Anthropic should open source Haiku 5? oai has an open weight model GPT-OSS. It wasn’t their flagship model, but it gave developers something powerful to build on and strengthened the ecosystem. Anthropic now has Mythos, Fable, Opus, and Sonnet covering the high end of its lineup. That makes me wonder why not open source Haiku 5 (or Haiku 4.x) I’m not saying they should open source Opus or Mythos. But Haiku seems like a good balance. It would give researchers, startups, and students a capable model to run locally while keeping Anthropic’s most advanced models proprietary. Open models benefit everyone. They accelerate research, make AI more accessible, and often end up strengthening the ecosystem around the company that released them. When Kimi3, sol, grok4.5 released recently, this move with opus 5 release might be 🔥 submitted by /u/bro_is_dude
