ChatGPT handles some CRE tasks well. A different set than you'd expect.

File upload behavior, context window limits in practice, the Code Interpreter difference, and the setup choices that affect output quality – standard chat vs. Projects vs. API vs. custom GPT.

Prompt sequence for rent roll ingestion, expiration extraction, and summary table output. Code Interpreter results vs. standard chat results on messy formats. Known failure modes and the verification steps that catch them.

Field-by-field abstraction prompt structure. Where ChatGPT performs reliably, where it hedges or hallucinates, and the prompt modifications that improve consistency on complex lease structures. Output template included.

Converting seller-prepared statements into standard format using Code Interpreter. Non-recurring identification, management fee treatment, below-the-line items. Tested against multiple seller-prepared formats.

Summarizing comp packages, running Q&A against loan and due-diligence documents, and first-pass narrative drafting. Where ChatGPT's drafting style is an asset. Where it introduces fluency-over-accuracy errors to watch for.

Direct comparison with Claude on the six workflow modules. A task-routing framework: which workflows run better in ChatGPT, which run better in Claude, and which are close enough that the model choice doesn't matter.

For the file-upload workflows, GPT-4o access, and Code Interpreter capability, yes – ChatGPT Plus ($20/month) or an OpenAI API key. The brief notes where free GPT-3.5 access is sufficient and where it isn't. Most of the workflows covered require Plus.

The brief covers both access paths where behavior differs. API access gives you more control over context and model version; ChatGPT.com's interface gives you easier file handling. Where the distinction matters for CRE tasks, it's noted.

The two guides use the same workflow structure and document types so outputs are directly comparable. Section VI of each guide covers the cross-model comparison explicitly. You can read either guide independently or use both together to build a model-routing practice.

Out of scope for the brief – that's a firm policy and legal question. Review OpenAI's usage policies and your firm's AI use guidelines before uploading deal-specific documents. The brief focuses on workflow and output quality, not data governance.

Yes. Point updates will track major GPT model releases and any changes to ChatGPT's file handling or tool availability. Free for 12 months with Dispatch sign-up.

No. It's a practitioner assessment of a specific tool on specific tasks. Valore Registry has no commercial relationship with OpenAI. The guide documents what works, what doesn't, and when a different tool earns the workflow.
