Head-to-head comparisons of LLM providers — pricing per million tokens, context windows, throughput, use case fit. Updated for 2026 model lineups (Claude 4.5, GPT-5, Gemini 2.5, Mistral Large 2.5).
Vendor Integrations 25 providers
Each LLM provider supported via VerticalAPI BYOK — integration guide, model lineup, pricing, regional availability. Same OpenAI-compatible endpoint, you bring your own API keys.

Use Cases 10+ guides
Tool calling, function calling, RAG, multi-modal vision, structured outputs, long-context analysis, code generation — practical guides with copy-paste code examples for each workload.
