Model ML completes finance work more efficiently with GPT-5.6 Sol

TL;DR - OpenAI customer story on Model ML, a finance-focused platform using GPT-5.6 Sol to automate analyst workflows end-to-end, from research through generated PowerPoint decks and Excel workbooks. It matters as a concrete example of frontier LLMs moving beyond chat into deliverable-producing, auditable enterprise workflows.

• Covers the full analyst pipeline — research and analysis through final artifact generation — rather than a single isolated task.
• Outputs are native, editable PowerPoint and Excel files, not static text, implying structured tool/document generation rather than free-form completion.
• Emphasizes traceability, a key requirement for finance where outputs must be sourced and audited.
• Content is thin (a single promotional summary); no benchmarks, accuracy figures, or efficiency metrics are provided, so the "more efficiently" claim is unquantified here.
