  • Gmail plugin AI that learns from my emails?
    I work a sales / client service job for a tutoring company, and I write a lot of emails for it. Most of the emails I receive are pretty similar to others I've received before, and the emails I write are very similar to ones I've written countless times. However, the communications I do are very specific to my industry, so generic autocomplete (such as compose.ai) doesn't produce useful suggestions. Source: about 2 years ago

  • OpenAI o3 and o4-mini – OpenAI
    The big step function here seems to be RL on tool calling. Claude 3.7/3.5 are the only models that seem to be able to handle "pure agent" usecases well (agent in a loop, not in an agentic workflow scaffold[0]). OpenAI has made a bet on reasoning models as the core to a purely agentic loop, but it hasn't worked particularly well yet (in my own tests, though folks have hacked a Claude Code workaround[1]). o3-mini... - Source: Hacker News / 19 days ago
