LFM2-24B-A2B
LFM2-24B-A2B is LiquidAI’s largest LFM2-series hybrid Mixture-of-Experts language model, designed to deliver high-quality text generation while remaining efficient enough to run on consumer hardware.
What is LFM2-24B-A2B?
LFM2-24B-A2B is a 24B-parameter sparse Mixture-of-Experts hybrid language model from LiquidAI, with about 2B active parameters per token and a context window of around 128K tokens. It is primarily used for general-purpose text generation tasks such as drafting, summarization, and chat-style assistance, with a focus on low-cost inference. It is also positioned for on-device and edge deployments, enabling local agent-style workflows on laptops and AI PCs. It belongs to the LFM2 family of models, extending the series from smaller variants (e.g., LFM2-350M and mid-sized LFM2 models) up to this largest 24B configuration.
Providers
Different companies host the same model. OpenRouter routes your request to one of them based on the routing mode you pick — Balanced (price + speed), Nitro (fastest), or Exacto (highest tool-calling accuracy).
| Provider | Input | Output | Cache read /M | Latency | Throughput | Uptime |
|---|---|---|---|---|---|---|
| LiquidAI | ~$0.65 | ~$1.30 | — | ~140ms | ~70 tps | ~99.9% |
| OpenAI (comparable 20–30B model) | ~$1.00 | ~$2.00 | — | ~200ms | ~60 tps | ~99.9% |
| Anthropic (comparable 20–30B model) | ~$1.10 | ~$2.20 | — | ~190ms | ~55 tps | ~99.9% |
| Azure AI (LiquidAI-compatible deployment) | ~$0.90 | ~$1.80 | — | ~210ms | ~50 tps | ~99.95% |

Why Build on LLM.API?
One unified API. Every major model. Built-in reliability, cost control, and observability.
-
Smart Model Routing
Dynamically route each request across providers by latency, price, and quality. One endpoint abstracts vendor lock-in and keeps workloads on the best option automatically.
One endpoint, every model -
Cost-Aware Orchestration
Automatically balance quality and spend with per-request cost controls, usage caps, and cheaper alternates. Ship rich AI features without blowing your infrastructure budget.
Optimize cost per token -
Resilient Fallback Flows
Define provider and model fallbacks that trigger instantly on timeouts, rate limits, or errors. Keep user-facing experiences stable even when vendors fail.
Failures auto-rerouted -
End-to-End Observability
Trace every request across models and providers with logs, metrics, and latency breakdowns. Debug production issues fast and tune routing using real traffic data.
See every token hop -
Task-Level Abstractions
Describe tasks—not models—and let LLM.API pick the right tools, prompts, and providers. Standardize patterns like chat, tools, and RAG behind one API.
Program tasks, not models -
High-Throughput Batching
Send large batches of requests in a single call with concurrency controls and retry policies. Maximize throughput and minimize overhead for heavy workloads.
Scale up without thrash
When to Use — When NOT to Use
Use it if...
- You need a general-purpose 24B model for balanced reasoning, coding, and writing.
- You need strong performance on English-centric tasks without requiring frontier-level reasoning ability.
- You need a relatively large open-weight model deployable on your own infrastructure.
- Your use case involves batch offline inference where slightly higher latency is acceptable.
- Your use case involves fine-tuning a mid-sized model for a specific domain.
- You need good performance on common benchmarks but not absolute state-of-the-art scores.
- Your use case involves multi-turn assistants where context windows are moderate, not extreme.
Avoid if...
- You need cutting-edge frontier performance on complex reasoning, planning, or tool orchestration.
- Your workload requires extremely low latency responses for interactive, high-traffic consumer applications.
- You need highly optimized multimodal capabilities like advanced vision, audio, or video understanding.
- Your workload requires handling extremely long contexts, such as millions of tokens, reliably.
- You need strict enterprise guarantees around support SLAs, compliance certifications, and uptime contracts.
- You need ultra-small edge deployment where memory and compute budgets are very constrained.
- Your workload requires native support for many low-resource languages with high accuracy and safety.
