Google Gemini 3.1 Pro and Seedance 2.0 Released [Model Behavior]

Google has released Gemini 3.1 Pro, a new core reasoning model that significantly outperforms GPT 5.2 on logical benchmarks like ARC-AGI-2 and Humanity's Last Exam. The model is now available across Google’s ecosystem, alongside the integration of the Lyria 3 music generation tool. Meanwhile, Anthropic has launched Claude Sonnet 4.6, emphasizing improved 'computer use' capabilities and security against prompt injection. In the video space, ByteDance’s Seedance 2.0 is causing friction in Hollywood as Disney and Paramount issue cease-and-desist letters over the use of copyrighted characters. We also examine Meta’s integration of the Manus AI assistant into Ads Manager and a new physics-based protein prediction tool from the National University of Singapore called D-I-TASSER, which improves accuracy by 13 percent over previous methods. Director-level AI leader Chad Thompson joins us to discuss the enterprise security risks of agentic computer use and operational resilience.

[00:00] Nina Park: I'm Nina Park. Welcome to Model Behavior.
[00:03] Nina Park: We examine how AI systems are built, deployed, and operated in real professional environments.
[00:10] Nina Park: Joining us today is Chad Thompson, a director-level AI and security leader with a systems-level perspective on automation and risk.
[00:19] Nina Park: Chad, great to have you.
[00:21] Thatcher Collins: I'm Thatcher Collins. We're starting today with Google, which released Gemini 3.1 Pro yesterday.
[00:27] Thatcher Collins: This is their updated core reasoning model, and it's posting some significant numbers.
[00:32] Thatcher Collins: It scored 44.4% on humanity's last exam.
[00:36] Thatcher Collins: And it, you know, more than doubled its own previous score on benchmarks like ARCGI2.
[00:43] Nina Park: It's a fast-moving week, Thatcher, because Anthropic also rolled out Claude Saunet 4.6.
[00:49] Nina Park: The focus there is very much on computer use, the ability for the model to navigate browser tabs and fill out forms.
[00:58] Nina Park: Anthropic noted that while it still lags behind the most skilled humans,
[01:03] Nina Park: the resistance to prompt injection attacks has seen measurable improvements.
[01:07] Chad Thompson: Exactly.
[01:08] Chad Thompson: The security aspect is where things get complicated for enterprise users.
[01:12] Chad Thompson: Chad, you look at these systems from a perspective of operational resilience.
[01:18] Chad Thompson: When we see models like Sonnet 4.6 getting better at controlling a desktop, what does that
[01:24] Chad Thompson: change for a security leader's risk assessment?
[01:27] Chad Thompson: It shifts the focus toward the integrity of the environment the AI is acting within.
[01:33] Chad Thompson: As these models gain agency to coordinate information across browser tabs,
[01:39] Chad Thompson: The risk of prompt injection isn't just about a chatbot saying something odd.
[01:46] Chad Thompson: It's about the model being manipulated into taking unauthorized actions.
[01:52] Chad Thompson: Enterprise resilience now requires strictly defined boundaries for where these agents can operate.
[01:58] Nina Park: Boundaries are certainly the theme in the creative sector this week as well.
[02:03] Nina Park: Bite Dance's Sea Dance 2.0 has gone viral for cinema-quality video generation.
[02:09] Nina Park: But it has also prompted cease-and-desist letters from Disney and Paramount.
[02:14] Nina Park: The model apparently generated clips featuring Spider-Man, which has reignited the debate over intellectual property.
[02:21] Thatcher Collins: Nina, it's interesting to see Bite Dance moving so quickly, especially with CDance 2.0, integrating sound effects and dialogue directly into the generation process.
[02:33] Thatcher Collins: While studios are pushing back, smaller production houses are looking at this as a way to produce high-budget genres like sci-fi on much smaller budgets.
[02:44] Nina Park: And we're seeing similar moves toward automation in the business suite.
[02:48] Nina Park: Meta has finalized its $2 billion acquisition of the AI assistant, Manus, and has already integrated it into Ads Manager.
[02:56] Nina Park: It's designed to handle data analysis and report generation,
[03:00] Nina Park: which MetaExpects will eventually lead to more agentic shopping tools for consumers later this year.
[03:06] Thatcher Collins: Before we wrap up, we should highlight a significant development in computational biology.
[03:13] Thatcher Collins: Researchers at the National University of Singapore have released DITASER.
[03:18] Thatcher Collins: It combines AI with physics-based simulations to predict complex protein structures.
[03:24] Thatcher Collins: They've achieved a 13% increase in accuracy over previous methods.
[03:30] Nina Park: That's notable.
[03:31] Nina Park: It's a reminder that the most impactful AI developments aren't always the most visible
[03:36] Nina Park: consumer apps.
[03:37] Nina Park: Chad, as we look at this mix of scientific breakthroughs and enterprise agents,
[03:43] Nina Park: what is the one thing leadership should be watching?
