DeepSeek dropped a new snapshot of its open-weight V4.1-Flash today, and the headline is the price: about 15 cents per million input tokens and 60 cents per million output tokens on OpenRouter for a 1-million-token context window.
V4.1-Flash is a 552-billion-parameter MoE backbone with 763 billion parameters in the published weights, of which only about 8 billion fire while reading your prompt and 16 billion while writing a response. That asymmetry is the trick: cheaper to absorb long context, more brain for generation. Weights remain MIT licensed.
DeepSeek's own benchmark table puts the 1017 snapshot ahead of its predecessor on most tasks but still well behind Opus 5 on the two hardest reasoning tests (HLE 42.6 vs 56.3, Terminal-Bench 42.3 vs 51.8). Treat "on par with Opus" claims from X as vibes, not data.

Two critical PHP remote code execution flaws — one found by GPT-5.6 Sol — were patched on October 21, 2026, and OpenAI published a disclosure framework alongside the fix. Fixed versions: PHP 8.5.12, 8.4.27, 8.3.36 and 8.2.35. Both allow unauthenticated remote code execution, and PHP's advisory says risk is highest for mod_php, where a demonstrated exploit triggers before any application code runs. The CVEs are distinct failure modes. CVE-2026-109618 (OOM corruption): out-of-memory handling can interrupt PHP while internal request data is only partially initialized, and request cleanup may then treat the invalid data as valid. CVE-2026-109619 (stale global state): request-owned internal state can survive after its backing memory is freed, and a later request served by the same worker may use that stale state. OpenAI states GPT-5.6 Sol identified the first flaw through its Patch the Planet initiative, and that Wiz independently discovered and reported both vulnerabilities. PHP's maintainers led the fixes and release, with Wiz, Cloudflare and OpenAI contributing research and coordination. Wiz's write-up adds that it used GPT-5.6 Sol and Gemini 4 Argon throughout, with Gemini 4 Argon contributing to finding the vulnerability and validating the patch. OpenAI describes the gap between discovery and public exploitation as a "Defender's Window," proposes a five-stage response framework, and committed $1 billion in subsidised Daybreak model access for organizations with limited security resources. Honest caveats: these are OpenAI's and Wiz's own characterizations, and OpenAI also notes the same capabilities help attackers build offensive tooling faster. PHP 8.1 and older no longer receive updates from the PHP project.
