Support beats features every time - the real ai vendor evaluation checklist

Every ai vendor evaluation checklist I see starts the same way. Model benchmarks, API pricing, feature matrices.

Wrong place to start.

MIT research found that 95% of generative AI pilots at companies are failing. The study analyzed 300 public AI deployments and conducted 150 interviews with leaders. The pattern? Technical capability wasn’t the issue. Implementation support was.

When your AI deployment breaks at 3am and you’re bleeding money by the minute, those benchmark scores don’t matter. What matters is whether anyone answers the phone.

Why standard vendor comparisons miss the point

I’ve watched companies spend months building elaborate scorecards comparing model accuracy, throughput metrics, and pricing tiers. They create weighted matrices. Run pilot tests. Build business cases.

Then they pick a vendor and everything falls apart during implementation.

Over half of C-suite executives report dissatisfaction with AI vendors. But here’s the thing - they’re not complaining about the technology. They’re frustrated because 52% say vendors should do more to help define roles and responsibilities, address security considerations, and train their teams.

The vendors sold them on features. Nobody mentioned you’d be mostly on your own figuring out how to actually use them.

This gap between what vendors promise and what they deliver shows up everywhere. Constellation Research) found that 42% of enterprises deployed AI without seeing any ROI. Not because the AI couldn’t do the job - because organizations couldn’t bridge the gap from pilot to production.

What actually determines success

The best predictor of AI implementation success isn’t model performance. It’s vendor support quality.

Look at what works. Companies that purchase AI tools from specialized vendors and build partnerships succeed about 67% of the time. Internal builds? They succeed only 33% of the time.

The difference isn’t technical. It’s support.

Real implementation support means vendors who help with data preparation, integration architecture, team training, and change management. Not just documentation and chatbots. Actual humans who understand your environment and help you navigate the inevitable problems.

Lumen Technologies saw their sales teams spend four hours researching customer backgrounds before outreach calls. After implementing AI with proper vendor support, they compressed that to 15 minutes. The technology enabled it. The vendor support made it real.

Air India built AI.g, their generative AI assistant handling routine queries in four languages. The system now processes over 4 million queries with 97% automation. They succeeded because their implementation partner helped them through the messy middle - data cleanup, integration testing, user adoption.

The pattern holds. Success requires vendors who stick around after the contract signature.

The ai vendor evaluation checklist that matters

Forget starting with features. Start here.

Support response structure: What’s the actual response time for critical issues? Not the marketing page promises - the SLA. Response times for critical issues should be under 3 hours for production outages. Some vendors promise this. Many don’t deliver it.

Ask for references from companies at your scale who’ve had production incidents. Call them. Find out what actually happened when things broke.

Implementation partnership depth: Will they help you prepare data, design integration architecture, and train teams? Or do they hand you API docs and wish you luck?

The 52% of executives wanting more implementation help aren’t asking for the moon. They want vendors to help define roles, address security, and provide training. Basic stuff. Many vendors won’t do it.

Integration ecosystem maturity: How well does their platform work with your existing systems? Nearly 60% of organizations cite integrating with legacy systems as their primary AI adoption challenge.

This isn’t about whether integration is technically possible. It’s about whether the vendor has done it before in environments like yours and can guide you through the gotchas.

Lock-in escape hatches: What happens when you need to leave? Vendor lock-in creates cascading risks beyond switching costs. You lose negotiating leverage, face inflated renewal pricing, and sacrifice architectural flexibility.

A healthcare provider deployed OpenAI’s GPT APIs for patient support and clinical note summarization. Only later did they realize shifting to a more compliant or cost-effective alternative would require rebuilding everything. The integration was too deep, the data too embedded.

Ask about data portability, model interoperability, and exit procedures before you sign anything.

Pricing transparency and sustainability: Do you understand not just current pricing but how costs scale? Many vendors offer attractive pilot pricing that becomes unsustainable at production volume.

Look for vendors with clear pricing models and usage forecasting tools. The wrong pricing structure can make a working AI system economically unviable.

Building resilience through diversification

37% of enterprises now deploy 5+ specialized AI models across their operations. This isn’t complexity for its own sake. It’s risk management.

Single-vendor strategies create fragility. When Anthropic’s market share jumped from 12% to 32% while OpenAI dropped from 50% to 25%, it happened because enterprises diversified. They learned that betting everything on one vendor leaves you exposed.

Different use cases need different models anyway. Anthropic dominates coding with 42% market share. Google pushes interoperability with their Agent-to-Agent protocol. OpenAI focuses on unified developer experiences. Microsoft integrates deeply with Office.

Match vendors to specific use cases rather than forcing one vendor to handle everything. Then build your ai vendor evaluation checklist around ensuring each vendor relationship includes the support depth needed for that use case.

The companies succeeding with AI aren’t necessarily using the most advanced models. They’re using models they can actually implement and support, often with help from vendors who treat implementation as a partnership rather than a transaction.

Making it stick

Your ai vendor evaluation checklist needs one more thing: a plan for maintaining leverage.

Vendor relationships shift. Switching costs become massive barriers when AI systems embed deeply into operations. You end up with entire training datasets, memory states, and vector stores tied to one platform.

Build architecture that lets you shift if needed. This means:

• Standardizing on open formats for training data and model outputs
• Designing integration layers that abstract vendor-specific APIs
• Maintaining capability to run inference workloads on alternative platforms
• Documenting dependencies so switching is possible even if expensive

A global bank built risk analytics entirely around AWS-native services. Migrating to Azure or GCP would require rewriting components, revalidating compliance, and retraining teams. The switching costs made them effectively locked in, eliminating their negotiating position.

Don’t build that trap for yourself.

The goal isn’t to avoid commitment. It’s to maintain the option to leave if vendor support quality deteriorates, pricing becomes predatory, or better alternatives emerge.

Most standard vendor comparisons won’t tell you this. They’ll show you which model scores highest on benchmarks while ignoring the fact that 88% of AI proof-of-concepts fail to reach production.

The companies that beat those odds don’t have better technology. They have better vendor partnerships built on realistic expectations about implementation support.

Start your ai vendor evaluation checklist there. Everything else follows.
