AI avatar news, October 8, 2026: what is worth acting on

The avatar news that changes a purchase this week: Synthesia launched Sessions and new plan credits on October 1, 2026; Tavus announced Griffin-Lite the same day but only for select testers; HeyGen's September release put an open-source live-avatar demo stack on GitHub on September 10. Microsoft Teams and Zoom pages describe meeting avatars. Only the Synthesia items can be bought this week.

Sume ships no live avatar. It ships a rendered, script-driven Avatar 1.0 video, so the table also says what each item means for that route.

The dated list

Each row below comes from the vendor's own page, read on 2026-10-08.

What to act on

If you train sales or support staff, Synthesia's Roleplay Training at $29 per learner a month is the one new product with a price. If you build a conversational product, Griffin-Lite is a request-access form, not an API. The Tavus page says Griffin-Lite will not be available to customers at this time and expects a release after safety concerns are addressed.

HeyGen's repositories are worth reading if you plan a live avatar on top of an LLM; they need a LiveAvatar key, so they are not free to run.

What it means for Sume users

Nothing in the week changes Sume's catalog. Avatar 1.0 stays at $0.184, $0.245 and $0.55 a second for Standard, Plus and Max, 4 to 60 seconds a job, 720p. If you were waiting on a live product, you can ship the recorded part now: intro clips, step-by-step answers, scenario prompts. Add live later where the conversation is the point; the six questions help decide where.
