DeepSeek V4 in Claude Code, Kilo Code, OpenCode: 3-Way AI Verification With GPT-5.5

I never rely on a single AI for code analysis. I wrote about this when I built /consult-codex and /consult-zai - two Claude Code skills that fire parallel queries to Codex GPT-5.5 and ZAI GLM-5.1 for second opinions. That setup caught real bugs that no single model found alone.DeepSeek V4 Pro gave me a reason to expand from two verifiers to three. It has 1M token context, an Anthropic-compatible API endpoint (so Claude Code speaks to it natively), and the pricing is hard to ignore: $0.435 per million input tokens with a 75% promotional discount running until May 31, 2026. That is roughly 4x cheaper than Claude Opus 4.7 for input.So I built /consult-codex-deepseek - a skill that fires Codex GPT-5.5, DeepSeek V4 Pro, and a Sonnet 4.6 code-searcher agent in parallel and gives me a structured 3-way comparison. Three models, three perspectives, one prompt. Eventually, I’ll release this skill in both my Claude Code plugin marketplace centminmod/claude-plugins and in my Claude Code starter…
