AWS Bedrock

Amazon Web Services, Inc.

Paid

Fully managed AWS service that provides access to multiple high-performing foundation models and tools to deploy and operate generative AI agents.

Key features

  • Multi-Model Access: Provides API access to a catalog of foundation models from multiple providers (examples in community repos include Claude, Llama, Mistral, and AWS Titan), enabling developers to choose models by capability and cost.
  • Fully Managed Service: Abstracts hosting, scaling, and model maintenance so teams can invoke models via Bedrock APIs without managing underlying infrastructure or model serving.
  • Agent Tools and Orchestration: Includes tools, reference agent implementations, and support for multi-agent orchestration (Bedrock agents and Bedrock Flow patterns) to build conversational agents that interact with AWS services and external APIs.
  • AWS Integration and Automation: Integrates with AWS services (Lambda, S3, Systems Manager, IAM, etc.) to run automation workflows, invoke runbooks, and securely manage access and roles for production automation.
  • OpenAPI/OpenAI Compatibility Options: Community projects and AWS samples provide proxy patterns and SDK adapters so existing OpenAI-based code and tools can be routed to Bedrock models without changing application code.
  • Samples, SDKs and IaC Support: Official and community sample repositories, AWS SDK support, and infrastructure-as-code constructs (CDK, Serverless examples) accelerate prototyping, deployment, and CI/CD of generative AI apps.
  • Security and Access Controls: Leverages AWS IAM and Secrets Manager for controlled access, API key management, and region-specific availability tied to AWS account controls and governance.
  • Managed hosting and invocation of multiple foundation models (examples: Claude 3 Opus/Sonnet/Haiku, Llama 2/3, Mistral/Mixtral, etc.)
  • Bedrock Agents and Bedrock Flow for building, orchestrating and operating multi-agent systems
  • Knowledge Bases with direct integration to structured data stores and automatic NL-to-SQL conversion for queries
  • OpenAI-compatible proxy option to call Bedrock models through existing OpenAI APIs/SDKs without code changes
  • Official AWS SDK support (Python and other AWS SDKs) and CLI integration for model invocation and management
  • Infrastructure-as-Code modules and examples (AWS CDK Generative AI Constructs, Terraform modules, Serverless templates)
  • Integration building blocks for AWS Lambda, Amazon S3, AWS Secrets Manager, IAM roles/policies, and Amazon Location Service
  • Sample code and community repositories for fine-tuning, prompt engineering, retrieval-augmented generation, and agent examples
  • Support for custom models and Bedrock-specific resources via AWS resource types (custom model, agents, knowledge-base connectors)
  • Monitoring and observability options via CloudWatch and companion tools (e.g., LangSmith, LangChain integrations)

Best for

  • Generative Application Development: Build chatbots, summarizers, and content generation services that select the most appropriate foundation model for cost, latency, or quality via Bedrock APIs.
  • Agent-Based Automation for Cloud Operations: Deploy Bedrock agents that provide natural-language interfaces to AWS Support Automation Workflow runbooks to troubleshoot and remediate AWS resources automatically.
  • Multi-Agent Orchestration: Orchestrate specialist agents (e.g., retrieval, planning, execution) using Bedrock Flow and community frameworks to maintain context and deliver coherent, multi-step AI-driven user experiences.
  • Model Evaluation and Migration: Test and compare multiple foundation models (including via OpenAI-compatible proxies) without changing existing codebases to evaluate suitability for specific tasks or to migrate workloads.
  • Customer Care and Industry Integrations: Integrate generative agents with industry APIs (for telco, location services, CRM) and AWS backends to create personalized support, routing, and automation workflows.
  • Retrieval-Augmented Generation (RAG): Combine Bedrock models with AWS storage and search services to implement RAG pipelines for knowledge-grounded Q&A, documentation assistants, and domain-specific summarization.
  • Build conversational agents and virtual assistants that orchestrate multiple specialized agents using Bedrock Flow
  • Migrate applications built against OpenAI APIs to run on Bedrock using an OpenAI-compatible proxy
  • Create retrieval-augmented generation (RAG) systems and use Knowledge Bases to query structured data stores with natural language
  • Automate AWS troubleshooting and runbook execution by pairing Bedrock Agents with AWS Systems Manager automation documents and Lambda
  • Embed foundation models into serverless backends and telecom or location-aware applications (examples integrating Amazon Location Service and Telco APIs)

SWE-2

Cognition

Paid

Cognition's coding model that scores 50.0% on FrontierCode 1.1 Main at 64% lower cost than comparable frontier models.

Key features

  • Pareto-Frontier Cost Efficiency: Matches GPT-5.6 Sol and Fable 5/5.1 on coding benchmarks at a fraction of their price and comes within a few points of GPT-6 Astra at roughly a quarter of the cost.
  • Single-Run Multi-Effort RL: A reinforcement learning algorithm trains all reasoning-effort levels in one run, applying a per-level linear cost penalty derived from the base model's local frontier slope.
  • Focused Codebase Exploration: Stronger engineering judgment lets the model decide which parts of a repository matter, cutting mean steps per run from 127 to 53 at medium effort.
  • Selectable Effort Levels: Ships medium, high and max reasoning settings so teams can trade additional steps and cost for accuracy on harder tasks.
  • End-to-End Test Writing: Produces tests that validate an implementation end to end, catching regressions and edge cases more reliably than previous SWE models.
  • Resourceful Task Recovery: When an expected route is blocked — an unavailable MCP integration, for example — it finds an alternative path to the same answer within the user's stated boundaries.
  • Efficient Training and Serving Stack: NVFP4/FP8 kernels, quantization-aware training and an online draft model cut memory use and train-inference mismatch despite nearly 3x the base parameters of SWE-1.7.
  • Hardened Verifier Flywheel: Triples the number of RL environments, adds instruction-following overlays, and uses earlier SWE-2 checkpoints to iteratively strengthen verifiers.

Best for

  • Agentic Software Engineering: Powering Devin sessions that plan, edit, build and test changes across a real repository with minimal supervision.
  • Cost-Sensitive Coding at Scale: Teams running large volumes of automated coding tasks pick a model that holds frontier-adjacent accuracy at a materially lower per-task cost.
  • Terminal and Tooling Workflows: Strong Terminal-Bench results suit tasks driven through shell commands, build systems and command-line tooling.
  • Regression Test Generation: Generating end-to-end tests for existing implementations to catch edge cases before a release.
  • Effort-Tiered Task Routing: Routing simple tickets to medium effort and hard migrations to high or max effort within the same model deployment.
  • Benchmark and Model Evaluation: Engineering leaders compare coding model options on published FrontierCode, DeepSWE and Terminal-Bench numbers alongside cost.
