OpenAI is expanding Daybreak into two tiers—Daybreak Blue, which provides trusted defenders access to GPT‑5.6 Sol with tailored safeguards removed to support vulnerability discovery, secure code review, malware analysis, incident response, and patch validation; and Daybreak Red, which provides purpose‑trained cybersecurity models for authorized vulnerability research, exploit validation, and security testing, including the new GPT‑5.6‑Cyber. OpenAI reports GPT‑5.6‑Cyber completes 95.0% of advanced cybersecurity requests on its internal Advanced Cybersecurity Completion Rate (versus 1.5% for GPT‑5.6 Sol and 2.0% for Sol with Daybreak Blue, and 57.3% for GPT‑5.5‑Cyber), outperforms earlier models on ExploitGym and a zero‑day benchmark, but produces shorter vulnerability reports and is less token‑efficient than GPT‑5.6 Sol on ExploitBench under a 300‑turn limit (the gap narrows at 600 turns).

OpenAI cuts GPT-5.6 prices, introduces Fast mode #1 📝 OpenAI News Advancing the price-performance frontier with GPT 5.6 - OpenAI cut GPT‑5.6 prices—Luna is 80% cheaper and Terra 20% cheaper—and introduced Fast mode (replacing Priority Processing) so GPT‑5.6 Sol can run up to 2.5× faster than Standard at 2× the price. The company says model, inference, and agent improvements reduced end‑to‑end serving cost by 20% and improved token‑generation efficiency >15%, with claims that Luna delivers near‑frontier performance at roughly $0.06 per task and nearly 9× the speed (customer benchmarks include Blitzy’s 2.2× more context with 8.5× fewer output tokens at 87% lower cost and Dust’s 40% faster/40% cheaper results).
