Re:How We Made a Text-to-Speech Model Respond in Sub-50 ms on Saturday August 22, 2026 @03:15AM (#49397387)
Sub-50ms on text-to-speech running on an LLM is commendable.

We recently shipped text-to-speech and speech-to-text support inside Finsight (Maxint). We tapped into the platform’s native speech capabilities, which were integrated with the user’s preferred LLM inference endpoint (including local on-device models). This approach enabled us to eliminate latency and preserve user’s privacy, delivering human-like conversational experience.

Since your approach involves running the model directly, did you run into memory bandwidth contention or audio buffer underruns during bursty generation, when both the LLM and TTS models are executing concurrently?

How does your VM handle local state and performance, when the user attempts to fetch, join and render data from multiple endpoints?

We use Dart and Go (front/backend) to allow users to render widgets/mini-apps on Maxint (Finsight). And hence, the speed (virtually instant) and overall quality of the output mostly depends on the LLM/inference endpoint that they choose.

In general, most users are happy with the existing features, however more advanced users have a playground to ship enhancements on-the-fly.

The Pixel 9 Pro was designed for Google Fi, but the iPhone 16 Pro outperforms it

When I signed up for Google Fi, Pixel was advertised as the "native" device for the network. It was designed to handle the MVNO's specific switching logic and carrier configurations better than any BYOD device.However, six months into my contract, as the signal was dropping a few times a day, I got another line for testing on my iPhone. I’ve been gathering data on signal stability for Google...

Depositors lost trillions since the last few years in purchasing power due to low interest on deposits at the banks and high inflation: https://blog.maxint.com/purchasing-power-loss/

Be careful with treasuries, during times when the Government is heading towards default otherwise pick the highest yield and lowest fee option, SGOV offers the highest yield right now, here are the latest rankings, based on yield and fees: https://blog.maxint.com/treasury-bill-etf/ unless you don't want to pay any fee and do it yourself via https://www.treasurydirect.gov/

There are a lot of money market funds, make sure you read their prospectus to understand where they invest your money. VMRXX offers the highest yield right now, here are a few more: https://blog.maxint.com/best-money-market-funds/ which are also a good alternative when the Government is heading towards default.

Prioritize based on your needs and financial circumstances, starting with MMFs, treasury ETFs and lastly consider bank accounts for a small % that you need to have available on-sight. This is not financial advice.

Thanks! A long thread with good insights.
