Perplexity Discloses Web Search Agent Post-Training Method; Qwen3.5-Based Model Outperforms GPT-5.4 on Accuracy and Cost

Perplexity uses SFT followed by RL with Qwen3.5 models, leveraging a multi-hop QA dataset and rubric checks to boost search accuracy and efficiency, achieving best-in-class FRAMES performance. Abstract: Perplexity's post-training workflow for web-search agents combines supervised fine-tuning (SFT) to enforce instruction-following and language consistency with online reinforcement learning (RL) via the GRPO algorithm. The RL stage uses a proprietary multi-hop verifiable QA dataset and rubric-based conversational data to prevent SFT drift, with reward gating and within-group efficiency penalties. Evaluation shows Qwen3.5-397B-SFT-RL achieving top FRAMES performance, 57.3% accuracy with a single tool call and 73.9% with four calls at $0.02 per query, outperforming GPT-5.4 and Claude Sonnet 4.6 on these metrics. Pricing is API-based and excludes caching.

OpenAI Codex Team Fixes OpenClaw Authentication Bug, Significantly Improves Agent Behavior

OpenClaw switches from Pi to Codex harness to fix a silent authentication fallback, with two PRs addressing the bridge and fallback; post-fix, the agent shifts from shallow heartbeat polling to a full work loop, enabling progress. Abstract: OpenClaw’s Codex harness optimization addressed a critical authentication flaw that caused silent fallback to the Pi harness when using Codex with OpenAI models. Two pull requests fix the authentication bridge and prevent silent fallback, changing the runtime adapter. As a result, agent behavior evolves from shallow heartbeat polling to a full work loop that reads context, analyzes tasks, edits repositories, and verifies progress, improving continuity and visibility across heartbeats.

Anthropic weapon-grade cybersecurity model Mythos was accessed without authorization: how did they do it?

Bloomberg reported that a private forum group gained unauthorized access to Mythos through legally authorized use by a third-party contractor of Anthropic. Mythos is an enterprise-grade, defensive AI that is only available to large organizations that undergo rigorous review. The group used knowledge of the model URL to guess the system’s location to gain entry, and provided screenshot demonstrations, claiming it was still being used with no malicious intent. Anthropic is investigating and has preliminarily determined it was abuse of permissions rather than external intrusion. This case highlights the risk of entrusting highly sensitive models to third-party oversight, and underscores the need to strengthen governance resilience and trust mechanisms.
