GPT-6.1 Sol
OpenAI's mid tier, pitched as near-Astra performance for complex work at a fifth of the price. It replaced GPT-6 Sol a week after that model launched, at the same $2 / $10 with cheaper cached input.
Model ID: gpt-6.1-sol
What that means
A worked example
Per-token pricing is hard to feel. Take a moderately chatty production workload: 100 calls a day, roughly 10,000 tokens in and 2,000 out each time. On GPT-6.1 Sol that comes to about:
$120 / month
Before caching, batching or volume discounts, all of which move this number a long way. Illustrative only.
