Summary A

Claude Code burns 33k tokens before your prompt is read—OpenCode only 7k. This means your per-invocation cost is 4–5× higher with Claude Code, and cold-start latency jumps from ~200 ms to ~1.2 s on the same hardware. If you’re running agents at scale, switching to OpenCode cuts your token budget by 75 % or lets you spin up 4× more parallel instances for the same spend.

Summary A

Structured inference-time control (CogniConsole) cuts failure rates and output variance by up to 40% without touching the model. This means you can ship multi-step agents that actually meet SLAs and stay on-task by swapping ad-hoc prompt engineering for a formal coordination layer—no retraining, just tighter runtime guarantees.

Summary A

GATS achieves 100% success rate on complex planning tasks with zero LLM calls during inference, cutting per-task compute costs to near-zero while eliminating stochastic failures. This means you can ship deterministic, high-reliability agents that scale without ballooning cloud bills or unpredictable rollbacks—critical for production systems where consistency and cost matter more than marginal accuracy gains.

Summary A

The proportion of ChatGPT users aged 35 and older rose to 31% globally, with nearly one in four U.S. smartphone-using parents accessing it, indicating a significant shift towards household adoption; this now requires OpenAI to prioritize trust and safety features, such as parental controls and age-appropriate experiences, to mitigate risks associated with younger users.
