Gemini 4 Carbon is Google’s next frontier model, arriving two weeks after Gemini 4 Argon at the same introductory token prices. Google reports more than twice Argon’s success rate at generating secure code in internal tests.

Here's what changed:

• Input costs $2 per million tokens and output costs $10, with cached input discounted by 95%.
• Artificial Analysis ranks Carbon first on its updated Intelligence Index, with a score of 59.
• Google’s internal teams report that Carbon can work for days on complex, multi-step tasks.

One catch: access is rolling out first to a subset of cyber defenders. More trusted partners will follow through the Fairwind Program, while availability in Google products is planned for later. This is not yet a public developer release.

Oracle and Google plan to put Google TPUs inside Oracle’s data centers, giving OCI customers another AI compute architecture to choose from. Availability is scheduled for calendar year 2027, with deployment increasing over multiple years.

Here's what is planned:

• Oracle describes the partnership as multi-year and multi-gigawatt, with a gigawatt-scale cloud investment intended over time.
• Google’s TPU 8t targets training, with 19.2 Tbps bidirectional scale-up bandwidth and 400 Gbps scale-out networking.
• Google says its Virgo Network supports a fourfold increase in data center bandwidth.

One catch: this is a future OCI offering, not capacity you can provision today. Availability starts in 2027, and deployment will ramp over multiple years rather than arrive all at once.

NVIDIA Nemotron 3.5 Transcribe puts transcription, speaker attribution, translation, and English audio Q&A in one open-weight checkpoint. NVIDIA reports first place on Hugging Face Open ASR’s open-weight English track, at 5.33% average WER.

Here's what you can build with it:

• NVIDIA reports 32.4% cpWER on VoiceArena, ahead of NVIDIA Multitalker Parakeet with Nemotron 3 Diarization at 34.2%.
• About 4B parameters are active per token out of 30B total, and you can self-host with vLLM or SGLang-Omni.
• A medical-domain prompt reduced WER from 30.8% to 23.8% without fine-tuning by specifying English and the Latin alphabet.
• Cline processed 100 hours of audio in under three minutes with an NVFP4 version on one RTX PRO 6000 Blackwell Server Edition GPU.

One catch: this is for recorded audio, not live streaming. The NVFP4 version is still forthcoming, and its speed test used 30-second clips at high concurrency.
