Your AI coding costs are trying to tell you something (Sponsor)

The biggest model. Maximum reasoning. Let it run. AI coding costs can climb fast. Simply capping usage can get in the way of productive work. Databricks found much bigger levers: model choice, routing, reasoning effort, context management and smarter guardrails. See what we learned managing AI coding at scale. Keep teams moving without giving AI spend a blank check.

Voxtral 3: Voice Agent SDK & Speech Models in 50+ Languages (7 minute read)

Voxtral 3 offers advanced speech-to-text and text-to-speech capabilities across 50+ languages. Featuring models like Small Transcribe 3 for multilingual transcription and Mini TTS 3 for natural emotional speech, it includes a voice agent SDK combining real-time listening, reasoning, and speaking, enabling seamless interactions and task execution over phone or web.

llm-d (Website)

llm-d is a Kubernetes-native stack for distributed LLM inference. It runs vLLM, SGLang, and more across clusters, turning single-node engines into production-grade serving on local hardware. llm-d provides tested deployment recipes for common production patterns that are adaptable starting points across models, hardware, and workloads. It runs production LLM inference across GPUs, TPUs, XPUs, CPUs, and emerging NPUs with consistent performance patterns, so teams can deploy once and scale anywhere with predictable cost and behavior.

Making every harness durable (7 minute read)

Vercel's durable-harness allows agent harnesses to run durably in the cloud out-of-the-box. It allows users to run Pi, OpenCode, Codex, and Claude Code durably on Vercel or self-hosted on their own Postgres instance. durable-harness ensures that sessions survive crashes mid-turn and keep running even if the browser disconnects. Turns that lose function partway through continue from the log on a new one without manual retry and without repeating what already finished.

Building Laminar: Ramp's Managed Agents Platform (14 minute read)

Laminar is an in-house agent harness for Ramp's agentic products. It features secure conversation history storage, session compaction, standard interfaces for tool calling, message queuing and steering, subagents, multiplayer chat support, observability tooling, and much more. The first version of Laminar was built in six weeks with a small team of obsessive, experienced engineers who worked with and steered the agents. Its code was generated entirely by agents using the most powerful models available at the time. While building in-house has become cheaper, Ramp still needs good engineers to be on-call, keep the platform healthy, and figure out what product teams actually need and how it fits into the bigger picture.

Coxon Day (48 minute read)

On September 8, Jacob Coxon, a 27-year-old machine learning researcher who had resigned from Anthropic, warned the world that AI companies were not acting responsibly and that they were gambling with people's lives by racing straight to self-improving superintelligence. Many researchers seriously believe that AI could kill all humans. While Anthropic may be trying its best, it still doesn't have a plan to solve alignment for superintelligence and is not on track to.
