## 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

## Width.ai

Width.ai positions itself as a hands-on AI and machine learning consultancy rather than a SaaS vendor. Founded around work with early GPT-3 APIs in 2021, the team has shipped natural language processing, computer vision, chatbot and document-extraction projects for startups, service businesses and enterprise clients. Its stated philosophy is pragmatic delivery: "no powerpoints, we just ship" — meaning engagements are typically measured by working software, dashboards and automation pipelines rather than strategy decks.

The company organizes its work around three engagement patterns. The first is automating internal business operations, where it builds backend automations and agentic workflows for service companies that want to cut manual effort; the firm says more than 50 services companies have used these systems. The second is end-to-end product development, taking AI products from concept or MVP through to launch, with several clients reportedly raising seven- and eight-figure rounds on the back of work developed with Width.ai. The third is coaching and advisory: helping non-AI development teams and executives understand what is actually buildable and where the market is heading.

Publicly documented case studies include a state-of-the-art GPT-based summarizer that handles long and short documents in multiple formats (news articles, blog posts, legal documents), GPT-3 topic extraction for asset-management interviews, and analytics dashboards for media and influencer businesses — one client reported a 36% lift in advertiser revenue within a month of launch. The company also maintains technical writing and a related data-visualization product, Pumice.ai. Pricing is quoted per project, so teams should expect a scoping call rather than a public price sheet.

**Pricing & Plans:** Custom, contact-based pricing. Width.ai does not publish rates; engagements are scoped per project after a discovery conversation. Its /pricing page is password-protected, so quotes come from the team directly.

- **Custom LLM and GPT development:** Design and build of production generative AI features — summarization, topic extraction, extraction and classification — on top of modern large language models.
- **Computer vision and document extraction:** Image recognition, object detection and document parsing pipelines that convert unstructured files and visual data into structured, usable records.
- **AI chatbots:** Conversational assistants wired into a company's own tools and data so they answer with business context instead of generic model output.
- **Business process automation:** Backend automations and agentic systems that remove repetitive manual work for service companies and plug into existing software stacks.
- **Advisory and team coaching:** Working sessions and guidance for engineering and leadership teams who need to evaluate vendors, pick the right architecture or get current on what is buildable.

**Strengths:** Deep, hands-on experience with LLMs tracing back to 2021, with public case studies and technical writing to back it up; Covers the full stack of AI work — NLP, computer vision, chatbots, automation and advisory — instead of a single narrow niche; Delivery-oriented posture: engagements are framed around shipped software rather than strategy documents; Strong reference base, including testimonials from CEOs, professors and other consultancy clients

**Limitations:** No public pricing and a password-protected pricing page, so budgeting requires a sales conversation first; It is a consultancy, not a self-serve tool — there is no free trial or instant sign-up; Project timelines and outcomes depend heavily on client-side access to data, systems and decision-makers; Public materials lean on case studies and testimonials rather than standardized benchmarks
