A while back I did a deep dive into abliterating Gemma 3 12B for use as an uncensored text encoder in LTX-2 video generation. The process worked but involved a lot of manual steps: running Heretic, merging safetensor shards, converting to ComfyUI format, quantizing to FP8, building GGUF quants. I got tired of doing it all by hand, so I built heretic-docker to automate the whole thing.
LTX-2 is Lightricks’ open-source video generation model, and it uses Google’s Gemma 3 12B as its text encoder. Lets explore how to make an uncensored model and if it matters for LTX2 video generation.
Today we’re going to do ‘Cap’ which is another easy hackthebox challenge. This will be similar to our previous challenge where we will go through without reviewing how it was done, then compare afterward with the solution.
For over a decade I've delivered a wide range of projects for clients across different industries.
Architected and built a multi-tenant SaaS application from the ground up using Laravel and Vue.js. Designed the API layer, tenant isolation, subscription billing integration and role-based access control. The platform scaled to serve thousands of active users across multiple organisations.
Took over a large legacy PHP codebase for an established business and incrementally migrated it to a modern Laravel architecture. This included restructuring the database layer, building a RESTful API, implementing automated testing and deploying with zero downtime to ensure business continuity throughout the transition.
Developed a custom Laravel API backend for an e-commerce platform, integrating with third-party payment gateways, inventory management systems and shipping providers. Focused on security hardening, PCI compliance considerations and performance optimisation under high traffic loads.
Designed and managed production server environments for multiple clients, including load-balanced configurations, automated deployment pipelines, firewall management, email server setup with full DKIM/SPF/DMARC compliance and ongoing monitoring. Provided security audits and vulnerability assessments across all environments.
Built internal tools and workflow automation systems for small and medium businesses. Everything from CRM-style platforms to booking systems to data dashboards. These projects typically involve close collaboration with non-technical stakeholders to translate business requirements into clean, maintainable software.
Built and customised Shopify stores for clients across retail, services and hospitality. This includes custom theme development, app integrations, payment and shipping configuration, SEO and performance tuning. Most of these projects involved taking an existing store that wasn't working well and rebuilding it into something the client could actually manage themselves.
Set up automated build and deployment pipelines using GitHub Actions, GitLab CI and shell scripting. Configured staging and production environments with automated testing, zero-downtime deployments and rollback strategies. Just reliable pipelines that don't need babysitting.
Integrated LLM-based features into existing Laravel applications for clients, including AI-assisted content generation, intelligent search and automated data processing. Built RAG pipelines for domain-specific knowledge retrieval, fine-tuned open-source models for client use cases and set up local inference servers for clients who needed to keep their data on-premise. Also release my own open-source models on HuggingFace.
