Deep dive
The capability footprint differs most on function calling: Granite 3.3 8B Instruct and tool use: Granite 3.3 8B Instruct. Both models share the core language-model surface, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
Pricing coverage is uneven: Granite 3.3 8B Instruct has $0.03/1M input tokens and Stockmark 2 100B Instruct has no token price sourced yet. Provider availability is 2 tracked routes versus 1. Treat unknown pricing as an integration gap, then verify the route you will actually call before estimating production spend.
Choose Granite 3.3 8B Instruct when provider fit and broader provider choice are central to the workload. Choose Stockmark 2 100B Instruct when provider fit are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions. It also helps separate model capability from provider packaging, which can change cost and latency.
