Coding Agents

An end-to-end tutorial for engineers shipping long-running coding agents in production. We build a TypeScript queue on Bun that submits agent jobs to Mistral Le Chat Work mode and OpenAI background mode, polls or receives webhooks for completion, enforces per-job cost ceilings, and exposes a small status dashboard — the operating model behind the new async-coding paradigm.

A practical, end-to-end migration guide for engineers running production coding agents on GPT-5 who want to evaluate or move to DeepSeek V4 — the open-source frontier model that landed Friday claiming the strongest agentic coding scores in the open ecosystem. Covers API differences, tool-calling adaptation, streaming, the agent loop, evaluation, and the real cost math.

Major tech companies are rolling out sophisticated AI agents that act as real-time pair programmers, fundamentally changing how software is created. This analysis explores developments from IBM, AWS, Google, and OpenAI, and what they mean for developers.
