AI Infra Decentralization

Why Indian Startups & Dev Teams Should Own Their AI Infrastructure

Cloud GPU bills are climbing. Your code, your data, and your AI models live on someone else’s hardware.

Consider a typical Bengaluru fintech startup — six developers, a couple of AI models powering credit scoring and document analysis, some RAG pipelines for internal knowledge. A conservative estimate for their monthly cloud compute bill: ₹2–4 lakhs. GPU instances for inference, API calls to OpenAI or Anthropic for coding assistance and document generation, storage for embeddings. Over a year, that’s ₹25–50 lakhs flowing out the door — and they own nothing at the end of it.

This isn’t unique to AI-first companies alone. In 2026, every development team started to depend on AI. Your frontend developers are using Copilot or Claude for code generation. Your QA team is using LLMs for test case synthesis. Your product managers are running meeting transcriptions and documentation through AI. Your DevOps engineers are using AI-assisted debugging and log analysis.

AI is no longer a feature you build. It’s the oxygen your entire team breathes. And right now, most Indian teams are renting that oxygen by the hour from servers they’ve never seen, in countries they’ve never visited.

After 20 years of building enterprise systems — from trading platforms to credit analysis tools — I believe this dependency is both unnecessary and increasingly risky. And for the first time, the technology exists to eliminate it practically.

Think about what’s happening: Your entire codebase, your architecture decisions, your business logic, your test strategies, and your infrastructure blueprints are being sent, query by query, to servers operated by companies whose primary business is collecting and leveraging data. Even if they promise not to train on your inputs today, policies change. Companies get acquired. Terms of service evolve, but end of the day they have your data all our data.

A locally hosted AI model running on your own hardware eliminates this exposure entirely. Not through policy or promise — through physics. Data that never leaves your machine cannot be intercepted, collected, or subpoenaed.

The Three Taxes Every Team Pays for Cloud AI

Tax 1: The Recurring Compute Tax

An NVIDIA H100 GPU in the cloud costs $2–5 per hour. For a modest 6-developer team running a mix of inference, coding assistance, and fine-tuning for 6 hours a day, that’s ₹3–5 lakhs per year. Layer in API costs for OpenAI/Anthropic usage — at $15–60 per developer per month for paid tiers — and the total climbs to ₹5–8 lakhs annually. Every year. Forever. You never own anything.

Would you rent a car for ₹5 lakhs a year when you could buy one for ₹15 lakhs and drive it for 7 years?

Tax 2: The Data Sovereignty Tax

India’s Digital Personal Data Protection (DPDP) Act of 2023 classifies health data, financial data, and personal information as sensitive. Every time your AI system sends a loan application, a patient record, or a legal document to a cloud GPU, that data crosses a trust boundary you don’t control.

But even beyond regulated data — your proprietary code, your business logic, your competitive insights are being sent to external servers with every AI-assisted coding session. For any company whose value lies in its intellectual property, this is a slow leak of competitive advantage.

Tax 3: The Vendor Lock-in Tax

OpenAI changed their pricing three times in 2024. Google deprecated Bard and pivoted to Gemini, breaking API integrations. AWS GPU instances have waitlists during peak demand. When you build on cloud AI, your roadmap is hostage to someone else’s business decisions.

I’ve seen teams scramble to rewrite integrations because a model they depended on was deprecated with 30 days’ notice. That’s not infrastructure. That’s a subscription to anxiety.

What Changed in December 2025

For years, the argument against owning AI hardware was simple: nothing could match NVIDIA’s CUDA ecosystem for AI workloads. Cloud GPUs were the only practical option. And attempts to cluster consumer hardware for AI were disappointing at best.

Earlier in 2025, YouTuber and infrastructure engineer Jeff Geerling — known for rigorous, no-nonsense hardware testing — had documented the limitations. NetworkChuck’s earlier attempt to cluster five Mac Studios showed a painful 91% performance degradation. More machines made things slower. The networking was the bottleneck.

Then three things landed within weeks of each other in late 2025, and together they changed the equation fundamentally:

Apple shipped RDMA over Thunderbolt 5 in macOS 26.2. This reduced inter-machine latency from 300 microseconds to 5–9 microseconds — a 50× improvement. For the first time, multiple Mac Studios could share memory and compute as if they were a single machine.

Exo 1.0 launched with native RDMA support, providing open-source clustering software that makes distributed AI inference across Mac Studios as simple as plugging in a cable.

MLX matured rapidly. Apple’s machine learning framework now runs large language models at competitive speeds on Apple Silicon, with benchmarks showing MLX on M3 Max performing within 25–35% of an NVIDIA Tesla V100 — a data center GPU — while consuming a fraction of the power.

Jeff Geerling’s 1.5TB Cluster: Proof It Works

In December 2025, Jeff Geerling published detailed results from testing a cluster of four M3 Ultra Mac Studios loaned by Apple — 1.5TB of unified memory connected via Thunderbolt 5 RDMA. The results were transformative compared to earlier attempts:

He ran models that no single machine could handle — DeepSeek R1 at 671 billion parameters, Kimi K2 Thinking at 600GB+. The RDMA connection delivered 25 tokens per second on Kimi K2, compared to just 5 tokens/sec over standard Thunderbolt networking. The entire cluster, four machines running massive AI models, drew approximately 600 watts total — less than a single NVIDIA H200 at full load.

As Geerling noted, a single M3 Ultra Mac Studio had more AI inference horsepower than his entire multi-node Framework Desktop cluster, at half the power draw. The $40,000 Mac cluster ran models that would require $780,000+ of NVIDIA H100 hardware.

Research from academia backs this up. A peer-reviewed study on Mac Studio clusters running the 132-billion-parameter DBRX model found them to be 1.15× more cost-efficient than NVIDIA H100 infrastructure in terms of throughput per dollar.

The breakthrough isn’t any single technology. It’s the convergence: RDMA made clustering fast, Exo made it simple, and MLX made Apple Silicon competitive for inference. Pull any one piece and the puzzle doesn’t work. All three arrived within the same month.

The Dual-Purpose Insight

Here’s what I find most interesting — and what I haven’t seen articulated clearly anywhere, including in Geerling’s excellent coverage.

When a startup buys cloud GPU time, that’s a single-purpose expense. It does AI compute. Nothing else. Your developers still need laptops. You’re paying twice: once for the humans’ machines, once for the AI’s machines.

A Mac Studio is different. Each machine is simultaneously:

A developer workstation — more powerful than a MacBook Pro, with 128GB unified memory, running VS Code, your development work, Docker, Chrome with 50 tabs, everything a full-stack developer needs daily.

An AI coding assistant host — running a local 70B model that handles code generation, documentation, debugging, and review without any data leaving the machine. No Copilot subscription. No API calls. Complete code privacy.

A cluster compute node — the same machine, when clustered with teammates’ machines via Thunderbolt 5, participates in distributed inference capable of running models larger than anything a single NVIDIA consumer GPU can handle.

This means the infrastructure cost is the developer hardware cost. You’re not buying AI infrastructure on top of developer machines. You’re buying machines that serve all three purposes. For a 6-developer startup, this eliminates the entire category of “separate AI infrastructure budget.”

“The best infrastructure investment works for you around the clock — as a workstation during the day, as a private AI coding assistant during reviews, and as a cluster node when you run your models.”

The Remote Work / WFH / Connect from home

Here’s a practical consideration that matters enormously in India’s post-COVID work culture.

When a developer works remotely, or wanted opted to work from home, they don’t need to take the Mac Studio home. They connect to it — via macOS built-in screen sharing, SSH + VS Code Remote, or simply by using a lightweight MacBook Air as a thin client that connects back to their Studio in the office.

The Studio sits in the office doing triple duty: personal workstation when the developer is in office, remote compute node when they’re working from home, and AI cluster node when the team needs to run large inference workloads.

No hardware sits idle. Ever. That’s infrastructure efficiency that cloud architectures can’t match, because cloud instances sit idle (and billing) during your team’s off-hours unless you build complex auto-scaling — which most small teams never do.

The Numbers: 5-Year Total Cost of Ownership

I modelled three scenarios for a 6-developer team over 5 years. The comparison includes the cost of developer machines, which cloud-dependent setups require separately.

The Mac Studio cluster delivers the lowest 5-year cost while providing the most usable AI memory, complete data and code privacy, silent operation, and developer workstations included. And after 5 years, you still own hardware with meaningful resale value.

The Energy Argument India Can’t Ignore

A single NVIDIA H100 GPU draws 700 watts under load. A four-node Mac Studio cluster draws approximately 200 watts under full AI inference — less than a ceiling fan and a laptop running simultaneously.

For India, where power generation is still significantly coal-dependent and electricity reliability varies by region, this isn’t abstract:

The entire Mac Studio cluster runs on a standard office UPS. No server room. No special cooling. No three-phase power connection. No dedicated AC unit fighting the heat output of GPUs running at 85°C.

In Bengaluru’s climate, the Mac Studios run at room temperature year-round. In Chennai’s or Delhi’s summers, your existing office AC handles them without modification. Jeff Geerling’s testing confirmed that even under sustained AI workloads, the thermal output was manageable with standard ventilation.

Try running a rack of NVIDIA GPUs in a Bengaluru co-working space and see how quickly your neighbours complain about the noise and the heat.

An honest caveat: I’m not suggesting Mac clusters replace data centre GPUs for training large foundation models. Training a 70B model from scratch requires thousands of GPUs and is NVIDIA’s domain. What I’m arguing is that for inference — running models, serving predictions, powering AI-assisted development, fine-tuning on your domain data — the economics and practicality of Apple Silicon clusters now decisively favour on-premise deployment for small and medium teams.

What a Setup Actually Looks Like

# Hardware: 4× Mac Studio M4 Max, 128GB each
# Connected via Thunderbolt 5 in ring topology
# Total: 512GB unified memory, 160 GPU cores
# Install the AI stack (takes 10 minutes per machine)
brew install python
pip install mlx mlx-lm
pip install exo-ai
# Download a model (one-time, shared across cluster)
mlx_lm.convert --hf-path meta-llama/Llama-3.1-70B-Instruct
# Start the cluster — Exo auto-discovers nodes via RDMA
exo
# Your AI is now available on an OpenAI-compatible API
# Point any app from api.openai.com to your local IP
# http://192.168.1.x:52415/v1/chat/completions
# Zero application code changes needed.

No CUDA driver installation. No Docker + NVIDIA Container Toolkit configuration. No IAM roles and VPC setup. No monthly invoices. Exo provides an OpenAI-compatible REST API, meaning any application currently calling OpenAI or Anthropic can switch to the local cluster by changing a single endpoint URL.

Your developers can even point their AI coding assistants — tools like Continue.dev or Cody — at the local model instead of cloud APIs. Every code completion, every documentation generation, every debugging session stays entirely on your hardware.

Who Should Consider This?

Not every team needs private AI infrastructure. If you’re a 2-person team making occasional API calls, cloud is fine. But if any of the following apply, the math is worth examining:

Any development team of 4+ people where every developer uses AI-assisted coding daily. You’re already paying for Copilot/API subscriptions, plus your code context is leaving your premises with every query. A local model eliminates both the cost and the exposure.

Fintech companies processing financial data through AI models. RBI data localization guidelines are real, and enforcement is tightening.

Healthcare AI startups analysing patient records or diagnostic imaging. The DPDP Act makes cloud processing of health data a compliance minefield.

Legal technology firms where client-attorney privilege demands that documents never traverse third-party infrastructure.

Regional language technology teams building models for Hindi, Tamil, Kannada, Telugu. Your curated Indian language training data is your competitive moat — don’t send it to foreign servers.

Any company spending more than ₹3L/year on cloud AI compute and API subscriptions. At that threshold, ownership becomes cheaper within 18 months.

What Apple Is Doing (Quietly)

Apple’s strategy in AI has been widely misunderstood. While everyone focuses on NVIDIA’s dominance, Apple has been building something architecturally different.

Their Private Cloud Compute infrastructure — which powers Apple Intelligence — runs on Apple Silicon servers, not NVIDIA GPUs. They recently upgraded these servers directly to M5 chips, skipping two entire generations. They trained their own foundation models on Google TPUs rather than NVIDIA GPUs — a deliberate strategic choice to avoid NVIDIA dependency.

The enabling of RDMA over Thunderbolt 5 wasn’t an accident. Apple loaned Mac Studio clusters to people like Jeff Geerling specifically to demonstrate the capability publicly. They want this story told. They’re laying the groundwork for Mac clusters to become a legitimate AI compute platform — not to compete with data centres, but to make on-premise AI viable for smaller organisations.

Whether Apple is right about the long-term future of distributed vs. centralised AI, the present is clear: their hardware is now capable enough for serious inference workloads, and the software ecosystem has matured to make it practical.
