AI Daily｜DeepSeek Releases V4.1-Flash; OpenAI Launches Agents API & GPT-Live-1; Cognition Unveils SWE-2

Model Releases & Updates

DeepSeek-V4.1-Flash — DeepSeek

• TL;DR: DeepSeek released DeepSeek-V4.1-Flash, a 552B Mixture-of-Experts model featuring a novel Causal Encoder-Decoder architecture, native visual understanding, and a dramatic reduction in KV cache overhead.
• Key Highlights:
  • Employs an asymmetric input-output design (8B active prefill, 16B active decoding) optimized specifically for long-context agentic and coding workloads.
  • Slashes global KV cache requirements to 890 bytes per token (roughly 1/4 of V4 Flash), enabling efficient 1M-token context windows at bottom-barrel pricing.
  • Outperforms several previous flagship models on terminal execution, coding, and cybersecurity benchmarks while undercutting standard API rates.
• Specs: 552B MoE (8B/16B active) / Causal Encoder-Decoder / MIT License / Open Weights

SWE-2 — Cognition

• Cognition: Cognition launched SWE-2, its newest coding model scaled via multi-trillion-parameter reinforcement learning to match frontier performance at significantly reduced inference costs.
• Key Highlights:
  • Achieves a 50.0% score on FrontierCode 1.1 Main, performing on par with leading proprietary frontier models like Claude Fable 5.1 at up to 70% lower operational expense.
  • Built on an extensive multi-trillion-parameter RL recipe that pushes the Pareto curve on complex software engineering tasks.
  • Seamlessly integrated into Cognition’s cloud development sandboxes and desktop execution environments.
• Specs: Multi-Trillion-Parameter RL / Proprietary / Code Generation & Agentic Workflows

AuK — Tencent Hunyuan

• TL;DR: Tencent Hunyuan open-sourced AuK, a unified foundational speech generation and editing model designed for zero-shot text-to-speech, audio manipulation, and high-throughput inference.
• Key Highlights:
  • Combines natural-language instructions with reference audio to handle zero-shot TTS, emotional intonation shifting, voice style transfer, and de-accenting.
  • Features an optimized AuK-Flash variant supporting 4-step inference, delivering a 4.5x speedup under matched hardware conditions.
  • Includes robust audio utilities such as background music separation, denoising, and Whisper-based conversion.
• Specs: Open-Source Speech Foundation Model / AuK-Flash 4-Step Inference / Open Weights
• Links: Hugging Face Papers |

Research Papers

ToolGrad: Efficient Tool-Use Dataset Generation with Textual Gradients — Google Research

• Motivation: Creating high-quality tool-calling datasets for complex agent training is historically bottlenecked by expensive human annotation and rigid programmatic generation scripts.
• Key Innovation: Google introduced ToolGrad (published at ACL 2026), a data generation framework where an LLM first synthesizes tool-calling chains and then applies “textual gradients” to reversely annotate user queries.
• Results: Significantly reduces dataset generation overhead while boosting tool-selection accuracy and chain-of-thought alignment in complex agent evaluations.
• Paper: Google Research Blog
