Model ML Taps GPT-5.6 Sol to Streamline Finance Work

Model ML is applying artificial intelligence to the labor-intensive workflows used by financial-services teams, spanning initial research and analysis through final client deliverables. Its platform can produce editable, traceable PowerPoint presentations and Excel workbooks, allowing analysts to review assumptions and revise outputs. The approach matters because finance requires both speed and auditability, making reliable document creation a key test of whether large language models can move beyond drafting into end-to-end professional work.

Following OpenAI’s July 9, 2026 launch of the GPT-5.6 family, Model ML adopted flagship model GPT-5.6 Sol for finance workflows. In Model ML’s FinBench evaluation, covering 20 challenging client workflows and hundreds of presentation decks, Sol used 39% fewer tokens per deck than Fable. Model ML said it also produced clearer, more accurate data visualizations and required less rework before sharing. OpenAI priced Sol API usage at $5 per million input tokens and $30 per million output tokens.
