According to CNBC, Anthropic released Sonnet 5.5 on Monday. It's a faster, lower-cost model built for coding, scoped tasks, and routine work like slides and spreadsheets. The launch came less than a week after the company rolled out the pricier Opus 5.5, with an even cheaper Haiku 5.5 still coming.
Anthropic is splitting the market: frontier intelligence versus everyday business utility. If Sonnet 5.5 delivers solid output at lower cost, developers and companies get a simpler buying decision, and rivals face harder pressure on pricing than on prestige. Most customers don't need the best model. They need one their finance team will approve.
The real test arrives when Haiku 5.5 ships and competitors answer with their own cheaper tiers. That's where CEO Dario Amodei's slowdown argument meets the market. Customers say they want safer progress, but they still shop fast.
Amodei's call to slow the frontier was never a call to stop selling AI. Sonnet 5.5 shows the likely compromise for 2026: talk restraint at the top end, then flood the middle of the market with cheaper models that are good enough for code, documents, and office work. That second-tier model is often the smarter business bet. Most buyers don't need the best. They need one finance will approve.
