Caffeine Prepares V3 Upgrade After January Promptathon Draws Hundreds of Apps

Dominic Williams has signalled a major upgrade to Caffeine’s AI engine following a January “promptathon” that produced around 200 experimental applications built by users.

The promptathon, hosted at january-promptathon.xyz, invited developers and enthusiasts to test Caffeine’s V1 engine by creating lightweight apps through natural language prompts. According to Williams, the results offered a clear snapshot of what the platform can already support, even before its next technical leap.

At the end of January, the team moved from V1 and V2 development work towards a more ambitious release. Rather than continue incremental updates to V2, they opted to push directly to V3. Williams described the move as a way to maximise long term velocity, suggesting that the upcoming version represents a structural shift rather than a routine upgrade.

V3 is currently being tested by small cohorts of users. Williams hinted that the improvements will be immediately visible, with broader capabilities expanding through the rest of 2026 as refinements continue. He added that the team has no current plans for a V4, implying confidence that V3’s architecture can scale and evolve without requiring another foundational rebuild.

Part of the recent development has involved adjustments tied to training parameters and operational constraints. Williams referenced restrictions on secret keys connected to the rolling SEV SNP activation across ICP nodes, noting that the rollout is not yet fully complete. The expectation, he said, is that activation across the network will be finalised soon, which may ease some of the technical limitations seen in earlier versions.

Caffeine operates within the ecosystem of the Internet Computer, an open blockchain network designed to support decentralised applications. Its model centres on enabling users to build functional apps directly from prompts, lowering the barrier between concept and deployment. The promptathon demonstrated both the enthusiasm of its user base and the practical boundaries of the current engine.

Still, the shift straight to V3 carries risk. Skipping further iteration on V2 means the next release must justify the acceleration. While Williams’ tone suggests confidence, the broader developer community will likely reserve judgement until public access expands and performance can be tested at scale.

For now, the message from the Caffeine team is clear. A new engine is close. Testing is underway. And if V3 performs as promised, users may notice the change immediately, with further enhancements rolling out steadily through the year ahead.
