Last month, we demonstrated high-rate alchemy: turning mercury into real, stable gold, beating CERN’s record by a factor of 10. Last week, we enriched isotopes in the world’s most powerful plasma centrifuge, beating the Soviet record that stood for 40 years. Now, we’re building a fusion reactor in San Francisco to achieve record power density.
Part of the conversation: Startups claim records in fusion, alchemy and speech AI
@MarathonFusion (25.8K likes, 8.9M views) says it turned mercury into stable gold at a rate beating CERN's record by a factor of 10, enriched isotopes in the world's most powerful plasma centrifuge to beat a Soviet record, and is now building a fusion reactor in San Francisco. @RagavanThurair (17.1K likes, 4.5M views) says his team made Dessa, a full-duplex speech-to-speech model trained entirely on speech that runs on consumer GPUs, calling it a GPT3 moment for speech.

We made the first AI model you can have a realistic conversation with that was trained entirely on speech! Dessa is a full-duplex speech-to-speech model that you can run on consumer GPUs. This is a GPT3 moment for speech. https://t.co/XVD8sSyJn8
