Marlene Mhangami: Harnesses Matter More Than Models
Marlene Mhangami closes out her segment, saying she loves the Claude models and uses Opus through Copilot, which supports all models. She argues LLMs are generalists trained on the mean, so harnesses like Copilot matter more than raw model choice for specialized domains, and doubts current models are at AGI level. Asked what excites her, she highlights multi-model workflows and GitHub's new Critique release, where one model critiques another's output, before pointing listeners to GitHub Copilot and Copilot CLI.
Swyx: AI Engineer London, 10 Downing Street & EU/acc
Final guest Swyx joins live to discuss AI Engineer London. He explains the push to publish talk clips immediately after sessions and describes the morning visit to 10 Downing Street, praising the UK government's AI fellowship and noting the UK Chief AI Officer will give a closing keynote. He highlights the ElevenLabs booth with its Michael Caine voice, calls Luke Harries one of the world's top AI growth people, and cites Gradium's speech-to-speech work as evidence Europe can build its own AI champions. He also explains the EU/acc logo in the conference branding, saying builders must push capabilities alongside regulators.
DeepMind Sponsor & Anthropic's Mythos Marketing
Swyx says Google DeepMind was the conference's dream presenting sponsor and that he hoped to feature Demis Hassabis, who is ironically in San Francisco. He argues the AI engineer is the chief beneficiary of fierce model-lab competition, since the industry stays neutral and everyone benefits from choice. On Anthropic's Mythos, he calls the 'too dangerous to release' rollout over-marketed and speculates there is a broader narrative game tied to US politics and OpenAI's IPO beyond raw benchmarks.
