Open-Source Image Generation: Diffusion Models & LoRA - AI Build & Learn

10 July Online

About this event

Welcome to AI Build & Learn, a weekly AI engineering stream where we pick a new topic and learn by building together.

​This event is about generating images with AI. There's no single model we're locked into, the point is to explore what's out there and actually try a few. We'll focus on open-source models, but you're welcome to bring commercial ones (DALL·E, Midjourney, and friends) if you want to compare.

​We'll try to look at both major families: diffusion-based models (the dominant approach today) and transformer-based / autoregressive image models. I'll research and try some of the best open-source options ahead of the stream, and if time allows we'll also try fine-tuning with LoRA to teach a model a new style or subject.

​Some things to look up to get started:

​Open-source models:

  • ​FLUX.2 (Black Forest Labs): current open-weight quality benchmark; DiT backbone, up to 4MP, multi-image reference
  • ​Stable Diffusion 3.5 / SDXL (Stability AI): deepest ecosystem — LoRA, ControlNet, inpainting, countless fine-tunes
  • ​Qwen-Image (Alibaba): strong all-rounder, especially good at rendering text (including Chinese)
  • ​Z-Image / Z-Image-Turbo: Apache-2.0, near FLUX.2 quality in just a few steps (fast and commercial-friendly)
  • ​HunyuanImage (Tencent): another high-quality open-weight option

​Tooling:

  • Practical examples

​​​Community challenge (optional)
​​​Try spending 30–90 minutes during the week learning or building something related to the topic, then share what you’re working on in Slack.

​​​Note on Flyte / Union
​​​You may see Flyte used in some demos. Flyte is an open-source AI orchestration platform maintained by Union (where I work) for building scalable, durable, and observable AI workflows. You do not need to use Flyte to participate.

Frequently asked questions

Quick answers about how DevFound's AI matching, resumes, and referrals work.

DevFound's AI Copilot ingests your profile, goals, and live job data to deliver curated matches in seconds. Every match includes a resume variant, suggested referrals, and interview prep so you can act immediately. The more feedback you provide, the sharper the Copilot becomes.

AI-led job searches shrink the hours spent sifting through boards and formatting resumes. DevFound pairs automation with your personal outreach, so you reserve energy for interviews and negotiation. Traditional networking still matters, but AI gives you a lift before you even send a message.

Modern AI roles expect comfort with production-grade code, data fluency, and practical ML tooling. The strongest candidates pair deep technical chops with storytelling—translating model impact to product, GTM, and exec partners. Continuous learning keeps you ahead as stacks evolve.

DevFound rewards active seekers. Keep your profile fresh, respond to match quality prompts, and enable alerts so you never miss a role. The AI prioritizes companies and teams that align with your feedback, accelerating both introductions and interview invites.

High-density tech hubs continue to host the deepest AI talent pools, yet distributed teams are catching up fast. Use DevFound filters to hone in on onsite, hybrid, or fully remote roles and watch openings expand across time zones.

DevFound aggregates thousands of remote AI openings and flags the nuances—core hours, async culture, and visa needs—up front. The Copilot also recommends how to position your distributed work experience so hiring managers know you can thrive on a remote team.
