OpenAI launches GPT-5.6 family with Sol, Terra, Luna models
OpenAI announced the general availability of the GPT-5.6 family, including flagship model Sol, balanced model Terra, and cost-efficient Luna. Sol achieves state-of-the-art results across coding, knowledge work, cybersecurity, and science, outperforming previous frontier models with fewer tokens and lower cost per dollar. Pricing ranges from $1/$6 per million tokens for Luna to $5/$30 for Sol. The models have a million-token context window and a February 2026 knowledge cutoff.

2026 survey finds enterprise AI agent pilot-to-production rates as low as 5%
A 2026 survey of enterprise AI agent deployments found that only 5% to 23% of pilots reach production, with the model itself rarely being the cause of failure. The findings highlight persistent challenges in operationalizing AI agents beyond proof-of-concept stages.
Developer seeks prompt caching optimization for GitHub Copilot Agent Mode with GPT-5.6
A developer is trying to optimize prompts for GitHub Copilot Agent Mode, noting that GPT-5.6 models make prompt caching more valuable due to specific Cache Read and Write costs. They reference OpenAI's API documentation for prompt caching (1024-token prefix, 128-token increments, identical prefix matching, short-lived in-memory caches, optional 24-hour extended caches) but cannot find whether GitHub Copilot exposes the same behavior or has its own orchestration layer.
