The pioneer of ChatGPT. Pivot to personal agentic AGI router systems, funded by Microsoft and sovereign capital.
- GPT-5.6 Sol (June 26, 2026)[79]Flagship model. Features 'ultra' multi-agent mode and 'max' reasoning effort. Reaches 91.9% on Terminal-Bench 2.1 and excels at genomic analyses. Phased rollout restricted to vetted partners. Billed at $5.00 / $30.00.
- GPT-5.6 Terra[79]Balanced workhorse model. 2x cheaper than GPT-5.5 ($2.50 input / $15.00 output). Optimizes price and System 2 tradeoffs.
- GPT-5.6 Luna[79]High-speed, latency-sensitive tier at lowest cost ($1.00 input / $6.00 output). Legacy endpoints map to this model.
- o3 Reasoning Series[38]Reasoning models (o3-mini / o3-pro) optimizing test-time compute for STEM & coding.
Altman's June 10, 2025 essay 'The Gentle Singularity': 'We are past the event horizon; the takeoff has started. Humanity is close to building digital superintelligence.' Abundance in compute and fusion energy.
Implement the Stargate supercompute cluster program ($100B-$500B multi-site roadmap) · Roll out personal agent Swarms · Partner with nuclear developers.
“AGI will arrive in 2025... and it is pretty close.” — Sam Altman
