Want to model Mithril/ML Foundry cluster cost? Calculate H100, H200, B200 & GB200 NVL72 TCO with the ClusterMAX calculator.

Mithril (formerly ML Foundry, formerly Foundry) operates as a GPU aggregator, or what they term an “AI omnicloud.” Their core philosophy is that the primary problem in the GPU market is one of price discovery and market inefficiency. Their solution is to create a “fluid market” through aggregation and abstraction, allowing costs to adjust dynamically to reflect increased supply. We completely disagree with both the premise and solution.

The premise that the GPU market lacks price discover is flawed and represents a fundamental misunderstanding of the market. In our experience, over 90% of the GPU cloud rental volume is done on long-term contract between enterprises with a standard 25% down and monthly payments through the end of the term. In other words, a typical B2B transaction.

The reason for this, which has been detailed throughout this report, is that not all GPUs are deployed equally. GPU compute is not a commodity. Mithril, and other companies trying to aggressively financialize the GPU market as though it is crude oil or lumber, is solving for price per GPU-hr as the only variable. This is an important criteria, but it is just one the 129 criteria that we use to assess a provider’s quality, and is often a poor proxy for the realized TCO of a cluster.

By building abstractions on top of an aggregated and abstracted “roll-of-the-dice” marketplace of underlying providers, Mithril places the entire operational burden on the end user. As a provider, Mithril has no control over their customer’s support experience, orchestration software preferences, networking and storage performance, monitoring experience, or, most critically, the reliability and security posture of the cluster.

With that said, even if GPU compute was a liquid, commoditized market, we would expect the winner to have open access to many GPU providers, real-time data feeds on availability, forecasts for upcoming supply, proxy information for realized quality from end users… but unfortunately we are left with this instead:

Mithril/ML Foundry GPU Cloud FAQ

What tier is Mithril/ML Foundry in ClusterMAX?

Mithril/ML Foundry is rated Underperforming tier in the ClusterMAX 2.0 GPU cloud rating system by SemiAnalysis (with the ClusterMAX 2.1 Update applied April 2026). Underperforming is flagged by ClusterMAX as underperforming — capable of reaching Bronze or Silver if critical gaps are fixed. Can rise to Bronze or Silver quickly if critical issues are fixed (security attestation, modern GPUs, etc.).

Is Mithril/ML Foundry SOC 2 Type II certified?

Mithril/ML Foundry's ClusterMAX review does not flag a SOC 2 Type II attestation as confirmed. SemiAnalysis treats SOC 2 Type II as a baseline expectation for any GPU cloud serving enterprise or regulated AI workloads — see the ClusterMAX criteria page for the full security baseline.

Does Mithril/ML Foundry support Slurm?

Mithril/ML Foundry's ClusterMAX review does not call out a first-party managed Slurm offering. Customers wanting Slurm-on-Kubernetes (SUNK, Soperator, Slinky) should compare Mithril/ML Foundry against providers that explicitly list managed Slurm in their offering — see the ClusterMAX /slurm expectations page for the full bar.

Does Mithril/ML Foundry support Kubernetes?

Mithril/ML Foundry's ClusterMAX review does not document a first-party managed Kubernetes service. See the ClusterMAX /k8s expectations page for the managed-Kubernetes bar SemiAnalysis tests against when evaluating GPU cloud providers.

What GPUs does Mithril/ML Foundry offer?

The Mithril/ML Foundry ClusterMAX review covers their current GPU inventory and on-demand availability. SemiAnalysis tracks H100, H200, B200, GB200 NVL72, GB300 NVL72, and MI300X / MI355X availability across all 85 providers in the ClusterMAX 2.0 + 2.1 cohort.

What is the NCCL all-reduce performance on Mithril/ML Foundry?

Mithril/ML Foundry's ClusterMAX review does not yet publish hands-on NCCL all-reduce results. NCCL all-reduce bandwidth is the standard SemiAnalysis benchmark for InfiniBand / RoCE health on GPU clusters — see the ClusterMAX /health-checks page for the full benchmark methodology.

How does Mithril/ML Foundry compare to CoreWeave?

CoreWeave is the only ClusterMAX Platinum provider, while Mithril/ML Foundry is rated Underperforming. The Mithril/ML Foundry review documents the specific gaps versus CoreWeave across the 10 ClusterMAX criteria (Security, Lifecycle, Orchestration, Storage, Networking, Reliability, Monitoring, Pricing, Partnerships, Availability). See the Mithril/ML Foundry review body and the ClusterMAX /criteria page for the full comparison framework.

Is Mithril/ML Foundry recommended for LLM training?

Mithril/ML Foundry's current ClusterMAX rating (Underperforming) means SemiAnalysis does not directly recommend Mithril/ML Foundry for production LLM training without first addressing the specific gaps called out in the review. See the Mithril/ML Foundry review for the gating issues and see the ClusterMAX /cloudreview index for currently recommended alternatives in Platinum / Gold / Silver / Bronze.
