Claude 3.5 Sonnet Brings 200K-Context Projects to Team Workspaces

Anthropic’s release of Claude 3.5 Sonnet introduces new collaborative features that transition the platform from a standalone chat interface into a shared engineering workspace. For developers and engineering teams, the rollout of Claude Projects and Artifacts changes how context is managed across organizational workflows. The updates bundle the speed of Claude 3.5 Sonnet with persistent data stores, allowing teams to ground the model in shared documentation rather than pasting context into isolated, single-turn prompts.

Collaborative Workspaces in Projects

The central feature of this rollout is Projects, a structural shift in how Claude manages knowledge. Available to Pro and Team users, Projects allows teams to organize chat sessions into dedicated folders. Each Project supports a 200,000-token context window, enabling users to upload codebases, API documentation, or architecture diagrams to ground the AI’s responses consistently across all queries within that space.

Users on the Team plan can share specific chats with their colleagues. This allows teams to curate successful prompt interactions or code generation sequences as templates for others to use when evaluating AI agents or drafting new routines. The 200K window ensures the model retains deep familiarity with the uploaded files, eliminating the need to repeatedly define system parameters for every new task.

Artifacts UI and 3.5 Sonnet Performance

Alongside Projects, Anthropic launched Artifacts in the web interface. Artifacts functions as a dedicated side-by-side panel that isolates generated content from the conversational timeline. When Claude generates code, documents, or website designs, they appear in this secondary window where users can view, edit, and iterate on the output directly.

The system runs on Claude 3.5 Sonnet, which outperforms the previous generation’s Claude 3 Opus on industry benchmarks while operating at the faster speed and lower inference cost of the original Sonnet model. While Artifacts provides a robust interactive environment on the web, its functionality remains limited on mobile devices.

Mobile Sync and Vision Capabilities

Anthropic has also expanded its device footprint with native iOS and Android applications. These mobile clients support multi-platform synchronization, allowing developers to start a complex debugging session on their desktop and review the outputs on a mobile device later. The mobile applications integrate native vision capabilities, meaning you can take a photograph of a whiteboard architecture diagram or a physical server error screen and upload it directly for the model to analyze.

Subscription Tiers and Pricing

These features are distributed across three distinct subscription tiers. The Team plan requires a minimum of five users and includes administrative controls for billing and user lifecycle management.

Plan Tier	Pricing	Included Capabilities
Claude Free	$0	Access to Claude 3.5 Sonnet, limited usage
Claude Pro	$20/month	5x Free usage, early feature access, Projects
Claude Team	$30/user/month	Admin tools, Projects, shared chat templates, higher usage

If you build applications using system prompts that require extensive background context, setting up a Claude Project with your core documentation can significantly reduce setup time for daily tasks. Structuring your team’s workflows around these shared folders ensures that every member queries the model against the exact same technical baseline.
