## Worth attention

- **GPT 5.6 Sol, Luna, and Terra now available on AI Gateway**
  https://vercel.com/changelog/gpt-5-6-now-available-on-ai-gateway
  OpenAI's GPT 5.6 is in limited preview on Vercel AI Gateway in three variants: Sol (flagship), Terra (claimed previous-gen performance at half the cost), and Luna (fastest, cheapest). Provider pricing with no markup, and routing rules let you switch models without code changes. If any agent workloads run on GPT-5-class models, Terra's half-cost parity claim is a direct cost lever worth benchmarking.
- **EU AI Act Article 50: machine-readable disclosure for AI content starts August 2026**
  https://www.reddit.com/r/SaaS/comments/1usdqev/founders_producingusing_ai_generated_content_how/
  EU AI Act Article 50 transparency obligations begin applying in August 2026: AI-generated content (text, images, video, audio) reaching EU users must carry a machine-readable disclosure signal, not just a visible caption or watermark. Founders are already debating C2PA Content Credentials and the gap where metadata gets stripped on screenshot or reupload. Any solo builder whose products or marketing pipelines emit AI-generated content to EU users should decide on a disclosure approach now.
- **[AINews] OpenAI launches GPT 5.6 Sol/Terra/Luna, Codex becomes ChatGPT superapp**
  https://www.latent.space/p/ainews-openai-launches-gpt-56-solterraluna
  Latent.space's AINews roundup of the GPT 5.6 launch: three variants (Sol, Terra, Luna) plus OpenAI repositioning Codex as a ChatGPT 'superapp'. Useful for ecosystem reaction and the Codex strategy angle; the practical availability details are covered by the AI Gateway changelog item.
- **Vibe-coding a launch video with Remotion**
  https://www.reddit.com/r/SaaS/comments/1urq5kq/turns_out_you_can_vibe_code_a_launch_video_and/
  A builder coded an agency-quality product launch video using Remotion, the open-source React video library, instead of paying thousands for an agency. Because it renders from your own React components, the motion design matches your actual brand rather than a template, and it's free. Worth remembering next time a project needs a demo or launch asset.
- **Build logs now redact Sensitive Environment Variable values**
  https://vercel.com/changelog/build-logs-now-redact-sensitive-environment-variable-values
  Vercel now replaces Sensitive Environment Variable values 32 characters or longer with [REDACTED] in deployment build logs, logs the redaction event (key, project, deployment — never the value) to the Activity Log, and also redacts selected system env vars. Closes a common secrets-leak path; only action is to mark long-lived secrets as Sensitive so they get the protection.
- **Muse Spark 1.1 is now available on AI Gateway**
  https://vercel.com/changelog/muse-spark-1-1-is-now-available-on-ai-gateway
  Meta's Muse Spark 1.1 is on Vercel AI Gateway: a multimodal reasoning model with a 1M-token context window built for agentic tasks, supporting parallel tool calling, structured output, and — notably — claimed zero-shot use of new tools, MCP servers, and custom skills. Provider pricing, no markup. A candidate to benchmark for MCP-heavy agent orchestration.
- **Profiling in PyTorch (Part 3): Attention is all you profile**
  https://huggingface.co/blog/torch-attention-profile
  Part 3 of Hugging Face's PyTorch profiling series, focused on profiling attention kernels. Solid reference material for anyone tuning local inference performance beyond stock Ollama defaults; skip otherwise.
