AI Interpretability Platform Launch

Founder Authority & Technical Motion Graphics

Adapt it.

Replace founder footage with new presenter and update on-screen text for 'MindFlow'.
Adapt 'InteractiveUISliders' to control 'emotional state' parameters and 'mindfulness intensity'.
Modify 'ConceptHighlightReveal' to highlight terms like 'anxiety triggers' and 'coping strategies' within simulated chat logs.
Update 'GridDataFlow' background with calming blue/green hues and adapt data visualizations to represent 'neurotransmitter levels' or 'CBT progress charts'.
Ensure all text content reflects the mental wellness domain, maintaining the serif/sans-serif typography style.
Maintain the 4 cuts/minute pacing and smooth ease-in-out motion language throughout.

Launch overview & key findings

A 99-second founder authority & technical motion graphics launch video by Goodfire, unveiled on April 17, 2025 with over 355K views on X. Evaluated at a 9.2/10 hook score with an editing tempo of 4 cuts per minute, the production demonstrates Goodfire's launch video introduces Ember, a neural programming platform that grants direct access to AI models' internal thoughts. Founder Amir demonstrates its ability to decode and manipulate AI concepts in images and language, and its application in biological discovery with Evo2. The video employs a clean, minimalist motion design style with interactive UI animations and a warm color palette to clearly convey complex technical breakthroughs.

The Hook
Introducing Ember: Neural Programming
“Today, we're announcing our $50M Series A and sharing a preview of Ember - a universal neural programming platform that gives direct, programmable access to any AI model's internal thoughts.”

Medium shot of the founder, then a quick cut to a title card. The camera is static on the founder.
Motion
Cross-dissolve transition from founder to title card, followed by a subtle grid background animation and text reveal.
Product Reveal
Decoding AI Model Thoughts
“Ember lets you decode what an AI model is thinking, and then directly manipulate those thoughts. For example, here's a model that's generating images. We can see that it's thinking about 'dim street lighting' and 'atmospheric effects'. We can also see that it's thinking about 'lions'. We can then directly manipulate these neural concepts. For example, we can increase the 'lion' concept, and the model will generate more lions. We can also decrease the 'Santa hat' concept, and the model will generate fewer Santa hats. This gives us direct, programmable access to the model's internal thoughts.”

Close-up on UI elements, then a wider shot of the application interface. The camera pans and zooms to highlight specific interactions.
Motion
Interactive UI elements animate on hover and click. Data visualizations (sliders, bar graphs) update in real-time. Text highlights and expands. Smooth camera pans and zooms to focus on key UI interactions.
Feature Teaser
Uncovering Biological Concepts with Evo2
“Ember also lets us interpret language models. For example, we can see that this model is thinking about 'consciousness' and 'sentient beings'. We can then directly manipulate these neural concepts to steer the model's behavior. We're also using Ember to uncover novel biological concepts with Evo2. For example, we can see that this model is thinking about 'alpha helix', 'beta sheet', and 'tRNA'. This allows us to understand and design AI systems in a completely new way.”

Camera
Similar to the previous scene, focusing on UI elements and data visualizations. The camera smoothly transitions between different application views.
Motion
Data visualizations animate to show changes over time. Text appears with a subtle fade-in and scale. UI elements slide into view. A grid background subtly animates.
Call to Action
Building Safe and Powerful AI
“We recently raised $50 million to further our research into understanding and designing AI systems. We believe that interpretability is key to building safe and powerful AI. We're excited to share Ember with the world and empower researchers and developers to build the next generation of AI.”

What's actually going
Camera
Returns to a medium shot of the founder, then cuts to a black screen. The camera is static on the founder.
Motion
Founder speaks directly to the camera. A final title card with a blurred background and text reveal. The video ends with a fade to black.

Synthesizable in Remotion · key components of the goodfire-ember-launch-template template.

GridDataFlow

A subtle, animated grid background with dashed lines, often overlaid with translucent, layered rectangular planes that highlight data flow or conceptual connections. These planes can change color or opacity to indicate activity.

+ Code construction recipe

Use Remotion's <Grid /> component for the background. Implement <AbsoluteFill /> with multiple <Rect /> components for the planes, animating their `opacity`, `x`, `y`, and `scale` properties using `interpolate` and `spring` functions. Use SVG filters for subtle glow or blur effects on active planes.

InteractiveUISliders

UI sliders and input fields that dynamically update values, often accompanied by real-time visual feedback like changing percentages or expanding bar graphs. Text elements highlight on interaction.

+ Code construction recipe

Create custom slider components using `input type='range'` and animate their `value` and associated visual elements (e.g., bar width, text color) using `interpolate` based on user interaction or simulated data. Use `useCurrentFrame()` and `spring` for smooth transitions of UI elements into view.

ConceptHighlightReveal

Key textual concepts or data points are highlighted with a colored background or underline, often appearing with a subtle scale-up or fade-in animation. This is used to draw attention to specific terms within a larger body of text or data.

+ Code construction recipe

Wrap target text segments in `<span>` elements. Animate the `backgroundColor` or `textDecoration` property using `interpolate` or `spring` based on a timed sequence. For scale-up/fade-in, use `transform: scale()` and `opacity` with `spring` for a natural feel.
