Finally, a speedup method for Minimax H3 reference to video! ComfyUI-Ref2VA-VSA adds video sparse attention to Minimax, generating 5-second clips in ~72s on an RTX 4090. It keeps reference tokens dense while pruning video attention—2.24× faster than VDN-H3 at ~13.5GB VRAM.

If you're vibe coding games or 3D assets with GPT 6 Astra, by default it'll still output pretty basic, sloppy-looking visuals...unless you use this prompt hack. You need to include a variant of the following in your prompt. Get it to spin up a separate critic agent, which takes screenshots of your generation at different angles and gives it a score from 0 to 10 (define what this means). Then, get it to keep looping until it achieves a score of >8. More details in my upcoming review video.

Highlights from GPT 6 Astra 117-page system card: First model to hit OpenAI’s Critical cyber threshold: can find unknown flaws and write exploits on hardened systems with little human guidance. Protections scaled up: isolation, encrypted checkpoints, full-trajectory/CoT monitoring, blocking alignment evals, paused non-compliant internal work. Far more jailbreak-resistant than GPT-5.6 Sol, including long chats; high-risk users can get stricter refusals (~91.5% vs ~59% on cyber jailbreaks). Better aligned: ~half as many high-severity misalignment flags as Sol on 54k internal Codex tasks. Misalignment monitoring now runs on all tool-using external Astra inference and can stop risky agent work. Harder to monitor: more CoT control, sandbagging, and some monitor evasion when told to hide; no steganographic CoT seen. Stronger against prompt injection and less likely to take destructive workplace/browser actions. Safer answers overall, including for teens (big gains on eating-disorder and age-restricted content). Better HealthBench and mental-health results; fewer user-flagged hallucinations. 100% on ExploitBench even at lowest reasoning; other cyber benches plus external review support the Critical rating. Bio/chem still treated as High, not Critical; research access is gated. Rollout is phased and identity-gated (Trusted Access, extra security, high-risk jurisdiction limits).

Another HUGE speedup method for Minimax H3. VideoDeltaNet offers up to 90x speedup with "near lossless quality". Higher quality and better instruction following than FastH3.
