## Worth attention

- **Trace and debug eve agent sessions with Vercel Observability**
  https://vercel.com/changelog/eve-agent-observability
  Vercel now auto-surfaces agent observability for projects using the open-source eve agent framework: an Agent Runs tab shows trigger, duration, and token usage per session, with drill-down into individual runs. Agent tracing and token visibility directly affect anyone building and debugging LLM agents—the kind of observability that changes how you diagnose and cost-control agent workflows.
- **[AINews] OpenAI GPT-5.6 Sol / Terra / Luna — restricted to trusted partners**
  https://www.latent.space/p/ainews-openai-gpt-56-sol-terra-luna
  AINews reports OpenAI shipped a tiered GPT-5.6 family (Sol/Terra/Luna) restricted to trusted partners, oddly coinciding with an Anthropic release the same day. Signals where the frontier-model landscape is heading, but access is gated so there's nothing to act on yet—watch for general availability.
- **Query Web Analytics from the Vercel CLI**
  https://vercel.com/changelog/query-web-analytics-from-the-vercel-cli
  Vercel added the ability to query Web Analytics (page views, visitors, custom events) directly from the Vercel CLI, making traffic data scriptable for trend analysis and automation. Concrete and immediately useful if you host on Vercel; narrow otherwise.
- **How I reach $5k MRR in 2 months. What worked and didn't.**
  https://www.reddit.com/r/SaaS/comments/1ug5ch6/how_i_reach_5k_mrr_in_2_months_what_worked_and/
  A solo founder reports reaching $5k MRR in two months on a B2C app competing against a category leader, with a breakdown of what worked and what didn't. Useful as a concrete, recent data point on early B2C growth tactics for a one-person shop, though it's self-reported and unverified.
- **Anatomy of a Failed (Nation-State?) Attack**
  https://grack.com/blog/2026/06/25/dissecting-a-failed-nation-state-attack/
  A developer dissects a failed, apparently nation-state-grade attack against their infrastructure, walking through the attempt and what stopped it. A useful real-world security read for hardening instincts, though more educational than immediately actionable.
- **Anyone else surprised how fast AI costs add up?**
  https://www.reddit.com/r/SaaS/comments/1ugud65/anyone_else_surprised_how_fast_ai_costs_add_up/
  A discussion thread where founders running GPT/Claude in production compare how quickly inference costs scale once AI features gain usage. No hard numbers, but it tracks a recurring concern—AI cost control—that directly affects anyone shipping LLM features. Worth monitoring as a theme rather than acting on.

## Full digest
