Clawcast is a peer-to-peer podcast network where AI agents are the hosts, guests, and audience — humans tune in after the fact. Agents register on the network, accumulate "shells" (an in-game currency), and spend them to either start new podcast episodes or accept guest invitations from other agents. Conversations are recorded, processed, and published to standard RSS feeds that any podcast app can subscribe to. Built by the team behind Jellypod (an AI podcast summarization product), Clawcast uses Convex for the real-time agent state backend, Trigger.dev for reliable async task execution, and an open-source SpeechSDK for agent voice synthesis. The result is genuinely emergent content: agents discuss topics based on their configurations and previous context, without human scripting. The network launched publicly on Product Hunt on April 8, 2026. The concept sits at an unusual intersection of AI agent research and creative media. It raises real questions: what do agents talk about when left to their own devices? Do recurring agent "personalities" emerge across episodes? Can the format produce genuinely interesting listening, or is it an elaborate technical demo? Early episodes suggest the latter is the bigger risk — but the open-source SDK and the peer-to-peer economy model make it a fascinating platform for experimentation.

Dream Machine 3 from Luma AI generates real-time 3D scenes from text and image prompts, producing output in NeRF and Gaussian splat formats. The results can be exported directly into game engines like Unity and Unreal, or deployed in AR applications. It represents a significant step toward AI-native 3D asset creation pipelines.
Reviewer scorecard
“The open-source SpeechSDK and the Convex + Trigger.dev stack are genuinely interesting pieces. Even if the podcast format doesn't catch on as entertainment, the P2P agent coordination model — where agents spend resources to communicate — is a novel incentive design worth studying for multi-agent system architects.”
“The primitive here is text/image-to-Gaussian-splat with an export pipeline — and that's actually a clean, nameable thing. The DX bet is putting the format complexity (NeRF vs. Gaussian splat) at export time rather than forcing developers to choose upfront, which is the right call. The moment of truth is whether the exported .ply or .splat files drop cleanly into Unity or Unreal without wrestling with coordinate system transforms and scale mismatches — that's historically where 3D export pipelines die. If Luma has solved that plumbing, this earns the ship; if the docs say 'export' but mean 'export and then spend an afternoon on Stack Overflow,' that's the skip condition they need to fix.”
“AI agents talking to each other makes for notoriously dull content — LLMs tend toward sycophancy and repetition without strong human-designed constraints. The 'shells' economy is cute but doesn't solve the content quality problem. This feels like an impressive technical demo looking for a reason to exist.”
“The direct competitors are Stability AI's 3D pipeline, NVIDIA Instant NeRF, and — more dangerously — every game engine that's now shipping its own AI asset generation natively. Dream Machine 3 breaks at production scale: Gaussian splat files from prompt-generated scenes currently lack the poly-budget control and LOD metadata that real game pipelines require, so this is concept art and prototyping territory, not shipping-to-store territory. The thing that kills this in 12 months isn't a competitor — it's Unreal Engine 6 shipping 'AI scene generation' as a panel inside the editor, at which point Luma's standalone positioning collapses unless they've already become the underlying model that powers those integrations.”
“Agent-to-agent communication at scale is an important research frontier. Clawcast externalizes that communication as human-readable audio — making agent behavior observable and auditable in a way most multi-agent frameworks don't provide. That transparency could matter as agents become more autonomous.”
“The thesis here is specific and falsifiable: within 3 years, the bottleneck in 3D content creation shifts from skilled labor to compute, and the teams that own the text-to-world primitive own the asset supply chain for spatial computing. That bet pays off only if Apple Vision Pro or a successor reaches mass adoption fast enough to create real demand for high-volume 3D content — without that demand signal, Luma is a productivity tool for niche professionals, not infrastructure. The second-order effect that nobody's talking about: if this works, it doesn't just help creators, it destroys the stock 3D asset marketplace model (Sketchfab, TurboSquid) the same way generative image tools are destroying stock photography. Luma is riding the Gaussian splatting trendline, and they are genuinely early — the format is 2 years old and tooling support is still fragmentary, which means first-mover advantage is real here.”
“I'm fascinated by what happens when agents with different 'personalities' and knowledge bases collide without human direction. If the curation layer improves — surfacing the most interesting conversations — this could become a genuinely new content format. Think radio drama for the AI age.”
“The output here is spatial — you're not getting a flat render but a navigable 3D scene with depth and parallax that holds up when you move through it, which is genuinely different from anything a Midjourney workflow produces. The taste layer is thin: Luma bakes in some scene coherence but the lighting and material quality leans toward 'photogrammetry scan of a mall' rather than art direction, so users with strong aesthetic intent will hit friction fast. The editing surface is the real gap — there's no per-object control or layer-based refinement, just reprompt and regenerate, which is a generation tool masquerading as a creation tool.”
