GPT-5.3-Codex vs Codex-Spark vs Claude Opus 4.6 vs Gemini 3 Pro: What to Choose a Wibcoder in February 2026
Main chat
A chat for vibe coders: news, guides, live cases, marketplace, and finding executors.
Over the past two weeks (February 5-17, 2026), four models have been released at once, which completely changed the rules of the game in AI coding.
I tested them on real projects (Telegram-bots, Next.js-applications, legacy-code refactoring, agent tasks) and collected all the current benchmarks, prices and recommendations for the Vibcoder
Brief comparison table (February 2026, real data)
| Параметр | GPT-5.3-Codex | Codex-Spark | Claude Opus 4.6 | Gemini 3 Pro (Google) |
|---|---|---|---|---|
| Дата релиза | 5 февраля 2026 | 12 февраля 2026 | 5 февраля 2026 | 10–12 февраля 2026 |
| Скорость генерации | 65–80 токенов/сек | 1000+ токенов/сек | 40–60 токенов/сек | 120–180 токенов/сек (Flash-вариант до 300+) |
| Контекст | 200k | 128k | 1M токенов | 2M токенов (самый большой) |
| SWE-Bench Pro / Verified | 56.8% / ~74.9% | ~56% (но в 3–5× быстрее) | 80.8% / 75.6–76.8% (лидер) | 75.8% (Gemini 3 Flash) |
| Terminal-Bench 2.0 | 77.3% (лидер) | Высокая скорость | 65–68% | ~72–74% |
| Цена (input/output за 1M) | ~$3–5 / $15–20 | Входит в Pro | $5 / $25 | $1.25 / $10 (самая выгодная среди топов) |
| Лучше всего для | Агентные задачи, полный цикл разработки, bug-fixing | Live-редактирование, быстрые правки в IDE | Глубокое планирование, большие репозитории, code review | Мультимодал, огромные проекты, Google-экосистема, скорость+качество |
| Интеграции | Codex App, GitHub Copilot, Cursor, VS Code | Только Codex (app/CLI) | Claude.ai, Cursor, API | Google Workspace, Vertex AI, Cursor, Gemini Code Assist |

1. GPT-5.3-Codex - "A colleague who does all the work himself"
First real agent. Takes the task “do SaaS-landing with payment” and brings to the deploit. Pluses: Best of all fixes bugs, perfectly understands the context. *Minuses: are more expensive when working long hours.
2. Codex-Spark - "Lightning in Real Time"
1000+ tokens/sec – write “make the button more beautiful” and see the result instantly. Ideal for Cursor/Codex App. Minus: weaker in supercomplex architecture.
3 Claude Opus 4.6 - "The Smartest and Most Careful Engineer"
The King of Quality and Code Review. 1M context is the entire monolith in one window. Pluses: Less hallucinations, better planning. Minuses: slower than Spark and more expensive on very long sessions.
4. Gemini 3 Pro – Google’s Multimodal Sprinter
The most underrated competitor of February 2026. 2 million context tokens + excellent multimodality (pictures, video, PDF) + the best price among the top 4.
Pluses for Vibcoder:
- Huge context – the entire project + documentation is placed
- Faster Opus and Codex for most tasks
- It works perfectly with Google tools (if you use Firebase, Vertex AI, etc.)
- Excellent price/quality balance
*Minuses: Sometimes slightly weaker than Claude on very complex tasks.
What to Choose (February 2026 Recommendations)
** Fast vibcoding* * Codex-Spark (90% of tasks in seconds)
Average level, 1-2 projects per week GPT-5.3-Codex (main) + Spark for editing
Big serious projects, monoliths >50 files Claude Opus 4.6 or Gemini 3 Pro
Ideal stack of most 2026 Vibcoders (my personal):
- Main article: GPT-5.3-Codex
- Quick edits - Codex-Spark
- Deep refactoring and large repositories – Claude Opus 4.6 + Gemini 3 Pro
Who won in February 2026?
- ** Quality and reliability Claude Opus 4.6
- **Speed and high - Codex-Spark
- In terms of universality and agency** - GPT-5.3-Codex
- Price + huge context + multimodal - Gemini 3 Pro
