Perplexity launched Computer, an orchestration-first agent platform featuring multi-model routing, usage-based pricing, and parallel asynchronous sub-agents for distributed workflows. Andrej Karpathy claims a "phase change" in coding agents since December, highlighting sustained long-horizon task completion. OpenAI released GPT-5.3-Codex with ~25% speed improvements and strong benchmark performance, while Claude Code celebrates its first year with ecosystem integrations and scaling challenges. This marks a significant shift in coding workflows and agent-based software development.
