Company Overview

About Anthropic

Anthropic is a San Francisco-based AI safety and research company that builds the Claude family of large language models. As of 2026, the current Claude 4 generation includes claude-opus-4-6 (most capable, reasoning and agentic tasks), claude-sonnet-4-6 (balanced performance and speed), and claude-haiku-4-5 (fast and cost-efficient). Anthropic also offers Claude Code — an agentic CLI for software engineering — generating $500M+ ARR by mid-2025.

Business Model & Competitive Advantage

Founded in 2021 by Dario Amodei (CEO) and Daniela Amodei (President), along with former OpenAI colleagues including Tom Brown, Chris Olah, Sam McCandlish, Jack Clark, and Jared Kaplan, Anthropic raised $14.3 billion total through 2025 — including $8 billion from Amazon (AWS Bedrock exclusive) and $2 billion from Google (Vertex AI). The company closed a $2.5B Series F in March 2025 and an $8.5B Series F extension in September 2025, reaching a $183B valuation. Revenue hit $5B annualised run-rate by August 2025 (up from $1B at start of 2025).

Competitive Landscape 2025–2026

Anthropic's Constitutional AI (CAI) methodology trains Claude against a set of principles ('the constitution') to be helpful, harmless, and honest — enabling systematic alignment at scale. Claude models feature 200,000-token context windows (the largest among major models), advanced coding capabilities, and the Artifacts feature for live code and content previews. Claude.ai has 18M+ monthly active users. 300,000+ businesses use the Claude API, including integrations with AWS Bedrock, Google Vertex AI, and direct enterprise deployments across healthcare, legal, finance, and developer tooling. The Claude 4 model family, launched May 2025, targets superior reasoning, extended agentic task completion, and improved tool use — competing directly with OpenAI's o3/GPT-4.5, Google Gemini 2.0 Ultra, and Meta Llama 4.

release
claude-agent-sdk-python v0.1.64

### New Features - **SessionStore adapter**: Full SessionStore support at parity with the TypeScript SDK. Includes a `SessionStore` protocol with 5 methods (`append`, `load`, `list_sessions`, `delete`, `list_subkeys`), `InMemorySessionStore` reference implementation, transcript mirroring via `--session-mirror`, session resume from store, and 9 new async store-backed helper functions (`list_sessions_from_store`, `get_session_messages_from_store`, `fork_session_via_store`, etc.). Also adds a 13-contract conformance test harness at `claude_agent_sdk.testing.run_session_store_conformance` for third-party adapter authors (#837) - **Reference SessionStore adapters**: Three copy-in reference `SessionStore` adapters under `examples/session_stores/` — S3 (JSONL part files, mirrors the TS S3 reference), Redis (RPUSH/LRANGE lists + zset index), and Postgres (`asyncpg` + jsonb rows). Not shipped in the wheel; users copy the file they need into their project (#842) ### Internal/Other Changes - Upda

release
claude-agent-sdk-python v0.1.63

### Internal/Other Changes - Updated bundled Claude CLI to version 2.1.114 --- **PyPI:** https://pypi.org/project/claude-agent-sdk/0.1.63/ ```bash pip install claude-agent-sdk==0.1.63 ```

release
claude-agent-sdk-python v0.1.62

### New Features - **Top-level `skills` option**: Added `skills` parameter to `ClaudeAgentOptions` for enabling skills on the main session without manually configuring `allowed_tools` and `setting_sources`. Supports `"all"` for every discovered skill, a list of named skills, or `[]` to suppress all skills (#804) ### Internal/Other Changes - Updated bundled Claude CLI to version 2.1.113 --- **PyPI:** https://pypi.org/project/claude-agent-sdk/0.1.62/ ```bash pip install claude-agent-sdk==0.1.62 ```

release
claude-agent-sdk-python v0.1.61

### Internal/Other Changes - Updated bundled Claude CLI to version 2.1.112 --- **PyPI:** https://pypi.org/project/claude-agent-sdk/0.1.61/ ```bash pip install claude-agent-sdk==0.1.61 ```

release
claude-agent-sdk-python v0.1.60

### New Features - **Subagent transcript helpers**: Added `list_subagents()` and `get_subagent_messages()` session helpers for reading subagent transcripts, enabling inspection of subagent message chains spawned during a session (#825) - **Distributed tracing**: Propagate W3C trace context (`TRACEPARENT`/`TRACESTATE`) to the CLI subprocess when an OpenTelemetry span is active, connecting SDK and CLI traces end-to-end. Install with `pip install claude-agent-sdk[otel]` for optional OpenTelemetry support (#821) - **Cascading session deletion**: `delete_session()` now removes the sibling subagent transcript directory alongside the session file, matching TypeScript SDK behavior (#805) ### Bug Fixes - **Empty setting sources**: Fixed `setting_sources=[]` being silently dropped (treated as falsy), which caused the CLI to load default settings instead of disabling all filesystem settings. An empty list now correctly passes `--setting-sources=` to disable all sources (#822) ### Internal/Other C
