New in Lex: GPT-5 is live in Lex Pro
Hey! Nathan here, founder of Lex, with a really exciting update!
OpenAI dropped GPT-5 today, and it’s available now in Lex Pro. Here’s what to expect:
- smarter - tested extremely well against industry benchmarks for reasoning. This means it’ll do a better job using context and catching ideas you missed.
- truer - the hallucination rate is much lower. More frequently it’ll disagree or say "I don't know" instead of making stuff up.
- vibe-ier - as intelligent as AI has become, it still often sounds artificial. GPT-5 has a noticeably more natural voice.
If you don’t have Lex Pro but want to give GPT-5 a try today, sign up now for a free 7-day trial!
While GPT-5 is the real heavy hitter, it’s not the only model OpenAI just released.
GPT-5-mini (Lex Pro): Crazy fast, smart enough for most tasks, and doesn't fall into the reasoning model trap of overthinking simple requests. Great for drafting ideas and quick (but still smart!) reviews.
GPT-5-nano (offered to Lex's free tier): Shockingly capable for a less powerful model. If you've been using the free version of Lex, this should be a big upgrade.
These models are brand new, so our opinions are still forming. We're excited to keep testing, and can't wait to hear what you think.

That’s it for today — happy writing!
Nathan
