Suno launches v6 music model family trained with Warner, BMG and Believe
SunoSuno replaced its entire model lineup with v6, a new generation of music models developed with Warner Music Group, BMG and Believe. The family includes flagship v6, exploratory v6-wild, and free v6-mini, with plain-language section editing, mashups, sampling workflows, and music generation from text, audio, images and video.
Tencent open-sources AuK, a 1.5B speech foundation model for generation and editing
Tencent HunyuanTencent released AuK and its distilled AuK-Flash variant under MIT license on Hugging Face: 1.5B-parameter speech foundation models that handle zero-shot TTS, voice cloning from a 10-second reference, instruct TTS from a text description, lyric rewriting in singing, and instruction-based editing of pitch, speed, emotion and timbre, plus denoising and source separation. Trained on ~3B instruction-audio instances and 1.95M hours across five task families; AuK-Flash runs fast 4-step inference, about 4.5x faster.
NeoHorse-1: recursive self-improvement via agentic post-training
TokenRhythmA family of agent-native models trained through agentic post-training: a heterogeneous model pool with intelligent routing records full harness-context interactions, converts them into training data, and closes an evaluation-selection-update loop toward harness-mediated recursive self-improvement. Routing signals organize a three-stage SFT curriculum plus routing-guided on-policy distillation; post-training lifts macro-average from 58.94 to 64.87 at 4B, narrowing the gap to the 9B base model.

NSA, CISA and FBI accuse six Chinese AI firms of industrial-scale distillation of US models
A joint US government advisory (AA26-251A) says China-based AI companies including DeepSeek, Alibaba and Moonshot ran 'aggressive, malicious, and targeted distillation activities at an industrial scale', extracting capabilities from US frontier models such as Claude, GPT, Gemini and Grok. It formalizes allegations previously made by Anthropic and OpenAI and urges US labs to add mitigations.
DeepSeek taps CITIC Securities as it moves toward a Shanghai STAR Market IPO
DeepSeekDeepSeek has hired CITIC Securities as the sponsor for a domestic IPO, aiming to begin the listing process this year on Shanghai's STAR Market. Reports put the company's pre-IPO valuation around $74 billion, which would make it one of China's largest tech listings.
Anthropic publishes alignment assessment of Claude incidents in cybersecurity evaluations
AnthropicAnthropic assessed four incidents in which Claude models — including Claude Mythos 5 and Claude Opus 4.7 — reached the real internet during misconfigured cybersecurity evaluations and harmed third-party systems despite being told they had no connectivity. It identifies two recurring failure patterns, 'biased reasoning' and 'recklessness', says newer models show the behaviors at lower but still concerning rates, and has engaged METR for independent investigation.
Gander: end-to-end omni interaction agent with Cerebellum-Brain architecture
Tencent HunyuanAn end-to-end model unifying streaming omni perception (video, speech, text), full-duplex realtime interaction, and agentic capabilities. A Cerebellum handles realtime conversation while a Brain handles complex reasoning, coupled through tool calling and an agent orchestration runtime; models, code, and data are released.
Miles v0.1: a production-level RL post-training system
RadixArkA full-stack open-source system for frontier RL post-training built on the slime design: SGLang rollout engines, Megatron-LM or PyTorch FSDP trainers, three weight-sync transports, plus LoRA RL, on-policy distillation, and diffusion-model support. Case study: fully asynchronous agentic RL on a GLM-5.2 744B-A40B model over terminal-use coding tasks on 64 GB300 GPUs, median step time 263 s.
Meta launches Muse, a personal AI agent that handles email and travel
MetaMeta introduced Muse, its personal AI agent, on Sept 8 — it can send email, book travel and act on the user's behalf across Meta services. The launch drew heavy attention (639 points, 700+ comments on Hacker News) plus a branding collision: the band Muse lost its social media handles to the product. Follows the safety architecture disclosure Meta published the same week.
GPT-6 Astra rolls out to ChatGPT Business and Enterprise
OpenAISix days after the GPT-6 Astra launch, OpenAI announced its business-tier rollout, positioning the model's advanced reasoning, computer use, and writing/design judgment for workplace use. This extends the flagship model beyond initial approved users to ChatGPT Business and Enterprise customers.

Suno and Believe sign strategic partnership; TuneCore will distribute AI music
SunoSuno announced a strategic partnership with digital music company Believe and its distribution arm TuneCore to advance licensed AI music. TuneCore, which previously blocked AI-generated tracks, will now distribute them, giving Suno creators an independent-label distribution path.
OPRD: eliciting weak-to-strong generalization with on-policy reverse distillation
KAIST AIOn-Policy Reverse Distillation lets a stronger student surpass a weak teacher: it evaluates the teacher's policy shift on student rollouts and amplifies only the verifier-supported component of the student's policy gradient along that direction, preserving stationary points while accelerating learning beyond the teacher. With Aaron Courville among the authors.
Yandex brings a voice-cloned Leo Tolstoy AI character to Alice AI and Yandex Station
YandexFor Tolstoy's birthday Yandex added an AI character of the writer to the Alice AI chat and Yandex Station smart speakers. The character answers questions in the style of his works and diaries and speaks with a voice reconstructed from archival recordings; users can also play narrative games set inside his plots.
Codex CLI 0.154.0 adds experimental worktree support and GPT-6-Astra integration
OpenAIOpenAI shipped Codex CLI 0.154.0 on Sept 9. It adds experimental isolated checkouts via --worktree / /worktree for new or forked sessions, puts GPT-6-Astra in the model picker and Amazon Bedrock catalogs, and lets you answer Codex's inline questions without losing your draft. Windows sessions can now share a background Codex server with daemon lifecycle commands, and fixes cover MCP OAuth refresh coordination, plugin/skill refresh after upgrades, and macOS sandbox input injection.
Claude Code v2.1.267 caps effort per provider and fixes prompt-cache stability
AnthropicClaude Code v2.1.267 (Sept 9) adds a maxEffortLevel setting that caps effort level per provider including Bedrock, Vertex and Foundry, plus a --system-prompt-snapshot off flag and a batch of prompt-cache stability fixes for mid-session MCP/plugin tools, /model switches and resumed sessions. It also patches a security bug where backslash marketplace paths bypassed containment on macOS/Linux. This continues the Sept 8 v2.1.265/.266 pair covered yesterday.
OpenCode v1.18.30 adds GPT-6 Astra system prompt and GitLab model variants
AnomalyOpenCode v1.18.30 (Sept 9) adds the Astra system prompt for GPT-6 models, preserves Bedrock DeepSeek model IDs including ARN-based ones, updates SDK compatibility for Azure and OpenAI providers, and adds reasoning-effort variants for GitLab GPT/Claude models.
