☕️ LinkedIn trains AI job search 8x faster

• LinkedIn detailed the infrastructure behind its AI job search, stacking training optimizations to cut the time needed to distill large teacher models into a compact 0.6B-parameter ranking model by roughly 8x.
• Serving teacher models live inside the training loop on SGLang, LinkedIn's online multi-teacher distillation sped work up 3x, while an offline mode precomputes and caches teacher outputs on HDFS or NFS to avoid repeated queries.
• LiGer enabled 2x larger batches, with multi-node training, FSDP2, and H200 clusters each adding gains; FP8 was skipped for sub-8B models since casting overhead outweighed savings, and NDCG@10 rose ~24% in production for US users.

• OpenAI opened its GPT-Live-1 speech model as an API, bringing full-duplex voice that listens and talks simultaneously, already powering ChatGPT and letting developers pair it with different backend models to balance reasoning, speed, and cost.
• The model runs at $0.05 per minute and posts big benchmark gains over GPT-Realtime-2.1: 80% versus 45% on full-duplex interactivity, tool-calling accuracy up to 87% from 60%, and turn-taking latency dropping to 0.8 seconds.
• It ships with twelve new voices across various accents, dialects, and languages, and returns ASR transcripts plus response text by default; Yelp already uses it for phone reservations, reporting better call handling.

• DeepSeek today shipped V4.1-Flash, a smaller open-weight model it says beats its larger V4-Pro on quality, speed and cost while matching Claude Opus 5 and GPT-5.6 Sol on coding and terminal benchmarks.
• The mixture-of-experts model holds 552 billion parameters but activates only 8 billion while reading a prompt and 16 billion when generating, and a four-bit key-value cache cuts memory to ~890 bytes per token, a quarter of V4-Flash.
• Starting September 14 V4-Pro calls reroute to V4.1-Flash at the cheaper rate, dropping peak output pricing from $3.96 to $1.20 per million tokens, roughly 70% cheaper, with weights on Hugging Face under MIT.

• Shopify is abandoning React Native and moving its mobile apps back to separate Swift and Kotlin codebases, six years after adopting the cross-platform framework in 2020 to avoid building every feature twice.
• The reversal hinges on AI coding agents now handling enough of the implementation, translation, testing, and review work across two platforms that maintaining parallel native codebases is no longer the deciding cost it was in 2020.
• Shopify maintains three React Native libraries: react-native-skia and flash-list are being handed to new maintainers, while restyle, which has a smaller user base, will be archived at the end of 2026.

• TinyGo 0.42 now supports recoverable runtime panics, letting developers catch nil pointer dereferences, out-of-bounds slice and map accesses, and division-by-zero errors through standard defer and recover, closing a longstanding gap with mainline Go.
• Panic handling enables standard library test suites to use Goexit, SkipNow, and FailNow, though fatal conditions like out-of-memory errors stay unrecoverable, so not every runtime failure becomes catchable in constrained targets.
• The release adds Go 1.27 and LLVM 22 support plus a new UEFI target that runs Go code natively as a UEFI application before an operating system boots, widening where compiled binaries can execute.
