Model ML has integrated OpenAI's GPT-5.6 Sol into its agent platform to automate end-to-end financial analysis, including the creation of editable PowerPoint decks and Excel workbooks.
- GPT-5.6 Sol uses 21% fewer tokens per PowerPoint deck than Fable 5 and 36% fewer tokens per Excel workbook than Opus 5.
- The model achieved a 16.6 percentage-point lead in professional readiness over Opus 5, clearing the review-ready gate in 43.3% of cases compared to 26.7%.
- Bespoke tearsheet generation time was reduced from approximately one hour to five minutes at one global asset manager.
- The platform supports surface-agnostic workflows, allowing users to start assignments in email or the app and continue via Microsoft Office plug-ins.
This integration allows finance professionals to focus on judgment and message refinement rather than manual formatting, as the agent produces traceable, editable files ready for scrutiny.
