What AI models does Jasper use?

Question

Accepted Answer

Jasper runs on ChatGPT (OpenAI), Claude (Anthropic), General Purpose LLMs (Multiple Providers), GPT-5.2 (OpenAI), Jasper AI Engine (LLM routing multi-model) (Jasper), Jasper AI Engine (LLM-agnostic routing) (Jasper), Jasper AI Engine (Multi-LLM) (Jasper), Jasper Engine (multi-LLM routing) (Jasper), Jasper Engine (Multi-model routing) (Jasper), Jasper's LLM-Optimized Architecture (Multi-LLM Routing) (Jasper), Jasper's LLM-Optimized Architecture (Multiple LLMs) (Jasper), LLM Routing (Multi-Model Engine) (Jasper), LLM Routing (Multi-model) (Jasper AI Engine), LLM Routing & Maintenance (Several LLMs) (Multi-provider), LLM-agnostic / Multi-LLM Routing (Multi-provider), LLM-agnostic / Multi-model routing (Provider undisclosed), LLM-Optimized Architecture (Multi-Model) (Jasper), LLM-Optimized Multi-Model Architecture (Jasper), multi-LLM engine (Jasper AI), Multiple LLMs (routed) (Multi-provider), Multiple models (LLM-agnostic / proprietary routing) (Jasper AI Engine) and proprietary marketing knowledge layer atop general purpose LLMs (Jasper), and routes requests between them. Model claims are labelled by how we know them: ChatGPT — inferred, Claude — inferred, General Purpose LLMs — unknown, GPT-5.2 — inferred, Jasper AI Engine (LLM routing multi-model) — inferred, Jasper AI Engine (LLM-agnostic routing) — inferred, Jasper AI Engine (Multi-LLM) — inferred, Jasper Engine (multi-LLM routing) — inferred, Jasper Engine (Multi-model routing) — inferred, Jasper's LLM-Optimized Architecture (Multi-LLM Routing) — inferred, Jasper's LLM-Optimized Architecture (Multiple LLMs) — inferred, LLM Routing (Multi-Model Engine) — inferred, LLM Routing (Multi-model) — inferred, LLM Routing & Maintenance (Several LLMs) — inferred, LLM-agnostic / Multi-LLM Routing — inferred, LLM-agnostic / Multi-model routing — inferred, LLM-Optimized Architecture (Multi-Model) — inferred, LLM-Optimized Multi-Model Architecture — inferred, multi-LLM engine — inferred, Multiple LLMs (routed) — inferred, Multiple models (LLM-agnostic / proprietary routing) — inferred and proprietary marketing knowledge layer atop general purpose LLMs — inferred. "Disclosed" means the vendor says so in public; "inferred" means it was derived from documentation, headers or release notes. Context window: Not published. Other stack signals: AI Content Generation, AI Agents and SEO Optimizer.
