Entries
- Day 206 · October 14, 2026AI Self-Replication Research and What It Really ShowsMeta's Muse model family, China's AI chip split, agent-harness open source, and a day-200 look back
- Day 205 · October 13, 2026REA and Agent-Driven Reverse EngineeringMistral Large 4 and open-weight mixture-of-experts, GPT-6 and Haiku 5.5 follow-ups, and why the primary source matters
- Day 204 · October 12, 2026GPT-6 and ChatGPT's Intelligent UIClaude Haiku 5.5 and the economics of cheap models, the US-China compute race, and teen-safety ratings for chatbots
Takeaways of the week
- Limit what agents can reach. Restrict network egress and credentials so a misbehaving agent cannot copy files or itself out. Day 206
- Read headlines for the mechanism. Ask what the agent actually did, in what environment, and who ran the test. Day 206
- Read active, not total, parameters. For MoE models, active parameters drive latency and cost; total parameters drive memory. Day 205
- Wait for the license. Open weights are only useful if the license allows your use; check it before planning a migration. Day 205
- Measure cost per task, not per token. Count tokens used, retries and the effort setting; a cheaper model is not always a cheaper job. Day 204
- Check pricing tiers. Look for context-length thresholds (like 100K) and tokenizer changes before trusting a '75% cheaper' claim. Day 204
