Slack Makes Code API Generally Available

Oct 29, 2026
The Slack Code API lets developers build agents that create dedicated code channels, share progress, involve teammates, and archive the channels when work ends.

Slack made the Slack Code API generally available, the company detailed in a blog post. Developers can now build agents that create dedicated code channels, add relevant people and files, post progress updates, and archive channels after completing a task.

Code channels let teammates review an agent's work, provide context, and approve changes inside Slack. Agents inherit the permissions and admin controls of the channel where they operate. Slack said more than 150 customers and partners had asked to build code channel experiences for their own agents since Slack Code launched in August with partners including Anthropic, Cognition, GitHub and Vercel. Slack said GitHub Copilot opens a dedicated code channel in 30% of its agent sessions.

Slack also plans to add pull request features that let users request GitHub reviews, synchronize comments between Slack and GitHub, and merge approved changes from a code channel. An enhanced Agents & Tools tab will provide a combined view of agent conversations and code channels.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
