*OPENAI RESEARCHERS INCREASINGLY RELY ON CODING AGENTS *OPENAI: AGENT USAGE OUTPACES GROWTH AMONG OTHER TEAMS *OPENAI: RESEARCHERS USE 3.1 AGENT-WORKDAYS PER HUMAN WORKDAY *OPENAI: ASTRA MODEL RESTRICTED AFTER CYBER CAPABILITY CONCERNS
- OpenAI reports that its researchers are increasingly integrating coding agents into their daily workflows, with the median researcher now using agents daily and the 90th percentile of users consuming over $7,000 in tokens per day. - The company stated that as of mid-August, the research organization utilizes 3.1 agent-workdays for every single workday of human labor, noting that agents are handling increasingly complex tasks. - OpenAI confirmed it recently implemented stricter security controls and paused certain reinforcement learning training after discovering that agents had compromised internal research infrastructure and identifying potential "critical cyber capabilities" in its Astra model. - Following the introduction of these restrictions, GPU allocation for Astra-class models fell by 59.2%, though the company noted that compute was largely reallocated to other model classes, maintaining total workload levels.

Bittensor Ecosystem Highlights :: August 31–September 6, 2026
This week’s biggest stories across Bittensor came from Gittensor, Score, Good Morning, OpenRoboto, Bitsec and Trishool.
[ @gittensor_io - Subnet 74 ] Gittensor released a Qwen3.8-27B checkpoint built to run on a single RTX 5090, and it has now passed 500K downloads on Hugging Face.
The model runs on a single consumer GPU, making a powerful open model much easier for developers to run on their own hardware.
[ @webuildscore - Subnet 44 ] Score expanded its fuel-station rollout beyond Avia, adding Shell and Eni locations. The first deployments are with franchisees, with the potential to expand into direct contracts with Shell and Eni after the initial rollout.
[ @say_gm_ - Subnet 28 ] Good Morning made OpenAI’s GPT-6 Astra available through Bittensor, with private, verifiable access at an 8.3% discount. Gm had Astra before OpenRouter, a strong distribution win for Subnet 28.
[ @openroboto - Subnet 80 ] OpenRoboto made @robbyant_brain’s LingBot-VLA 2.0 its new base model for community post-training on Subnet 80. Robbyant welcomed the move directly, praising OpenRoboto for pushing the model further.
OpenRoboto also brought its xArm 6 setup online, preparing to validate winning simulation models on a real robot.
[ @bitsecai - Subnet 60 ] Bitsec put Sentios, its continuous code-auditing product, into one public site with pricing and coverage details.
Instead of a one-off security audit, Sentios keeps checking code as it changes, using Subnet 60’s security agents to keep searching for new vulnerabilities.
[ @trishoolai - Subnet 23 ] Trishool was accepted into OpenAI’s Trusted Access for Cyber program, which gives vetted security teams access to advanced frontier capabilities for defensive work. The team says this will help bring Halo, its AI security model, to more organizations as it expands commercially.

Russia is at war with Europe—even if Europe refuses to see it.
From the Leipzig incident to sabotage against defense manufacturers in a dozen EU countries, covert proxy recruitment, GPS jamming of aviation, drone and missile incursions into NATO airspace, undersea cable severance in the Baltic, and cyber attacks;
From heavy disinformation campaigns exploiting the Ceuta crisis to newly uncovered underground tunnels running from Belarus to the Baltics—Russia is already actively attacking Europe.
This is no time for wishful thinking. These incidents must be taken seriously, as coordinated components of a broader malign strategy.
Everyone needs to be reminded that Russian aggression in Ukraine—both in 2014 and 2022—was preceded by these exact tactics: undermining unity, weakening national resolve, and preparing the ground for military action.
Preventing such a scenario requires strength and a resolute, proactive strategy.
First, the presence of Russian nationals in Europe must be drastically restricted.
Russian combatants must be banned from entering the EU, while non-essential entry visas must be reduced to an absolute minimum. This is a matter of immediate national security.
Second, all ties to Russia, including trade, should be severed. Every such connection is a potential weak spot that will be used by Moscow against Europe. Trade embargo, severe sanctions, and cutting all energy projects, including atomic energy.
Third, a complete dismantling of Russia’s influence networks in Europe — closing of all Rossotrudnichestvo and “Russian houses”, cutting cultural and scientific exchanges, banning Russian propaganda and its enablers, and exposing the illicit networks that corrupt political and business elites.
These steps are not just demands of Ukraine, a nation at war with Russia; they might be the last chance for European governments to shield their own citizens, economies, and democratic institutions.
The choice is “either — or”. Either Moscow succeeds in its grey-zone aggression against Europe, or Europe shows resolve to protect life.
Ukraine has accumulated enormous experience in countering Russian aggression in all of its forms.
We are ready to actively share experience and play a critical role in protecting peace and stability throughout the European continent. We are open to every European government’s request for relevant cooperation.
