⚡️GPT 4.1: The New OpenAI Workhorse

Michelle Pokrass returns, with Josh McGrath to talk about the new GPT 4.1 model

We’ll keep this brief because we’re on a tight turnaround: GPT 4.1, previously known as the Quasar and Optimus models, is now live as the natural update for 4o/4o-mini (and the research preview of GPT 4.5). Though it is a general purpose model family, the headline features are:

• Coding abilities (o1-level SWEBench and SWELancer, but ok Aider)

• Instruction Following (with a very notable prompting guide)

• Long Context up to 1m tokens (with new MRCR and Graphwalk benchmarks)

• Vision (simply o1 level)

• Cheaper Pricing (cheaper than 4o, greatly improved prompt caching savings)

We caught up with returning guest Michelle Pokrass and Josh McGrath to get more detail on each!
