Fable Without Fable: Sakana Fugu Ultra's Big Bet
Sakana's most interesting move is selling learned orchestration as a frontier-model substitute, with Fable-class pressure and very different production risks.
Evidence-first analysis of agentic systems, model evaluation, and the economics of AI software. We read the system card, find the primary source, and tell you what actually changed — and what didn't.
The gap between demo and production is the harness you build around the model, not the model you license.

Model EvaluationA practitioner framework for scoring jailbreak severity, choosing benchmarks, and assuming reasoning-model attackers in your red team.
AI FrontiersArticle 50 takes effect in August. Here's the layered provenance stack that actually satisfies it.
Model EvaluationTokens-per-second-per-dollar on identical GPUs decides more deployments than peak throughput, and tail latency plus cold start decide the rest.
Model EvaluationText benchmarks have saturated, so differentiation moved to vision, audio, video, and real-time duplex tasks where evaluation is still immature and gameable.
Search & GEOMeta's billion-user Muse Spark rollout makes public Facebook posts the citation layer for AI search, opening a social-graph GEO surface no one has optimized for yet.
AI ToolsAI is no longer just answering in chat or suggesting in your editor; it is composing the interface itself, and the protocols to do it portably just shipped.
AI EconomicsGPU rental prices have collapsed 64-85% below hyperscalers, but the debt and utilization math underneath is brutal.
Models & ReleasesA single Commerce Department letter switched off Anthropic's Fable 5 worldwide; Praxis wants to make sure the next frontier model can't be turned off the same way.
AI FrontiersWhen the AlphaFold architect leaves DeepMind for Anthropic, the message is clear: foundation models are commoditizing, and the moat moved upstream.
Model EvaluationBenchmark scores don't predict production vision AI failures. Here's the evaluation stack teams actually ship.
AI FrontiersCourts are now pricing fabricated AI citations at $500 each, and the verification workflow that stops them is cheaper than a single sanction.
Security & SafetyThe DOJ's xAI intervention turns 'national security' into a legal lever to skip Clean Air Act permits, and founders building AI infrastructure should track every move.
