    OpenAI introduced GPT-Live on July 8, 2026 as a new generation of voice models for more natural human-AI interaction. Real-time voice demos make latency visible. Production interfaces also need to make authority visible: who is speaking, who is listening, and what happens after an interruption? - Source: dev.to / about 10 hours ago
  • How to track LLM costs per customer in production
    Provider-side metadata. Both major providers expose per-user tagging. OpenAI accepts a user parameter on the Chat Completions and Responses APIs, and the OpenAI Usage API (launched December 2024) supports group_by=user_id for programmatic per-user cost breakdown. The Costs endpoint requires an admin key. Anthropic accepts metadata.user_id on every API request, capped at 256 characters and explicitly not for PII.... - Source: dev.to / about 1 month ago
  • How I Run 3 Production AI SaaS on $5/Month of Hosting
    For solo founders who don't run their own gateway: use Claude direct for highest quality, OpenAI for proven reliability, or wire up multi-provider routing via something like Prism (or build your own โ€” see Prism's architecture once it's published). - Source: dev.to / about 2 months ago
  • Cursor Just Released Composer 2.5. Here's What Actually Changed for AI Coding Agents.
    Composer 2 originally gained attention because Cursor delivered strong coding performance at dramatically lower token costs than frontier proprietary models. Cursor positioned it as a cheaper alternative to systems from Anthropic and OpenAI. (Cursor). - Source: dev.to / about 2 months ago
  • The Text Field is the New Dashboard
    The most extreme case arrived in April 2026. In 2024, OpenAI CEO Sam Altman predicted that a one-person billion-dollar company "would have been unimaginable without A.I., and now it will happen." He maintained a betting pool with fellow tech CEOs over when it would arrive. In April 2026, he emailed the New York Times claiming he won the bet and that he "would like to meet the guy.". - Source: dev.to / 2 months ago
