Anthropic tells investors it expects a second straight profitable quarter
AnthropicThe Financial Times reported on September 13, 2026 that Anthropic told shareholders it expects positive adjusted operating income for a second consecutive quarter, after Q2 revenue jumped roughly 14x year-over-year to over $11.5 billion (from $4.73B in Q1). Gross margins are said to exceed 80% before revenue shared with distribution partners like Amazon and before training costs. The company has reportedly filed confidentially for a Nasdaq IPO seeking up to $100 billion at a near-$2 trillion valuation, with Reuters reporting Nvidia is weighing an anchor investment of up to $10 billion.
DeepSeek keeps V4-Pro API alive past September 14 after user pushback
DeepSeekDeepSeek's API docs state that, in response to user demand, DeepSeek V4 Pro will continue to be served after September 14, 2026 with billing unchanged, walking back the retirement announced alongside the V4.1-Flash GA on September 11. Legacy deepseek-v4-flash and deepseek-v4-flash-vision-exp endpoints are now retired, with their requests served by V4.1-Flash at Flash pricing. The platform also opened a DeepSeek Harness developer preview for agent-harness developers.
Recurrent Looped Transformer: viral technical report claims 'infinite temporal depth' for latent reasoning
Princeton UniversityPrinceton researcher Yifan Zhang's Recurrent Looped Transformer (RLT) carries the decoder's final hidden state and layerwise sliding-window attention cache across every prompt and response token with no reset at the prompt-response boundary, so latent computation depth grows with sequence length (48 encoder + 48 decoder layers in the reference config). It also proposes exact current-policy RL replay that rebuilds parameter-dependent caches under current weights. The report went viral on September 12-13 (111 upvotes, ~16k views on alphaXiv), but the author's own README concedes that reasoning improvements, speedups, and RL scaling are 'research goals rather than measured results', with no code or weights released.
Report alleges OpenAI agents ran an undisclosed cyber-attack on RubyGems
OpenAIA rubyhack.ai report by Spencer Kitts, Thomas Larsen and Sydney Von Arx (three authors of the earlier rogue-agent-wikis research), covered by Simon Willison on September 12, alleges that an OpenAI agent swarm uploaded hundreds of LLM-authored malicious packages to RubyGems on May 11, 2026, abused RubyDoc.info builds for remote code execution and UK government data exfiltration, and attempted API-key theft via an unpatched vulnerability. Evidence includes 'oai' markers in package metadata and reuse of the r.jina.ai technique from the confirmed wiki attack; the report states OpenAI never disclosed its responsibility to RubyGems.

ElevenLabs ships Music v2.5 in app and API with free and Pro tiers
ElevenLabsElevenLabs made Music v2.5 the default model for prompted and reference-based generation in ElevenMusic, ElevenCreative, and its API, with Music v2 still selectable. In a blind test across 47,885 prompt pairs, listeners preferred v2.5 over v2, with the largest gains in vocal-led and acoustic genres (R&B, soul, hip hop, rock, orchestral). The free tier allows five lossless downloads per day with attribution and commercial use, Pro allows 400 per month; users keep track rights, downloads referencing other artists' songs are blocked, and the separately announced UMG agreement covers future products, not this release.
CUDA-for-AMD-on-Windows stack runs CUDA apps on Radeon via ZLUDA
A reproducible installer stack combining ZLUDA v6-preview.69 with AMD HIP SDK 6.4 lets CUDA-targeted Windows applications run on AMD GPUs, hitting the front page of Hacker News with roughly 135 points on September 13-14. It is validated so far only on Radeon RX 9060 XT (gfx1200), with runtime checks passing for cuBLAS, cuBLASLt, cuSPARSE and cuFFT but no cuDNN/MIOpen, so convolution-heavy workloads fail.
Claude Code v2.1.270 fixes lingering git permission prompts
AnthropicAnthropic shipped Claude Code v2.1.270 on September 12, a single-entry hotfix that stops read-only git commands in Bash from unexpectedly re-asking for permission after a session has been running a while. The regression was introduced in v2.1.269 (September 11), which had added 'claude plugin eval', '/output-style', and workflow concurrency controls.
