What's this about?
GPT-6.1 Sol is OpenAI's lower-cost workhorse for coding, computer use and professional documents. It costs $2 per million input tokens, $0.10 for cached input and $10 for output.
What exactly is cached input?
Agents repeatedly resend the same code, instructions and history. A provider can reuse earlier computation for that repeated prefix and charge less—like keeping reference books open instead of fetching them again.
What's the community saying?
17,640 likes on the launch; focused search found independent tests with more than 1,000 likes.
- Early users reported near-Astra bug-fixing results at much lower cost, though samples were small.
- Benchmark disagreement showed that harness choice can materially change model rankings.
- Some users preferred Sol to the more visible Dots launch because economics directly affect everyday agent use.
