MiniMax Says Its H3 Open-Weight Video Model Is Near the Frontier

# About ThursdAI The weekly show that keeps AI builders ahead of the curve. ThursdAI started as a weekly X Space and grew into one of the most trusted sources for AI news in the builder community. Every Thursday at 8:30 AM PT, Alex Volkov goes live with a rotating panel of researchers, engineers, and founders to break down what actually matters. No hype. No fluff. Just the signal — model releases, research breakthroughs, open source updates, and the real implications for people building with AI every day. The show is also available as an edited podcast on Spotify and Apple Podcasts, and as a detailed weekly newsletter on Substack with links, analysis, and community discussion. [...] From Weights & Biases — presented for the community of AI builders who need to stay sharp without drowning in noise. ## Podcast Platforms Listen on major platforms, or subscribe via RSS. ## Your Host Alex Volkov is an AI Evangelist at Weights & Biases, CEO of Targum.video, and an independent AI cons

Aviv with some friends. More on that soon.Wrapping upThat’s the episode: one riff on using AI like you mean it, one conversation with the person shaping how developers experience OpenAI, and one podcast where Wolfram and I had to answer the hard questions for a change. Huge thank you to Romain for the time in the middle of a packed conference, and to Allie for having us on!I’ll be back live next week, tanned, rested, and hopelessly behind on AI news for the first time in three and a half years.

Finally we chatted with Max from Pangram about the next version of AI writing detection (their biggest yet) and finished with Zuckerbergs (also on X! what’s going on with everyone joining X) op-ed on the vision of personal superintelligence for everyone. Let’s dive into this (as always, all the links and sources at the end, please don’t forget to sub to our podcast on your favorite podcast app!) Open Weights AI Kimi K3 the king of open weights - 2.8T chonker MoE near frontier model (X, HF, Blog, Tech report) This has got to be the biggest news of this week, and maybe the open weights AI news since GLM 5.2.

Here? All systems go. Every conversation is about agents, token factories, software factories, the machine that builds the machine. Everybody is chasing RSI — recursive self-improvement. Every talk on stage is somebody pushing the frontier. Every networking event is actually a networking event. I signed up for something like seven side events and skipped them all to write this. ## Fable is back (and Sonnet 5 is… meh) 🏢 [...] Dominic Kundel (OpenAI). Smoothest transition we’ve ever done: local AI → OpenAI, via the guy behind GPT‑OSS. Dom broke down GPT‑5.6 — three models: Sol (frontier), Terra (~5.5-level intelligence at half the cost), Luna (small & fast) — plus the new Ultra mode with a Max reasoning level and heavier sub-agent use. The headline for me: 5.6 Sol is coming to Cerebras at absurd speed, and it’s the same weights as the API model — not a distill, not “a Spark situation.” Also: the Codex app is five months old (!), 100% of OpenAI engineers use it, and yes — in July 2026,
