Define the decision
Turn a vendor or model search into a workload, acceptance boundary and evidence plan before demonstrations begin.
Technical buyer desk
Buy evidence, not an AI demo.
Vendor-neutral guides for teams deciding which AI systems deserve a trial, what must block deployment and what evidence belongs in the purchase record.
Decision path
Move from requirement to bounded trial.
These steps are AccessAllGPT guidance, not an empirical vendor ranking. Adapt the sequence to your workload, data classification, regulation and failure tolerance.
Test the configured system
Evaluate the model, prompts, tools, permissions and human interventions as one production-shaped system.
Clear security gates
Treat repository and tool access as authority decisions, with explicit controls that a strong aggregate score cannot offset.
Buyer guides
Record the decision before the contract.
Use the framework to precommit criteria, preserve trial evidence and make security, operations, economics and exit risk reviewable.

AI API Data Retention and Residency: Set the Procurement Gates
Approve, constrain, test or reject one configured data path
“No training” is not a retention policy, and a region selector is not a complete data map. Use this evidence-led review to gate an AI API on storage, processing, logs, application state, transfers and deletion.

LLM Evaluation Platforms: Keep the Decision Contract Portable
Build, buy or extend without trapping the evidence in one dashboard
Choose an LLM evaluation platform by what you can export, reproduce and migrate—not by grader count. Own the cases, decision rules, provenance and case-level results before adopting a workflow or dashboard.

LLM Observability: Build the Evidence Layer Before You Buy the Dashboard
A build, buy or hybrid decision for production AI telemetry
Decide what evidence an AI system must produce, which content may be retained, and whether your existing stack, a specialist platform or a hybrid can meet the operating contract.

RAG vs Fine-Tuning: Choose the Right Adaptation Path
A production decision for knowledge, behavior and combined systems
Retrieval and fine-tuning solve different failure classes. Use this evidence-led decision to choose prompt-only, RAG, fine-tuning, a measured combination—or no LLM change.

The AI Tooling Procurement Scorecard

Managed LLM API vs Self-Hosting: Make the Production Decision
A build, buy or bounded-trial framework for one AI workload
Compare a managed model API with a self-hosted open-weight stack on accepted outcomes, full operating cost, data boundaries, control and exit—not token price or infrastructure ideology.
