Users report being routed to GPT-6 Sol, early impressions consistently positive

kimmonismus · x · 2026-09-15

Multiple users report that selecting 5.6 Sol now routes them to GPT-6 Sol, with consistently positive early impressions and notably fast speed.

Context from earlier rumors: GPT-6 Sol may be imminent, matching Tibo's claim that this week's major releases could fill a Dev Day. The author speculates Sol will sit below Astra in the tier (as Opus does below Fable), targeting much better value for money — near-Astra performance at lower cost. He's also excited for GPT-6 Luna, given how good 5.6 Luna was on price-performance.
