Cody by sourcegraph give you access to both inside vscode for $9/month with unlimited prompts. There is also other one like Phind or Cursor that gives access to both. Opus and GPT4 are pretty similar from my experience, but sometimes one will succeed where the other fail. Answer from debian3 on reddit.com

r/ChatGPTCoding on Reddit: Does Anthropic still have the best coding models or do you think OpenAI has closed the gap?
August 22, 2025 -

GPT-5 (Minimal) was performing quite well early on and even took the top spot for a moment but has dropped to #5 in the ranking on Design Arena (preference-based benchmark for evaluating LLMs on UI/UX and frontend).

Right now, the 6 of Anthropic's models are all in the top 10. In my experience, I haven't found GPT-5 to be clearly better at frontend tasks then Sonnet 4 or I've found it to be personally worse than Opus.

What has been your experience? To me, it still seems like Anthropic is producing the best coding models.

August 8, 2025 - The second is an incremental upgrade to Claude Opus with 4.1. The upgraded model scores a 74.5% on the software engineering SWE test vs 72% for Opus 4. Yesterday, OpenAI unveiled its latest GPT-5 model and it scores 74.9% on the SWE test, up from o3’s 69.1%. GPT-5 comes with some impressive vibe coding abilities and OpenAI has published a gallery of apps you can explore. You can read more about the new model’s coding capabilities here. Anthropic and OpenAI are essentially neck and neck with barely a decimal between them but according to new analysis, Anthropic is in a pretty risky position with almost~50% of Anthropic’s API revenue coming from just 2 customers: GitHub Copilot and Cursor.

r/singularity on Reddit: Do you think Anthropic is ahead of OpenAI. Or is OpenAI waiting to release a big model?
June 24, 2024 -

I am genuinely curious on how many here believe OpenAI is hiding a big model so they can use it when they feel threatened or if they need permission from the government because of how big it is.

But with Claude 3.5 Sonnet, it makes me think that OpenAI may be the Hare in the Tortoise and the Hare fable. They acted all tough and went blazing fast initially but got cocky from winning so much they failed to keep up.

So what are your guys views?
