Why Claude for this
Model choice is an engineering decision with a cost curve attached. We route across providers by task, so you are not paying frontier prices for work a smaller model handles perfectly.
Claude is strongest at sustained reasoning over long documents, careful tool use, and a low rate of confident errors. For llm application development that matters because the failure modes of this kind of system tend to cluster exactly there.
The honest trade-off: for very high-volume classification or extraction, a smaller model is cheaper at indistinguishable quality. We say that up front because a stack chosen for fashion rather than fit becomes someone's migration project two years later. We start from the constraint, not the capability, what the system must never do, who signs off, and what happens when it is wrong.
You own the code, the models where they are open-weight, and the documentation to run it without us.

We are not a reseller for Anthropic and hold no commission on this choice. Where a different option fits your workload better, the recommendation will say so. That is the entire value of asking us.
What is included

- Structured output and schema validation
- Evaluation suite run on every change
- Token cost monitoring and budget controls
- Streaming UX and graceful degradation
Questions
Which model should we use?
It depends on the task, not on the leaderboard. We benchmark your actual workload across providers and usually end up routing, a strong model for reasoning, a cheaper one for classification and extraction.
How do you control the token cost?
Caching, routing, prompt compression and hard budget ceilings, with per-feature cost monitoring so a runaway loop shows up in hours rather than on the monthly invoice.
Can you work with our existing codebase?
Yes. Most of our LLM work lands inside an existing product rather than as a greenfield app, and we match the conventions already in your repository.
Alternatives for llm application development
Same capability, different stack. Each page states its own trade-off.
