Research and Benchmarks

• Test-time compute scaling: Large-scale studies show test-time compute strategies improve complex reasoning without retraining; effectiveness depends on allocation strategy rather than raw compute. (Summary | Paper)
• OPPO FINDER benchmark: OPPO's FINDER benchmark (100 tasks) and DEFT taxonomy reveal agent failures in evidence integration, verification, and planning. (Overview)
• Neel Nanda on interpretability: Nanda argues for studying chain-of-thought in practical interpretability, countering "interpretability failed" hype. (Clarification | Technical)
• Gradium raises $70M seed: Paris-based Gradium exited stealth with a $70M seed round, launching transcription/synthesis APIs supporting 5 European languages. (Announcement | Founder thread)

Agents and Tooling

• LangSmith Agent Builder (beta): No-code agent builder supporting prompts, tools, triggers, MCP, and memory/summarization. (Release | Video)
• LlamaIndex LlamaAgents and LlamaSheets: Workflow templates and spreadsheet parsing, plus community office hours. (Recap | Invite)
• Hugging Face Skills: Universal agent context compatible with Cursor, Claude Code, and Gemini CLI, using Claude's skills specification. (Twitter)
• Perplexity open-sources BrowseSafe: BrowseSafe and BrowseSafe-Bench defend against prompt injection, outperforming safety classifiers. (Announcement)

Community Highlights

Reddit
