      Frequently Asked Questions

      General

      Can custom LLMs generate multilingual content?

      Yes. Custom LLMs can generate multilingual content if trained with enough relevant data for each language.

      What is the difference between LLM fine-tuning and training from scratch?

      Fine-tuning adapts an existing LLM with domain-specific data, while training from scratch builds a new model entirely from raw data.

      How is the pricing for custom LLM development determined?

      Custom LLM pricing depends on factors such as project complexity, data volume, model size, and development effort.

      What is in-context learning in LLMs?

      In-context learning improves LLMs by using context in prompts to enhance reasoning and accuracy without retraining.

      Can custom LLMs run on mobile devices?

      Yes. Custom LLMs can be optimized for mobile devices to run efficiently within hardware constraints.

      Does TechAhead offer a free consultation for custom LLMs?

      Yes. TechAhead offers a free consultation to discuss custom LLM use cases and design tailored solutions.

      Which CRMs and platforms can custom LLMs connect to?

      Custom LLMs connect with Salesforce, HubSpot, Dynamics 365, Zendesk, ServiceNow, and custom ERPs via secure APIs.

      What is the cost structure for custom LLM projects?

      Projects include a one-time build cost plus ongoing infrastructure run-rate, with GPU usage optimized to reduce costs by 40–60%.

      How does TechAhead secure data in custom LLM projects?

      We secure custom LLMs using private VPCs, on-prem clusters, encryption, access controls, and compliance with SOC 2, HIPAA, GDPR, and PCI.

      How are custom LLMs monitored after launch?

      Custom LLMs are monitored using LLMOps pipelines to track drift, latency, accuracy, and cost, with automated retraining workflows.

      What ROI can businesses expect from custom LLMs?

      Businesses typically see 5–10× ROI within 12 months through faster workflows, higher conversions, and reduced operational costs.

      Which industries benefit most from custom LLM development?

      Healthcare, finance, ecommerce, SaaS, and customer service industries gain the most from compliant, domain-trained LLMs.

      What are the advantages of building a custom LLM instead of using APIs?

      Custom LLMs reduce long-term API costs, ensure data privacy, improve domain accuracy, and allow full control and customization.

      Where is TechAhead's custom LLM development team located, and do you serve international clients?

      TechAhead operates from USA (California), India (Noida), and UAE (Dubai). We serve global enterprises across North America, Europe, Middle East, Asia-Pacific, and Australia with 24/7 support and dedicated LLM engineering teams.
