About GPT-6.1 Sol
Key Strengths
- OpenAI says it nearly matches GPT-6 Astra on agentic coding, computer use and professional work at one-fifth of Astra's token prices
- Artificial Analysis puts it 1 point below GPT-6 Astra on its Intelligence Index at under a quarter of the cost per task
- Cached input is $0.10 per million tokens (95% off standard input), which helps agents that reuse context
Limitations to Consider
- Artificial Analysis measured about 10–30% more output tokens than GPT-6 Sol
- In ChatGPT it's limited to paid tiers in ChatGPT Work and Codex, not regular Chat
- GPT-6 Astra still leads on the hardest science tasks, and HN commenters report lower subscription allowances that offset the cheaper price for Codex users
