## GPUPerHour

GPUPerHour solves a narrow but expensive problem: cloud GPU pricing is scattered across dozens of provider dashboards, in different units and with different availability. The site periodically scrapes the public pricing and inventory endpoints of 31 cloud GPU providers, normalises each listing to a price per GPU per hour (dividing a multi-GPU instance price by its GPU count) and tags it with its pricing type and security tier. The current-price summary deliberately uses only secure on-demand offers observed within roughly 15 minutes of the last refresh, excluding spot, reserved and peer-to-peer marketplace listings because those prices are not directly comparable.

The result is a single live table covering H100 SXM5 and PCIe, H200, B200, B300, A100 80GB and 40GB, L40S, RTX PRO 6000, RTX 5090, RTX 4090 and RTX A6000, alongside the provider, a 30-day historical catalog average and the number of providers with stock. A daily price index with CSV downloads lets you track how pricing moves over time, while buying guides and hardware explainers cover practical topics such as comparing like-for-like GPUs, choosing by VRAM for a workload, accounting for storage and egress, and renting by the hour. The site also points to a companion console, DeployGPU, for provisioning on supported providers from one place.

The key caveat is stated openly on the page: offer counts describe configurations, not the number of physical GPUs bookable, and availability can change before you complete a booking. Prices are per GPU-hour but providers bill for the whole instance, and storage, network transfer and commitment terms affect the final bill. GPUPerHour is a research and comparison layer, not a hosting provider itself.

**Pricing & Plans:** Free to use as a price-comparison and research resource; GPUPerHour does not sell GPU capacity itself. The prices shown are third-party provider rates for secure on-demand instances, per GPU-hour, and a companion service (DeployGPU) offers deployment on supported providers.

- **31-provider live price table:** Every tracked offer is normalised to a price per GPU-hour and shown with its provider, pricing type and security tier.
- **Cheapest-offer summary:** A market snapshot highlights the lowest current secure on-demand price for each popular GPU model, from H100 and H200 to RTX 4090.
- **Daily price index and CSV:** Historical catalog averages and downloadable daily data let you see how pricing for a given GPU has moved over the last 30 days.
- **Buying guides and explainers:** Practical articles cover comparing like-for-like GPUs, choosing by VRAM, estimating the full bill with storage and egress, and renting by the hour.
- **DeployGPU console:** A linked console lets you deploy on supported providers from a single place once you have picked an offer.

**Strengths:** Aggregates 31 providers into comparable per-GPU-hour prices; Clearly states its methodology and excludes non-comparable spot and P2P listings; Free to use, with daily historical data and CSV downloads; Buying guides cover the full bill, not just the headline rate

**Limitations:** Only covers providers whose pricing and inventory endpoints are publicly scrapable; The current-price view deliberately excludes spot and reserved capacity, which are often cheaper; It is a comparison resource, so you still create accounts and provision instances with the provider itself

## Weights & Biases (CoreWeave Forge)

Weights & Biases (W&B) has long been the go-to toolkit for machine learning teams that need to see what their models are doing. Following its integration into CoreWeave, the platform now operates as CoreWeave Forge while keeping the same core capabilities — and, importantly, existing W&B credentials continue to work, so current users can sign in and access their projects and data as before.

The platform spans the full AI development loop. During training you log metrics, losses, and sample media and compare hundreds of runs in interactive dashboards. You can launch automated hyperparameter sweeps, version datasets and model artifacts, and manage promotion through a model registry. For generative AI work, the same environment provides prompt logging and evaluation plus tracing for LLM applications, covering the LLMOps side of the workflow.

Because it is now part of CoreWeave Forge, W&B sits in a broader connected environment that also covers compute and serving, letting teams run models and agents without stitching together separate tools. It is widely used across research, ML engineering, and applied AI teams, from solo practitioners on the free tier to enterprise organizations with governance and scale requirements.

**Pricing & Plans:** Freemium. There is a free tier for individuals and small teams, with paid team and enterprise plans that add collaboration, governance, and higher usage limits. Exact enterprise pricing is provided on request; the platform is also offered as part of the broader CoreWeave Forge environment.

- **Experiment tracking and visualization:** Log metrics, losses, and media from training runs and compare them side by side in interactive charts to spot what actually improves your model.
- **Hyperparameter optimization:** Run automated hyperparameter sweeps and visualize parameter importance so you can converge on better configurations faster.
- **Artifacts and model registry:** Version datasets and model artifacts, track lineage, and promote models through a registry from training to production.
- **LLM and prompt evaluation:** Build, log, and evaluate LLM prompts and applications, with tracing and evaluation tools grouped under an LLMOps workflow.
- **AI apps and agents:** Ship AI applications and agents in one connected environment that spans tracking, serving, and cloud infrastructure.
- **Team collaboration and reports:** Share runs, dashboards, and reports with teammates so results and findings stay reproducible across the team.

**Strengths:** Mature, widely adopted experiment tracking with rich interactive visualizations; Covers the full lifecycle: tracking, sweeps, artifacts, registry, and LLM evaluation; Now backed by CoreWeave infrastructure as part of CoreWeave Forge; Strong framework and library integrations, so setup takes only a few lines of code

**Limitations:** The platform has been rebranded under CoreWeave Forge, which may confuse users looking for the classic Weights & Biases name; Large-model training and inference features are tied into the broader CoreWeave cloud offering; Free tier has usage and storage limits that growth teams will outgrow; Enterprise pricing requires contacting sales, so budgeting needs a conversation
