R to @OpenAI: Plus and Pro users can access the updated version of GPT‑5.6 Sol in ChatGPT along…

TL;DR - OpenAI is rolling out an updated GPT‑5.6 Sol to ChatGPT Plus and Pro users, alongside a new response-control slider, while expanding GPT‑5.6 Luna access for free users. It matters as a product-tier segmentation signal: the same model name now ships in different tuned variants per surface.

• The updated GPT‑5.6 Sol is scoped to the Chat experience only; the Sol variant powering Work and Codex is unchanged by this release.
• A new "slider" ships with it, implying user-adjustable behavior (per the linked post, aimed at everyday chat quality) rather than a separate model selection.
• OpenAI's linked announcement claims improved accuracy and consistency for Sol, plus expanded/unlimited everyday chat access to GPT‑5.6 Luna for free users.
• Content is a short announcement post with no benchmarks or eval details provided, so the accuracy/consistency claims are unquantified here.
