## How they compare

Parasail and Cerebras solve opposite problems. Parasail aggregates GPUs from many hardware providers and sells them through one OpenAI-compatible API. Its standout is batch: any Hugging Face model, private repos included, at half of serverless pricing, with a 4B to 8B model at $0.03 in and $0.06 out at FP4. Cerebras owns its hardware, a wafer-scale chip, and uses it to serve GPT-OSS 120B near 3,000 tokens per second. Parasail will run nearly any checkpoint cheaply. Cerebras will run a very small set faster than any other public host.

For real-time traffic, Parasail designs around a 600ms p99 budget, but its consistency depends on the underlying providers. Cerebras runs on its own silicon, though the speed does little when an agent mostly waits on tools. Parasail's commit-to-spend model and ZDR agreements suit startups moving off closed APIs. Evals, embeddings and offline processing fit Parasail. Voice and live autocomplete fit Cerebras.

## What each one does

### Cerebras

Cerebras builds a single chip the size of a silicon wafer, and its inference cloud is the fastest public host on the models it serves. Its developer table lists GPT-OSS 120B near 3,000 tokens per second, about six times Groq on the same weights, at $0.35 in and $0.75 out per million. The public shared catalog is thin, just GPT-OSS 120B and Gemma 4 31B as of August 2026. More model families live on dedicated endpoints and through partners like OpenRouter, Hugging Face, Vercel and AWS Marketplace.

### Parasail

Parasail calls itself the inference cloud for AI-native startups. Instead of owning data centers, it aggregates GPUs from many hardware providers and sells them through one OpenAI-compatible API. Customers choose serverless per-token endpoints, Elastic Endpoints that scale with traffic and bill only for tokens used, dedicated deployments with negotiated latency SLAs, or batch. Its commit-to-spend model lets one commitment draw down across any model or hardware.

## Which is best, and when

### Choose Cerebras for

- Workloads where generation time is the user's wait

### Choose Parasail for

- Batch on any Hugging Face model, including private ones
- Evals and embeddings at per-parameter rates
- Startups shifting traffic from closed APIs under ZDR terms
