Fireship: 'OpenAI is so back... GPT 5.6 Sol first look'
Fireship's rapid-fire first look at GPT-5.6 Sol on the day it went public, covering the three-tier lineup (Sol, Terra, Luna), the science focus, and how the new pricing lands next to Grok 4.5.
Fireship reacts to GPT-5.6 Sol on launch day and lines it up against Grok 4.5.
What is it?
A Fireship YouTube video, published the day GPT-5.6 went public, walks through OpenAI's new three-tier Sol/Terra/Luna family. The channel's usual short, high-density format covers what changed since GPT-5.5, the science-tuned Sol variant, and where the new pricing sits next to xAI's Grok 4.5.
How does it work?
Fireship narrates over side-by-side pricing tables, model-card excerpts, and demo runs, calling out the biology, chemistry, and cybersecurity slant of the Sol tier and how the mid-price Terra and cheap Luna variants replace GPT-5.5 in the lineup. Sound bites are kept to a few seconds each so the video reads as a rapid changelog rather than a review.
Why does it matter?
Fireship is one of the biggest changelog channels for working developers, so a launch-day video shapes the first impression a large chunk of the industry gets of GPT-5.6 Sol. The video also captures the current mood on the OpenAI-vs-xAI race between GPT-5.6 and Grok 4.5.
