Description
Claude Fable 5.5 is an anticipated but currently unannounced model in Anthropic's Claude family, and Anthropic has not confirmed that a model with this name will be released. As of September 30, 2026, Claude Fable 5.1 remains the latest officially documented Fable model. Fable represents Anthropic's highest-end model tier for demanding reasoning and long-horizon agentic work, while the newer Opus 5.5 and Sonnet 5.5 occupy lower-cost positions in the Claude lineup. Anthropic's current documentation gives Fable 5.1 a 1-million-token context window and maximum output length of 128,000 tokens. It supports text and image inputs with text output and uses adaptive thinking that remains active throughout model operation. Fable 5.1 defaults to high reasoning effort and is listed as having a June 2026 reliable knowledge cutoff and training-data cutoff. API pricing is $10 per million input tokens and $50 per million output tokens, while prompt-cache reads cost $0.25 per million tokens and Batch API processing receives a 50% input and output discount. Anthropic's official documentation currently provides model identifiers for Fable 5.1 across the Claude API, Amazon Bedrock, Google Cloud, Microsoft Foundry, and Claude Platform on AWS. No equivalent model identifier, specifications, benchmark results, pricing, availability information, or release schedule has been published for Claude Fable 5.5.
Description
Claude Tag is a collaborative AI teammate from Anthropic that brings Claude into Slack so teams can delegate work directly from shared channels. Instead of using Claude only in a private chat or one-off coding session, users can tag @Claude in a Slack conversation and assign tasks while the team keeps working. Claude can use the tools, data, codebases, and channel context that administrators choose to connect, helping it complete work with more relevant background knowledge. Within a channel, Claude behaves like a multiplayer assistant because everyone can see what it is doing and continue from the same thread. It can plan tasks, break work into stages, respond with finished outputs, and work asynchronously over longer periods. Claude Tag can also learn from permitted Slack channels and connected data sources while keeping memories scoped to the channels and access rules defined by administrators. If ambient behavior is enabled, Claude can proactively flag relevant information, follow up on unresolved threads, and keep teams updated. Administrators can manage sensitive data access, set monthly spend limits, review activity logs, and create separate Claude identities for different teams or workflows. Claude Tag is built for organizations that want to make AI delegation part of everyday team collaboration.
