Episode Title: $140M Powers Fal's 10X Image Performance Peak
Date: December 30, 2025
Host: Jaden Schaefer
Overview
In this episode, Jaden Schaefer explores major news from FAL AI, which has just completed a $140 million Series D raise and unveiled a significant upgrade to image generation technology. Built atop Black Forest Labs’ open-source model (Flux 2), FAL’s new “Flex 2 Dev Turbo” introduces a leap in speed and cost efficiency, promising to reshape how generative imagery is accessed and deployed by developers and enterprises. Jaden explains the technical innovations, licensing nuances, and the broader implications for the AI ecosystem, particularly how open model optimization may set the future direction for the whole industry.
Key Discussion Points & Insights
1. FAL AI’s $140M Funding and Breakthrough Model Launch
- FAL AI has just raised $140M in a Series D round.
- The big news: Launch of Flex 2 Dev Turbo, a model promising images “10 times cheaper and 6 times more efficient” than existing offerings.
- The host frames this as “the direction that all of the AI companies, all the large AI hyperscalers... are going to be moving in” [02:00].
2. Technical Foundations and Innovation
- Built on Flux 2: Original, open-source model from Black Forest Labs—also the base for Grok’s image capability on X (formerly Twitter).
- Lora Adapter: Flex 2 Dev Turbo is not a standalone model but a “Lora adapter”—“a lightweight optimization layer that essentially attaches to the original Flex 2 base model” [04:15].
- Result: “dramatically improves the performance” of Flux 2 without requiring full model retraining or grossly increased hardware.
- Delivers “high quality image generations in a fraction of the time and at significantly lower cost” [04:40].
3. Licensing & Accessibility
- Available on Hugging Face—but with a significant caveat:
- Distributed under Black Forest Labs’ custom non-commercial license.
- Jaden: “It is not licensed for commercial deploy... allows personal use, research, internal evaluation, but doesn’t let you use this for any revenue generated applications without a separate agreement” [17:40].
4. FAL’s Business Model and “Infrastructure over Models” Philosophy
- FAL is positioning itself as “an AI media infrastructure,” not just a model vendor [07:30].
- They act as a “centralized hub for real time generative media,” providing APIs for open and proprietary models spanning image, video, audio, and 3D generation.
- Notable claim: “More than 2 million developers are now using their platform... they serve billions of assets each month” [09:15].
- Usage-based pricing: “charging per token or per asset... just like you would pay OpenAI for using their model” [10:10].
5. Technical Metrics & Benchmarks
- Flex 2 Dev Turbo’s improvements:
- Step Reduction: From 50 inference steps (original) to just 8 for comparably high-quality images [13:00].
- Enabled By: “Customized DMD2 distillation techniques” [13:15].
- Evaluation: Achieves the highest ELO score among open-weight image models, 1166 (beats Alibaba and others on the YUP benchmark).
- Speed & Cost: “It can create an image for $0.008 in just 0.66 seconds” [14:40].
- “Basically the lowest price that is currently on the leaderboards” [14:50].
6. Impact and Use Cases
- Jaden highlights how cheaper, faster image generation will “make a huge difference” for companies with large-scale image generation needs, such as Suno AI (music generator that dynamically creates millions of album covers with each song) [15:30].
- Even companies traditionally seen as doing something else (music, text) are significant image generators behind the scenes.
- “If you could make this thing six times faster and ten times cheaper... that would be an incredible innovation.” [05:30].
Notable Quotes & Memorable Moments
"What’s incredible here is [FAL has] been able to build something on top of that model to create images that are 10 times cheaper and six times more efficient." — Jaden Schaefer [01:15]
"Flex 2 Turbo is not a full standalone image model... Instead it’s what's called a Lora adapter. This is a lightweight optimization layer that essentially attaches to the original Flex 2 base model and... dramatically improves the performance." — Jaden [04:12]
"When you start building software on top that optimizes the models that are there, that nobody else has, like this improved version of Flux, I think that’s when these companies can become really, really valuable." — Jaden [11:35]
"When the original Flex 2 required roughly 50 inference steps to produce a really high quality image, Turbo achieves a really comparable output in just eight steps. So going from 50 steps to eight steps, this is a massive improvement." — Jaden [13:03]
"It can create an image for $0.008 per image. It’s basically the lowest price that is currently on the leaderboards." — Jaden [14:42]
"Despite you being able to access this license, it’s not licensed for commercial deploy... it allows personal use, research, internal evaluation, but doesn’t let you use this for any revenue generated applications without a separate agreement." — Jaden [17:40]

Tone and Concluding Thoughts
- Jaden is enthusiastic about the broader industry significance—emphasizing how such advancements will not only benefit AI insiders but also improve user experience for anyone waiting on slow, expensive image results.
- There’s a clear hope that giant platforms (OpenAI, Anthropic, etc.) will “take some of this technology as well” to accelerate improvements industry-wide [05:45].
- He’s realistic about commercial limitations (non-commercial license) but optimistic about future releases and licensing flexibility.
"I'm really excited to see if we see similar technology rolled out in other big players and we see a speed up in the overall image generation space." — Jaden [18:00]
