## Agents-Flex

Agents-Flex is an Apache 2.0 open-source framework aimed at Java developers who want to build AI applications and autonomous agents without leaving the JVM ecosystem. It works on JDK 8+ and does not force a Spring dependency, so it can slot into existing enterprise Java stacks cleanly. The entry point is a unified chat model API: configure a provider such as OpenAI with an API key and model name, then call chat() to get a response.

Beyond basic model calls, Agents-Flex is designed as a composable toolkit. You layer in knowledge retrieval (RAG), tools and function calling, multimodality, OCR, and a Skills system where reusable, versionable capability packages combine a SKILL.md description with scripts and assets. A SkillRuntime exposes consistent command, file and search interfaces across local or remote execution targets, so long-running tasks like OCR and video generation can be submitted async and polled by status.

The framework emphasizes architectural clarity and production readiness. Its AgentRunner orchestrates policy and middleware, while a Turn Store persists snapshots and events for long-task recovery. Streaming responses, synchronous image generation and asynchronous task handling are all first-class, and observability hooks help teams operate these systems in production rather than just prototype them.

**Pricing & Plans:** Agents-Flex is free and open source under the Apache 2.0 license. There is no commercial license fee for the framework itself; costs come only from the LLM or cloud providers you connect.

- **Unified chat model API:** Configure any supported provider with an API key and model name, then call chat() for a consistent interface across models.
- **Agent orchestration:** AgentRunner combines policy and middleware to coordinate models, tools and sandboxes inside a single execution flow.
- **Skills packages:** Reusable, versionable capability definitions that bundle a SKILL.md, scripts and assets, discovered from local directories or remote storage.
- **RAG, multimodality & OCR:** Add knowledge retrieval, image generation and OCR pipelines on demand, mixing synchronous and asynchronous execution styles.
- **Production runtime:** A Turn Store persists snapshots and events so long-running tasks can recover, supported by streaming responses and observability.

**Strengths:** Apache 2.0 open source with a permissive license for commercial use; Java-native design that fits existing JVM and enterprise stacks; Composable architecture covering RAG, tools, Skills and OCR in one framework; Async task handling and a Turn Store for reliable long-running workloads

**Limitations:** Documentation and community content skew toward Chinese, which may slow English-only teams; As a younger framework, the surrounding ecosystem is smaller than more established Python options; Requires Java expertise, so it is not aimed at non-developers

## 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
