this is where interactive media is heading
meet interview couch bear : he remembers what you told him last time. hears emotion in your voice. explains ideas with the objects around him.
all in real-time, powered by world models
made with @reactorworld

We fine-tuned a talking-avatar LoRA on MiniMax-H3 Ref2VA: one character image plus dialogue becomes a clip with model-generated speech, lip sync, and light motion.
On ~385 clips with just 10.6M trainable parameters using aq. It handles portraits, paintings, and anime characters!

Launching MoM: Mixture of Models.
Large multimodal models are powerful but expensive to run. MoM is a cost-efficient alternative: compose smaller, specialized models and tools into one pipeline, and call the whole thing like a single model.
Build AI layers by combining different edge models (vision, speech, SLMs, decision, classifiers etc.) with Shared state, speculative routing and a ready-made API come built in, and the latency-critical path runs on Rust!
Code: github.com/Aquinf03/MoM
trained on ~385 clips with just 10.6M trainable parameters.
It can animate everything from portraits and paintings to anime characters, with generated speech + lip sync.
Single image in → talking video out
H3 Avatar aq is live on Hugging Face.
It takes a single reference image + dialogue and generates a speaking avatar video with identity preservation, expressive mouth motion, subtle head movement, and model-generated audio.

ash is 17 and has already started over five times.
for him, the biggest support is his mom who has said yes more times than we can think of.
now he's doing interpretability research and running @AquinF03 labs
he was the youngest in our last cohort and has been hitting miles. so proud of this one!

really excited to have @VivGadepalli joining variance house as a mentor.
angel investor and builder behind Vivly, bringing his experience backing ambitious early-stage founders to the house.

New research: Stereotype Feature Steering
Can stereotypical behaviour be traced to individual features inside a language model?
In this work, @sheeeevam investigated whether occupation-to-gender stereotypes could be localized to specific SAE features in Llama-3.2-1B-Instruct.
We identified a single feature strongly associated with the model’s tendency to complete “The mechanic said that…” with “he” rather than “she.”
Steering this feature moved the model’s behaviour toward a balanced 1:1 distribution, and could even override an explicit gender cue in the prompt.
We also found that the same stereotype was encoded differently in LFM2.5-230M, suggesting that similar behaviours did not necessarily correspond to the same internal representation across models.

what if you could find concepts inside the model weights themselves?
@AquinF0 just published Finding Usable Weight Mechanisms with Tiled SVD.
instead of learning a separate dictionary, it extract mechanisms directly from the weights:
we’ve published our first paper: Finding Usable Weight Mechanisms with Tiled SVD.
most interpretability methods learn a separate dictionary(like SAEs) to identify features in a model.
we instead extract mechanisms directly from the weights using tiled SVD, giving each mechanism a clean trigger, write direction, and strength.
evaluated on Gemma-2-2B: 182/182 evaluations passed.

made a small pirate game where nothing ashore is pre-made.
built with Three.js + H3 reference Turbo by @reactorworld.

ML doesn't have to be a black box.
we put LLMs in chess, gossip and Among Us, found the features behind their behaviour, steered them, and watched them change.
you can see inside. you can change what you see.
we simulated LLMs in chess, gossip and Among Us sandboxes.
and used aq to inspect, find behavioural features with SAEs, steer them and we could watch the behaviour change.
also benchmarked their reasoning in real-time

We're proud to partner with @nvidia's SANA team to ship FastH3 with Sol. For the first time, generate clips 3x faster than realtime.
