Implements a two-phase inference architecture where the model allocates additional compute tokens (up to 32K thinking tokens) to internal reasoning before generating responses. Uses a hidden reasoning layer that performs step-by-step problem decomposition, hypothesis testing, and self-correction without exposing intermediate thoughts to the user. The thinking phase operates on a separate token budget from the response phase, enabling the model to spend variable compute time on problem complexity.

Unique: Separates thinking tokens from response tokens with a dedicated hidden reasoning phase, allowing variable compute allocation per query without exposing intermediate reasoning steps. This differs from standard chain-of-thought which exposes all reasoning in the output.

vs alternatives: Achieves 83.3% on IMO qualifying exams and 89th percentile on Codeforces by allocating compute to internal reasoning rather than relying on single-pass generation like GPT-4, with the tradeoff of higher latency.

Leverages extended reasoning to achieve expert-level performance on physics, chemistry, and biology problems through multi-step verification and constraint satisfaction. The model internally validates solutions against physical laws, chemical equilibrium principles, and biological mechanisms before responding. Trained on scientific reasoning patterns that enable it to catch errors, consider alternative approaches, and provide rigorous justification.

Unique: Achieves PhD-level performance through internal verification loops that check solutions against domain-specific constraints and principles, rather than relying on pattern matching. The hidden reasoning phase enables the model to catch errors and reconsider approaches without exposing failed attempts.

vs alternatives: Outperforms GPT-4 and Claude on STEM benchmarks (83.3% IMO, 89th percentile Codeforces) by dedicating compute to verification and constraint satisfaction rather than single-pass generation.

Generates optimized code solutions for competitive programming problems by reasoning through algorithmic complexity, edge cases, and optimization strategies during the thinking phase. The model evaluates multiple approaches (brute force, dynamic programming, greedy, etc.), analyzes time/space complexity, and selects the optimal strategy before generating code. Handles problems requiring careful input parsing, constraint satisfaction, and numerical stability.

Unique: Achieves 89th percentile on Codeforces by reasoning through algorithmic tradeoffs and complexity analysis in the thinking phase, then generating optimized code. This differs from standard code generation which may produce correct but suboptimal solutions.

vs alternatives: Outperforms GPT-4 on competitive programming by allocating compute to algorithm selection and complexity verification rather than direct code generation, achieving 89th percentile vs typical 50-60th percentile performance.

Generates rigorous mathematical proofs by reasoning through logical steps, constraint satisfaction, and symbolic manipulation during the thinking phase. The model constructs proofs incrementally, verifying each step against mathematical axioms and previously established results. Handles problems requiring induction, contradiction, case analysis, and algebraic manipulation with formal rigor.

Unique: Achieves 83.3% on IMO qualifying exams by reasoning through proof strategies and constraint satisfaction in the thinking phase, then generating formal proofs. This differs from standard language models which may generate plausible-sounding but logically invalid proofs.

vs alternatives: Outperforms GPT-4 on mathematical reasoning by allocating compute to logical verification and proof strategy selection rather than pattern-based generation, achieving 83.3% on IMO vs typical 30-40% performance.

Provides a 200,000 token context window that accommodates large codebases, long documents, and extensive problem specifications. The context budget is separate from the thinking token budget (up to 32K), allowing the model to maintain awareness of large amounts of reference material while reasoning through complex problems. Enables processing of entire files, documentation, and multi-file code analysis without truncation.

Unique: Separates context tokens (200K) from thinking tokens (32K), allowing large reference materials to be maintained while reasoning is allocated separately. This differs from standard models where context and reasoning share the same token budget.

vs alternatives: Provides 2.5x larger context window than GPT-4 (200K vs 128K) with dedicated thinking tokens, enabling analysis of larger codebases and documents without sacrificing reasoning capability.

Detects and corrects errors during the reasoning phase by internally testing solutions against constraints, edge cases, and domain principles. The model generates candidate solutions, evaluates them, identifies failures, and iterates without exposing failed attempts to the user. This self-correction loop is performed in the hidden thinking phase, resulting in higher-quality final responses.

Unique: Performs error detection and correction in the hidden thinking phase, resulting in higher-quality final responses without exposing failed attempts. This differs from chain-of-thought approaches where all reasoning (including errors) is visible.

vs alternatives: Achieves higher correctness rates than standard models by internally testing solutions and iterating, with the tradeoff of higher latency and reduced transparency into reasoning process.

Systematically identifies and handles edge cases and constraints during the reasoning phase by enumerating boundary conditions, special cases, and constraint violations. The model reasons through input validation, numerical edge cases (overflow, underflow, division by zero), and domain-specific constraints before generating solutions. This enables robust solutions that handle corner cases correctly.

Unique: Systematically enumerates and handles edge cases during the reasoning phase rather than relying on pattern matching, resulting in more robust solutions. This differs from standard code generation which may miss edge cases.

vs alternatives: Produces more robust code than GPT-4 by reasoning through edge cases and constraints explicitly, with the tradeoff of higher latency and reduced transparency into edge case analysis.

Allocates compute dynamically based on problem complexity, spending more thinking tokens on harder problems and fewer on simpler ones. The model estimates problem difficulty and adjusts the reasoning phase duration accordingly, resulting in variable latency (5-30 seconds) depending on problem complexity. This adaptive allocation improves efficiency compared to fixed-latency approaches.

Unique: Allocates thinking tokens adaptively based on problem complexity rather than using fixed compute budgets, resulting in variable latency optimized for efficiency. This differs from standard models with fixed inference time.

vs alternatives: More efficient than fixed-latency approaches by allocating more compute to harder problems and less to simpler ones, but less predictable than models with fixed response times.

Captures desktop screenshots and feeds them to 100+ integrated vision-language models (Claude, GPT-4V, Gemini, local models via adapters) to reason about UI state and determine appropriate next actions. Uses a unified message format (Responses API) across heterogeneous model providers, enabling the agent to understand visual context and generate structured action commands without brittle selector-based logic.

Unique: Implements a unified Responses API message format abstraction layer that normalizes outputs from 100+ heterogeneous VLM providers (native computer-use models like Claude, composed models via grounding adapters, and local model adapters), eliminating provider-specific parsing logic and enabling seamless model swapping without agent code changes.

vs alternatives: Broader model coverage and provider flexibility than Anthropic's native computer-use API alone, with explicit support for local/open-source models and a standardized message format that decouples agent logic from model implementation details.

Provisions isolated execution environments across macOS (via Lume VMs), Linux (Docker), Windows (Windows Sandbox), and host OS, with unified provider abstraction. Handles VM/container lifecycle (creation, snapshot management, cleanup), resource allocation, and OS-specific action handlers (keyboard/mouse events, clipboard, file system access) through a pluggable provider architecture that abstracts platform differences.

Unique: Implements a pluggable provider architecture with unified Computer interface that abstracts OS-specific action handlers (macOS native events via Lume, Linux X11/Wayland via Docker, Windows input simulation via Windows Sandbox API), enabling single agent code to target multiple platforms. Includes Lume VM management with snapshot/restore capabilities for deterministic testing.

vs alternatives: More comprehensive OS coverage than single-platform solutions; Lume provider offers native macOS VM support with snapshot capabilities unavailable in Docker-only alternatives, while unified provider abstraction reduces code duplication vs. platform-specific agent implementations.
