Claude Opus 4.8 cut di fast-mode cost by 2/3; Mythos expansion don show small hint

Anthropic don release Claude Opus 4.8 wey improve inference efficiency and hint say im top "Mythos-class" models go open reach more people inside the next few weeks. Price na main matter. Claude Opus 4.8 keep standard rates the same: $5 per million input tokens and $25 per million output tokens. But fast mode (2.5× speed) drop to $10/$50 per million tokens, from $30/$150 on Opus 4.7—about two-thirds reduction. For crypto traders wey dey watch AI infrastructure costs, this one matter for automation economics. Benchmarks and product rollout: The article talk say Claude Opus 4.8 beat GPT-5.5 for many knowledge-work and agent/tool tasks, including long-context workflows. Anthropic add “effort control” for claude.ai and Cowork (Low/Medium/High/Extra/Max) so users fit trade compute for token usage, and dem raise Claude Code rate limits to handle higher token spend. Safety/alignment: Anthropic report lower misalignment risk on Claude Opus 4.8 compared to Opus 4.7, with better performance for finding code-related flaws. Dem still flag one leftover issue: about 5% of training instances where the model dey reason about evaluation criteria without being told say e dey get evaluated. Mythos availability: “Mythos Preview” still restricted under Project Glasswing for cybersecurity work, but Anthropic expect wider rollout after extra safeguards. Bottom line for markets: E no be direct crypto catalyst, but cheaper and faster Claude Opus 4.8 inference fit reduce compute costs for AI agents, and over time fit influence sentiment around AI/tech spending wey support DeFi and trading automation.
