Hume AI

Hume AI builds empathic voice AI, with its Empathic Voice Interface and Octave text-to-speech, plus emotion recognition models. Hume's pricing page, read directly, shows no pricing: it is a product marketing page about infrastructure to improve voice AI with Talk to Hume and Evaluate Your System buttons and no plans, prices or free tier. An aggregator says Hume pulled its public pricing page and that the pricing URL redirects to the homepage as of October 15, 2026, with billing documents describing one subscription and $20 in free credits, while earlier 2026 reviews list a seven-tier structure from Free to $500 a month, such as Free with 10,000 characters and 5 EVI minutes, Creator at $14 and Business at $500, verified on July 4, 2026 by one source. Another review lists Creator at $10 and Scale at $150 and calls the $14 and $500 figures outdated. Treat it as contact sales.

The corporate news matters. Google DeepMind signed a licensing agreement with Hume AI on January 22, 2026, reported by Wired, under which DeepMind hires CEO Alan Cowen and about seven top engineers, with financial terms not public. One commentary says Hume raised $74 million and will keep providing its technology to AI labs after the deal, but I found no primary source or reporting on its post-deal product roadmap. A June 2026 change reportedly added cheaper EVI 4 mini and Octave 2 models, a single-source claim. If you plan to build on Hume, ask about continuity, support and pricing in writing.
