Claude Sonnet 4.6 vs GPT 5.3 Codex Same Prompt in Cursor (Neutral Harness) - Default Settings! GPT 5.3 Codex took - 2 mins Claude Sonnet 4.6 - 7 mins Cheaper than Sonnet 4.6! Faster than Sonnet 4.6! But I'm not sure if it's more craftier than Sonnet 4.6 because Sonnet's got a taste! Claude Sonnet 4.6 had a better result (aesthetically) and also more solid techstack - GPT 5.3 codes meanwhile just got the job done!

Claude Opus 4.6 vs GPT-5.3 Codex aren't just different models. They're different engineers. Opus 4.6: → 1M token context window → Reads the whole codebase before deciding → Asks "should we do this?" → Failure mode: overanalyzes, hesitates GPT-5.3 Codex: → 200K tokens, built for speed → Decides fast, acts, iterates → Asks "how fast can I ship this?" → Failure mode: locks in a flawed assumption early Think: Opus = your architect Codex = your operator Pick the one that matches the task.

Opus 4.6 and Codex 5.3 just launched, so I did a hexagon test on both of them Opus 4.6 - 1M context - great for research + enterprise work - agent teams + long-range reasoning - weaker on raw code benchmarks Codex 5.3 - wins coding benchmarks - faster + mid-task steering - smaller context window TLDR: Opus = depth + orchestration Codex = speed + code

GPT-5.3 Codex is actually pretty insane with Three.js This Minecraft clone works smoothly and it didn't take too long to make I also tried Opus 4.6, but for some reason it got stuck

Stop saying that Opus 4.6 is better than Opus 4.8. I just tested Claude Opus 4.8 (Right) and Claude Opus 4.6 (Left) on the same exact prompt. Claude Opus 4.8 completed it in less than 2 minutes. Claude Opus 4.6 "Garnished" for over 7 minutes. Stop using Opus 4.6.

Clone a functional Billion $$ SAAS Part 2 - Figma. Now that Claude Opus 4.6 and Codex 5.3 are available, I decided to try this again. The result - CanvasKit Tools used - Windsurf (retired) Cascade & OpenAI Codex CLI First agent run - 30 minutes Total time spent w/ extra prompting - 3 hours I think this could be a new metric for model evaluations - TTBS (time to billion $$ SAAS 😂) Code and details below:

A behind the scenes look at the level editor: → 1. Set player spawn → 2. Set NPC locations → 3. Adjust navmesh Allows for very quickly integrating new assets into the game. Everything vibe coded... → GPT 5.3 Codex → Opus 4.6 (always use both) You can just make things.

Guys, stop underestimating the harness. GPT-5.6 Sol through Claude Code vs Codex produced a GIGANTIC difference in my benchmark. But Opus 5 is the real innovation: High, xHigh, and Max don’t just feel like different thinking levels—they feel like COMPLETELY DIFFERENT MODELS. It’s basically like getting three or four Opus models in one.

🇵🇱 Dzisiaj stworzyłem Claude Code Math Prover (13-minutowy film pokazuje jak to działa). Claude Code Opus 4.6 orkiestruje cały przepływ pracy. Deleguje podzadania do różnych agentów: - OpenAI Codex 5.3 (badacz, rozwiązuje, recenzent) - jak widać można używać równolegle i Codex'a i Claude Code. - Claude Code (planista, rozwiązuje). - Wykorzystuje MCP poprzez lean-lsp-mcp dowodzenie twierdzeń za pomocą Lean. Używam Team Agents z tmux do pokazania jak Claude Code deleguje zadania do Codex i do siebie ale do subagentów. SKILL - codex - napisałem skilla do orkiestracji Codex'a -------------------- 🇬🇧Claude Code Math Prover (13-minute video) I made today. Claude Code Opus 4.6 orchestrates the workflow. It delegates subtasks to different agents: - OpenAI Codex 5.3 (researcher, solver, reviewer) - so we can use both solution Codex ad Claude Code - Claude Code (planner, solver). - It uses MCP via lean-lsp-mcp, which enables agentic interaction with the Lean theorem prover. I use Claude Code team agents for this task so you can see how Claude Code delegate all task. SKILL - I wrote skill for codex orchestration

Selamlar Dostlar, dün GPT 5.4 yayınlandı ve birçok yüksek benchmark metriğiyle geldi. Bende Cursor'da GPT 5.4-High'ı ve Opus 4.6 High'ı kıyasladım. Detaylı prompt'u yorumlara ekleyeceğim. Gördüğüm en önemli GPT 5.4 coding skills değişiklikleri; - Kodu yazarken oldukça sistematik ilerliyor. Planlamaya otomatik geçiriyor. - Tekte doğru kodu yazma yine sıkıntılı 5.3'de olduğu gibi. Ama bunun önüne test ortamı implementasyonu ile geçmişler. Model kodu yazarken sık sık ek kontroller yapıp kodu düzenliyor. Ama bu fazla token yakmaya neden olabilir! - Python'da otomatik venv ortamı kurup orada işlemlerini yapıp çalıştırıyor. Sonuçlar ve Gemini Pro'nun Analizleri; - Hız: Opus 4.6-High 12:32 dakika'da, GPT 5.4-High 12:40 dakika'da tamamladı. - Toplam Satır: GPT: 1497 vs Opus: 1270 - Class Sayısı: GPT: 14 vs Opus: 13 - Çözünürlük: GPT: 1600×900 vs Opus: 800×600 - FPS: GPT: 120 vs Opus: 60 - Görsel Kalite: GPT: 9.2 / 10 vs Opus: 6.5 / 10 - Ses / Audio: GPT: 8.5 / 10 vs Opus: 7.8 / 10 - Kod Kalitesi: GPT: 9.0 / 10 vs Opus: 7.5 / 10 - Feature Tamamlanma: GPT: 9.5 / 10 vs Opus: 8.0 / 10 - Mimari / Tasarım: GPT: 9.0 / 10 vs Opus: 7.0 / 10
