    I can also stick a fork in my eyeball – but why would I ? Same goes for OSS

      Some companies prefer not to share sensitive information with GPT, so maybe you can sell custom GPT OSS’ to them.

      “We introduce gpt-oss-120b and gpt-oss-20b, two open-weight reasoning models available under the
      Apache 2.0 license and our gpt-oss usage policy. Developed with feedback from the open-source
      community, these *text-only* models are compatible with our Responses API and are designed to
      be used within agentic workflows with strong instruction following, tool use like web search and
      Python code execution, and reasoning capabilities—including the ability to adjust the reasoning
      effort for tasks that don’t require complex reasoning”

    PSA, you don’t need a 5090 to run OSS 20b, just any gpu with 16gb, and LM studio allows for multiple Cuda GPUs to share the load, which means multiple 8gb GPUs can run it. Works with AMD too, just download the right Ollama version for your system.

      PSA I’m running gpt-oss-20b on a 3070 with 8GB and get 8-16 tokens/sec with time to first token typically a couple of seconds and often < 1 second, low reasoning effort. It’s *much* faster and gives better answers than any other model I’ve run locally. My only complaint is about LM Studio…I wish they’d add chat export to PDF.

      @@radish6691 I ran it on my M4 Pro MBP with 48gb of ram, and I was surprised how fast it was. For simple hello world type prompts it was faster than 60 toks/s for slower more complex it went down to 30 toks/s.

      But felt as fast as online ChatGPT.

    It ran 30-60 tokens/sec on my 48gb M4 Pro MacBook Pro. It didn’t feel slow.
    (I’m talking about the 20gb model, couldn’t run the 120gb model with only 48gb of RAM).

    There’s something faster than local AI. A presenter on caffeine (or whatever).

    What is the point of using inferior, error-prone models that require powerful GPU’s to run locally?

Upload vs download speed: which one is actually making your home internet feel slow? If your video calls freeze, your files take forever to sync, or your livestream stutters, the problem is usually your upload speed — and most providers don’t advertise it.

GFiber has kept the same monthly price for gigabit internet since 2012 — no annual contracts, no forced bundles, free installation, and month-to-month flexibility. See what real customers say on the GFiber channel: youtube.com/@GFiber
