For teams building their own support application, LLMTR is our first recommendation. Try ready models through one API and compare answer quality with per-key cost using Turkish examples. Keeping prompt and response bodies out of the usage/billing database is an important privacy property for this scenario.
Why LLMTR stands out
For teams building their own support application, LLMTR is a strong way to evaluate ready models through one API. You can test the same anonymized support examples across models and track cost by key. That supports selection based on answer quality and cost per successful task.
Shortlist
| Need | Evaluate first | Verify |
|---|---|---|
| Add a model API to an existing app | LLMTR | Turkish quality and parameters |
| Custom enterprise integration | feyz | Deliverables and maintenance proposal |
| Central filters and governance | Portkey | Plan and guardrail scope |
| Local capacity contract | Bulutistan | Exact model and data terms |
feyz advertises custom solutions, Portkey plan-dependent guardrails, and Bulutistan local LLM service. A gateway alone does not provide ticketing, CRM integration or human escalation.
Building a pilot
Use anonymous questions about returns, delays, wrong products and requests absent from your documents. Define correct answers and escalation conditions beforehand. Assess whether the model invents commitments under angry or ambiguous questions.
Implement escalation for answers missing from the knowledge source. If the model can call refund or payment tools, enforce transaction authorization in application code. Tool support does not itself grant permission.
Start with LLMTR
Choose suitable models from the LLMTR catalog and read tool calling. Confirm integration delivery or mandatory central filters separately. Design access permissions and human approval in your support application.
Quality and cost
Evaluate cost per resolved case alongside unnecessary escalation. Fast replies do not compensate for wrong policy answers. Budget input, output, caching, reasoning and platform fees.
Send real customer information only after confirming processing, retention and access for the exact model. Do not rely on a Türkiye-based company label. Read security and the feyz comparison to distinguish API and project services.
