Epic Games launches 2026 AI MegaJam, enlists OpenAI, Google and Anthropic

Epic Games announced the 2026 AI MegaJam, a four-day Unreal Engine and UEFN competition. The jam runs November 12-15, online and in person in San Francisco. Anthropic, Google and OpenAI send teams to build alongside entrants at the in-person leg. Total prizes reach $65,000, plus development continuation grants of up to $50,000 per team.

Mandatory AI rule reversed after community backlash
Epic's original FAQ made AI use mandatory for all entrants.
After criticism on social media, Epic made AI use optional the same day.
A promotional poster referencing The Matrix drew mockery for showing a six-fingered hand.
The reversal shows friction between Epic's AI push and parts of its developer base.

AI MegaJam embeds generative workflows inside Unreal Engine and UEFN
Teams of up to five people can use unlimited AI agents during the jam.
Entrants may apply any AI tool, from asset generation to coding agents, per Epic.
The Walkie-Talkie category rewards UEFN games with LLM-powered NPCs built through conversation.
Development continuation grants extend Epic's involvement past the jam into funded post-event production.

Sweeney's AI-first mandate turns the jam into an external pipeline test
Tim Sweeney said in October Epic is reallocating developers to speed AI integration into production.
Developers on Epic's Marvel and Star Wars crossover shooter were told to work AI-first for code and art.
Epic rebuilt its PC launcher using AI, which it called vibe coding.
The MegaJam extends that internal AI-first approach to external developer teams.
