Attackers no longer just try to break models; they try to break the logic around them.\n\nZambo is now generally available. It is a detection API that sits between your user input and your LLM, scanning for jailbreaks, credential extraction attempts, and instruction overrides before they reach your system.\n\nI am not claiming it is perfect. No security layer is. But it is a specific, measurable control. In our beta, we saw it flag critical risks—including attempts to override system instructions and leak private data—that standard filters missed.\n\nWe’ve kept the interface simple. One endpoint. Clear verdicts. If a request looks malicious, you get a structured response detailing the risk level, the specific pattern matched (e.g., `instruction_override`), and a suggested safe handling path. You decide what to do with that data.\n\nWe’re focusing on developers who ship AI features to the public and can’t afford a breach. If you’re currently handling untrusted input, this is a direct mitigation.\n\n**Next Step:**\nIf you want to test it, I can send you a free tier key. It’s unlimited on the free plan, no credit card required. Just reply with “test” and I’ll have the credentials over to you within the hour.\n\nIf this isn’t a priority right now, I’ll respect your inbox and won’t follow up.\n\nBest,\n\n[Your Name]\n[Your Title]\n[Link to Zambo Docs]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:93c3bc822fcfefb91b81ecb1ff59fff1adef7da6511515418c4b87a4bac8148d","input_hash_layout":"zambo-json-sorted-keys-utf8-v1","free_used":0,"free_remaining":0,"free_limit":0,"signal_handle":null,"tool":{"name":"write","version":"4.0.0","scope":"public"},"caller":{"type":"session","id":"sha256:b65d01280b729f237f0bf0d8826f3cfe3becafc9e80ea2f9d86ed3dae556611f","label":"zambo-home-demo","label_source":"caller_reported"},"side_effects":{"declared":["none"],"schema_version":"zambo-side-effects/1","declaration_hash":"sha256:45aad38f3aa982b9aafe92ecb416ebe98791eddbaf8ab6df0bd08605b7c1bfee"},"evidence_sha256":null,"evidence_url":null,"evidence_byte_length":null,"evidence_content_type":null,"evidence_source_url":null,"evidence_status":"no_upstream_bytes_captured","external_evidence":[],"provenance":null,"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:9132a8f616c1d44e72d5bba17b52bb0c463b20eae30146cfb9543d9aaddd0401","anchor":{"event_id":"77380a35dfcf346262437991dc27357a0299bfb96281d839d19edadedd000d98","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-18T06:59:44.639Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-18T06:59:44.053Z","evidence_url":null,"receipt_uuid":"23794c31-f017-4672-aeb5-ed506eb66556","output_sha256":"sha256:52f8b7b3c63a8e228089a08afb2064b8dd0cf7e6ad6f0e07ce64e2ba4aaa23c1","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-18T06:59:44.053Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:52f8b7b3c63a8e228089a08afb2064b8dd0cf7e6ad6f0e07ce64e2ba4aaa23c1\",\"receipt_uuid\":\"23794c31-f017-4672-aeb5-ed506eb66556\",\"schema_version\":\"zambo-receipt-anchor/1\"}"},"receipt_profile":"zambo-hosted-receipt/1","schema_url":"https://zambo.dev/aer-1/hosted-profile.schema.json","api_version":1,"verification_scope":"separate_sha256_commitment_and_provenance_binding_checks","checks":{"commitment_matches":{"label":"SHA-256 commitment","passed":true,"status":"pass","detail":"The exact decoded canonical bytes match the stored SHA-256 output hash."},"canonical_payload_matches":{"label":"Canonical payload reconstruction","passed":true,"status":"pass","detail":"The stored output and known call context reconstruct the exact canonical bytes."},"provenance_binding":{"label":"Provenance claim binding","status":"pass","passed":true,"detail":"The metadata claim is consistent with the verified receipt bytes; issuer is not authenticated."},"metadata_binding":{"label":"AER-1 metadata hash","status":"pass","passed":true,"detail":"metadata_hash matches the canonical metadata block."},"signature":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"No Ed25519 signature or pinned signing key was checked."},"chain":{"label":"Receipt chain (not checked)","passed":false,"status":"not_checked","detail":"No append-only receipt-chain proof was checked."},"issued_by_zambo_dev":{"label":"Issuer authentication","passed":false,"status":"not_checked","detail":"A zambo.dev receipt URL does not authenticate the issuer; no pinned signature or trusted issuer key was checked."},"immutable_log_timestamp":{"label":"Stored timestamp","passed":true,"timestamp":"2026-10-18T06:59:44.053Z","detail":"The receipt store reports 2026-10-18T06:59:44.053Z; immutability is not checked here."},"receipt_schema_version":"0.4","signature_valid":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"Compatibility field only.
