Thariq’s tests suggest Claude Code’s effort slider mostly changes verification, edge-case testing, and independent judgment—not just response length. Low/medium shine for fast iteration, while high/max can pay off for security, code review, and tricky benchmarks.

Thariq argues MCPs may now beat CLIs for most integrations, citing better tool calling, stateless servers, and deferred tools for progressive disclosure. Others agree the protocol is improving, but warn MCP still needs a REPL-like workflow to truly compete.

Anthropic has just rolled out Claude Fable 5.1 and Claude Mythos 5.1, touting stronger coding and knowledge-work performance. The company also says cache reads and Claude Code sessions are cheaper, with fewer bio- and cyber-safety interruptions.

Addy Osmani says automated code generation still needs humans upstream, where intent, architecture, and quality bars are set. His “software factory” model emphasizes deterministic checks for evidence, with reviews focused on high-risk changes and clear ownership.

OpenAI is pushing model selection and token efficiency as key to cheaper AI agents, citing GPT-5.6 examples from startups. The post highlights routing tactics, prompt caching, and big token cuts with mixed transparency on real-world error rates and latency.
