Anthropic's new API version brings major SDK bumps and a switch to Apache 2.0, Claude Code adds a Linux user-namespace sandbox with a setting worth handling carefully, Codex CLI turns on mid-response steering, and Claude Duet debuts. We teach semantic versioning and what a sandbox and namespaces actually are. Hosts: Alex & Jules. New episodes daily.

Claude Code adds idle compaction for long sessions, Mistral releases Timestral time-series models that run on a CPU, plus a tmux guide for driving agents, the case for running your own LLM proxy, and a paper on latent-space reasoning agents. We teach context windows and compaction, and what latent reasoning means. Hosts: Alex & Jules. New episodes daily.

Cursor's cloud agents can now build shareable canvases, and a new Environments API lets you script agent setup. We also cover Claude Code turning fork subagents on by default, the removed remote-control sandbox flags, and Cursor's Origin app marketplace. Concept of the day: local agents vs cloud agents, and why the environment matters. Hosts: Alex & Jules. New episodes daily.

Claude Code now compacts long idle conversations before the prompt cache expires, and we explain what compaction is and why timing matters. Plus Cursor cloud agent canvases and 300-repo environments, Codex CLI mid-response steering, and Antigravity CLI's new Auto mode. Hosts: Alex & Jules. New episodes daily.

Gemini 4 Argon lands on Hacker News with a benchmark table that wins some and loses some, Timescale's alpha pg_vectorsearch promises HNSW-beating vector search at a quarter of the memory, and a TV4 data-loss story becomes a lesson in agent permissions. We teach two concepts today: context windows and vector quantization. Hosts: Alex & Jules. New episodes daily.

Claude Code now compacts big idle sessions before the prompt cache expires, MCP's stateless 2026-07-28 protocol becomes the default, and Cursor opens its Origin App Marketplace. We teach what prompt caching and stateless servers actually are, plus a quick lap of Gemini, Copilot and Antigravity CLI updates. Hosts: Alex & Jules. New episodes daily.

Claude Code hooks can now block actions when they fail, Haiku 5.5 becomes the default with a 1M-token context window, and compaction bugs get fixed. We also teach what a context window and compaction actually are, plus a roundup of Copilot, Codex, Antigravity and Kiro CLI updates. Hosts: Alex & Jules. New episodes daily.

Claude Code ships a batch of permission-bypass fixes, Underdog's 8 GB Saluki 27B shows what 2-bit quantization buys and costs, and llama.cpp's new Metal kernels speed up speculative decoding on Apple Silicon. We also cover Google ending new Gemini Code Assist sales in favor of Antigravity. Concepts taught: quantization and speculative decoding. Hosts: Alex & Jules. New episodes daily.

Claude Haiku 5.5 arrives with a 1M-token window and low pricing, Claude Code adds fail-closed hooks, Codex CLI gains managed Git worktrees, and Copilot CLI and Antigravity CLI ship sandbox and plugin updates. Today's concepts: what a token is (and why price per token isn't the whole bill) and fail-open vs fail-closed security. Hosts: Alex & Jules. New episodes daily.

Mistral Large 4 enters public preview, OpenAI's Decisions API returns probabilities instead of prose, and Google's EmbeddingGemma 2 puts text, code, images and audio in one search space. We also cover Claude Code 2.1.292 and Codemode, and teach what embeddings are and how Matryoshka truncation works. Hosts: Alex & Jules. New episodes daily.
