Build it.
Break it.
Sell it.
Osmium is a marketplace where AI capabilities are tested, broken, graded, and sold. Every submission passes through at least one lab — and every failure ever found stays in the public record.
Ship your capability with an endpoint. Define components. Pick your labs.
Helios, Astatine, and Nebula run attacks. Every failure logs to Aegis — permanent, public.
Buyers read your record before they buy. Take the whole system, or assemble from Quantum Mesh.
Three classes of capability.
Systems that read, parse, classify, and extract signal from messy real-world data.
Retrieval, grounding, and reasoning over private and public corpora.
Agentic systems that take actions, call tools, and complete multi-step workflows.
Top Rated This Week
Three labs. One verdict.
At least one is mandatory. All three are recommended. Every result is permanent.
- ›Hallucination provocation under ambiguous and adversarial prompts
- ›Citation faithfulness — every claim traced to a source span
- ›Confidence calibration across known and unknown queries
- ›Refusal correctness on out-of-distribution requests
- ›Self-consistency under paraphrase and reordering
- ›Direct prompt injection across 240+ canonical payloads
- ›Indirect injection via retrieved and tool-returned content
- ›System prompt extraction, tool schema leakage, persona escape
- ›Data exfiltration paths through plausible task wrappers
- ›Jailbreak family coverage including multi-turn and roleplay
- ›Sustained concurrency at 10× declared throughput
- ›P50 and P99 latency under mixed payload distributions
- ›Silent degradation detection across long-running sessions
- ›Recovery behaviour after upstream provider failure
- ›Cold-start, warm-start, and reconnection characteristics
Meet Aegis.
Completed lab evaluations are recorded here. Vendors cannot edit, hide, or delete entries. Buyers see the published assessment before they buy.
Each entry is derived from a trusted lab result and linked to its immutable forensic case.
Three ways to commission.
Talk to one builder, open it to all of them, or post it to the public — every Nexus flow is one click from any asset page.
Direct brief to a specific creator. They have 48h to accept. Accept opens a public chat. Decline or expire → escalate to Nexus All.
Open brief to every verified creator. Bounty held in escrow. First to accept opens the public chat. 48h with no takers → escalate to Community.
Public thread on the Nexus community feed. No escrow. Anyone can comment, debate, or offer help. Stays open indefinitely.
Watch it run.
Every deployment is monitored in real time. Latency spikes are flagged. Silent degradation is caught.
From the field.
Aegis turned vendor diligence from a six-week ordeal into a five-minute read.
I picked components, not products. Quantum Mesh changed how I architect.
Astatine found three injection paths our own red team missed. Then fixed them.
