Open LLMs: Transparency or 'Openwashing'?

philsiarri • 0 implied HN points • 03 Dec 24
🕹 Technology Open Source
  1. Just sharing the source code for large language models (LLMs) doesn't make them truly open. Access to the training data is still needed for real transparency.
  2. Many LLMs limit users by only allowing access to APIs instead of the full model. This practice is being called 'openwashing', where companies give a false impression of openness.
  3. Users often struggle to re-use or adapt the shared code due to how it's written and lack of resources. True openness includes access to hardware, datasets, and original training data.

  2. Compute and electricity are limited, so open-source efforts must focus on making models much more efficient so they can run on everyday hardware instead of only on expensive GPU farms.
  3. Open source AI decentralizes power by breaking corporate and state monopolies, while transparency and local processing let creators keep more value from their own data.

@adlrocha - Open Source is Dead. Long Live Open Execution

@adlrocha Weekly Newsletter • 0 implied HN points • 18 Jan 26
🕹 Technology Open Source
  1. AI coding agents are replacing human attention to docs and code, breaking attention-based monetization and already harming projects and jobs.
  2. Existing open-source business models (support, open-core, hosting, donations, dual licensing) are vulnerable to agent automation, so contributors need to shift from donation/attention models to utility-based monetization where execution is metered.
  3. The Glass Box Protocol proposes treating code as a capability: keep specs and tests open but publish verified executable blobs (e.g., Wasm) plus a manifest that meters and prices execution so humans can learn for free while agents pay for utility.
