The HelloFresh meal kit has harnessed AI and modern logistics to field the most impressively gigantic menu I have ever seen. Recipe times are still lies, though.
We're like two model releases away from the harness' prompt getting subsumed into proper RL, thus smoothly allowing the SuperApp (ClaudeWork/CodexGPT) to happen
ITS HERE: xAI’s brand-new standalone Grok iOS app.
Harness powerful AI, generate stunning images, and login with X to personalize your experience with real time news, sports and local data.

As an AI Engineer. Please learn:
- Harness engineering, not just prompt engineering
- Prompt caching vs. semantic caching tradeoffs
- KV cache management at scale
- Speculative decoding vs quantization
- Structured output failures & fallback chains
- Evals (LLM-as-judge + human evals)
- Cost attribution per feature, not just per model
- Agent guardrails & loop budgets
- LLM observability as a first-class discipline
- Model routing & graceful fallback logic
- Knowing when to fine-tune vs. in-context learning
Introducing deepsec, an open source coding security harness.
• CLI-first
• Sandbox-based scaling
• Pluggable coding agents
• Designed for large-scale repos
• Use AI Gateway or your own subscription
After months of successful internal use, we put it to the test on some of the largest open source codebases.
