How Braintrust turns customer requests into code with Codex

For decades, software engineering has relied on something surprisingly fragile: veteran developers passing down institutional knowledge from person to person. As AI transforms how code gets written and maintained, that culture of inherited memory may be starting to break apart.

PLUS: Use Codex to build a functional game in one prompt

Learn how Endava uses Codex to build an agentic organization, accelerating software delivery and reducing requirements analysis from weeks to hours.

Back-to-back price cuts from China's top AI labs have made their models a fraction of the cost of GPT-5.5 and Claude Opus.

NVIDIA researchers have introduced Polar, a rollout framework that trains language agents using reinforcement learning without modifying their agent harnesses. Polar places a model API proxy between the harness and the inference server, capturing token-level interactions and reconstructing trainer-ready trajectories. Using GRPO on a Qwen3.5-4B base model, Polar improves SWE-Bench Verified pass@1 by 22.6 points under the Codex harness, 4.8 points under Claude Code, and 6.2 points under Pi. The framework is registered as a NeMo Gym environment and released under the ProRL Agent Server repository. The post NVIDIA Releases Polar, a Token-Faithful Rollout Framework for GRPO Training Across Codex, Claude Code, and Qwen Code appeared first on MarkTechPost.

Claw-Anything simulates a real digital existence and asks AI assistants to handle it. GPT-5.5, the best model available, scored 34.5%.

Cisco and OpenAI are redefining enterprise engineering with Codex, helping Cisco scale AI-native development, accelerate AI Defense work, and automate defect remediation.

See how OpenAI, Thrive, and Crete built a self-improving tax agent with Codex, automating filings, improving accuracy, and accelerating workflows.
