## 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

## Relyable

Relyable was built by a team that develops voice agents and treats testing as a first-class part of shipping them. Rather than rely on human spot-checks, it uses AI to create personas and scenarios that mimic real callers — old and angry, young and confident, different accents, moods and goals — and then runs those conversations in parallel against your deployed agent. Each call is analysed automatically, so problems surface before a single real customer encounters them.

Evaluation is driven by a rubric you control. You can weight criteria such as end-to-end task completion, freedom from fabricated policy or pricing, stable customer sentiment, clean interruption handling, latency under a p95 target and appropriate out-of-scope handoff. Relyable tracks pass rates and seven-day trends for each criterion, giving a quantified picture of whether a change helped or hurt.

In production, the platform becomes a monitoring layer. Live calls are logged and scored in real time, and Relyable pages you only when a threshold is crossed — through Slack, email, PagerDuty, Opsgenie, Linear or a webhook. The company is headquartered in Melbourne, Australia, and is associated with NVIDIA Inception, ElevenLabs Grants and Microsoft for Startups.

**Pricing & Plans:** Relyable uses credit-based pricing where credits cover both simulated and live calls. Core is $500/month with 50,000 credits (up to 750 simulated calls and 10,000 live evaluations), and Premium is $1,000/month with 125,000 credits (up to 1,900 simulated calls and 25,000 live evaluations). Annual billing saves about 15%. Enterprise offers custom credit packages, regional compliance and dedicated support.

- **Automated conversation simulation:** Auto-generate test cases from your system prompt or define your own, then run hundreds of parallel simulated conversations with presets for accent, mood and goal.
- **Rubric-based evaluation:** Score every call against weighted, customisable criteria such as task completion, policy accuracy, sentiment, interruption handling and latency, with seven-day trend tracking.
- **Live production monitoring:** Every production call is silently logged and scored in real time, with alerts routed to Slack, email, PagerDuty, Opsgenie, Linear or webhooks when something drifts.
- **No-code platform integrations:** Connect Vapi, Retell or ElevenLabs agents in under five minutes using an API key, or route custom agents through the provided number and API.
- **Industry playbooks:** Hardware and industry templates for financial services, home services and real estate, including compliance, emergency-pathway and booking scenarios.

**Strengths:** Combines simulation, rubric-based evaluation and live monitoring in one platform.; Fast native integrations with Vapi, Retell and ElevenLabs using just an API key.; Rubric weighting and seven-day trend tracking turn voice agent quality into measurable numbers.; Alert routing to Slack, PagerDuty, Linear and webhooks fits existing on-call workflows.

**Limitations:** Pricing starts at $500/month, so it is a significant commitment for very small teams.; Native integrations currently center on Vapi, Retell and ElevenLabs; other platforms require the manual prompt-upload and call-routing workaround.; Evaluation quality still depends on how well you define your rubric and test cases.; Because it targets production voice agents, it is less relevant if you are only experimenting.
