Full comparison of Perplexity and Runway — live token pricing, latency, throughput, context window, strengths, weaknesses, and best use cases. Rates sourced from public APIs — verify before use.
Perplexity
Agent API, Router API, Search API, Embeddings API — Sonar deprecated Sept 27, 2026
Perplexity has restructured its API platform in 2026. Sonar Chat Completions is now the Agent API, which provides access to third-party models (OpenAI, Anthropic, Google, xAI, Z.AI, Moonshot AI, NVIDIA) at direct provider rates with no markup. The Router API routes requests across models with per-token billing. The Search API provides real-time web retrieval billed per request. The Embeddings API offers pplx-embed-v1 models. Sonar is deprecated September 27, 2026. Check docs.perplexity.ai/docs/getting-started/pricing for current rates.

Strengths and weaknesses
Perplexity
Runway
Key differentiators
An API platform combining real-time web search, multi-provider model routing (OpenAI, Anthropic, Google, xAI at direct rates), and purpose-built research tools under one key.
Gen-4 is Runway's cinematic-quality video generation model, trusted by professional film and advertising studios — with Gen-4 Turbo offering a faster, lower-cost alternative via the same API.
Frequently asked questions
Perplexity FAQs
What APIs does Perplexity offer in 2026?
Perplexity offers four APIs: Agent API (multi-step agentic tasks with third-party models at direct provider rates), Router API (intelligent model routing), Search API (real-time web retrieval, per-request billing), and Embeddings API (pplx-embed-v1 models). Check docs.perplexity.ai/docs/getting-started/pricing for current rates.
Is the original Sonar model still available?
No. The original Sonar Chat Completions API is deprecated as of September 27, 2026. It has been replaced by the Agent API. Migrate to the Agent API for continued access to search-augmented LLM capabilities.
What is the Perplexity Agent API?
The Agent API provides access to third-party models from OpenAI, Anthropic, Google, xAI, Z.AI, Moonshot AI, and NVIDIA at direct provider rates with no markup. It includes tools: web_search, fetch_url, people_search, and sandbox. Check docs.perplexity.ai for current tool rates.
Runway FAQs
How is Runway priced?
Runway charges per second of generated video. Gen-4 is $0.100/second and Gen-4 Turbo is $0.050/second. See runwayml.com/pricing for current rates.
What is Gen-4?
Gen-4 is Runway's latest video generation model, producing cinematic-quality output from text or image prompts. It is used in professional film, advertising, and visual effects production.
