Alibaba bans Claude Code company-wide over data exfiltration risk

• Claude Code read user timezone and proxy, matched against 147 China-related domains, and embedded results as invisible Unicode in system prompts.
• Anthropic admitted it was an experiment against distillation and removed the code on July 1.
• The detection was easily bypassed, affecting legitimate developers using proxies.

Fable excels at multi-sheet PCB design over Opus

• Fable handles up to 8 sheets of schematics coherently, while Opus struggles beyond 2 sheets.
• Fable's strength is not raw intelligence but ability to maintain broader context.
• User observed Fable making fewer silly guesses on cross-sheet dependencies.

Phone scan creates photoreal 3D walkthrough for $200

▶

• Cost per scan ~$200 vs $15k agent fee.
• File size smaller than a TikTok clip.
• Freelancers charge $300-$800 per scan.

Prefill speed dominates agentic workloads; KV head count beats parameter count

• Benchmarked 13 models on RX 7900 XT with llama.cpp at context sizes up to 131K.
• Trinity-Mini (MoE 3B/26B) achieved highest prefill speed at 131K (923 tok/s) and highest decode speed (150 tok/s).
• KV cache quantization (Q8_0 K/Q8_0 V) provides good balance; prefill speed drops significantly at long context for many models.

AI web developer strategy: build demo first, then cold-call

▶

• Find local businesses with good reviews but poor websites on Google Maps.
• Use Claude 3.5 to generate website copy from business info.
• Use an AI site builder to create a functional website in minutes.

Restored Roman Empire footage with AI video workflow

❝ This is actually really well done. One of the first historical AI videos I've seen that doesn't show everything already in ruins, or completely without color. ❞

• Avoids showing everything in ruins or without color.
• Uses AI to generate realistic historical scenes.

Ship an agent SaaS in 30 days: niche workflow, shadow, pilot, productize

• Start with a workflow that already carries a paycheck: high frequency, clear finish line, existing software, learnable edge cases, and felt pain.
• Shadow a human across 10–20 real jobs before writing a single prompt.
• Sell the pilot like labor, then productize the repeatable parts into a SaaS wrapper.

Built Tipper: on-chain tipping app on LUKSO using multi-model LLM orchestration

▶

• Used Fable 5 as orchestrator to plan, decompose, route, and synthesize tasks.
• Leveraged Opus 4.8 for deep architecture and debugging, Sonnet 5 for fast implementation, and Codex for cross-model verification.
• Built Tipper with LUKSO standards: tips ride in transaction data, no backend, no database, no custodial contract.
