| Lemons float. Limes sink. Same family, very different work ethic. | It comes down to density; lemons are buoyant enough to bob, while limes are more likely to drop straight to the bottom. | Even citrus has favourites, and limes are clearly the moodier sibling. | What’s in store: | OpenAI gave the API a mouth and a notes app. AI is getting better at judging chemical reactions.

| | | OPENAI | | | OpenAI has added new voice features to its API to help developers build apps that can talk, transcribe, and translate conversations in real time. | The main update is GPT-Realtime-2, a voice model built for more natural conversations. | OpenAI says it uses GPT-5-class reasoning, which should help it handle more complex requests during live chats. | The company also launched GPT-Realtime-Translate, which can understand more than 70 languages and translate into 13. | It is designed to keep up with conversations as they happen. | Another new tool, GPT-Realtime-Whisper, offers live speech-to-text transcription for calls, meetings, events, media work, and accessibility tools. | The main points: | GPT-Realtime-2 is built for more natural and complex voice conversations. GPT-Realtime-Translate supports 70+ input languages and 13 output languages. GPT-Realtime-Whisper provides live transcription as people speak.
| Meetings may suffer | OpenAI says the goal is to move voice AI beyond simple back-and-forth replies, making it able to listen, reason, translate, transcribe, and act during a conversation. | The tools could be useful for customer service, education, media, events, and creator platforms. | OpenAI also says it has added safeguards to help prevent misuse, including spam, fraud, and harmful content. | All three models are available through OpenAI’s Realtime API. Translate and Whisper are billed by the minute, while GPT-Realtime-2 is billed by token use. | ChatGPT is about to make my vacations more interesting. - MV | Would you trust an AI voice agent to handle a customer service issue? | | Vote for live results + see results and opinions from yesterday at the bottom of the email. |

| | The pettiest use of automation so far | Someone on social media claims there’s a script that automatically calls spam callers back and traps them in endless voice loops, basically wasting their time the same way they waste everyone else’s. The idea is simple: take the most annoying people on earth and hand them their own personalised circle of hell. | There’s no verified developer or public code behind it yet, so for now it sits somewhere between revenge fantasy and possible tool. But that has not stopped people from loving the concept, because the thought of robocallers getting stuck in their own scammy little maze is deeply satisfying. |

| | | AI SCIENCE | | | Designing new molecules is one of the hardest parts of chemistry. | Whether researchers are making a new drug or a new material, they need to plan every reaction carefully. | That means working out which steps are most likely to succeed and which ones could waste time. | A key challenge is retrosynthesis, where chemists start with the final molecule and work backwards to find the best way to make it. | Computers can search through huge numbers of possible routes, but they still struggle with the kind of judgement experienced chemists bring. | Researchers at EPFL have developed a new AI framework called Synthegy to help with this. | Instead of generating molecules on its own, it helps existing chemistry software judge possible routes. | The main bits: | Synthegy lets chemists guide AI tools using plain language. It helps rank possible reaction routes and mechanisms. The goal is to support chemists, not replace their expertise.
| Plain English enters the lab | Chemists can give Synthegy simple written instructions, such as asking it to form a ring early or avoid unnecessary protection steps. | The system then reviews possible reaction paths, scores how well they match the request, and explains its reasoning. | Synthegy can also help analyse reaction mechanisms, which show how reactions happen step by step. | It checks possible pathways and helps point researchers towards the ones that make the most chemical sense. | In testing, 36 chemists reviewed its results across 368 valid evaluations. Their views matched Synthegy’s results 71.2% of the time on average. | Retrosynthesis sounds like a villain origin story, and honestly, fair - MG |
