#Tutorial/How-to

AIAnthropic's Boris Cherny says Claude works best when prompted like a coworker, with a clear goal and no heavy scaffolding. He says prompts now matter most for stating the desired task, the effort level, and how Claude should verify its result, whereas prompts mattered more in the Sonnet 3.5 era.

AIElvis Saravia argues that building good evals on top of AI systems can put a practitioner at the frontier of their domain or task quickly. He advises readers to learn eval construction, calling it worth the investment. The post responds to Garry Tan's point that agents writing markdown skills on cron jobs can handle most knowledge work.

AINVIDIA's technical blog describes bitwise determinism for large-scale pretraining with Megatron Core, which makes training runs easier to debug, validate, and resume reproducibly. The source says these benefits matter most for models with trillions of parameters trained across thousands of GPUs, where multiple parallelism dimensions, low-precision computation, and distributed checkpointing complicate failure reproduction and fix validation.

AINVIDIA's DOCA GPUNetIO lets GPU applications control networking and data movement directly, rather than routing each transaction through the CPU. The source says host-driven network handling adds latency on the critical path and limits how quickly distributed applications can respond in real time. The provided text is truncated, so details of the unified software stack are not available.

AILangChain is promoting a LangChain Academy course that teaches developers how to build long-running agents for complex workflows using Deep Agents. The post links to the course page and invites readers to enroll today.

AIAnthropic's ClaudeDevs says Claude Code cloud sessions run each task on a fresh VM, so users can start several at once. The sessions keep running after the user closes their laptop. A field guide covers seven suitable workflows and how to connect GitHub.

AIDex Horthy (@dexhorthy) announced episode #77 of his AI That Works series, titled "Building a Memory Pipeline," as a live broadcast. The post provides no further technical details about the pipeline's design, tools, or results.

AIAllie K. Miller suggests giving an AI agent a separate email address, which Instinct does automatically, and using it for junk signups so the agent filters that mail away from your main inbox. She compares it to Google Voice for email and argues retail emails will get less attention unless they give people a reason to reach the human inbox.

AIxAI has shared a complete cookbook repository on GitHub, linked at The post gives no further details about the repository's contents or purpose.

AIBoris Cherny, who works at Anthropic, said he asked Opus 5.5 to build an interactive website companion for the latest Acquired episode on Home Depot. He noted that the watercolor illustrations on the site were also drawn by Claude.

AILangChain's Sydney Runkle presents a four-step method for building a model router into a coding agent harness: understanding tasks, understanding models, building the router, and tracking task outcomes. The background post says the router cut costs by 64% without reducing quality by sending tasks that do not need a frontier model to cheaper models.

AILauren Tan describes using Grok Bot to connect apps like Slack, email, and CRM so it can gather context and decide what work to do. She also explains scheduled and event-triggered routines, plus handing engineering tasks to Cursor cloud agents, with a daily feedback-to-merge loop example.

AIReplit announced a livestream titled "Building a Viral Growth Engine," part of its Pro Series. The post provides no further details about the content or speakers.

AIGoogle Flow Music lets creators build custom instruments or effects from natural language, and Spaces can now be exported as VST3/AU plugins. These plugins run inside producers' Digital Audio Workstations, so tools can fit existing production workflows. The source gives producer Khris Riddick-Tynes's "No Chaser" plugin as an example for checking instrumentals and vocals.

AIDex Horthy reports that /show-me has been incorporated into the official Amp Code plugins. A linked GitHub pull request in the ampcode/official-plugins repository is referenced as the relevant change.

AIKilo (@kilocode) posts a link to a video walkthrough on YouTube. The post provides no further details about the product or features shown.

AIGeorgi Gerganov says users of Qwen3.8-27B with MTP can get extra speed by switching to DFlash speculative decoding in llama.cpp. The command uses --spec-type draft-dflash with --spec-draft-n-max 7, and it requires the latest llama.cpp v0.6.0.

AIThe post shares a YouTube video offering a guide to launching on Product Hunt and achieving top rankings. It gives no specific tactics, figures, or product details beyond the video link.

AIJump Trading is using OpenAI to expand its quantitative research, with longer-running AI workflows that combine multiple data sources alongside human review. The source does not give further details on specific models, metrics, or results.

AIConversation intelligence records and transcribes sales and support calls, then uses AI to tag sentiment, objections, and action items for team-wide review. The guide explains how the pipeline works, from data capture and transcription to analysis and CRM sync. It also outlines benefits such as faster coaching and less manual data entry.

AIThe article explains how to write AI video prompts that produce authentic claymation and stop-motion looks without physical sculpting or frame-by-frame photography. It stresses specifying material properties such as polymer clay with visible thumbprints, movement rhythm such as a 12fps animation feel, and negative prompts such as "no photorealism" to suppress glossy 3D defaults. It also includes 15 example prompts organized by material, texture, and category.

AIThe guide gives a prompt formula for AI tattoo designs: Subject + Style + Composition/Placement + Detail Level + Color + Mood. It says geometric and dotwork styles produce strong AI results, and that placement-specific wording, such as "small wrist tattoo" or "full sleeve design," helps set appropriate detail. It also recommends changing one variable at a time when refining prompts.

AIComcast and Booz Allen used Claude Mythos Preview to find vulnerabilities that arise from interactions across code, configuration, and deployment rather than single-file bugs. Comcast identified a critical authentication flaw across 258 systems and about 170 million lines of code before any exploitation was observed. Booz Allen reported that one analyst reviewed eight production systems across 138 repositories in twelve days, a review its team estimated would have taken several months without the model.

Why it matters: The case studies show how security teams validate and remediate model-found exploit chains, a workflow relevant to anyone managing large codebases.
