A side-by-side comparison of Freesolo Flash and Side Space 2.0 — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Freesolo Flash
Freesolo
Post-training platform driven by AI coding agents like Claude Code and Cursor — returns deployable specialized models.
Key features
- Agent-Driven Workflow: Claude Code, Cursor, or Codex describe the run in natural language and launch training
- Fixed-Price Quotes: Flash returns one quote and ETA up front — no per-token metering or GPU-hour surprises
- SFT + GRPO Pipeline: Supervised fine-tuning followed by reinforcement learning past the frontier baseline
- Custom Kernels: FlashAttention, fused SwiGLU, RMSNorm, RoPE and QK-norm optimized per model architecture
- Exportable Weights: Every run returns downloadable weights in standard formats to serve on your own infrastructure
- Data Isolation: Encrypted in transit and at rest, never used to train anything but your model
- Reproducible Runs: Pinned configs, seeds, and checkpoints so every run always finishes
Best for
- Turn generic LLM capability into a specialized production feature for your product
- Have an AI coding agent orchestrate the entire fine-tuning loop without leaving your IDE
- Retrain small specialized models on the fly as your task data evolves
- Route the 90% routine tail of LLM calls (classify, extract, rerank, moderate) to a cheap specialized model
- Beat a frontier model's zero-shot accuracy on a domain task with a sub-10B tuned model
- Keep model weights in-house instead of relying on hosted API-only fine-tuning
