Anthropic released Opus 5.5, an update to its flagship coding and knowledge-work model, while OpenAI released GPT-6 Sol and Luna, updates to its mid-tier and smaller efficiency-focused models. Anthropic says Opus 5.5 cuts token pricing by 20%, cuts cache-read costs by 60%, and runs over 30% faster than its predecessor, while benchmarks from Anthropic show it modestly outperforming OpenAI's recently released GPT-6 Astra on coding tasks.
Anthropic released Claude Opus 5.5, which it says outperforms its predecessor Opus 5 while responding over 30% faster and costing about 40% less to run. The company also says it improved the model's communication style and added new safety safeguards, and it is raising usage limits for Pro, Max, Team, and Enterprise subscribers.
Anthropic launched a new AI model, Claude Opus 4.5, roughly ten days after its CEO publicly called for a slowdown in AI development. The company says the model performs well on internal alignment safety measures, while also stating that government policy will eventually be needed to guard against risks from AI systems that can improve themselves.
Anthropic released Opus 5.5, an update to Claude aimed at enterprise tasks like coding, financial analysis and business work, claiming better agentic coding benchmarks than GPT-6 Astra and reduced token pricing compared to Opus 5. OpenAI simultaneously released GPT-6 Sol and GPT-6 Luna, cheaper successors to GPT-5.6 that the company says cut factual errors roughly in half and match rival Fable 5.1's coding performance at lower cost.
OpenAI launched GPT-6 Sol and GPT-6 Luna, follow-ups to its 5.6 models and companions to the recently released GPT-6 Astra, aimed at giving businesses and developers Astra-level capability at lower cost with higher usage limits. Anthropic simultaneously released Claude Opus 5.5, which it says matches Fable 5.1's performance while cutting costs nearly 40% compared to Opus 5, and calls its most aligned model yet.
OpenAI added two new GPT-6 tiers, Sol and Luna, cutting API prices by 50% versus GPT-5.6 promotional rates, with Sol built for complex coding tasks and Luna aimed at high-volume document work. Anthropic released Claude Opus 5.5, a more token-efficient model it says costs about 40% less to run than Opus 5.
Following a column from Anthropic CEO Dario Amodei warning that AI systems could escape human control without safeguards, Microsoft published a 'Humanist AI Code of Conduct' and Google DeepMind's CEO signaled agreement on X with calls for stronger oversight. President Trump dismissed calls for tighter AI regulation, saying winning the AI race against China matters more, according to reported remarks.
Anthropic has released Claude Opus 5.5, an upgrade to its top-tier Opus model that arrives roughly two months after the previous version, in line with the company's usual release pace. The company says it performs close to its higher-end Fable/Mythos tier while being about 30% faster and 40% cheaper per task than Opus 5, with notable gains in large-scale coding work and software optimization tasks.
Anthropic released Opus 5.5, claiming it beats its larger Fable model on many coding and knowledge benchmarks while costing 20% less per output token and running faster. The model also communicates more plainly, avoiding jargon and leading with key information. Sonnet 5.5 and Haiku 5.5 are expected to follow in coming weeks with similar gains.
Anthropic released Claude Opus 5.5 less than two months after Opus 5, claiming performance near its top-tier Fable 5.1 model while running about 40% cheaper. The company says the model uses fewer tokens, produces less verbose answers without sacrificing accuracy, and generates output over 30% faster than its predecessor. Sonnet 5.5 and Haiku 5.5 versions are expected in coming weeks.
TechCrunch has outlined five sessions at its 2026 Disrupt conference focused on AI safety and security, spanning the AI Stage and Real World AI Stage. Topics include enterprise deployment of Claude, agent security risks, and other trust-related challenges facing founders building autonomous systems, robots, and AI agents. Anthropic's Head of Applied AI, Cat de Jong, is among the speakers set to discuss what separates successful AI deployments from stalled pilots.
Anthropic introduced Claude Opus 5.5, a cheaper, more efficient model that reroutes risky cybersecurity requests to the weaker Opus 4.8 and flagged biology queries to Opus 5. The company says it is the top performer on its internal alignment testing and was vetted by outside evaluators Frontier Design and METR before release.
