Bloom vs Grok Code Fast 1

Bloom and Grok Code Fast 1 are both large language models tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

Bloom

Bloom generates targeted evaluation suites for arbitrary behavioral traits.

Grok Code Fast 1

<cite index="2-1">Released in late August 2025, the xAI Grok Code Fast 1 model is a coding-focused AI model that excels at common, high-volume coding task and is designed especially for agentic coding workflows.</cite> <cite index="1-6,1-7,1-8">Built from scratch with a brand-new model architecture, it was trained on a pre-training corpus rich with programming-related content, and curated high-quality datasets that reflect real-world pull requests and coding tasks.</cite> <cite index="1-23">The model is particularly adept at TypeScript, Python, Java, Rust, C++, and Go.</cite> <cite index="1-13">The model is generally available via the xAI API, priced at $0.20 / 1M input tokens, $1.50 / 1M output tokens, and $0.02 / 1M cached input tokens.</cite>

Released	2025-12-20	2025-08-28
Pros	Reproducible and targeted evaluations that quantify frequency and severity across automatically generated scenarios Evaluations correlate strongly with hand-labelled judgments and reliably separate baseline models from intentionally misaligned ones Researchers can extensively configure Bloom's behavior, through choosing models for each stage, adjusting interactions' length and modality Using Bloom evaluations took only a few days to conceptualize, refine and generate Integrates with Weights & Biases for experiments at scale and exports Inspect-compatible transcripts	<cite index="2-25,2-26">Massive throughput of approximately 90-100 tokens per second, delivering dozens of tool calls and edits before you finish reading its initial plan in IDE integrations</cite> <cite index="1-13">Economical pricing at $0.20/1M input tokens and $1.50/1M output tokens</cite> <cite index="2-27,2-28,2-29">Visible reasoning traces that provide real-time, summarized view of its reasoning process, helping developers catch logic errors early</cite> <cite index="1-22">Prompt caching optimizations regularly achieving cache hit rates above 90% when used with launch partners</cite>
Cons	Bloom is only as robust as the seeds and judging logic that power it; teams should treat seeds as living governance artifacts, and for ambiguous or highly contextual behaviors, periodic manual review is still necessary Bloom's evaluation suite is unlikely to match the precise distribution of scenarios found in existing benchmarks, and since model behavior can be sensitive to context and prompt variations, direct comparisons are unreliable	<cite index="6-31,6-34">Potential gaps in training on specific frameworks; poor performance on Tailwind CSS v3 tasks, suggesting possible smaller model size limitations</cite> <cite index="6-36">Its reasoning model nature makes it unsuitable for interactive workflows requiring fast responses despite fast token throughput</cite>

Bottom line

Bloom is free while Grok Code Fast 1 is paid. Choose based on which difference matters most for your workflow.
