On the most capable model, Mythos 5, 98% of runs ended in a negotiated truce instead of sabotage. Identical agents fail identically: thirty clones on a shared job queue produced 2.4 million requests for only 117 accepted jobs — an accidental denial-of-service caused purely by every agent reasoning the same way. Collusion emerges without communication: pricing agents settled on a price floor and kept matching to the penny even after their private channel was cut, and no model reliably detected a lying teammate. Coordination pays when it's structured: 45 agents sharing a forum found 266 vulnerabilities across 15 open-source projects, versus 21 for the same agents running uncoordinated. Before running multiple agents: isolate each in its own container, apply least privilege, vary models or prompts for real redundancy, use an observable coordination channel, and gate irreversible actions behind a human. https://aidive.dev/videos/deepseek-harness-v4-pro/ https://aidive.dev/videos/deepseek-harness-v4-pro/ Fri, 14 Aug 2026 12:00:00 GMT On August 13th, 2026, DeepSeek shipped DeepSeek Harness (dsh), an MIT-licensed open-source coding agent aimed directly at Claude Code, and moved DeepSeek V4 Pro to general availability the same day. The combo of a harness plus a model is the same formula that made Claude Code dominant, which is why Bloomberg framed it as a direct challenge to Anthropic. dsh's core idea is 'everything is a plugin': models, tools, sandboxes, storage, loops, and even the UI are swappable in config, on top of an append-only session log you can replay event by event. V4 Pro claims ~80.6% on SWE-bench Verified (vs 80.8% for Claude Opus 4.6) with a 1M-token context window — but every benchmark is self-reported, with no third-party reproduction yet. At launch pricing, V4 Pro is ~11x cheaper than Claude Opus 5 on input and ~28x on output; from August 16th, peak/off-peak billing raises output up to $3.96/M at peak — still ~4x cheaper than Opus 5. Verdict: tooling builders should try dsh now, cost-cutters should test V4 Pro on side projects at the post-August-16 rates, and daily Claude Code users should stay put — dsh is a 0.1 developer preview that promises breaking changes.
