Building Production AI Systems with Free Cloud GPUs

🚀 The Google Colab VS Code Extension

Enterprise AI Without Enterprise Costs

If you've been following my work on LLM-assisted code generation and AI reasoning, you know I'm always looking for ways to democratize AI development. During my recent work on cross-chain smart contract generation, I needed to rapidly prototype different transformer architectures for code translation. Previously, this meant juggling between local development, cloud instances, and Colab notebooks.

Now? I'm running everything from VS Code with zero context switching. Here's what changed my workflow:

Python - Loading Large Models on Free GPU
# Running this on a free T4 GPU in VS Code - no setup required
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

# Load a 7B parameter model - impossible on most local machines
model = AutoModelForCausalLM.from_pretrained(
    "codellama/CodeLlama-7b-hf",
    torch_dtype=torch.float16,
    device_map="auto"
)

# This runs at 50+ tokens/sec on Colab's T4
# On my laptop? 2 tokens/sec if I'm lucky
print(f"Running on: {torch.cuda.get_device_name(0)}")

The implications are staggering. We're talking about democratizing access to models that typically require $1000+ GPUs.

Production-Ready Fine-Tuning Pipeline

Let me share a practical example from my FSE 2025 research on blockchain-specific language models. Here's how I'm fine-tuning models for Solidity and Move smart contract generation directly in VS Code:

Python - Smart Contract Fine-Tuning Pipeline

from peft import LoraConfig, get_peft_model, TaskType

class SmartContractFineTuner:
    """

        self.device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
        print(f"🚀 Initializing on {torch.cuda.get_device_name(0)}")
        
        # Load model with 8-bit quantization for larger models
        self.model = AutoModelForCausalLM.from_pretrained(
            base_model,

        )
        
    def prepare_lora_model(self):
        """Configure LoRA for efficient fine-tuning"""
        peft_config = LoraConfig(
            task_type=TaskType.CAUSAL_LM,
            r=16,  # Rank
            lora_alpha=32,
            lora_dropout=0.1,
            target_modules=["q_proj", "v_proj", "k_proj", "o_proj"]
        )

        ]
    
    async def analyze_contract(self, contract_code: str):
        # Run agents in parallel on GPU
        tasks = [self._run_agent_analysis(agent, contract_code) 
                 for agent in self.agents]
        results = await asyncio.gather(*tasks)
        return self.aggregate_results(results)

Racecraft · Prologue , The Origin Story It Started With a Wine List and a Question About Racing How a happy-hour conversation in the Bay Area turned into a trustable AI race coach , and then into a second version that runs entirely on a phone, on the NPU. This is the prologue to a five-part series. Two years ago(1st November, 2024) I was in the Bay Area for a GDE Summit. If you've never been: it's a couple of days of talks among Google Developer Experts, the kind of people who get unreasonably excited about a new on-device runtime, and then , mercifully , a happy hour where everyone stops performing and just eats. We ended up at a restaurant(Puesto Santa Clara), a long table of GDEs, and I was doing the most important engineering of the evening: trying to decide which wine to order.

The Throughput Trap: Benchmarking vLLM on OpenXLA and the Reality of Production LLM Serving

vLLM Systems · DevLab 2026, Deep Dive I was recently invited by the Google TPU team to speak at the OpenXLA Summer DevLab 2026 . This post breaks down our deep-dive evaluation of the matured vLLM + OpenXLA stack, the fundamental engineering mismatches between CUDA and XLA serving paths, and why traditional capacity metrics are lying to you. If you are operating large language models at enterprise scale right now, your platform architecture team is likely staring at a massive infrastructure crossroads: Should we migrate our core serving workloads from GPUs to TPUs? Historically, NVIDIA's CUDA ecosystem was the only serious option for user-facing, low-latency LLM generation. But here in 2026, the economics and infrastructure options have transformed. Google TPUs are highly available, cheaper per chip, and the open-source serving stack built around vLLM and OpenXLA has officially achieved absolute production readiness. Yet, when our infrast...

A Split‑Brain Neuro‑Symbolic Training Method for High‑Velocity Autonomous Coaching from Telemetry

 Author: Rabimba Karanjai Scope: Problem statement + data methodology + model training (no deployment discussion) Abstract Real‑time coaching in motorsport is a safety‑critical learning problem : a system must map noisy, high‑frequency telemetry to short, actionable guidance that remains physically consistent and avoids hazardous recommendations . This paper proposes a “Split‑Brain” training formulation that separates (i) a semantic coaching target (what action/critique should be expressed) from (ii) a reflexive interface (how actions are represented as compact, verifiable tokens). The approach trains a Small Language Model (SLM) in the Gemma family [1] using QLoRA fine‑tuning [2] , and introduces a telemetry tokenizer plus teacher‑student synthesis pipeline to generate instruction‑action pairs at scale. Core contribution: a reproducible method to convert “ golden lap ” differential tel...
