GPT-6 Sol
Cheaper mid-tier GPT-6 model for coding and agentic workloads at $2/$10 per M input/output tokens.
Why it matters
50% cheaper than GPT-5.6 with faster inference via better caching, purpose-built for coding and agentic workloads.
What you could build with it
Benchmark it as the code-review model for a week: at $2/$10 per M tokens it is priced to replace heavier models on routine review tasks.
Does it hold up?
Builders already treat Sol as the coordination and harder-implementation slot, but the evidence is young routing repos, not production benchmarks.
Built with GPT-6 Sol
- GitHub added GPT-6 Sol and Luna to Copilot on launch daydev.to · Day-one third-party integration: both models shipped in GitHub Copilot with usage-based billing.
- GPT-6 Sol vs Luna: best value per taskvanda team · Independent cost-per-task routing analysis across Luna, Sol and Opus 5.5 with measured savings.
- breko861-hash/sol-luna-codex-orchestratorgithub · 65 ★ · Cost-aware Codex orchestration; Sol acts as parent/reviewer or the harder bounded worker.
- Lisuiwen/GPT-Astra-delegatorgithub · 1 ★ · Routes exploration to Luna, straightforward implementation and mechanical edits to Sol.
- skyyy-Xu/choose-gpt-5-6-modelgithub · 1 ★ · Work-package routing across GPT-6 Astra and GPT-5.6 Sol, Terra and Luna.
