## Arcjet

Arcjet started life as a developer-friendly security layer for web applications and has expanded into runtime security for AI agents. Instead of only checking identity at the door, it evaluates every step an agent takes: which tool is being called, with which typed arguments, by which actor, and in the context of the steps that came before. That lets teams stop unauthorized refunds, unexpected data access, runaway token spend and sequence drift that no single step would have flagged on its own.

The platform combines classic application protections - WAF, bot detection, rate limiting, signup form protection and email validation - with agent-specific controls such as prompt injection detection, tool and MCP authorization, sensitive information detection and data loss prevention. Detection for sensitive data can run locally in your environment so regulated payloads never leave your infrastructure, while decisions and policy versions stream out to SIEM tools like Splunk, Datadog, Panther and Cribl for evidence.

Arcjet ships SDKs for JavaScript and Python ecosystems (Next.js, Astro, Express, Fastify, NestJS, Nuxt, SvelteKit, Hono, Flask, FastAPI, Bun, Deno and more) plus integrations for agent frameworks including LangChain, LangGraph, CrewAI, Google ADK, Mastra, OpenAI Agents, Vercel AI SDK and the Claude Agent SDK. It also offers an MCP server, a CLI and skills for coding agents such as Claude Code, Codex and Cursor. A free trial is available, with paid plans and custom/enterprise pricing on request.

**Pricing & Plans:** Free trial available, then paid plans with custom pricing for larger deployments. Enterprise and volume pricing is quoted on request. Check the official pricing page for current tiers and usage limits.

- **Agent action policy enforcement:** Wrap agent tool calls and get a typed decision - allow, block, redact or hold for review - before the tool actually executes, based on actor, role, route and typed inputs.
- **Prompt injection detection:** Screen user input, fetched web pages, API responses and tool output for hostile instructions before anything reaches the model context.
- **Sensitive information and DLP:** Detect and strip names, addresses, national IDs, bank and card numbers before they reach model context, logs or third-party tools, with optional in-process local detection.
- **Web app protections:** Bot protection, WAF rules, rate limiting, signup form protection and email validation to keep public endpoints and signup flows clean.
- **Audit and observability:** Every decision, policy version and actor is retained as evidence and streamed to Splunk, Datadog, Panther, Cribl or your own analytics warehouse, with OpenTelemetry agent traces.

**Strengths:** Evaluates the whole agent run, not just a single request, which catches sequence drift and multi-step abuse; Detection can run in-process so sensitive data does not have to leave your environment; Broad SDK and agent-framework coverage, including an MCP server, CLI and coding-agent skills; Decisions and policy versions stream to common SIEM and observability stacks for compliance evidence

**Limitations:** Requires code changes inside your application rather than a purely network-level gateway deployment; The breadth of controls and frameworks means a real learning curve for smaller teams; Advanced enterprise governance and custom retention options are quote-based rather than self-serve

## DeepSeek

DeepSeek (Hangzhou DeepSeek Artificial Intelligence Co., Ltd.) is a frontier AI research organization that disrupted the global LLM market by pairing open-weight transparency with breakthrough Mixture-of-Experts (MoE) and reinforcement-learning reasoning efficiency. Following the landmark releases of DeepSeek-V3 and the peer-reviewed DeepSeek-R1 reasoning model, DeepSeek introduced the DeepSeek-V4 generation in 2026—featuring a hybrid attention architecture and a native 1-million-token context window across DeepSeek-V4-Pro (1.6T total parameters, 49B active per token) and DeepSeek-V4.1-Flash (284B total parameters, 13B active per token).

Users can interact with DeepSeek in three ways: completely free through the consumer web portal (chat.deepseek.com) and mobile apps with one-click toggles for deep thinking and live web search; via DeepSeek's hosted, OpenAI-compatible developer API; or by self-hosting DeepSeek's open-weight checkpoints (including V3, R1, Prover-V2, and distilled Qwen/Llama variants) on private infrastructure. The models excel at competitive mathematics, algorithm design, repository-level software engineering, and structured data extraction, with automatic context caching on the API that slashes repeated prompt costs by over 95%.

In late 2026, DeepSeek remains the price-performance benchmark for developers and automation workflows. While the consumer chat interface remains free without a mandatory $20/month subscription tier, the developer API transitioned in late 2026 to two primary endpoints—`deepseek-flash` and `deepseek-v4-pro`—with time-of-day pricing. Off-peak API calls cost just $0.15 per million input tokens ($0.003 on cache hits) and $0.60 per million output tokens on Flash, and $0.66 input / $1.98 output on V4-Pro, making it a fraction of the cost of comparable Western frontier models.

**Pricing & Plans:** Free web and mobile chat app at chat.deepseek.com; pay-as-you-go OpenAI-compatible API with off-peak rates at $0.15/1M input ($0.003 cache hit) and $0.60/1M output for deepseek-flash (V4.1-Flash), and $0.66/1M input ($0.022 cache hit) and $1.98/1M output for deepseek-v4-pro (peak weekday UTC hours bill at 2x).

- **DeepSeek-V4 Hybrid Attention & 1M Context:** Leverages a sparse Mixture-of-Experts architecture (49B active parameters out of 1.6T on V4-Pro) to process up to 1 million tokens with minimal latency and memory overhead.
- **Transparent Chain-of-Thought Reasoning:** Pioneered by DeepSeek-R1 and integrated into V3.2 and V4 thinking modes, exposing step-by-step self-verification for complex math, logic, and code debugging.
- **Automatic Context Caching & Off-Peak API Pricing:** Drops input token costs to $0.003/1M on Flash and $0.022/1M on V4-Pro for cache hits, with 50% lower rates during off-peak UTC hours.
- **Free Consumer Web & Mobile Assistant:** Provides free access at chat.deepseek.com and on iOS/Android with document uploads, reasoning mode, and web search without paywalling core models.
- **Open-Weight Ecosystem & Self-Hosting Freedom:** Offers open weights for DeepSeek-V3, R1, Distill variants, and Prover models on Hugging Face and GitHub so enterprises can deploy within air-gapped environments.

**Strengths:** Completely free consumer web and mobile app with deep reasoning and web search included; Ultra-low API token rates ($0.15/$0.60 on Flash, $0.66/$1.98 on V4-Pro off-peak) with up to 98% savings on cached inputs; Drop-in OpenAI API compatibility makes switching or routing between models effortless; Strong open-weight lineage allows teams to self-host or fine-tune models without vendor lock-in

**Limitations:** Hosted API and web app store data on servers in China, prompting compliance restrictions for some Western enterprises and government agencies; Peak-hour API pricing (01:00–04:00 and 06:00–10:00 UTC on weekdays) doubles per-token costs compared to off-peak rates; Lacks native voice mode, video generation, and productivity suite integrations offered by ChatGPT and Google Gemini
