Top LLM Use Cases

Practical use cases with realistic model selection patterns.

Current stacks (May 23, 2026): Combine Claude Opus 4.7 (agentic) or GPT-5 Turbo (live data + video) with Claude Sonnet 4.6 for premium tier; o4-mini, Gemini 3.5 Flash, or Gemma 4 for high-volume; Qwen3.5-35B-A3B (MoE coding), Llama 4 Scout, Gemma 4, or DeepSeek R1 for private and cost-optimized deployments. Agentic workflows now mainstream in enterprise. Llama 4 Maverick brings visual reasoning to private deployments.

Customer Support

Use a high-quality model for escalations and a low-cost model for first-pass triage.

Software Engineering

Use top coding-capable models for implementation and refactoring assistants with policy filters.

Operations and Back Office

Batch summarize tickets, invoices, and updates with cost-optimized models and strict validation. Gemma 4 is a strong option when teams want lower-cost private inference.

Legal and Compliance

Prefer high-context, careful models with auditable prompts and human-in-the-loop approval.

Healthcare Admin

Use de-identification pipelines and model gating. Keep clinical decision-making outside autonomous LLM action.

Finance Workflows

Use retrieval + deterministic validators to reduce hallucinations in reports and internal analyses.
