Code Mode: give agents an entire API in 1,000 tokens

Model Context Protocol (MCP) has become the standard way for AI agents to use external tools. But there is a tension at its core: agents need many tools to do useful work, yet every tool added fills the model's context window, leaving less room for the actual task.

Code Mode is a technique we first introduced for reducing context window usage during agent tool use. Instead of describing every operation as a separate tool, let the model write code against a typed SDK and execute the code safely in a Dynamic Worker Loader. The code acts as a compact plan. The model can explore tool operations, compose multiple calls, and return just the data it needs. Anthropic independently explored the same pattern in their Code Execution with MCP post.

Today we are introducing a new MCP server for the entire Cloudflare API — from DNS and Zero Trust to Workers and R2 — that uses Code Mode. With just two tools, search() and execute(), the server is able to provide access to the entire Cloudflare API over MCP, while consuming only around 1,000 tokens. The footprint stays fixed, no matter how many API endpoints exist.

For a large API like Continue reading

Packet Trimming Deep Dive – Part I

 Introduction


The previous chapter introduced the Ultra Ethernet (UE) Transport Layer and its endpoint-centric congestion control mechanisms: Network Signaled Congestion Control (NSCC) and Receiver Credit-based Congestion Control (RCCC). This chapter moves down to the UE Network Layer and introduces Packet Trimming (PT).

While node-based approaches rely on NIC-to-NIC feedback loops, Packet Trimming allows network switches to actively intervene during periods of high utilization. Instead of silently dropping packets under congestion, the network provides an explicit and fast signal that enables immediate recovery.

The primary goal of Packet Trimming is to prevent incast congestion, a situation in which multiple ingress ports simultaneously overwhelm a single egress port. In AI and HPC workloads, many-to-one traffic patterns are common—for example, when multiple workers send data to a single parameter server. Under these conditions, egress buffers can be exhausted very quickly. In a best-effort network, this typically results in tail drops. The receiver then waits for a retransmission timeout, which introduces long tail latency and disrupts synchronization across distributed workloads. Packet Trimming replaces this silent packet loss with an explicit congestion signal that travels faster than the data itself.

The process begins at the source UE node. The NIC marks outgoing data packets with Continue reading

Taalas Etches AI Models Onto Transistors To Rocket Boost Inference

Adding big blocks of SRAM to collections of AI tensor engines, or better still, a waferscale collection of such engines, turbocharges AI inference, as has been shown time and again by AI upstarts Cerebras Systems, SambaNova Systems (which Intel is rumored to have taken a run at late last year), Groq (just eaten by Nvidia for $20 billion), and Graphcore (eaten by SoftBank for $600 million a year and a half ago) as they compare against GPUs from Nvidia and AMD. …

Metabolisme Bakteri vs Virus: Perbedaan, Dampak, dan Cara Hidup

Pengantar Perbedaan Bakteri dan Virus

Bakteri dan virus sering disamakan karena sama-sama mikroskopis. Namun, keduanya memiliki perbedaan metabolisme yang sangat mendasar. Oleh karena itu, pemahaman ini menjadi penting dalam biologi, kedokteran, dan kesehatan masyarakat. Selain itu, perbedaan metabolisme juga memengaruhi cara pengobatan dan pencegahan penyakit. Dengan memahami konsep ini, kita dapat menentukan strategi penanganan infeksi secara tepat. Selanjutnya, artikel ini membahas perbedaan tersebut secara rinci, sistematis, dan mudah dipahami.

Pengertian Metabolisme dalam Biologi

Metabolisme adalah seluruh reaksi kimia yang terjadi dalam makhluk hidup. Proses ini mendukung pertumbuhan, reproduksi, dan kelangsungan hidup. Selain itu, metabolisme mencakup anabolisme dan katabolisme. Anabolisme membangun molekul kompleks. Sebaliknya, katabolisme memecah molekul untuk menghasilkan energi. Dengan demikian, metabolisme menjadi ciri utama kehidupan sejati. Oleh karena itu, perbedaan metabolisme menegaskan perbedaan tingkat kehidupan bakteri dan virus.

Metabolisme pada Bakteri

Bakteri merupakan organisme prokariotik yang hidup mandiri. Oleh sebab itu, bakteri memiliki sistem metabolisme lengkap. Bakteri mampu menghasilkan energi sendiri. Selain itu, bakteri dapat melakukan respirasi aerob atau anaerob. Continue reading
