What to Watch

Interpretation, not reported fact. Each point follows from a source listed below — follow the links and judge for yourself.

• Developer adoption may pivot heavily toward agentic efficiency metrics (reduced tool calls and tokens) rather than raw benchmark scores alone. (Basis: Meta AI's focus on 20% fewer tool calls in Muse Spark 1.3 and Firecrawl's 8x reduction in /agent endpoint costs.)
• The transition from legacy voice assistants to full LLM-driven agents will accelerate on consumer operating systems. (Basis: Google's phase-out of Google Assistant in September 2026 in favor of Gemini on Android and Wear OS.)
