## Claude

Claude is Anthropic's flagship AI assistant, renowned among software engineers, writers, and enterprise analysts for its natural prose, low hallucination rates, and sustained agentic execution. While the legacy directory slug still references 2023's 'Claude 2', both the Claude 2 and Claude 3/3.5/3.7 generations have been fully retired. As of late 2026, claude.ai runs on the Claude 5.5 generation—led by Claude Opus 5.5 (released September 2026), Claude Sonnet 5.5 for rapid everyday tasks and coding, and Claude Haiku 5.5—supporting up to a 1-million-token context window, 128K output tokens, and adaptive extended thinking.

Inside the web, desktop, and mobile apps, Claude functions as a full production workspace rather than a simple chat box. Users organize persistent knowledge bases with custom instructions in Projects, render and edit live React applications, SVGs, mermaid diagrams, and formatted slide decks side-by-side in Artifacts, and connect external SaaS tools via the open Model Context Protocol (MCP) and native web search. Paid subscribers also gain access to Claude Code—Anthropic's terminal and IDE agent capable of autonomous multi-file engineering across entire codebases—and Claude Cowork for collaborative enterprise task execution.

Anthropic structures Claude's 2026 pricing around compute capacity and team governance. The Free tier offers daily access to Sonnet 5.5, while Claude Pro ($20/month or $17/month billed annually) unlocks Opus 5.5, extended thinking, Projects, and entry-level Claude Code access. Heavy individual builders can upgrade to Claude Max at $100/month (5x Pro capacity) or $200/month (20x Pro capacity), while organizations can mix Team Standard seats ($20/seat/month annual) and Team Premium seats ($100/seat/month annual with 5x capacity and full Claude Code access) or adopt usage-based Enterprise contracts with audit logs and SCIM.

**Pricing & Plans:** Free tier ($0); Claude Pro at $20/mo ($17/mo billed annually at $200/yr); Claude Max at $100/mo (5x Pro usage) or $200/mo (20x Pro usage); Team Standard at $25/seat/mo ($20/mo annual) and Team Premium at $125/seat/mo ($100/mo annual); Enterprise from $20/seat/mo + API usage.

- **Claude 5.5 Model Family & Adaptive Thinking:** Combines frontier Claude Opus 5.5 and high-speed Sonnet 5.5 with configurable extended thinking, up to 1M-token context windows, and 128K-token outputs.
- **Claude Code & Claude Cowork Included on Paid Plans:** Pro, Max, and Team Premium plans bundle Claude Code for autonomous command-line software engineering, test execution, and repository-wide refactoring.
- **Interactive Artifacts & Document Generation:** Renders live interactive web apps, visualizations, spreadsheets, and formatted PowerPoint decks in a dedicated workspace panel alongside the chat.
- **Projects & Model Context Protocol (MCP):** Grounds conversations in shared project knowledge bases and connects directly to local filesystems, GitHub, Slack, and internal databases via MCP.
- **Constitutional AI Safety & Enterprise Governance:** Trained on Anthropic's updated 2026 Constitution with strict privacy guarantees, SSO, SCIM provisioning, and HIPAA-ready healthcare configurations.

**Strengths:** Top-tier coding, bug-fixing, and agentic planning performance powered by Claude Opus 5.5 and Sonnet 5.5; Natural, nuanced writing style that avoids the repetitive clichés common in competing LLMs; Claude Max ($100/mo 5x and $200/mo 20x) and mixed Team Standard/Premium seats provide clear scaling for heavy Claude Code users; Open Model Context Protocol (MCP) ecosystem enables deep, standardized connections to local tools and enterprise data

**Limitations:** No native photorealistic image or video generation inside claude.ai (limited to SVGs, code charts, and diagrams); Free tier does not include Claude Code and hits 5-hour rolling message limits quickly during long-context chats; Pro users ($20/mo) who rely heavily on Opus 5.5 or Claude Code can still exhaust their 5-hour rolling window and require Max ($100/mo)

## EvalCore

EvalCore solves a common failure mode in AI engineering: you tweak a prompt, swap a model, or bump a dependency, and something quietly breaks in production. Instead of trying to re-run expensive, non-deterministic model calls in CI, EvalCore treats AI behaviour like a snapshot. An eval is just a YAML file describing a target and a JSONL dataset, with scorers stacked on top to define what "good" means.

The first run happens live against a real model — anything OpenAI-compatible, vLLM, Ollama, a custom REST API, a shell command, or OpenTelemetry/OpenInference traces. Every request and response is written to a local SQLite cassette, keyed by a hash of the canonical request, along with token and cost figures on the summary. From then on, CI replays those recordings byte-for-byte with `--cache replay`: no network, no API keys, no flaky judge model, and identical inputs always produce identical verdicts.

Because the cassette is committed to your repository, a `--baseline main` comparison fails only on genuine regressions, and the process exit code gates the pipeline. Trials, model comparisons, agent traces, gates, and reports are all a few lines of YAML or a flag rather than a framework. It ships as one small Rust binary, works with any language on the other side of the target, and collects no telemetry.

**Pricing & Plans:** Free and open source under the Apache-2.0 licence, with $0 cost in CI thanks to offline cassette replay. Install via cargo or prebuilt binaries; no signup, no server and no telemetry.

- **Record once, replay forever:** A live run captures every model request and response into a local SQLite cassette that CI can replay offline and deterministically at zero cost.
- **Anything can be a target:** Point EvalCore at OpenAI-compatible endpoints, vLLM, Ollama, your own REST APIs, shell commands, or OTel/OpenInference traces — no SDK required.
- **Scorers that define 'good':** Stack contains, judge-rubric and other scorers in YAML to express exactly what a correct answer looks like for each case.
- **Regression gates and baselines:** Compare against a baseline branch so only real regressions fail, and let the process exit code gate your pull requests.
- **Cost, tokens and reports built in:** Every summary reports token usage and spend for live runs, while trials, model comparisons and history give you a clear picture over time.

**Strengths:** Genuinely free and open source under Apache-2.0, with no usage-based pricing; Deterministic offline replay removes flaky, expensive model calls from CI; Single dependency-free binary that works regardless of your app's language; Configuration is plain YAML plus JSONL, so suites are easy to review and version

**Limitations:** Requires a Rust toolchain or a prebuilt binary and comfort with the command line; Cassettes must be recorded live first, so initial setup needs real API access; No hosted dashboard — results and history live in your repo and CI logs
