What is and isn’t public

An evidence-based summary of what this catalog has documented. It is not a verdict on the organization as a whole.

Perplexity's main products are a hosted assistant and hosted APIs. It also publishes some model weights on Hugging Face, such as the pplx-embed text embedding models, which the model card lists under the MIT license and describes as derived from Qwen3 through continued pretraining by Perplexity.346

Products

Documented products and how they are delivered. Each row links to the official page.

Hosted model products

Labeled Hosted product/API — this describes how a documented product is delivered (hosted access). It does not determine whether underlying weights or code are open; assess the specific release and its licenses.

  1. · Release

    Perplexity releases pplx-embed-v2-late multimodal late-interaction embedding models under MIT

    Perplexity has published pplx-embed-v2-late, a family of multimodal late-interaction (ColBERT) retrievers for text, images, and visual documents built on Qwen3.5 with bidirectional attention, in 0.6B and 9B sizes on Hugging Face under the MIT license. The model card says both models produce one 128-dimensional vector per token, share an embedding space so the 0.6B model can query an index built with the 9B model, and were distilled from an internal 18B ColBERT teacher. The card's citation dates the accompanying Perplexity blog post October 7, 2026. Perplexity also published pplx-embed-v2-context-9b-preview, a contextual embedding model for document chunks that its card labels a preview whose weights and interface may change. USASI has not tested these models.

  2. · Release

    Perplexity releases pplx-decider open-weight decision models under Apache 2.0

    In October 2026 Perplexity published pplx-decider-v1-27b on Hugging Face, a decision model fine-tuned from Qwen3.8-27B that returns a selected choice with calibrated probabilities for text and image inputs; the weights are ungated and licensed under Apache 2.0. Perplexity's API changelog says its new Decisions API answers questions about text, JSON, or images with probabilities instead of generated text, using pplx-decider-v1-27b at POST /v1/decisions. A later changelog entry says pplx-decider-v1.1-27b replaces v1 as the Decisions API model; its model card says the update uses the same backbone, gets most of its gains from lifting the causal mask and training on more data, and ships as a separate decision head rather than a full-vocabulary language-model head. USASI has not tested these models.
