[Michael Poluektov](https://www.linkedin.com/in/michael-poluektov/?isSelfProfile=false) - **Squeezing Intelligence out of a Fixed Compute Budget for ARC-AGI-3** An introduction to the ARC-AGI-3 competition, why it's relevant, and how the lessons learned from competing translate to the real world. The talk will centre around co-optimising the model, inference engine and harness for modern LLMs. We will compare different context management techniques employed by the participants, and the methods used to increase end-to-end decode throughput, including REAP, quantisation scheme selection, KV-cache offloading and request scheduling, and speculative decoding 2. Anton Borisov - **Snakes, Arrows and Other Curious Games in Apache Fluss** Building a Python client for Apache Fluss turns out to be a curious game of snakes, arrows, and a little Rust. In this talk, we'll explore how Python, Apache Arrow, and Rust come together to bring Fluss into the Python data ecosystem, uncovering a few interesting engineering trade-offs and surprises along the way. **Lightning Talks** 1. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Logistics** * Doors ope
