curve tracing a model's rise and fall — GPT-4, Opus 3, Sonnet 3.5, o1, DeepSeek R1, Gemini 2.5 Pro, Grok 4, Sonnet 4.5, Kimi K2 and more each peak for a couple of months.

The right half extends into speculation with unreleased fictional models: Gemini 3 Pro, the Opus 4.x series, GPT-5.6 Sol, Fable 5, Opus 5.5 and GPT-6 Astra, ending with Fable 5 towering above everything before Opus 5.5 claws back — a playful, prophetic parody of the post-GPT-5 landscape.
