Anthropic ships Claude Sonnet 5.5, near Opus 5.5 at half the price
Anthropic released Claude Sonnet 5.5 on September 28, 2026 at Sonnet 5's price of $2 per million input tokens and $10 output. Anthropic says it runs more than 30% faster than Sonnet 5 and uses up to 30% fewer tokens per task. It reports 70.6% on Terminal-Bench 4.0, against 10.3% for Sonnet 5. It is the first Sonnet with the cyber safeguards used on Opus 5.5, and higher-risk security tasks fall back to Sonnet 5.
- Model release
Anthropic launches Claude Opus 5.5 at 40% below Opus 5
Anthropic released Claude Opus 5.5 on September 22, 2026, the first model in its Claude 5.5 family. Anthropic says it performs at the level of Claude Fable 5.1 on most work and generates output more than 30% faster than Opus 5. Pricing drops to $4 per million input tokens and $20 output, from $5 and $25, and cache reads fall from $0.50 to $0.20. It reports 66.4% on Terminal-Bench 4.0 and 81.8% on OSWorld 2.1. Thinking can no longer be turned off, and biology and security tasks route to Opus 4.8 unless the account is in a verification program.
- Model release
Anthropic ships Claude Fable 5.1 and Mythos 5.1
Anthropic released Claude Fable 5.1 and Claude Mythos 5.1 on September 1, 2026. Fable 5.1 holds Fable 5's $10 per million input and $50 per million output, but cache reads drop to $0.25 per million, 75% less, which Anthropic estimates cuts typical workloads by about 25% and highly agentic ones by up to roughly 45%. Anthropic reports 55.8% on Terminal-Bench 4.0 for Fable 5.1 and 60.9% for Mythos 5.1, which is the same model with different safeguards, limited to vetted organizations.
August 2026
- Launch
Vercel Chat SDK adds support for Claude Managed Agents
Vercel published a template on August 27, 2026 for running a Slack research bot on Anthropic's Claude Managed Agents through the Chat SDK. It holds one persistent Claude session per Slack thread, streams research briefs with their sources back into the thread, and needs no Slack credentials managed by the app itself.
- Update
Anthropic will watermark Claude's text output
Anthropic explained on August 14, 2026 that future Claude models will embed a watermark in generated text, to comply with the EU AI Act. It works by steering the model's choice among equally viable next words using a key plus the preceding words, leaving a pattern readable only with a decryption key. It carries no identifying information and cannot be traced to a user, organization, or conversation, and has minimal effect on code or on heavily edited text. Users cannot opt out; a detection API is planned.
- Pricing
Anthropic makes Claude Sonnet 5's lower pricing permanent
In an August 10, 2026 update to the Sonnet 5 announcement, Anthropic stated that the model's introductory pricing of $2 per million input tokens and $10 per million output tokens is now permanent. The scheduled September 1 increase to $3/$15 will not take effect.
