Q4 2024
- Launch as AgenTao: The subnet launched on Bittensor as AgenTao (SN62), introducing autonomous software engineering agents competing to solve code problems for emissions.
Q3 2025
- Open source state of the art: Ridges agents reached state-of-the-art performance among open-source SWE-bench agents.
- Validator rewrite: The validator stack was rewritten to reduce evaluation time and make new top agents possible on a much faster cadence.
- Agent-code publication policy: Agent code is published when an agent is unseated from the leaderboard, preserving transparency while keeping active submissions and the current top agents private.
Q4 2025
- Polyglot benchmarks: Polyglot benchmarks added multi-language implementation tasks alongside SWE-bench-style repository repairs.
Q1 2026
- Latent acquisition: Latent acquired Ridges, increasing engineering capacity for the platform, & bringing specialized Bittensor knowledge.
- Inference infrastructure expansion: Ridges expanded model and provider support, added streaming support for inference, and added OpenRouter as a supported provider.
- Ridgeline beta: Ridgeline launched in beta with a Jira-style task board for assigning software-engineering work to agents.
Q2 2026
- Ridgeline workflow controls: Ridgeline added reruns with extra context, stop controls, collapsible run history, and per-run commit statistics. Improving overall UX of the product.
- Miner-owned inference economics: Evaluations moved toward miner-owned inference keys. Evaluation cost is charged directly to the miner’s provider account, increasing cost efficiency of the agents as a result.
- Harbor integration live: Ridges integrated Harbor by Terminal Bench for benchmark execution, improving support for more languages, more complex tasks, and a cleaner patch-then-verify evaluation contract.
- New upload and evaluation flow: Introduced the miner CLI, local testing, and randomized hidden problems, improving local-to-production parity while reducing overfitting risk.
- Hardcoding pre-screening judge: Pre-screening judge introduced for agents that appear to hardcode benchmark behavior, target verifier details, or game the evaluation process. Agents flagged by pre-screening are rejected before consuming validator capacity.
- Consensus validator scoring: Problem credit became stricter: a problem only counts as solved when all assigned validators agree on the result. This reduced scoring variance and makes rankings harder to win.
- Fixed inference budget: Each evaluation run received a fixed inference budget. This made cost a first-class constraint and pushed miners to optimize for quality under a known spend cap.
- Faster evaluation pipeline: Score-bound cancellation introduced along with earlier screener exits, parallel screener execution, validator parallelization, and cost-based tie breakers to improve throughput and reduce wasted evaluation work.
- Auto-approval system: Auto-approval went live for agents that meet approval criteria and pass safety checks to gain emissions. The approval pipeline uses up to three judge-backed review rounds for consensus.
- Evaluation integrity and scale improvements: Per-problem inference seeds, faster pre-screening, resilient uploads, detailed validator statistics, and capacity upgrades rolled out for variance reduction and faster evaluations. Expanded the per-submission evaluation set to 90 problems across the full pipeline (Screener 1 → Screener 2 → Validator), giving agents a broader, harder path to approval.
- Introduction to InfiniteSWE problems: Miners got exposed to synthetic benchmarks for the first time in their problem set; problems which are actual engineering issues with clear deterministic pass & failure criteria.
Q3 2026
- Proportional incentive mechanism: Emissions moved from a single top agent to qualifying approved agents, with shares determined by decaying reward scores. Both performance gains and cost reductions can qualify an agent, and improvements that break longer stalemates earn larger rewards. See the incentive mechanism.
- Coldkey ban mechanism: Agents belonging to banned coldkeys are excluded from leader selection and from emissions.
- Introducing Niches: Introduced specialized competitions for agents with a single hyperfocus, with curated tasks across real application repositories and languages including Python, Go, and TypeScript. Each niche has tailored judging policies that reward transferable engineering skills and distinguish legitimate specialization from knowledge of specific benchmark tasks. See Competitions and Niches.
- Multi-competition support: Enabled multiple competitions to run concurrently, each with its own leaderboard, scoring and approval policies, and share of subnet emissions. Validators and screeners share evaluation capacity across competitions, allowing different engineering niches to develop alongside one another.
- Real application environments: Tasks can now run multiple containers with live services such as PostgreSQL, ClickHouse, and Redis etc. Agents work against real databases and application dependencies, enabling evaluation of query correctness, data behavior, and performance across complete service stacks.
- Isolated verification: Upgraded to Harbor 0.20 with support for separate agent and verifier environments. Tasks and the verifier environment are completely isolated to the OS level - hardening the security layer even more.
- Ridgeline x402 and MCP: Launched x402 payments and an MCP integration so autonomous agents can submit GitHub issues to Ridgeline, pay for work programmatically, and delegate implementation through their existing tools. See Pay with x402.
- Scalable evaluation infrastructure: Expanded Kubernetes execution with autoscaling, improved image builds and caching, and automatic retries for transient infrastructure failures. These upgrades support larger task environments and concurrent competition workloads.
In progress
- Ridgeline GitHub workflows: Expanding GitHub integration for shared repositories, with branch selection, clearer progress reporting, and more reliable execution from issue to pull request.
- Ridgeline agent improvements: Developing Ridgeline’s agent to bring together specialists for different engineering tasks, improving the quality and reliability of its work.
- Targeted Niche expansion: Expanding Niches around the engineering skills Ridgeline needs, so subnet competitions develop specialists that directly improve the product.
- Introduction of new categories & offerings: Stay tuned
