GPT 5.6 : Checkpoints (Kindle Alpha, Kepler Alpha extreme high) appearing on Arena sites. OpenAI patching its weakest spot, front-end/UI generation, to power Codex into a “super app” and claw back market share from Anthropic.

Mythos : A model slug appeared in dev mode this weekend confirms a full Claude Mythos class model. Suggests Anthropic is timing a drop to generate hype and pull users back from Codex.

Grok 5 (or grok v9-medium?): Confirmed by elon/xai stuff, training done on a massive 1.5t param model, public release eyed for mid-june. it’s been delayed, but prediction markets already had like 33% chance by end of May…

3.5 Pro : Sundar officially announced that it is coming at Google IO last month

Kimi K3 : Leaks point to it being a massive jump (like 3-4T params territory) to go toe-to-toe with the top frontier models. Polymarket’s sitting at ~59% chance of dropping by end of june, but it’s been hovering there and no hard confirmation.

If all of these drop - is this month set to be the greatest in AI model release history? 🤞 submitted by /u/Chasmchas
