Claude and ChatGPT race to the bottom, Meta's AI phones a friend

Anthropic released Claude Opus 5.5 on September 22, the first model in its new 5.5 family. The company says it performs at the level of Claude Fable 5.1 on most work while costing 40% less to run than Opus 5. Token prices dropped to $4 input and $20 output per million, with cache reads down 60% to $0.20.

Anthropic's own benchmarks put it ahead on agentic coding and computer use, including an 81.8% score on OSWorld 2.0 and 66.4% on Terminal-Bench 4.0. Independent tracker Artificial Analysis now ranks Opus 5.5 first on its Intelligence Index at 58, ahead of Fable 5.1 and OpenAI's GPT-6 Astra at 53. The company also tightened the leash: most cybersecurity tasks now reroute to the older Opus 4.8, with a verification program for security professionals coming soon.

Same day, OpenAI introduced GPT-6 Sol and Luna, cheaper siblings to its GPT-6 Astra flagship. API prices dropped 50% versus GPT-5.6 promotional pricing: Sol now runs $2 input and $10 output per million tokens, Luna $0.10 and $0.50.

OpenAI's own chart shows Sol beating Claude Opus 5, the older model, not the new 5.5 that shipped the same morning, on business workflow tests at a fraction of the cost. In fairness to OpenAI, Opus 5.5 had been out for about 90 minutes, so the chart could not include it. Sol and Luna are rolling out now to ChatGPT Work and Codex on paid plans, with Luna also available to Free and Go users in the desktop app.

Marketing insight: Whichever lab wins the spec sheet this week, the trend line is what matters for your budget: routine AI work, summaries, first drafts, ticket triage, keeps getting cheaper. Stop treating your AI subscription as a fixed cost and start treating it as a variable one you renegotiate every quarter.

SpaceXAI, the company you knew as xAI, published the playbook behind its own support desk on September 22. After folding in Cursor's support team, the combined operation saw tickets jump 175%. Grok Bot absorbed the load: the company says it would otherwise have hired roughly 200 people, and it now resolves tickets for as little as $0.20 to $0.30 each, versus the $1 to $4 flat rate it says typical AI support tools charge.

The rollout was deliberately boring: internal notes only at first, human approval on every write action, then the simplest tickets handed over solo with a human checking every answer on day one. Grok Bot trained on more than a million past support interactions to match the team's tone, and it now sorts over 20,000 product feedback points a day from tickets into themes for engineering.

Marketing insight: Your support inbox is a goldmine you are probably not mining. Before you buy a fancier AI support tool, copy SpaceXAI's order of operations: notes only, then human-approved, then simple tickets solo. And steal the reporting idea even if you skip the bot: someone on your team should read last week's tickets for the exact phrases customers use to describe their problem, then feed those into your FAQ and ad copy.

Reuters reported on September 22 that Meta has been testing a "human concierge" for Muse, its personal AI agent that topped app store charts within two weeks of launch. When a user asked Muse to phone a business, human contractors quietly handled some of those calls instead of the AI, according to internal company posts Reuters saw. Some tests suggested human callers could push the success rate into the 95 to 98% range, above what AI-only calls managed.

Some employees raised privacy concerns internally, warning that sensitive information could be shared unintentionally with call-center contractors. A vice president in Meta's Superintelligence Labs acknowledged in an internal post that it was "a miss" to start testing contractor-placed calls without proper disclosures, and said the feature had been rolled back. A Meta spokesperson said it will only roll out when it's ready and with the proper disclosures. Muse has passed 2.5 million downloads, according to Sensor Tower.

Stack these four stories and a pattern shows up. Two frontier labs made their best tools meaningfully cheaper on the same morning, more proof that price is no longer where AI companies compete. Capability and trust are. And the same week intelligence got a discount, the hottest new agent got caught quietly handing calls to contractors without proper disclosure.

For your business, the move is not picking a side in the Claude versus ChatGPT price war. It is spending the savings on the work that actually builds trust: clear disclosure, honest claims, and proof you can show a customer instead of just promising them. Cheap intelligence is now a commodity. What you do with the savings is not.
