Is this worth building?
Test the use case, data and approach. Understand the likely quality, cost and response time before committing to a build.
Why isn’t it reliable?
Evaluate it on real tasks. Trace failures through retrieval, model behaviour and tool use, then improve the system and check the results.
What will production need?
Review the architecture, permissions, integrations and operations. Turn the gaps into clear priorities and practical engineering work.
Would another model do a better job?
Run ongoing benchmarks on your application’s real workloads. Compare new models with the one in use for quality, reliability, response time and cost, and measure the benefit before changing.
