## How they compare

Parasail's own description of its customers reads like an OpenAI migration plan. Most start by running Parasail alongside a closed-model vendor, then shift workloads over under a standard zero data retention and SLA agreement, and its OpenAI-compatible API makes that incremental. The cost argument is batch: any Hugging Face model, private repos included, at half of serverless pricing, with cached tokens another 50% off. A 4B to 8B model runs $0.03 in and $0.06 out per million at FP4. OpenAI's Batch halves prices too, but its cheapest tier, Luna, lists at $0.20 in before that discount.

The limits are capability and consistency. Parasail serves open models on GPUs it aggregates from many hardware providers, so performance depends on those providers, and reserved GPU pricing is quote-only. OpenAI serves its own closed GPT models with a 1.05M window, hosted tools and the Agents SDK. Parasail designed its real-time path around a 600ms p99 budget, and its commit-to-spend model lets one commitment draw down across any model or hardware. For evals, embeddings and offline data processing, Parasail is the cheaper fit.

## What each one does

### OpenAI

OpenAI runs the most widely adopted closed-model API. Its September 2026 lineup has GPT-6 Astra at the top for computer use, coding and long agentic runs, priced at $10 in and $50 out per million tokens. Below it sits the GPT-5.6 family: Sol for hard professional work, Terra as the balanced default, and Luna for high-volume jobs at $0.20 in and $1.20 out. All of them carry a 1.05M token context window with up to 128K output.

### 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 OpenAI for

- Tasks where only closed frontier quality will do
- Multi-tool agents with hosted search and code execution
- Teams that want one vendor for everything

### Choose Parasail for

- Evals, embeddings and offline data processing at batch rates
- Gradually moving narrow workloads off a closed API
- Running private Hugging Face models with flexible commitments
