Every model, one endpoint
Browse 40+ open and frontier models on Parasail's inference cloud. Filter by category, compare specs, and call any model with one OpenAI-compatible API.
Get performance tuned to your needs
Strike your own balance of speed, quality, and cost and an optimization agent tunes your deployment to hit it. Lossless by default, with no hidden quantization. Any lossy speedup is yours to opt into.
Commit to spend, not GPUs
Elastic endpoints support selected models, with more added individually. Contact sales to set up an endpoint or discuss custom models and configurations.
Capacity that follows demand
Elastic endpoints give eligible models dedicated GPU performance, billed per token — no GPU-hour commitment or idle-GPU bill. One pricing tier: 25% above the model’s Serverless input and output token rates.
Fixed capacity means guessing
Forecast high and you're paying for GPUs sitting idle. Forecast low and you're throttling requests right when demand peaks. Either way, you're locked into a number that rarely matches reality.
One API for any model
One endpoint, any model — frontier open models and your own fine-tunes, day zero.

Kimi K3 vs. GPT-5.6 Sol: Performance, cost, and tradeoffs
Compare Kimi K3 and GPT-5.6 Sol on performance, pricing, context, weights, architecture, and deployment tradeoffs.
How Parasail built one AI agent for inference operations
The hard part wasn’t putting an AI agent in Slack. It was embedding trusted sources, reviewed calculations, and safe inference-operations workflows.
Building sub-second LLM inference for global AI traffic
A fast model isn’t a fast API. We worked backward from a 600ms p99 budget with Cloudflare Workers at the edge and WireGuard to the GPU.
Your questions, answered.
We're paying a closed-model vendor directly. Can we switch?
Yes — one of the most common reasons teams come to us. Parasail runs open-source models on dedicated infrastructure without single-vendor dependency. Capacity and rate limits depend on your endpoint. Most teams run Parasail alongside their existing setup first, then migrate workloads over.
Are the models as capable as Claude or GPT for my use case?
For most production use cases, yes — and for some, better. The best open models (Llama, DeepSeek, Qwen, Kimi) have closed the gap, and for domain-specific tasks a well-tuned open model often outperforms a general closed one. For sales-assisted deployments, our team can help evaluate models against your workload.
Can I use specialized or fine-tuned models?
Yes — contact our team for specialized or fine-tuned models, custom architectures, and sidecar containers. Elastic endpoints support selected models, with additional models rolling out individually. Contact sales to set up an endpoint and discuss availability for your workload.
If something breaks, can I talk to a person who'll fix it?
Yes — you can contact our team for help. If you need dedicated support or specific service guarantees, talk to us about your deployment requirements.
How fast can we get up and running?
Contact sales to set up an Elastic endpoint. We support selected models, with more added individually; our team will confirm model availability and setup details for your workload. Contact us to discuss custom models and configurations, too.
Why not just self-host?
Self-hosting looks cheaper until you account for MLOps headcount (two to three engineers), idle GPU burn, scaling complexity, and constant maintenance as models evolve. Elastic endpoints provide dedicated GPU performance for eligible models without managing infrastructure or making a GPU-hour commitment. Contact sales to set up an endpoint or discuss custom models and configurations.
