## FluidStack

FluidStack is an AI compute provider that builds the physical layer underneath frontier model work: data centers, power, cooling and very large GPU clusters. Its public positioning is deliberately infrastructural rather than product-led — it describes building gigawatt-scale compute, bringing new sites online in months, and operating tens of millions of accelerators reliably. For teams training or serving large models, that translates into reserved, single-tenant-class capacity that is provisioned and operated for you rather than an instant, self-serve VM catalogue.

A distinguishing theme is the pairing of power and compute. FluidStack writes about redesigning compute and power infrastructure from first principles, developing off-grid solar to supply clusters, and using closed-loop cooling that fills tanks once and recirculates water indefinitely. It also emphasises building in the United States with onshored manufacturing, framing infrastructure ownership as a strategic question about which values shape the technology being built. For AI organisations, these are increasingly relevant because energy availability, not chip supply alone, is the binding constraint on scaling.

If you need a small number of GPUs for a day, FluidStack is probably not the fastest route; capacity is engaged at enterprise scale through a sales process. If you are planning a multi-month training run or a production inference fleet and want dedicated, purpose-built infrastructure with managed operations, it is a strong candidate to evaluate alongside the major hyperscalers and specialised GPU clouds.

**Pricing & Plans:** Enterprise and contact-for-pricing. FluidStack does not publish per-GPU-hour rates or a self-serve sign-up on its website; capacity is scoped and quoted through a direct sales conversation based on cluster size, duration and hardware. Catalogue listings classify it as a paid product requiring contact for pricing.

- **Datacenter-scale compute built in-house:** FluidStack designs and builds large AI data centers, including high-density campuses with significant per-site power capacity, rather than reselling capacity from other clouds.
- **GPU clusters for training and inference:** Clusters are architected for large-scale model training and inference, with high-bandwidth interconnect and orchestration suitable for distributed workloads.
- **Power and cooling engineered together:** The company develops off-grid solar and recirculating closed-loop cooling, treating power and water efficiency as core engineering problems.
- **Managed operations and reliability:** Smart hands, cluster provisioning and operations support let research teams focus on models while FluidStack runs the physical and orchestration layers.
- **US-built and onshored supply chain:** Data centers are built in the United States with onshored manufacturing of compute and power infrastructure, a deliberate supply-chain and sovereignty choice.

**Strengths:** Purpose-built AI infrastructure rather than generic cloud resale; Power, cooling and data center design handled in-house, which matters at scale; Managed provisioning and operations for large training and inference clusters; Explicit positioning on US-built, onshored infrastructure

**Limitations:** No published self-serve pricing or instant sign-up; access requires a sales conversation; Enterprise-scale focus means very small individual workloads may not be a fit; Capacity is concentrated in US locations, which may matter for latency-sensitive or data-residency-bound teams

## Leonardo.Ai

Leonardo.Ai started as a prompt-to-image generator and grew into a full creative production platform. Users describe what they want in text, then steer the output with controls such as negative prompts, image-to-image, canvas inpainting and outpainting, and reference images. The platform hosts a rotating set of its own models (including the Phoenix and Lucid lines) alongside a marketplace of community-trained models that target specific styles, from photorealism to game concept art.

A distinguishing feature is custom model training: you can upload a small set of images and train a private model that reproduces your character, product, or art direction consistently across every generation. This makes the tool practical for studios building game assets, marketing teams producing campaign visuals, and illustrators developing concept art, rather than only for one-off experiments.

Beyond still images, Leonardo.Ai offers motion and video generation plus texture tools used in 3D and game workflows. It runs entirely in the browser, offers an API for programmatic generation, and provides collaborative workspaces for teams. It joined Canva in 2024, which broadened its integration into a wider design ecosystem.

**Pricing & Plans:** Freemium. A free tier provides a limited daily allowance of generation tokens; paid subscription tiers scale token allowances, faster processing, private generations, and higher commercial usage. API access is billed separately by usage.

- **Fine-grained image generation controls:** Use negative prompts, guidance strength, style references, and image-to-image to push generations toward a precise result instead of relying on luck.
- **Custom model training:** Train a private model on your own reference images to keep characters, products, and art styles consistent across every asset you produce.
- **Canvas editing and outpainting:** Extend or refill parts of an image directly on the canvas to fix errors, change framing, or build wider scenes without leaving the platform.
- **Community model library:** Browse and apply thousands of community-trained models tuned for niches such as anime, photography, illustration, and game art.
- **Video, motion, and texture generation:** Animate stills, create short video clips, and generate 3D textures for game and product pipelines.

**Strengths:** Strong control options compared with many single-prompt generators; Custom model training makes long projects visually consistent; Large community model library covers many niche styles; Free tier lets you evaluate quality before paying

**Limitations:** Token limits on lower tiers can be consumed quickly at high resolution; Interface has many parameters, giving newcomers a learning curve; Occasional style or anatomy artifacts require re-rolling or editing
