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.

MicroStrategy Could Drive Bitcoin to $10M If It Accumulates 7.5% Supply, Saylor Says

MicroStrategy aims for 7.5% of Bitcoin supply, implying $10M per BTC; as of Apr 19 it held 815,061 BTC (~3.88%) for $61.56B, needing ~3.62% more to target saturation in Saylor’s long‑term accumulation plan. Abstract: MicroStrategy seeks to accumulate roughly 7.5% of Bitcoin supply, a threshold Saylor suggests could push BTC to about $10 million and slow purchases thereafter. By April 19 it owned 815,061 BTC (≈3.88% of supply) for $61.56B and would require about 3.62 percentage points more to reach the target, indicating a approaching saturation of its long-run accumulation strategy.
