Features Comparison

Cerebras

Wafer-Scale Inference
Models run on the Cerebras Wafer-Scale Engine, which keeps model weights in on-chip SRAM to reach published speeds in the thousands of tokens per second
OpenAI-Compatible API
Chat Completions and Completions endpoints at api.cerebras.ai/v1, usable from the OpenAI SDKs or the Cerebras Python and TypeScript SDKs
Open-Weight Model Catalog
Public endpoints serve unmodified open-weight models such as OpenAI GPT OSS and Qwen, with a documented policy of no pruning on hosted models
Reasoning and Tool Calling
Configurable reasoning effort, streaming, structured outputs, parallel tool calling, and prompt caching across the catalog
Image Inputs
Vision-capable models accept PNG and JPEG images alongside text
Dedicated Endpoints
Private, provisioned endpoints on reserved capacity with fine-tuning, weight management, and additional model families, arranged through sales

Perplexity

Sonar Search Models
Proprietary models combining LLM reasoning with real-time web search and citations
Online Grounding
Responses include inline citations and sources from live web data
OpenAI-Compatible API
Drop-in replacement using standard chat completions format
Open-Source Models
Access to Llama and other open-source models alongside Sonar
Structured Outputs
JSON mode and structured output support for reliable parsing
Search Domain Filtering
Restrict or focus web search to specific domains for targeted results

Pros & Cons

Cerebras

Advantages

Published throughput in the thousands of tokens per second on public models
Drop-in OpenAI-compatible API with first-party Python and TypeScript SDKs
Serves original, unpruned open-weight models with a stated no-modification policy
Free trial credits on signup, then self-serve pay-as-you-go

Considerations

Very small public model catalog compared with GPU-based inference providers
Free-tier context windows are roughly half the paid-tier limits
Preview models can be withdrawn and are not intended for production use

Perplexity

Advantages

Unique search-augmented generation with real-time web data
Built-in citations reduce hallucination risk
OpenAI-compatible API for easy integration
Competitive pricing on open-source model hosting

Considerations

Smaller model selection than general-purpose platforms
Search-augmented models have higher per-request costs
Less mature enterprise offering compared to larger providers
