## Code Arena

Code Arena is built for developers who want evidence rather than marketing claims when choosing a coding model. Instead of reading benchmark tables, you prompt multiple frontier models with the same request, watch them construct web apps and sites in real time, and then judge the output on accuracy, logic, and code quality. The 'battle' format mirrors the popular blind-comparison leaderboard approach, adapted specifically for software generation tasks.

The platform is designed to handle multi-file projects rather than single snippets, so the comparisons reflect the messy reality of real development work: routing, component structure, styling, and state management all have to hold together. Results are surfaced through a leaderboard so you can see which models are consistently favoured by the community over time.

Because the tool is free to use and browser-based, it works well as a quick sanity check before committing a paid subscription or API budget to a particular model, and as a way to keep a finger on the pulse of how fast the coding-model landscape is moving.

**Pricing & Plans:** Free to use; no paid tier is advertised on the product page. Related enterprise/API offerings from Arena may be priced separately.

- **Model battles:** Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
- **Real-time app building:** Watch models construct web apps and websites live, so you can see process and output, not just the final file.
- **Multi-file generation:** Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
- **Community leaderboard:** Track which coding models accumulate the most wins over time to identify consistently strong performers.
- **Free browser access:** Run comparisons directly in the browser without installing anything or paying for credits.

**Strengths:** Free, no-signup barrier for quick comparisons; Tests full multi-file projects, not just isolated snippets; Live battles reveal model behaviour, speed, and failure modes; Leaderboard aggregates community signal over time

**Limitations:** Battles are subjective and depend on the prompts you write; Not a full IDE replacement for day-to-day development; Leaderboard results can shift quickly as new models ship

## Nebius

Nebius positions itself as "the ultimate AI cloud," an infrastructure stack engineered specifically for AI workloads rather than adapted from general-purpose cloud. The core of the platform is raw GPU capacity from NVIDIA — including GB300 NVL72, HGX B300, GB200 NVL72, HGX B200, H200, H100, RTX PRO 6000, and L40S — delivered as non-virtualized instances attached to InfiniBand networking. Above that sit managed services such as Kubernetes, Soperator (Slurm on Kubernetes), PostgreSQL, and MLflow, so teams get the orchestration and experimentation tooling that large training runs need without assembling it themselves.

On the inference side, Nebius offers Token Factory, a managed endpoint for running open and frontier models, alongside serverless compute options. Storage is available as shared filesystems, WEKA, block volumes, and tiered object storage, all priced transparently by the gigabyte. Consumption is flexible: customers can pay on-demand, use preemptible and spot capacity at market-driven prices, or reserve capacity through commitments for lower rates. Networking egress, public IPs, and Kubernetes management are listed as free, which simplifies capacity planning.

Nebius supports the full lifecycle — pre-training, post-training, and inference — and publishes customer stories spanning financial services, healthcare, robotics, media, and e-commerce. Because the company also operates its own data centers and hardware supply chain, it can offer capacity guarantees and support arrangements that are hard to match on repurposed public cloud. Pricing is usage-based and published on the site, with contact needed for large clusters and enterprise agreements.

**Pricing & Plans:** Usage-based pricing published on the site. On-demand GPU instances range from roughly $1.55/GPU-hour for L40S up to about $9.50/GPU-hour for HGX B300, with preemptible and live spot options starting around $0.79/GPU-hour. CPU-only instances start near $0.06/cpu-hour, managed Kubernetes and networking are free, and large-scale clusters or commitments are quoted through sales.

- **Non-virtualized GPU clusters:** Bare-metal access to NVIDIA GB300, B300, GB200, B200, H200, H100, RTX PRO 6000, and L40S GPUs connected over InfiniBand for training and inference at scale.
- **Nebius Token Factory:** A managed inference service for running popular open and frontier models through an API, so applications can add LLM capabilities without owning GPUs.
- **Managed MLOps services:** Built-in Kubernetes, Soperator for Slurm jobs, PostgreSQL, and MLflow give teams a ready-made environment for orchestration, tracking, and experiments.
- **Flexible consumption and spot pricing:** Choose on-demand, preemptible, or live market-driven spot capacity, or commit to reserved clusters for discounts on long-running workloads.
- **Scalable AI storage:** Shared filesystems, WEKA, block volumes, and tiered object storage sized for multi-hundred-terabyte training datasets.

**Strengths:** Transparent, publicly listed per-hour GPU and storage pricing; Broad NVIDIA lineup from L40S up to GB300 NVL72; Free Kubernetes management, networking egress, and public IPs; Integrated MLOps tooling including MLflow, Slurm via Soperator, and PostgreSQL

**Limitations:** Top-end clusters like GB300 and GB200 are quote-only, not self-serve; Spot and preemptible capacity is interruptible and prices move with demand; Requires meaningful ML infrastructure knowledge to get the most out of it
