Laguna by Poolside
Poolside
Poolside's family of open Mixture-of-Experts foundation models for agentic coding — XS.2 runs locally, M.1 reaches 72.5% on SWE-bench Verified.
Key features
- Two Model Sizes: Laguna XS.2 (33B total / 3B active) and Laguna M.1 (225B total / 23B active) target different latency and capability needs.
- Mixture-of-Experts Architecture: Routes each token through a subset of experts for efficiency at large scale.
- Local Deployment: XS.2 is small enough to run on a Mac with 36 GB of RAM via Ollama under an Apache 2.0 license.
- Strong SWE-bench Results: XS.2 hits 68.2% and M.1 reaches 72.5% on SWE-bench Verified.
- Bundled Coding Agent: Ships 'pool,' a lightweight terminal-based coding agent.
- Agent Client Protocol: Includes a dual ACP client-server used internally for agent RL training and evaluation.
Best for
- Local Agentic Coding: Running XS.2 on a laptop for private, offline code generation and editing.
- High-Capability Code Tasks: Using M.1 for harder, long-horizon software engineering work.
- Self-Hosted Deployments: Building on open weights to avoid third-party API dependencies.
- Research & Fine-Tuning: Adapting permissively licensed weights for custom coding workflows.
- Benchmarking: Evaluating agentic coding performance against SWE-bench Verified and Pro.
LTX-2
Lightricks
DiT-based audio‑video foundation model delivering synchronized high-fidelity video and audio with production-ready pipelines and LoRA trainer.
Key features
- Synchronized Audio‑Video Generation: End-to-end model architecture that jointly generates coherent video frames and matching audio (including a vocoder) so motion, dialogue, ambience and music are time-aligned.
- Production‑Ready Pipelines: ltx-pipelines provides high-level, CLI-capable pipelines (text-to-video, image-to-video, video-to-video, keyframe interpolation) that handle model loading, encoding/decoding, memory management and file I/O for production workflows.
- LoRA & IC‑LoRA Trainer: ltx-trainer includes tools and configs for fast LoRA and IC‑LoRA fine-tuning (motion, style, likeness), enabling many useful adapters to be trained quickly and reproducibly.
- Performance & Memory Optimizations: Supports FP8 transformers, gradient-estimation denoising to reduce steps, multi-stage two-stage pipelines (latents + spatial upscaler), and other memory optimizations for improved throughput and lower compute cost.
- Multi‑Scale Temporal & Spatial Upscaling: Provides temporal upscalers and spatial upscalers in multi-stage pipelines to increase frame-rate (FPS) and resolution while balancing speed and visual quality.
- Modular Core Components: ltx-core exposes schedulers, guiders, patchifiers, loaders and SingleGPUModelBuilder for custom inference stacks and research customization.
- Text Encoding & Conditioning: Integrates Gemma text encoder and multi-keyframe conditioning and 3D camera logic for precise control over scene content, style, and temporal continuity.
- Dataset & Training Utilities: Includes dataset preprocessing tools (resolution buckets, frame bucketing, sequence-length rules) and accelerate configs for distributed GPU training and large‑model fine-tuning.
- Synchronized audio and video generation in a single model
- Native 4K fidelity and up to 50 fps support
- Generations up to 10 seconds with synchronized audio
- DiT-based transformer architecture with separate video and audio VAEs and vocoder
- Official Python packages: ltx-core (model & utilities), ltx-pipelines (inference pipelines), ltx-trainer (LoRA & fine-tuning)
- Multiple pipeline types: text-to-video, image-to-video, video-to-video, keyframe interpolation
- Two-stage and distilled pipelines with optional spatial upscaler and temporal upscaler
- LoRA and IC-LoRA training support for fast adaptation and style/motion/likeness tuning
- FP8 transformer support and gradient-estimation denoising (reduce steps while preserving quality)
- Production-ready features: CLI, model loaders, file I/O, memory optimizations, and multi-GPU inference stack
- Integration options: PyTorch codebase, Diffusers, ComfyUI workflows, Hugging Face model hosting, API providers
Best for
- Producing short synchronized audio-video clips for creative content: generate up to multi-second clips with aligned dialogue, ambience and music for social media or cinematic previews.
- Custom LoRA fine-tuning for style or likeness: train LoRA adapters to capture a specific motion style, actor likeness, or audio voice with limited compute and integrate them into inference pipelines.
- Video-to-video editing and transformation: perform video-to-video translations, inpainting or interpolation using IC‑LoRAs and multi-stage pipelines for high-quality, temporally consistent results.
- High-fidelity production rendering: generate high-resolution (4K-capable) outputs with temporal upscaling and spatial upscalers for polished, production-ready artifacts and post-processing.
- Research and model development: experiment with diffusion schedulers, gradient-estimation loops, and FP8 transformer variants to test performance-quality trade-offs and novel conditioning strategies.
- Building integrated APIs and services: deploy the inference pipelines and model loaders in server environments to provide programmatic access to audiovisual generation for apps and studios.
- Generate high-fidelity synchronized audio-video clips from text prompts
- Image-to-video and video-to-video transformations and style transfer
- Create multi-keyframe animated sequences with precise frame-level control
- Rapid LoRA/IC-LoRA fine-tuning to adapt style, motion, or voice likeness
- Production pipelines for VFX, advertising, game cinematics, and content prototyping
- Research and experimentation with multi-modal diffusion and temporal upscaling techniques
