The analysis compares orbital and ground-based systems across launch cost, power generation, cooling, radiation exposure, and atmospheric reentry, as well as compute-network performance. A key distinction is the shift from terrestrial Clos networks to space-based mesh networks using laser inter-satellite links. Using bisection bandwidth, bisection intensity, and roofline-style models, we show that while LEO-based inference may be feasib","authors_text":"Kees van Berkel","cross_cats":["cs.AI"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.DC","submitted_at":"2026-07-15T09:42:59Z","title":"The Cost and Network Limits of Space-Based AI Compute"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.14172","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:8886aca0ba42bcbe9289f27017edd40d1ebf244ca9e993ab7cd41afbafb1ceac","target":"record","created_at":"2026-07-17T00:20:55Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"60bfbb6686b74ba27312717efbc0fcc572c404b26a79f1ce8d023a3fa27884fd","cross_cats_sorted":["cs.AI"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.DC","submitted_at":"2026-07-15T09:42:59Z","title_canon_sha256":"1bdb7ba42dd85b1c1477b42759360b4d00ae9bc2acc5ea976ea34fcc3757cfb2"},"schema_version":"1.0","source":{"id":"2607.14172","kind":"arxiv","version":1}},"canonical_sha256":"4f2f96d8352f8756cb4bccc943996641eea8bb7d82a90c5f91b37a36e27d28b0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4f2f96d8352f8756cb4bccc943996641eea8bb7d82a90c5f91b37a36e27d28b0","first_computed_at":"2026-07-17T00:20:55.105925Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-17T00:20:55.105925Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"dgNi356KWZ5ppAiySiIxaAdnL8G7KOEBaJ2NEFUyz0LxH0m6FlIolNsCsSNL51URm0/mWseZ1GFuCOwV2HghDw==","signature_status":"signed_v1","signed_at":"2026-07-17T00:20:55.106825Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.14172","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8886aca0ba42bcbe9289f27017edd40d1ebf244ca9e993ab7cd41afbafb1ceac","sha256:12f586ebcea5e60a9f67adc989a9d324b87b44166141b0772fbe63916b4f80ec"],"state_sha256":"a93ccd2148128399efd3a57eed4e3585505e8af8d381854b4eda401fca82b515"}
