OpenAI releases GPT-6.1 Terra computer-use model as Google DeepMind previews Genie 4 world model with audio
OpenAI released GPT-6.1 Terra, a cheaper mid-tier computer-use model that meets its Critical cybersecurity threshold. Google DeepMind previewed Genie 4, a real-time world model with audio whose control loop already includes a Gemini planning agent.

Reach: not measured yet
GPT-6.1 Terra reads the screen, acts across apps and writes. It is available in ChatGPT, Codex and the API at $1 per million input tokens and $5 per million output tokens, half its predecessor's price. On Terminal-Bench 4.0, OpenAI's own figures show Terra solving 50.3% of tasks against 21.5% for GPT-5.6 Terra, and no third-party testing has been reported yet. [2] [4] [5]
Terra meets OpenAI's Critical cybersecurity level, which means a model can find or build zero-day exploits against hardened systems without human help. It keeps safeguards first built for GPT-6 Astra, so deployments where it controls a computer call for sandboxing and least-privilege access. [2]
Genie 4 generates real-time video with native audio, including character dialogue. Users can steer it with typed prompts mid-session, and scenes stay consistent for about two minutes, up from roughly one minute in Genie 3. Access is limited to trusted testers for now, with wider rollout to Ultra subscribers and Gemini API partners planned. [3] [6]
Genie 4 already combines the two approaches the agents-versus-world-models debate treats as rivals. Genie renders the pixels, Gemini Omni keeps appearance and behaviour realistic, and Gemini 3.8 Flash acts as an agent that breaks goals into steps, checks incoming frames and revises its plan. Google is also pairing Genie 4 with Gemini Robotics. [1] [3] [6] [8]
Terra is available now at mid-tier prices, while Genie 4 remains a limited preview with no benchmarks. This suggests computer-use agents are ready to pilot under tight access controls. The value of world models for robotics remains speculative.
Sources are gathered and checked, and I'm writing the dossier now.
Executive brief
The cheaper model in this pairing is also the riskier one on paper. OpenAI's GPT-6.1 Terra is a mid-tier computer-use model priced 50% below its predecessor. It also meets OpenAI's own "Critical" cybersecurity threshold, the top risk level in OpenAI's internal risk framework (Help Net Security). The next day, Google DeepMind announced Genie 4, a real-time world model that generates audio along with the scene (DeepMind). The Reddit post asks whether AI that acts (agents) or AI that simulates (world models) will matter more. Neither launch comes with independent evaluation yet. Every Terra benchmark comes from OpenAI, and Genie 4 was released with no benchmarks at all.
What changed and event timeline
Genie 3 sets the baseline
Genie 3 generated interactive worlds at 720p and 24 fps and could remember a scene for about one minute. It followed Genie 1 (2D, March 2024) and Genie 2 (3D, December 2024) ()).
Project Genie opens to consumers
AI Ultra subscribers got access to Genie 3 through Google Labs, with sessions capped at 60 seconds because of compute costs ()).
First Critical-level OpenAI model
GPT-6 Astra was the first OpenAI model designated Critical for cybersecurity under the Preparedness Framework ().
GPT-6.1 Terra launches
It rolled out in ChatGPT Work, Codex and the API (,). Help Net Security gives the date as October 27.
Genie 4 research preview
The release adds native audio, steering by typed prompts mid-session and more photorealistic worlds. Access is limited to trusted testers for now ().
Capabilities and access
- GPT-6.1 Terra (API name
gpt-6.1-terra): reads the screen, acts across apps and writes. It is available to Plus, Pro, Enterprise and Edu users. EU in-region routing through Azure costs $1.20 / $6 (OpenRouter). - Genie 4: real-time video plus audio, including character dialogue, with scenes held consistent for up to about two minutes (TechCrunch). Wikipedia lists up to 30 fps (Wikipedia)).

API pricing is $1 per million input tokens and $5 per million output tokens (Help Net Security). EU in-region routing through Azure costs $1.20 / $6 (OpenRouter). Free users stay on GPT-5.6 Luna (Decrypt). - Genie 4: real-time video plus audio, including character dialogue, with scenes held consistent for up to about two minutes (TechCrunch). Wikipedia lists up to 30 fps (Wikipedia)). Access goes to Ultra subscribers and early Gemini API / AI Studio partners "in the coming weeks."
Technical analysis for researchers and developers
- Genie 4 is a hybrid system. In other words, the world model already has an agent built into its control loop.
- Reproducibility is low for both. Terra's error-rate test is an internal benchmark (Decrypt).
- Terra lets developers set a reasoning-effort level, which changes cost, speed and accuracy (OpenRouter).

- Genie 4 is a hybrid system. Genie handles pixel-level simulation. Gemini Omni keeps appearance and behaviour realistic, and Gemini 3.8 Flash acts as a guiding agent: it breaks a goal into steps, checks incoming frames and rewrites its plan (DeepMind, DataCamp). In other words, the world model already has an agent built into its control loop.
- Reproducibility is low for both. Genie 4 has no paper, no benchmark table and no comparison with other world models (DataCamp). Terra's error-rate test is an internal benchmark (Decrypt).

All Terra figures below are OpenAI's own, and no third-party testing has been reported (Decrypt).
- Terminal-Bench 4.0: 50.3% of tasks solved, versus 21.5% for GPT-5.6 Terra, both at maximum effort (Decrypt).
- Error rate on OpenAI's internal test: fell from 53.6% to 16.7% at low effort, and to 4.3% at maximum effort (9to5Mac).
- Agents' Last Exam: 15 points above GPT-5.6 Terra at about one-third the cost. OpenAI also says Terra is more than three times faster than GPT-6 Astra (Help Net Security).
- Genie 4: Google's claims of improved realism and physics rest only on its own demos (DataCamp).
Context and prior work
- Genie's progression: 2D at 1 fps in 2024, then 3D clips of 10–20 seconds, then 720p with one-minute memory.
- Competitors and deals: Runway released GWM Worlds 2. AMD acquired World Labs, Decart is in talks with Amazon, and Rivian bought Third Dimension (TechCrunch).
- Terra's lineage: it is the mid-tier sibling of GPT-6 Astra and GPT-6.1 Sol (Help Net Security).

Limitations, safety and contested findings
- Terra's cyber rating: Critical means a model can find or build zero-day exploits against hardened systems without human help.
- Genie 4's admitted weaknesses: objects and details drift over long sessions, complex physics is imperfect, and text and spatial accuracy are weak.
- Sim-to-real is unproven: Google showed a humanoid robot demo, but nothing measures how well behaviour learned in Genie 4 carries over to real hardware (DataCamp).

- Sim-to-real is unproven: Google showed a humanoid robot demo, but nothing measures how well behaviour learned in Genie 4 carries over to real hardware (DataCamp).
- Release date conflict: sources disagree on Terra's launch date (October 26 vs. 27).
Business and practitioner implications
- Agents are ready to pilot; world models are not. Genie 4 is still a preview with no benchmarks.
- Run it on your own workflows before relying on OpenAI's internal numbers.
- The Reddit post's option C (both together) is already happening. Pairing them doesn't settle whether simulation transfers to real-world tasks.
