Quick Overview

One-line Description: Deploy and scale machine learning models on serverless GPUs with ultra-low cold starts.

What it does: Inferless provides a serverless GPU inference platform that allows developers and businesses to effortlessly deploy and scale machine learning (ML) models. It focuses on significantly reducing cold start times and simplifying infrastructure management, enabling users to pay only for the GPU resources they consume. The platform offers features like automated scaling, custom runtimes, and continuous integration/continuous deployment (CI/CD) to streamline the ML model deployment process.

Best for: Developers, data scientists, startups, and technology companies seeking to deploy ML models quickly, cost-efficiently, and at scale without the complexities of managing traditional GPU infrastructure. It is particularly well-suited for applications with "spiky and unpredictable workloads" and those requiring low latency.

Key Features

• Effortless Deployment: Deploy machine learning models in minutes using a web-based UI, CLI, or remote execution capabilities, supporting models from Hugging Face, Git, Docker, AWS S3, and Google Cloud Buckets.
• Dynamic Autoscaling: Automatically scales from zero to hundreds of GPUs based on demand, handling unpredictable workloads efficiently with an in-house load balancer to minimize overhead and avoid idle costs.
• Lightning-Fast Cold Starts: Optimizes model loading to achieve sub-second response times, even for large models, by using high IOPS storage close to GPUs, drastically reducing typical cold start latencies.
• Custom Runtimes: Allows users to customize the container environment with specific software and dependencies required for their models.
• Persistent Volumes: Provides NFS-like writable volumes that support simultaneous connections to various model replicas for data management.
• Automated CI/CD: Enables automatic rebuilding and redeployment of models upon repository updates, eliminating the need for manual re-imports and ensuring the latest model versions are always in use.
• Advanced Monitoring: Offers detailed call and build logs, along with real-time metrics (total calls, cold start times, GPU usage), to monitor and refine models efficiently.
• Dynamic Batching: Increases throughput by combining multiple server-side requests, optimizing GPU utilization and performance under varying loads.
• Private Endpoints: Allows customization of endpoint settings such as scale-down, timeout, and concurrency, offering fine-grained control over model deployment.

Pricing Structure

Free Plan:

• $30 Free Credit to start.
• Free 50GB/month storage.
• Pay-per-second usage for GPU inference.

Paid Plans: Inferless primarily operates on a pay-as-you-go model, where costs are determined by the GPU type and duration of use. There isn't a fixed monthly subscription in the traditional sense, but features scale with usage.

• Usage-Based Billing: Charged per second for GPU resources consumed, with different rates for various NVIDIA GPU types (T4, A10, A100).
• Volume Pricing: Additional storage beyond 50GB/month is charged at $0.3/GB/month.

Enterprise: Contact for custom pricing and advanced features. Features typically include higher GPU concurrency (e.g., up to 50), longer log retention (365 days), and dedicated support via private Slack connect and a support engineer.

Free Trial: $30 free credit to test the platform.

Money-back Guarantee: Fees are generally non-cancelable and non-refundable, except if Inferless breaches its obligations under the agreement, in which case a prorated refund of prepaid fees may be available upon user account termination.

Pricing Plans Explained

Free Tier (with $30 Credit)

What you get: Access to the Inferless platform to deploy machine learning models using serverless GPUs. You receive an initial $30 credit to cover your usage costs and 50GB of free storage per month.

Perfect for: Individuals, students, researchers, and small teams looking to experiment with serverless ML deployment, test model performance, and evaluate the platform's capabilities without an upfront financial commitment.

Limitations: Usage is limited by the $30 credit and 50GB storage. Once credits are consumed, regular pay-as-you-go rates apply. Support is likely community-based or through general channels.

Technical terms explained:

• Serverless GPU: This means you don't need to set up or manage physical or virtual GPU servers. Inferless handles all the underlying infrastructure, allowing you to deploy your models without worrying about provisioning hardware or maintaining it. You only pay for the computational power (GPU usage) when your models are actively processing requests.
• Cold Start: This refers to the delay experienced when a machine learning model, particularly a large one, is first loaded and initialized to serve a request after a period of inactivity. Inferless significantly reduces this delay, ensuring faster response times.

Usage-Based (Standard Pay-as-you-go)

What you get: Full access to Inferless's serverless GPU inference platform, where you pay per second for the GPU resources your models consume. You can choose from various NVIDIA GPU types (T4, A10, A100) with different specifications and corresponding per-second/per-hour rates. Storage beyond 50GB/month is also billed. This tier provides unlimited deployed webhook endpoints, GPU concurrency (e.g., up to 5-10 max replicas, depending on resource availability), and 15 days of log retention.

Perfect for: Fast-growing startups, independent developers, and small to medium businesses needing flexible, scalable, and cost-efficient ML model deployment for production workloads. It's ideal for those with fluctuating demand who want to avoid fixed infrastructure costs.

Key upgrades from free: Continuous usage beyond the initial $30 credit, access to a wider range of GPU types for more demanding models, and features suitable for production environments. Support may include private Slack connect within 48 working hours.

Technical terms explained:

• GPU RAM: Graphics Processing Unit Random Access Memory. This is the memory available directly to the GPU for processing data. More GPU RAM allows for larger and more complex models to run efficiently.
• vCPUs: Virtual Central Processing Units. These are the virtualized processing cores that support the GPU and handle general computing tasks, such as data pre-processing and post-processing, alongside the GPU's specialized tasks.
• RAM: Random Access Memory. This is the main system memory available to the instance running your model, separate from GPU RAM.
• Concurrency: This refers to the number of requests or model instances that can be processed simultaneously. Higher concurrency means the platform can handle more incoming requests at the same time.
• Log Retention: The period for which your operational logs (call logs, build logs) are stored by Inferless, allowing for debugging and performance analysis.

Enterprise Plan

What you get: All features of the usage-based tier, with enhanced capabilities tailored for large organizations. This typically includes much higher GPU concurrency (e.g., up to 50 max replicas), extended log retention (365 days), and dedicated premium support through a private Slack connect channel and a dedicated support engineer. Pricing is custom and usually involves direct contact for a quote.

Perfect for: Large enterprises, organizations with very high-volume, mission-critical AI applications, or those with specific compliance, security, and support requirements.

Key upgrades: Significantly higher scaling limits, extended data retention for compliance and in-depth analysis, and personalized, rapid-response customer support.

Technical terms explained:

• GPU Concurrency (Enterprise): For enterprise-level needs, Inferless offers even greater flexibility, allowing for a higher number of simultaneous model instances or requests (e.g., up to 50 replicas) to handle massive inference loads.
• Dedicated Support Engineer: A specialized support professional assigned to your account to provide personalized assistance, troubleshooting, and optimization guidance, ensuring smooth operations for critical workloads.
