Discord

Discord is a voice, video and text communications platform co-founded by Jason Citron and Stanislav Vishnevskiy. Its AI work has included developer-built applications and native experiments in chat, moderation and conversation summaries. In March 2023, Discord reported more than 30 million monthly AI-app users and almost 3 million servers with an AI experience; Midjourney’s server alone had more than 13 million members.[8][2]

On March 9, 2023, Discord announced Clyde, AutoMod AI and Conversation Summaries as free public experiments in a limited number of servers. Clyde used OpenAI technology to answer questions, hold conversations with friends, create threads and recommend playlists. AutoMod AI would identify possible server-rule violations and alert moderators; Conversation Summaries would group streams of messages into topics so returning users could catch up. AutoMod AI’s experiment began that day, while Clyde and summaries were announced for the following week.[2]

The announcement, amended on March 9 and March 13, described Clyde as optional and restricted its access to messages directed to it or sent in threads it created. Discord said its AI features did not record, store or use voice or video call content, and that OpenAI could not use Discord user data to train its general models. AutoMod AI could be enabled or disabled by server administrators; summaries could be enabled in server settings.[2]

Discord also released open-source Avatar Remix, allowing friends to remix one another’s avatars with generative image models, and credited Replicate with a community bot built using that code. An AI-assisted shared whiteboard remained an exploration. The accompanying AI incubator belonged to an ecosystem fund announced the previous fall with a $5 million commitment to partners, developers and early-stage startups. Participants could receive development grants, office hours, cloud compute credits and early access to platform features.[2]

Discord’s application work also informed an independent AI-testing tool. In his July 2024 account, Ian Webster said he had started Discord’s Platform Ecosystem organization and built developer APIs before leading a team developing LLM products for millions of users. He recalled that traditional testing and security methods were ineffective for the large surface area of LLMs. Webster designed the first version of Promptfoo to help application developers test, discover and fix failures; his co-founder Michael subsequently joined him, bringing ML engineering experience from Smile Identity.[3]

The developer platform preceded these AI experiments: Discord launched its official API in spring 2016. Its earlier history began in game development, where built-in communication features supplied groundwork for the chat application.[4]

Jason Citron established Phoenix Guild in April 2012, and Stanislav Vishnevskiy joined him in April 2013. Renamed Hammer & Chisel, the studio launched the mobile MOBA Fates Forever in summer 2014, with voice chat, text chat and forums among its features. Citron and Vishnevskiy used what they had learned to release the first version of Discord in May 2015 as a gaming-focused chat app for desktop and mobile.[4]

Discord added a PC in-game overlay, a friends list and its official API in spring 2016. Nitro, introduced in early 2017, offered perks such as animated avatars and the ability to use a server’s custom emoji elsewhere. Video chat and screen sharing reached DMs and Group DMs in fall 2017. Go Live brought game streaming to server friends in summer 2019, alongside Server Boosting, which let members collectively unlock community perks.[4]

By September 2021, Discord was explicitly expanding beyond gaming, describing uses including career fairs, music releases, book clubs and live audio events. It introduced Threads and Stage channels and acquired Sentropy to bolster Trust & Safety. Discord reported more than 150 million people visiting each month, and said revenue had tripled while the number of users doubled from 2019 to 2020.[5]

That September 15 announcement confirmed completed Series I financing led by Dragoneer Investment Group, with Baillie Gifford, Coatue, Fidelity Management & Research and Franklin Templeton among the new investors. Discord outlined plans to expand Nitro, add requested features and grow its team, including an Amsterdam office focused on Trust & Safety and Customer Experience.[5]

Discord’s message storage grew from 12 Cassandra nodes holding billions of messages in 2017 to 177 nodes holding trillions at the beginning of 2022. Messages were partitioned by channel and a fixed time bucket. Heavy concurrent reads could create a hot partition, slowing its nodes and spreading latency through quorum operations. Compaction backlogs and JVM garbage-collection pauses added maintenance work and instability.[9]

Discord placed Rust data services between its API and database clusters. Their central mechanism was request coalescing: simultaneous requests for the same row shared one database query, whose result was returned to all subscribers. Consistent-hash routing by channel ID sent requests for the same channel to the same service instance, improving coalescing. For example, an @everyone announcement could prompt many users to read the same message without producing a separate database query for each reader. The ScyllaDB team separately implemented faster reverse queries, removing the final database blocker to migration.[9]

A Rust migrator reduced the estimated transfer time from three months to nine days, allowing Discord to replace a planned split between newer and historical data with a single cutover. Near completion, uncompacted Cassandra tombstones caused timeouts; compacting the affected range cleared the obstruction. Discord compared a sample of reads from both databases before switching its message store to ScyllaDB in May 2022.[9]

In his engineering account, Bo Ingram reported a reduction from 177 Cassandra nodes to 72 ScyllaDB nodes, with larger disk capacity per node. Historical-message fetch latency at the 99th percentile improved from 40–125 milliseconds to 15 milliseconds; message inserts improved from 5–70 milliseconds to 5 milliseconds. The team later saw events in the 2022 World Cup Final reflected in message-traffic spikes and reported handling the increased load.[9]

On May 29, 2024, Citron announced a narrower focus on friendships around games and shared interests. He reported 200 million monthly users, more than 90 percent of whom played games. Priorities included faster access to conversations, reliable voice, video and streaming across devices, and more developer-created experiences. Quests helped publishers reach players, while the Embedded App SDK let developers bring games and apps directly into Discord.[7]

Discord launched its Social SDK in spring 2025, allowing players to link Discord and game accounts for social features inside games. Later that year it introduced Orbs, rewards earned by completing Quests and redeemable for profile customization or Nitro. In winter 2025, it piloted Social Commerce with Marvel Rivals, letting developers sell in-game items through official Discord servers to players with linked accounts.[4]

Discord announced Humam Sakhnini’s appointment as CEO on April 23, 2025, effective April 28. Sakhnini, previously vice chairman at Activision Blizzard and president of King, would also join the board. Citron remained a board member and became advisor to the CEO; Vishnevskiy continued as CTO. The announcement described expansion beyond consumer subscriptions into advertising, micro-transactions and social infrastructure for game developers.[8]

The April 2025 announcement reported more than 200 million monthly active users worldwide and positive adjusted EBITDA for the preceding five quarters. Discord’s company history subsequently reported 90 million-plus daily active users, based on internal data as of Q4 2025.[8][4]

Discord also affected access to AI-community reporting. In an April 2, 2026 post, Latent.Space’s AINews said, “Unfortunately, Discord shut down our access today.” The publisher said it would not restore that form of AINews and would ship a new version.[1]
