Claude Sonnet 4.5 - The New Coding King? (Sonnet 4.5 vs. GPT 5 Codex)
Anthropic has just released Claude Sonnet 4.5 and it's a BEAST! Definitely looking like it's the new coding king - at least according to the benchmarks. It's a laser focused LLM (super fast) that simply gets the job done. But I want hands on testing to know if Claude Sonnet 4.5 is truly the best in practice. So in this video, I do a live comparison building out a complex feature with Sonnet 4.5 in Claude Code and GPT 5 Codex in Codex at the same time. Anthropic/OpenAI are not sponsoring this video - results and opinions from my testing are genuine! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - If you're looking to join a community for early AI adopters to master AI Coding & AI Agents and transform your career or business, check out Dynamous: https://dynamous.ai ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 00:00 - Introducing Claude Sonnet 4.5 01:49 - Claude Sonnet 4.5 vs. GPT 5 Codex 03:40 - Running Codex and Claude Code in Parallel 04:38 - Codex vs. Claude Code Mid Execution 05:44 - Results of Claude Sonnet 4.5 08:17 - Results of GPT 5 Codex 10:52 - Final Thoughts ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Join me as I push the limits of what is possible with AI.
