Difficult Problems Evaluation Sprint
Find the mistakes your AI doesn't know it's making.
A professional evaluation service for one defined AI system, agent, workflow, or model implementation. We test the difficult reasoning required by its intended work, not merely whether it produces fluent output.
The problem
An AI can sound plausible while missing a critical fact, failing to ask for needed information, overstating certainty, or recommending the wrong next action. Those are professional reasoning failures, not style issues.
Evidence from a local-model demonstration
In a 22-case local-model demonstration, two different models both failed 20 of the 22 difficult professional-reasoning cases under the evaluation framework. Eight of the most commercially meaningful failures were reviewed by Sonny Saggar, and all eight were confirmed as genuine failures.
This was a local-model demonstration. It does not claim that all AI systems perform the same way. GPT, Claude, and Gemini were not part of this completed local comparison.
What we test
We evaluate a defined AI system, agent, RAG workflow, or AI-assisted process against purpose-built difficult reasoning cases relevant to its job.
- Critical facts, missing information, and contradictory evidence
- Unjustified confidence, poor grounding, and fabricated facts
- Priority decisions, professional-domain boundaries, and changed-fact failures
- Appropriate next actions when a system should not proceed
What you receive
- A baseline evaluation of one defined system, agent, workflow, or model implementation
- Approximately 25 purpose-built difficult reasoning cases
- Structured failure analysis
- A Reasoning Failure Report
- Remediation recommendations
- One re-test after agreed fixes
Founding-client price
$7,500 for the bounded founding-client scope described above. This is a professional evaluation service, not generic model benchmarking. Scope is agreed before work begins.

How this relates to the corpus
The Difficult Problems Corpus supplies a disciplined private methodology for evaluating difficult reasoning. It does not make private cases publicly available.
Start an evaluation
Tell us the organization, system or workflow, domain, intended work, highest-consequence failure you worry about, and whether system access can be provided. Initial inquiries should not include confidential records, protected health information, privileged material, or other sensitive documents.
