| Price in/out ($/M) | $5 / $30 | $5 / $30 |

## Our verdict

Identical list price ($5 / $30 per M tokens) and nearly double the context (1.05M vs 600K), so for large-codebase refactors and long-horizon agents Sol is a straight upgrade. There is one catch worth checking before you migrate: GPT-5.5 is natively multimodal with realtime voice and video, and Sol takes text and vision only. If your product listens or speaks, GPT-5.5 stays. We do not publish a benchmark table for Sol because OpenAI's own figures and independent evaluations disagree by several points, so run both against your evals rather than trusting either number.
