## Modal

Modal provides cloud infrastructure aimed squarely at AI and data teams. The core idea is that developers write ordinary Python, decorate functions or define container images, and Modal takes care of the underlying compute: scheduling containers, attaching GPUs, autoscaling from zero and back, and exposing endpoints over HTTPS. Infrastructure concerns like networking, storage, and capacity management are abstracted away, so a workload that runs on a laptop can run the same way across a fleet.

The platform is organised around a few primitives. Functions handle serverless compute and can fan out across thousands of GPUs for parallel or batch work. Sandboxes provide isolated environments for coding agents, reinforcement learning rollouts, and other untrusted code, with sub-second start times and support for very high concurrency. Training covers fine-tuning, reinforcement learning, and evaluation on single or multi-node GPU capacity. On the inference side, Modal offers OpenAI-compatible endpoints for open-weight models and lets teams deploy custom stacks and tune endpoints to match their traffic shape.

Underneath, Modal runs its own container runtime and image system designed for large images and fast GPU scheduling, along with a distributed filesystem for fast access to model weights and datasets. Capacity is drawn from a multi-cloud pool spanning many regions, with automatic routing to available hardware and continuous fleet health checks. Billing is usage-based, charged by the second while code runs, with granular cost controls. The company offers a free starting allowance and scalable paid usage, and markets to enterprises with SOC 2 Type II compliance and HIPAA readiness.

**Pricing & Plans:** Modal uses usage-based pricing billed by the second: a free monthly compute allowance gets you started, then you pay for the CPU, memory, and GPU resources your workloads consume. Enterprise plans and startup credits are available, and custom pricing can be discussed with sales.

- **Serverless Python functions:** Write plain Python, attach GPUs or containers, and deploy HTTPS endpoints that autoscale with traffic and scale to zero when idle.
- **Sandboxes for agents:** Launch isolated, secure environments for coding agents, RL rollouts, and untrusted code, with sub-second starts and support for over a million concurrent sandboxes.
- **Training and fine-tuning on demand:** Run fine-tunes, LoRA, full training, and reinforcement learning on elastic single or multi-node GPU capacity with no quota requests.
- **Model inference and endpoints:** Serve LLMs and image, video, or audio models through OpenAI-compatible endpoints, or bring your own inference stack and let Modal handle the infrastructure.
- **Fast storage and multi-cloud capacity:** A distributed filesystem loads large images and model weights at full bandwidth, while a pool spanning 20+ clouds routes workloads to the right hardware and region.

**Strengths:** Python-native developer experience with almost no infrastructure boilerplate; Scales from zero to thousands of GPUs with per-second, usage-based billing; Sandboxes are well suited to agentic and untrusted-code workloads; Multi-cloud capacity spans many regions with out-of-the-box observability and enterprise compliance

**Limitations:** Billed by real usage, so heavy GPU workloads can get expensive quickly without cost controls; Some advanced inference and enterprise features require working with the team rather than self-serve signup; The serverless model can feel less familiar to teams used to managing their own VMs or Kubernetes clusters

## PlusB

PlusB describes itself as a forward-deployed engineering firm rather than a self-serve app. Its pitch is that regulated and data-sensitive organisations should not have to send their data to a third-party model provider; instead, PlusB trains, optimizes, and loads models into the customer's own cloud VPC, private cluster, or edge devices. The company advertises sub-50ms inference latency targets, aggressive token-cost optimisation, and zero data retention, meaning nothing persists after a query is executed.

The deployment catalogue is organised around six systems: real-time voice AI that can replace legacy IVRs; autonomous agents that query databases and trigger workflows; document OCR for invoices, medical charts, handwritten logs, and contracts; domain-tuned translation; private chat that answers only from a customer knowledge base; and governance tooling that applies safety gating, content filtering, and compliance logging before any query touches core systems.

The engagement model is a three-step loop — audit and scope the data landscape and compliance requirements, build and deploy the models into the target environment, then monitor and maintain them with continuous safety checks and model upgrades. PlusB highlights education, healthcare, agriculture, and enterprise as target industries, and it also publishes independent research on small language models and compute-efficient architectures with open weights on Hugging Face.

**Pricing & Plans:** Paid engagement. PlusB does not publish public list pricing; deployments are scoped per client based on infrastructure, model choice, and compliance requirements. Prospective customers are routed to a "Talk to an Engineer" / "Start a Deployment" contact flow rather than a self-serve plan page.

- **Private LLM deployment:** Models are trained, optimized, and loaded directly into your cloud VPC, private cluster, or on-premise hardware so inference never leaves your environment.
- **Zero data retention:** The company states that queries do not persist after execution, which suits workloads in regulated and privacy-sensitive sectors.
- **Six production systems:** Voice AI, autonomous agents, document OCR, domain translation, private chat, and AI governance are offered as deployable, maintained components.
- **Voice AI and IVR replacement:** Real-time phone agents targeting sub-100ms conversational latency for replacing legacy touch-tone IVR flows.
- **Ongoing monitoring and upgrades:** Engineering teams run continuous performance monitoring, safety checks, and seamless model upgrades after go-live.

**Strengths:** Deployment-first model keeps sensitive data inside the customer's own infrastructure; Covers a broad production surface — voice, OCR, agents, translation, chat, and governance — under one engineering team; Explicit zero-data-retention stance is attractive for healthcare, education, and other regulated buyers; Open research and published model weights on Hugging Face build technical credibility

**Limitations:** No self-serve signup or transparent public pricing, so evaluation requires a sales/engineering conversation; Custom on-premise and VPC deployments imply longer lead times and higher effort than plugging into a hosted API; Independent benchmarks for the advertised latency and cost claims are not published on the marketing site
