GEPA: use execution feedback to improve prompts and agent programs

Lakshya Agrawal’s publisher notes describe GEPA’s reflective search: inspect execution traces and errors, propose text changes, score candidates, and retain alternatives that work well on different examples. Optimize Anything extends the editable object from prompts to programs, skills and policies. The reusable method depends on informative feedback and a suitable evaluator. The talk’s large benchmark gains lack complete evaluation protocols in the presentation, so they do not establish a universal advantage over reinforcement learning.

Teaching LLMs to Speak Spotify — Yves Raimond & Jacqueline Wood, Spotify

Yves Raimond and Jacqueline Wood explain how Spotify connects an LLM to catalog items through semantic IDs. A staged training recipe first grounds new catalog embeddings against a frozen backbone, then adapts the model to recommendation tasks. The talk also covers editable taste profiles, decoding choices and listener-aware judges. Reported evaluation figures lack sufficient dataset detail for a general performance comparison.

Physical AI's Next Bottleneck Is Finding the Right Video — Rafael Levi, Bright Data

Rafael Levi demonstrates searching video for specific actions before collecting training clips. Bright Data’s workflow returns relevant segments and match information, reducing the need to download entire recordings to find a useful event. The talk distinguishes discovering human-action footage from the additional processing needed for robot training. Retrieval relevance does not by itself establish data suitability or downstream model quality.

Document context layers: combine fast parsing with selective source inspection

Jerry Liu’s publisher notes separate document parsing, storage and recurring workflows from an agent’s iterative retrieval loop. A fast initial parse can make a collection searchable, followed by deeper visual inspection of selected tables or charts. The design preserves source citations and flags uncertain extracted values before they enter downstream systems. Accuracy requirements and latency goals in the talk are workload constraints, not demonstrated performance guarantees; confidence calibration and universal parser superiority are not established.

From Scratch to SOTA: Training a 3B State-Space Vision Model — Krishna Prasad Srinivasan, Sarvam

Krishna Prasad Srinivasan explains Sarvam’s three-billion-parameter document model, combining block-level OCR with a state-space language backbone. Training progresses from language pretraining through vision, OCR specialization and verifiable rewards. A surrounding harness handles layout and reading order, while a workbench supports human review. The talk emphasizes Indian-language coverage and source fidelity; its leaderboard claims remain reported results.

Zero-click Grok data theft: Cryptographic Context Injection attack leaks chat histories

Adversa demonstrates Cryptographic Context Injection: attacker instructions arrive as AES-encrypted text, the model decrypts them in its code runtime, and the resulting tool output loses its untrusted provenance. The researchers used the chain for Grok chat-data exfiltration and a Gemini policy bypass, while noting that success varies and changed during disclosure.

Building Turbopuffer: Gergely Orosz (@pragmaticengineer ) × Simon Eskildsen (CEO)

Gergely Orosz and Simon Eskildsen discuss the engineering decisions behind Turbopuffer, from dependency failures at Shopify to the economics of search infrastructure. Eskildsen explains using Toxiproxy to exercise real database connections under faults, checking performance assumptions against hardware limits, and combining object storage with faster storage tiers. The conversation connects infrastructure design with product costs and operational experience.
